This paper analyzes text data security and compression techniques using Huffman coding. It provides an overview of data compression techniques, focusing on lossless compression. Huffman coding is described as an optimal technique that uses a prefix code generation process to assign unique codes to symbols based on their frequency. While Huffman coding provides effective compression and security, issues can arise with its binary tree implementation. The paper concludes that Huffman coding is widely used but has execution challenges, and an optimal solution can be found through further analysis.

Efficient Similarity Search over Encrypted Data
This document summarizes a research paper that proposes an efficient method for similarity search over encrypted data stored in the cloud. The method uses Locality Sensitive Hashing (LSH) to index the encrypted data and generate "trapdoors" or encodings of search queries. When a user submits a query, the trapdoor is generated and similarity search is performed by finding the similarity between the query trapdoor and the encrypted data indexes stored in the cloud, without decrypting the actual data. The paper outlines the data uploading and query processing steps, which include preprocessing, encryption, trapdoor generation using LSH-based bucketing of n-grams from the query terms, and using Bloom filters for efficient similarity matching during search.
Duplicate File Analyzer using N-layer Hash and Hash Table
with the advancement in data storage technology, the cost per gigabyte has reduced significantly, causing users to negligently store redundant files on their system. These may be created while taking manual backups or by improperly written programs. Often, files with the exact content have different file names; and files with different content may have the same name. Hence, devising an algorithm to identify redundant files based on their file name and/or size is not enough. In this paper, the authors have proposed a novel approach where the N-layer hash of all the files are individually calculated and stored in a hash table data structure. If an N-layer hash of a file matches with a hash that already exists in the hash table, that file is marked as a duplicate, which can be deleted or moved to a specific location as per the user's choice. The use of the hash table data structure helps achieve O(n) time complexity and the use of N-layer hashes improve the accuracy of identifying redundant files. This approach can be used for folder specific, drive specific or a system wide scan as required.

A Review on Text Mining in Data Mining
Data mining is the knowledge discovery in databases and the gaol is to extract patterns and knowledge from
large amounts of data. The important term in data mining is text mining. Text mining extracts the quality
information highly from text. Statistical pattern learning is used to high quality information. High –quality in
text mining defines the combinations of relevance, novelty and interestingness. Tasks in text mining are text
categorization, text clustering, entity extraction and sentiment analysis. Applications of natural language
processing and analytical methods are highly preferred to turn
Using Cisco Network Components to Improve NIDPS Performance
Network Intrusion Detection and Prevention Systems (NIDPSs) are used to detect, prevent and
report evidence of attacks and malicious traffic. Our paper presents a study where we used open
source NIDPS software. We show that NIDPS detection performance can be weak in the face of
high-speed and high-load traffic in terms of missed alerts and missed logs. To counteract this
problem, we have proposed and evaluated a solution that utilizes QoS, queues and parallel
technologies in a multi-layer Cisco Catalyst Switch to increase NIDPSs detection performance.
Our approach designs a novel QoS architecture to organise and improve throughput-forwardplan
traffic in a layer 3 switch in order to improve NIDPS performance.

Comparison of Compression Algorithms in text data for Data Mining
Text data compression is a process of reducing text size by encrypting it. In our daily lives, we sometimes come to the point where the physical limitations of a text or data sent to work with it need to be addressed more quickly. Ways to create text compression should be adaptive and challenging. Compressing text data without losing the original context is important because it significantly reduces storage and communication costs. In this study, the focus is on different techniques of encoding text files and comparing them in data processing. Some efficient memory encryption programs are analyzed and executed in this work. These include: Shannon Fano coding, Hoffman coding, Hoffman comparative coding, LZW coding and Run-length coding. These analyzes show how these coding techniques work, how much compression for these coding techniques. Writing, the amount of memory required for each technique, a comparison between these techniques is possible to find out which technique is better in which conditions. Experiments have shown that Hoffman's comparative coding shows a higher compression ratio. In addition, the improved RLE encoding suggests a higher performance than the typical example in compressing data in text.

Implementation of New Modified MD5-512 bit Algorithm for Cryptography
In the past few years, there have been significant research advances in the analysis of hash functions and it
was shown that none of the hash algorithm is secure enough for critical purposes whether it is MD5 or SHA-
1.Nowadays scientists have found weaknesses in a number of hash functions, including MD5, SHA and RIPEMD so
the purpose of this paper is combination of some function to reinforce these functions and also increasing hash code

The document proposes a new method for boosting the capacity of web-based steganography by utilizing HTML space codes. It improves upon previous methods by hiding 4 bits per space segment rather than 2 bits, allowing for higher data embedding capacity while maintaining imperceptibility. The method encrypts messages before embedding them in the spaces between text in HTML tags using special space codes. It is evaluated experimentally and shown to have higher capacity than previous approaches while maintaining imperceptibility through minimal changes to file size.
A comparative review on symmetric and asymmetric DNA-based cryptography
Current researchers have focused on DNA-based cryptography, in fact, DNA or deoxyribonucleic acid, has been applied in cryptography for performing computation as well as storing and transmitting information. In the present work, we made use of DNA in cryptographic, i.e. its storing capabilities (superior information density) and parallelism, in order to improve other classical cryptographic algorithms. Data encryption is made possible via DNA sequences. In this paper, two cases utilizing different DNA properties were studied by combining the DNA codes with those conventional cryptography algorithms. The first case concerned on symmetric cryptography that involved DNA coding with OTP (one time pad) algorithms. Asymmetric cryptography was considered in the second case by incorporating the DNA codes in RSA algorithm. The efficiencies of DNA coding in OTP, RSA, and other algorithms were given. As observed, the computational time of RSA algorithm combined with DNA coding was longer. In order to alleviate this problem, data redundancy was reduced by activating the GZIP compressed algorithm. The present experimental results showed that DNA symmetric cryptography worked quite well in both time and size analyses. Nevertheless, it was less efficient than the compressed DNA asymmetric cryptography.

Efficient Association Rule Mining in Heterogeneous Data Base
This document summarizes an algorithm for efficiently mining association rules from heterogeneous databases. The algorithm distributes the database across multiple sites while ensuring privacy. Each site locally mines frequent itemsets using an algorithm like Apriori. The sites then securely combine candidate itemsets and check rule confidence to find globally frequent rules meeting minimum support and confidence thresholds. The algorithm uses commutative encryption and a map-reduce model to parallelize the distributed mining efficiently while limiting data disclosure between sites.
Data Deduplication: Venti and its improvements
This document summarizes the data deduplication system called Venti and improvements over it. Venti identifies duplicate data blocks using cryptographic hashes of block contents. It stores only a single copy of each unique block. The document discusses three key limitations of Venti: hash collisions, fixed-size chunking sensitivity, and access control. It then summarizes approaches taken by other systems to improve on these limitations, such as using multiple hash functions to reduce collisions, variable-length chunking, and stronger authentication and encryption. In conclusion, while Venti was effective at eliminating data duplication, later systems aimed to address its remaining challenges to handle growing archive sizes securely and efficiently.

Classifying confidential data using SVM for efficient cloud query processing
Nowadays, organizations are widely using a cloud database engine from the cloud service
providers. Privacy still is the main concern for these organizations where every organization is strictly
looking forward more secure environment for their own data. Several studies have proposed different types
of encryption methods to protect the data over the cloud. However, the daily transactions represented by
queries for such databases makes encryption is inefficient solution. Therefore, recent studies presented
a mechanism for classifying the data prior to migrate into the cloud. This would reduce the need of
encryption which enhances the efficiency. Yet, most of the classification methods used in the literature
were based on string-based matching approach. Such approach suffers of the exact match of terms where
the partial matching would not be considered. This paper aims to take the advantage of N-gram
representation along with Support Vector Machine classification. A real-time data will used in
the experiment. After conducting the classification, the Advanced Encryption Standard algorithm will be
used to encrypt the confidential data. Results showed that the proposed method outperformed the baseline
encryption method. This emphasizes the usefulness of using the machine learning techniques for
the process of classifying the data based on confidentiality.

The Royal Split Paradigm: Real-Time Data Fragmentation and Distributed Networ...
With data encryption, access control, and monitoring technology, high profile data breaches still
occur. To address this issue, this work focused on securing data at rest and data in motion by
utilizing current distributed network technology in conjunction with a data fragmenting and
defragmenting algorithm. Software prototyping was used to exhaustively test this new paradigm
within the confines of the Defense Technology Experimental Research (DETER) virtual testbed.
The virtual testbed was used to control all aspects within the testing network including: node
population, topology, file size, and number of fragments. In each topology, and for each
population size, different sized files were fragmented, distributed to nodes on the network,
recovered, and defragmented. All of these tests were recorded and documented. The results
produced by this prototype showed, with the max wait time removed, an average wait time of
.0287 s/fragment and by increasing the number of fragments, N, the complexity, X, would
increase as demonstrated in the formula: X = (.00287N!).

Cloud storage (CS) is gaining much popularity nowadays because it offers low-cost and convenient network storage services. In this big data era, the explosive growth in digital data moves the users towards CS to store their massive data. This explosive growth of data causes a lot of storage pressure on CS systems because a large volume of this data is redundant. Data deduplication is a most-effective data reduction technique that identifies and eliminates the redundant data. Dynamic nature of data makes security and ownership of data as a very important issue. Proof-of-ownership schemes are a robust way to check the ownership claimed by any owner. However to protect the privacy of data, many users encrypt it before storing in CS. This method affects the deduplication process because encryption methods have varying characteristics. Convergent encryption (CE) scheme is widely used for secure data deduplication, but it destroys the message equality. Although, DupLESS provides strong privacy by enhancing CE, but it is also found insufficient. The problem with the CE-based scheme is that the user can decrypt the cloud data while he has lost his ownership. This paper addresses the problem of ownership revocation by proposing a secure deduplication scheme for encrypted data. The proposed scheme enhances the security against unauthorized encryption and poison attack on the predicted set of data.

handle data with DHT and load balnce over P2P network
The document discusses load balancing in peer-to-peer (P2P) networks using distributed hash tables (DHTs). It describes how DHTs aim to distribute loads evenly across nodes through decentralization and fault tolerance. The document outlines a framework for a P2P load balancing system using DHTs and discusses how different DHT implementations handle load balancing. It concludes that load balancing in P2P systems is primarily based on DHTs, which aim to distribute requests uniformly across nodes.
Data deduplication and chunking
Data deduplication is a technique to eliminate redundant data and reduce storage needs. It works by identifying identical data chunks using cryptographic hash signatures and storing only one copy of each unique chunk. Chunking refers to dividing files into smaller chunks which are then analyzed to find duplicates. There are different approaches to chunking, including fixed-size, variable content-defined sizes, and frequency-based chunking. Chunk-level deduplication identifies redundancy at a finer granularity than file-level deduplication and is generally more efficient, though it requires an effective chunking algorithm to maximize deduplication benefits.
Secure distributed deduplication systems with improved reliability
The document proposes new distributed deduplication systems with higher reliability for secure cloud storage. Data chunks are distributed across multiple cloud servers using a deterministic secret sharing scheme. This improves reliability over traditional deduplication systems that store only one copy of each file. The systems aim to achieve security requirements of data confidentiality and consistency while limiting overhead.
IRJET- Cross User Bigdata Deduplication
This document summarizes and reviews various techniques for cross-user big data deduplication. It proposes a model that performs deduplication of data for multiple users to achieve uniqueness of textual data uploaded by users while maintaining efficient data access and privacy. The model uses a fixed-size blocking algorithm and hashing algorithm to divide files into blocks, generate hash keys for each block, and perform intra-user and inter-user deduplication checking in two phases to identify and eliminate redundant data across users. It reviews related work that uses techniques like MapReduce, clustering, variable size chunking and metadata to implement parallel and application-driven deduplication.
Enabling efficient multi keyword ranked
This document proposes an efficient multi-keyword ranked search (EMRS) scheme over encrypted mobile cloud data through blind storage. The EMRS enables search users to perform multi-keyword searches over encrypted documents stored on a cloud server and receive ranked search results based on relevance. It utilizes techniques like relevance scoring, secure k-nearest neighbor computation, and blind storage to provide search functionality while preserving security and privacy. The scheme is analyzed to demonstrate that it achieves confidentiality of documents and index, trapdoor privacy, trapdoor unlinkability, and conceals access patterns, addressing key security requirements. Experimental results show the EMRS provides improved efficiency and functionality compared to existing proposals.

This document discusses processing private K-nearest neighbor (KNN) queries over untrusted cloud data. It proposes a framework that uses privacy homomorphism to securely process queries while preserving the privacy of both the data owner and the client submitting queries. The framework divides query processing into node traversal and distance computation steps. It encrypts the data index and uses the cloud to decrypt distances during computation, while preventing any party from accessing the actual query or result distances. The framework allows private querying without revealing sensitive information to the cloud or data owner.
Improving Data Storage Security in Cloud using Hadoop
The rising abuse of information stored on large data centres in cloud emphasizes the need to safe guard the data. Despite adopting strict authentication policies for cloud users data while transferred over to secure channel when reaches data centres is vulnerable to numerous attacks .The most widely adoptable methodology is safeguarding the cloud data is through encryption algorithm. Encryption of large data deployed in cloud is actually a time consuming process. For the secure transmission of information AES encryption has been used which provides most secure way to transfer the sensitive information from sender to the intended receiver. The main purpose of using this technique is to make sensitive information unreadable to all other except the receiver. The data thus compressed enables utilization of storage space in cloud environment. It has been augmented with Hadoop‟s map-reduce paradigm which works in a parallel mode. The experimental results clearly reflect the effectiveness of the methodology to improve the security of data in cloud environment.

Information security via encryption decryption techniques is a very popular research area for many people’s over the years. This paper elaborates the basic concept of the cryptography, specially public and private cryptography. It also contains a review of some popular encryption decryption algorithms. A modified method is also proposed. This method is fast in comparison to the existing methods.

Efficient Association Rule Mining in Heterogeneous Data Base
This document summarizes an algorithm for efficiently mining association rules from heterogeneous databases. The algorithm distributes the database across multiple sites while ensuring privacy. Each site locally mines frequent itemsets using an algorithm like Apriori. The sites then securely combine candidate itemsets and check rule confidence to find globally frequent rules meeting minimum support and confidence thresholds. The algorithm uses commutative encryption and a map-reduce model to parallelize the distributed mining efficiently while limiting data disclosure between sites.
Data Deduplication: Venti and its improvements
This document summarizes the data deduplication system called Venti and improvements over it. Venti identifies duplicate data blocks using cryptographic hashes of block contents. It stores only a single copy of each unique block. The document discusses three key limitations of Venti: hash collisions, fixed-size chunking sensitivity, and access control. It then summarizes approaches taken by other systems to improve on these limitations, such as using multiple hash functions to reduce collisions, variable-length chunking, and stronger authentication and encryption. In conclusion, while Venti was effective at eliminating data duplication, later systems aimed to address its remaining challenges to handle growing archive sizes securely and efficiently.

Classifying confidential data using SVM for efficient cloud query processing
Nowadays, organizations are widely using a cloud database engine from the cloud service
providers. Privacy still is the main concern for these organizations where every organization is strictly
looking forward more secure environment for their own data. Several studies have proposed different types
of encryption methods to protect the data over the cloud. However, the daily transactions represented by
queries for such databases makes encryption is inefficient solution. Therefore, recent studies presented
a mechanism for classifying the data prior to migrate into the cloud. This would reduce the need of
encryption which enhances the efficiency. Yet, most of the classification methods used in the literature
were based on string-based matching approach. Such approach suffers of the exact match of terms where
the partial matching would not be considered. This paper aims to take the advantage of N-gram
representation along with Support Vector Machine classification. A real-time data will used in
the experiment. After conducting the classification, the Advanced Encryption Standard algorithm will be
used to encrypt the confidential data. Results showed that the proposed method outperformed the baseline
encryption method. This emphasizes the usefulness of using the machine learning techniques for
the process of classifying the data based on confidentiality.

The Royal Split Paradigm: Real-Time Data Fragmentation and Distributed Networ...
With data encryption, access control, and monitoring technology, high profile data breaches still
occur. To address this issue, this work focused on securing data at rest and data in motion by
utilizing current distributed network technology in conjunction with a data fragmenting and
defragmenting algorithm. Software prototyping was used to exhaustively test this new paradigm
within the confines of the Defense Technology Experimental Research (DETER) virtual testbed.
The virtual testbed was used to control all aspects within the testing network including: node
population, topology, file size, and number of fragments. In each topology, and for each
population size, different sized files were fragmented, distributed to nodes on the network,
recovered, and defragmented. All of these tests were recorded and documented. The results
produced by this prototype showed, with the max wait time removed, an average wait time of
.0287 s/fragment and by increasing the number of fragments, N, the complexity, X, would
increase as demonstrated in the formula: X = (.00287N!).

Cloud storage (CS) is gaining much popularity nowadays because it offers low-cost and convenient network storage services. In this big data era, the explosive growth in digital data moves the users towards CS to store their massive data. This explosive growth of data causes a lot of storage pressure on CS systems because a large volume of this data is redundant. Data deduplication is a most-effective data reduction technique that identifies and eliminates the redundant data. Dynamic nature of data makes security and ownership of data as a very important issue. Proof-of-ownership schemes are a robust way to check the ownership claimed by any owner. However to protect the privacy of data, many users encrypt it before storing in CS. This method affects the deduplication process because encryption methods have varying characteristics. Convergent encryption (CE) scheme is widely used for secure data deduplication, but it destroys the message equality. Although, DupLESS provides strong privacy by enhancing CE, but it is also found insufficient. The problem with the CE-based scheme is that the user can decrypt the cloud data while he has lost his ownership. This paper addresses the problem of ownership revocation by proposing a secure deduplication scheme for encrypted data. The proposed scheme enhances the security against unauthorized encryption and poison attack on the predicted set of data.

handle data with DHT and load balnce over P2P network
The document discusses load balancing in peer-to-peer (P2P) networks using distributed hash tables (DHTs). It describes how DHTs aim to distribute loads evenly across nodes through decentralization and fault tolerance. The document outlines a framework for a P2P load balancing system using DHTs and discusses how different DHT implementations handle load balancing. It concludes that load balancing in P2P systems is primarily based on DHTs, which aim to distribute requests uniformly across nodes.
Data deduplication and chunking
Data deduplication is a technique to eliminate redundant data and reduce storage needs. It works by identifying identical data chunks using cryptographic hash signatures and storing only one copy of each unique chunk. Chunking refers to dividing files into smaller chunks which are then analyzed to find duplicates. There are different approaches to chunking, including fixed-size, variable content-defined sizes, and frequency-based chunking. Chunk-level deduplication identifies redundancy at a finer granularity than file-level deduplication and is generally more efficient, though it requires an effective chunking algorithm to maximize deduplication benefits.
Secure distributed deduplication systems with improved reliability
The document proposes new distributed deduplication systems with higher reliability for secure cloud storage. Data chunks are distributed across multiple cloud servers using a deterministic secret sharing scheme. This improves reliability over traditional deduplication systems that store only one copy of each file. The systems aim to achieve security requirements of data confidentiality and consistency while limiting overhead.
IRJET- Cross User Bigdata Deduplication
This document summarizes and reviews various techniques for cross-user big data deduplication. It proposes a model that performs deduplication of data for multiple users to achieve uniqueness of textual data uploaded by users while maintaining efficient data access and privacy. The model uses a fixed-size blocking algorithm and hashing algorithm to divide files into blocks, generate hash keys for each block, and perform intra-user and inter-user deduplication checking in two phases to identify and eliminate redundant data across users. It reviews related work that uses techniques like MapReduce, clustering, variable size chunking and metadata to implement parallel and application-driven deduplication.
Enabling efficient multi keyword ranked
This document proposes an efficient multi-keyword ranked search (EMRS) scheme over encrypted mobile cloud data through blind storage. The EMRS enables search users to perform multi-keyword searches over encrypted documents stored on a cloud server and receive ranked search results based on relevance. It utilizes techniques like relevance scoring, secure k-nearest neighbor computation, and blind storage to provide search functionality while preserving security and privacy. The scheme is analyzed to demonstrate that it achieves confidentiality of documents and index, trapdoor privacy, trapdoor unlinkability, and conceals access patterns, addressing key security requirements. Experimental results show the EMRS provides improved efficiency and functionality compared to existing proposals.

This document discusses processing private K-nearest neighbor (KNN) queries over untrusted cloud data. It proposes a framework that uses privacy homomorphism to securely process queries while preserving the privacy of both the data owner and the client submitting queries. The framework divides query processing into node traversal and distance computation steps. It encrypts the data index and uses the cloud to decrypt distances during computation, while preventing any party from accessing the actual query or result distances. The framework allows private querying without revealing sensitive information to the cloud or data owner.

Improving Data Storage Security in Cloud using Hadoop
The rising abuse of information stored on large data centres in cloud emphasizes the need to safe guard the data. Despite adopting strict authentication policies for cloud users data while transferred over to secure channel when reaches data centres is vulnerable to numerous attacks .The most widely adoptable methodology is safeguarding the cloud data is through encryption algorithm. Encryption of large data deployed in cloud is actually a time consuming process. For the secure transmission of information AES encryption has been used which provides most secure way to transfer the sensitive information from sender to the intended receiver. The main purpose of using this technique is to make sensitive information unreadable to all other except the receiver. The data thus compressed enables utilization of storage space in cloud environment. It has been augmented with Hadoop‟s map-reduce paradigm which works in a parallel mode. The experimental results clearly reflect the effectiveness of the methodology to improve the security of data in cloud environment.

Cloud security: literature survey
Today, the growth of digitalization has made the ease for livelihood for all the organizations. Cloud computing the storage provider for all the computer resources has made it easy for accessing the data from anywhere anytime. But at the same time the security for cloud data storage is the major drawback which is provided by various cryptographic algorithms. These algorithms convert the data into unreadable format, known as cipher text, Rivest, Shamir and Adleman (RSA) one of the most popularly used asymmetric algorithm. This paper gives detailed review about such different cryptographic algorithms used for the cloud data security. The comparison study is also made for the size of data and to analyze the encryption time and decryption time, which concludes that to enhance the cloud data security some addon techniques are to be used along with these cryptographic algorithms. To increase the security level and to increase the transmission speed of plaintext, integrated method will be proposed by encoding the plaintext to intermediate plaintext and then intermediate plaintext will be compressed using any one of the compression techniques to increase the compression ratio, lastly the compressed file is encrypted to further enhance the security level.

IRJET - A Novel Approach Implementing Deduplication using Message Locked Encr...
This document proposes a novel approach to implementing data deduplication on the cloud using message locked encryption. It aims to overcome limitations of existing deduplication techniques like convergent encryption by using erasure code technology, encryption algorithms like DES and MD5 hashing, and tokenization to securely store and protect client data on the cloud. The proposed system gives clients proof of ownership of their data by allowing them to choose who can access their files and see any changes made over time. The system architecture involves a client uploading encrypted data to the cloud, and recipients selected by the client being able to access and retrieve encrypted pieces of the data.
Improved deduplication with keys and chunks in HDFS storage providers
The document proposes a new deduplication scheme for HDFS storage providers that improves reliability. It uses MD5 hashing to generate unique tags for files and blocks, and stores the tags in a metadata file. Ownership verification is done during upload/download by checking these tags. Encrypted data is distributed across block servers for reliability. Convergent keys derived from hashes encrypt the data blocks using 3DES. This ensures security while allowing deduplication. The scheme achieves both file-level and block-level deduplication and uses distributed key servers for reliable key management at large scale.

This document summarizes a study that evaluates the performance of four symmetric key cryptography algorithms: DES, 3DES, Blowfish, and AES. The study considers criteria like file size, file type, encryption and decryption time, and block size. It finds that Blowfish has the best performance, encrypting and decrypting data faster than the other algorithms. AES also performs well, while 3DES has the lowest performance due to its longer key length. The document reviews related literature comparing the performance of symmetric key cryptography algorithms and techniques that combine cryptography with steganography for enhanced security.

A.为什么留学生需要操作留信认证?
留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。只硕大的蛇皮袋手里拎着长铁钩正站在门口朝黑色的屋内张望不好坏人小偷山娃一怔却也灵机一动立马仰起头双手拢在嘴边朝楼上大喊：“爸爸爸——有人找——那人一听朝山娃尴尬地笑笑悻悻地走了山娃立马“嘭的一声将铁门锁死心却咚咚地乱跳当山娃跟父亲说起这事时父亲很吃惊抚摸着山娃的头说还好醒得及时要不家早被人掏空了到时连电视也没得看啰不过父亲还是夸山娃能临危不乱随机应变有胆有谋山娃笑笑说那都是书上学的看童话和小说时多
The Building Blocks of QuestDB, a Time Series Database
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed.

End-to-end pipeline agility - Berlin Buzzwords 2024
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

Global Situational Awareness of A.I. and where its headed
You can see the future first in San Francisco.
Over the past year, the talk of the town has shifted from $10 billion compute clusters to $100 billion clusters to trillion-dollar clusters. Every six months another zero is added to the boardroom plans. Behind the scenes, there’s a fierce scramble to secure every power contract still available for the rest of the decade, every voltage transformer that can possibly be procured. American big business is gearing up to pour trillions of dollars into a long-unseen mobilization of American industrial might. By the end of the decade, American electricity production will have grown tens of percent; from the shale fields of Pennsylvania to the solar farms of Nevada, hundreds of millions of GPUs will hum.
The AGI race has begun. We are building machines that can think and reason. By 2025/26, these machines will outpace college graduates. By the end of the decade, they will be smarter than you or I; we will have superintelligence, in the true sense of the word. Along the way, national security forces not seen in half a century will be un-leashed, and before long, The Project will be on. If we’re lucky, we’ll be in an all-out race with the CCP; if we’re unlucky, an all-out war.
Everyone is now talking about AI, but few have the faintest glimmer of what is about to hit them. Nvidia analysts still think 2024 might be close to the peak. Mainstream pundits are stuck on the wilful blindness of “it’s just predicting the next word”. They see only hype and business-as-usual; at most they entertain another internet-scale technological change.
Before long, the world will wake up. But right now, there are perhaps a few hundred people, most of them in San Francisco and the AI labs, that have situational awareness. Through whatever peculiar forces of fate, I have found myself amongst them. A few years ago, these people were derided as crazy—but they trusted the trendlines, which allowed them to correctly predict the AI advances of the past few years. Whether these people are also right about the next few years remains to be seen. But these are very smart people—the smartest people I have ever met—and they are the ones building this technology. Perhaps they will be an odd footnote in history, or perhaps they will go down in history like Szilard and Oppenheimer and Teller. If they are seeing the future even close to correctly, we are in for a wild ride.
Let me tell you what we see.

- 1. A DETAILED SURVEY ON TEXT DATA SECURITY AND COMPRESSION TECHNIQUES USING HUFFMAN CODING COMPRESSION AUTHOR ANU MATTATHOLI MPhil COMPUTER SCIENCE(FT) NASC CO-AUTHOR DR.N. KAVITHA(HOD) DEPT. OF CS NASC COIMBATORE
- 2. OBJECTIVE Data Security and Compression is much helpful for effective data management. Compression process saves storage space and makes easy transmission. For text data compression, the best technique ever used is Huffman Coding. It is an optimal technique used in both lossy and lossless data.
- 3. WHAT THIS PAPER IS ABOUT?? This paper gives you a comprehensive analysis on existing data compression techniques. The analysis focus mainly on Huffman coding, and also provides direction to solve problems of such systems.
- 4. Index Terms Data Compression Data Security Huffman Coding Lossless data Compression
- 5. Introduction Due to internet applications, digital data flow became very huge and occupied more storage space. So its difficult to handle data because of this huge size. How this should be overcome???
- 6. Continuation… Using Data Compression. This will be the best way to achieve high security and can reduce storage space with less transaction time.
- 7. Continuation… On which file format data level security can be performed?? In text , image, audio, video etc…. In this paper ,text data security and compression techniques are analyzed.
- 8. Process flow involved…… Block Diagram Source Data Multilevel Security Compression Decompression Compressed Data
- 9. Continuation… Data Compression Lossy Compression (Most effective) Lossless Compression (Used in this paper)
- 10. Techniques Used for Data Compression Both takes stream of symbols and transform into codes. The stream code size will determine the effectiveness of compression. If code size is less than original the compression is effective. Two step process Modeling Coding
- 11. Continuation… Lossless data compression Statistical Reads single symbol using probability of character appearance Dictionary based Uses a single code to replace string of symbols. Coding problem is reduced.
- 12. Huffman Coding Really popular method for effective data compression. Types of Huffman Coding : Adaptive Huffman Coding, Shannon entropy, Run-length encoding and so on…. Uses prefix code generation process. Creates a binary tree and generates different symbols with probability.
- 13. Continuation…. An unique prefix code is assigned to each symbol. Static Huffman Coding reads data twice. One for initially calculating frequency and next for reading the content again. In Dynamic Huffman coding, it starts with empty tree and modifies. Compression and Decompression change the tree in a same way that used for compression.
- 14. Boon while Using Huffman Coding Paper[5],Distributed Data Aggregation Service have been implemented using Adaptive Huffman Coding using the authentication protocol Kerberos. It increases the security and ensures that authorized client is able to access distributed database.
- 15. Continuation… • Paper[6],Huffman coding improves data security and reduces the size of high dimensional data array. • Paper[7], Lossless methods of Huffman Coding technique has achieved fast data compression and converts into confidential data array. • Paper[8],Bit-stuffing and Huffman coding can provide high level security and performance on compression processes. • It reduces transmission time and bandwidth utilization.
- 16. Curse while using Huffman Coding Difficult to execute at some while… Sometimes the binary tree implementation shouldn’t give accurate result.
- 17. Conclusion • The analysis of encoding techniques and tools for compression is discussed. • This paper specifically concentrated on Huffman Coding related works and its drawbacks. • Survey gives technique for text data. • Huffman Coding is popular, but execution issues arises. • This paper gives idea about such issues in brief. • From this analysis, an optimal solution can be found.
