A Codon Frequency Obfuscation Heuristic for Raw Genomic Data PrivacyKato Mivule
Genomic data provides clinical researchers with vast opportunities to study various patient ailments. Yet the same data contains revealing information, some of which a patient might want to remain concealed. The question then arises: how can an entity transact in full DNA data while concealing certain sensitive pieces of information in the genome sequence, and maintain DNA data utility? As a response to this question, we propose a codon frequency obfuscation heuristic, in which a redistribution of codon frequency values with highly expressed genes is done in the same amino acid group, generating an obfuscated DNA sequence. Our preliminary results show that it might be possible to publish an obfuscated DNA sequence with a desired level of similarity (utility) to the original DNA sequence. http://arxiv.org/abs/1405.5410

Framework for reversible data hiding using cost-effective encoding system for...IJECEIAES
Importance’s of reversible data hiding practices are always higher in contrast to any conventional data hiding schemes owing to its capability to generate distortion free cover media. Review of existing approaches on reversible data hiding approaches shows variable scheme mainly focusing on the embedding mechanism; however, such schemes could be furthermore improved using encoding scheme for optimal embedding performance. Therefore, the proposed manuscript discusses about a cost-effective scheme where a novel encoding scheme has been used with larger block sizes which reduces the dependencies over larger number of blocks. Further a gradient- based image registration technique is applied to ensure higher quality of the reconstructed signal over the decoding end. The study outcome shows that proposed data hiding technique is proven better than existing data hiding scheme with good balance between security and restored signal quality upon extraction of data.

A Survey Paper on an Integrated Approach for Privacy Preserving In High Dimen...IJSRD
Data mining is a technique which is used for extraction of knowledge and information from large amount of data collected by hospitals, government and individuals. The term data mining is also referred as knowledge mining from databases. The major challenge in data mining is ensuring security and privacy of data in databases, because data sharing is common at organizational level. The data in databases comes from a number of sources like – medical, financial, library, marketing, shopping record etc so it is foremost task for anyone to keep secure that data. The objective is to achieve fully privacy preserved data without affecting the data utility in databases. i.e. how data is used or transferred between organizations so that data integrity remains in database but sensitive and confidential data is preserved. This paper presents a brief study about different PPDM techniques like- Randomization, perturbation, Slicing, summarization etc. by use of which the data privacy can be preserved. The technique for which the best computational and theoretical outcome is achieved is chosen for privacy preserving in high dimensional data.
Most of the time, when you hear about Artificial Intelligence (AI), people talk about new algorithms or even the computation power needed to train them. But Data is one of the most important factors in AI.
Big Data Security and Privacy - Presentation to AFCEA Cyber Symposium 2014kevintsmith
In our era of “Big Data”, organizations are collecting, analyzing, and making decisions based on analysis of massive amounts of data sets from various sources, and security in this process is becoming increasingly more important. With regulations like HIPAA and other privacy protection laws, securing access and determining releasability of data sets is critical. Organizations using Big Data Analytics solutions face challenges, as most of today’s solutions were not designed with security in mind. This presentation focuses on challenges, use cases, and practical real-world solutions related to securing and preserving privacy in Big Data Analytics solutions, addressing authorization, differential privacy, and more.

Security and privacy methods are used to protect the data values. Private data values are secured with
confidentiality and integrity methods. Privacy model hides the individual identity over the public data values.
Sensitive attributes are protected using anonymity methods. Two or more parties have their own private data under
the distributed environment. The parties can collaborate to calculate any function on the union of their data. Secure
Multiparty Computation (SMC) protocols are used in privacy preserving data mining in distributed environments.
Association rule mining techniques are used to fetch frequent patterns.Apriori algorithm is used to mine association
rules in databases. Homogeneous databases share the same schema but hold information on different entities.
Horizontal partition refers the collection of homogeneous databases that are maintained in different parties. Fast
Distributed Mining (FDM) algorithm is an unsecured distributed version of the Apriori algorithm. Kantarcioglu
and Clifton protocol is used for secure mining of association rules in horizontally distributed databases. Unifying
lists of locally Frequent Itemsets Kantarcioglu and Clifton (UniFI-KC) protocol is used for the rule mining process
in partitioned database environment. UniFI-KC protocol is enhanced in two methods for security enhancement.
Secure computation of threshold function algorithm is used to compute the union of private subsets in each of the
interacting players. Set inclusion computation algorithm is used to test the inclusion of an element held by one
player in a subset held by another.The system is improved to support secure rule mining under vertical partitioned
database environment. The subgroup discovery process is adapted for partitioned database environment. The
system can be improved to support generalized association rule mining process. The system is enhanced to control
security leakages in the rule mining process.

In this era, there are need to secure data in distributed database system. For collaborative data
publishing some anonymization techniques are available such as generalization and bucketization. We consider
the attack can call as “insider attack” by colluding data providers who may use their own records to infer
others records. To protect our database from these types of attacks we used slicing technique for anonymization,
as above techniques are not suitable for high dimensional data. It cause loss of data and also they need clear
separation of quasi identifier and sensitive database. We consider this threat and make several contributions.
First, we introduce a notion of data privacy and used slicing technique which shows that anonymized data
satisfies privacy and security of data which classifies data vertically and horizontally. Second, we present
verification algorithms which prove the security against number of providers of data and insure high utility and
data privacy of anonymized data with efficiency. For experimental result we use the hospital patient datasets
and suggest that our slicing approach achieves better or comparable utility and efficiency than baseline
algorithms while satisfying data security. Our experiment successfully demonstrates the difference between
computation time of encryption algorithm which is used to secure data and our system.
Performance Analysis of Hybrid Approach for Privacy Preserving in Data Miningidescitation
Now-a day’s data sharing between two organizations
is common in many application areas like business planning
or marketing. When data are to be shared between parties,
there could be some sensitive data which should not be
disclosed to the other parties. Also medical records are more
sensitive so, privacy protection is taken more seriously. As
required by the Health Insurance Portability and
Accountability Act (HIPAA), it is necessary to protect the
privacy of patients and ensure the security of the medical
data. To address this problem, released datasets must be
modified unavoidably. We propose a method called Hybrid
approach for privacy preserving and implemented it. First we
randomized the original data. Then we have applied
generalization on randomized or modified data. This
technique protect private data with better accuracy, also it can
reconstruct original data and provide data with no information
loss, makes usability of data.

A Study of Usability-aware Network Trace Anonymization Kato Mivule
The publication and sharing of network trace data is a critical to the advancement of collaborative research among various entities, both in government, private sector, and academia. However, due to the sensitive and confidential nature of the data involved, entities have to employ various anonymization techniques to meet legal requirements in compliance with confidentiality policies. Nevertheless, the very composition of network trace data makes it a challenge when applying anonymization techniques. On the other hand, basic application of microdata anonymization techniques on network traces is problematic and does not deliver the necessary data usability. Therefore, as a contribution, we point out some of the ongoing challenges in the network trace anonymization. We then suggest usability-aware anonymization heuristics by employing microdata privacy techniques while giving consideration to usability of the anonymized data. Our preliminary results show that with trade-offs, it might be possible to generate anonymized network traces with enhanced usability, on a case-by-case basis using micro-data anonymization techniques.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

3. Utilizing Noise Addition for Data Privacy, an Overview
Introduction
•The internet is a medium for both the production and consumption of data.
•Cyber-crime involving the theft of private data is growing.
•Privacy, security, and compliancy to privacy laws must be taken into account.
•In this paper:
• We give a foundational outlook on noise addition for data privacy.
• We look at statistical consideration for noise addition.
• We look at the current state of the art in the field.
• We outline future areas of research in data privacy.
4. Utilizing Noise Addition for Data Privacy, an Overview
Introduction
Data De-identification:
•Large entities such as the Census Bureau release transformed data to the public
after omitting sensitive information such as personal identifying information
(PII).
•Researchers have shown that publicly released datasets in conjunction with
supplemental data, adversaries are able to reconstruct sensitive information .
•Therefore while data de-identification is essential, it should be taken as an
initial step; other methods such as noise addition should strongly be considered.
5. Utilizing Noise Addition for Data Privacy, an Overview
Introduction
Figure 1: Generalized Data Privacy with Noise Addition
• A generalized data privacy procedure would involve both data de-
identification and perturbation as shown in Figure 1.
6. Utilizing Noise Addition for Data Privacy, an Overview
Background
•Data Privacy and Confidentiality is the protection of an individual against
illegitimate information exposure.
•Data Security is concerned with legitimate accessibility of data .
•Data de-identification process also referred to as data anonymization, data
sanitization, and statistical disclosure control (SDC),
• is a process in which PII attributes are excluded or denatured to such
an extent that when the data is made public, a person's identity, or an
entity's sensitive data, cannot be reconstructed .
7. Utilizing Noise Addition for Data Privacy, an Overview
Background
•Statistical disclosure control methods are classified as non-perturbative and
perturbative:
• Non- pertubative: a procedure in which original data is not
denatured.
• Pertubative: original data is denatured before publication to provide
confidentiality .
•Inference and reconstruction attacks:
• Isolated pieces of data are used to infer a supposition about a person
or an entity.
8. Utilizing Noise Addition for Data Privacy, an Overview
Background
•Data utility verses privacy is how useful a published dataset is to the consumer
of that publicized dataset.
• Privatized datasets loose utility with PII is removal and noise addition
• Therefore a balance between privacy and utility needs is always
sought.
•NP-hard task: Data privacy scholars have noted that achieving optimal data
privacy while not shrinking data utility is an ongoing NP-hard task.
•Statistical databases are non-changing data sets often published in aggregated
format
9. Utilizing Noise Addition for Data Privacy, an Overview

techniques in data mining, providing advantages and disadvantages of various data
privacy procedures.
10. Utilizing Noise Addition for Data Privacy, an Overview
Noise Addition
•Noise addition works by adding or multiplying a stochastic or randomized
number to confidential quantitative attributes.
•The stochastic value is chosen from a normal distribution with zero mean and a
diminutive standard deviation .

Noise Addition: Differential Privacy
Figure 2: A general Differential Privacy satisfying procedure
General steps for differential privacy shown in Figure 2:
•Run query on database
•Calculate the most influential observation
•Calculate the Laplace noise distribution
•Add Laplace noise distribution to the query results
•Publish perturbed query results.
28. Utilizing Noise Addition for Data Privacy, an Overview
Illustration
•We created a data set of 10 records for illustrative purposes:
• The original data set contained PII
• We de-identified the original data set
• We applied additive noise to the numerical attributes
• We then plotted the results in a graph, comparing the statistical
properties of the original and perturbed data.

Steps for De-identification and Noise Addition
1. For all values of the data set to be published,
• Do data de-identification
• Find PII
• Remove PII
• For remaining data void of PII to be published,
1. Find quantitative attributes in the data set
• Apply additive noise to the quantitative data values
• Publish data set

• Correlation is a strong positive, it shows a relationship between the two data sets,
increasing and decreasing together.
34. Utilizing Noise Addition for Data Privacy, an Overview
Conclusion
•We looked at latest related work in the field, pointing to the problem of privacy
needs verses data utility.
•We have taken an overview of noise addition techniques for data privacy.
•We also took a look the statistical considerations when utilizing noise addition.
•We provided an illustrative example showing that de-identification of data
when done in concert with noise addition would add more to the privacy of
published data sets while maintaining the statistical properties of the original
data set.
35. Utilizing Noise Addition for Data Privacy, an Overview
Conclusion
•Generating perturbed data sets that are statistically close to the original data sets is still
a challenge.
•Noise generation certainly affects the level of perturbation on the published data set.
•Techniques such as differential privacy provide hope for achieving greater
confidentiality, however, achieving optimal data privacy while not shrinking data utility is
still a challenge.
•Therefore more research needs to be done on how optimal privacy could be achieved
without degrading data utility.
•Another area of research is how noise addition techniques could be optimally applied in
the cloud and mobile computing areas.
