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.
Big data contains valuable information— some of it sensitive customer data—that can be a honeypot for internal and external attackers. Given the risk involved, organizations must proactively enhance defenses and prevent data breaches. The four steps outlined in this deck, help organizations to develop a holistic approach to data security and privacy.

The REAL Impact of Big Data on PrivacyClaudiu Popa
The awesome promise of Big Data is tempered by the need to protect personal information. Data scientists must expertly navigate the legislative waters and acquire the skills to protect privacy and security. This talk provides enterprise leaders with answers and suggests questions to ask when the time comes to consider the vast opportunities offered by big data.
Big Data is the "next" Bg Technology and Business and Hadoop is one of the important framework of Big Data. Hadoop is currently used by Yahoo, EBay and 100s of organisations.
As the Big Data use cases will grow, security of Big Data technologies, solutions and applications will become extremely important. In this presentation, I have described top 5 key security challenges related to developing Big Data solutions and applications.
Cyber Summit 2016: Privacy Issues in Big Data Sharing and ReuseCybera Inc.
Although there is no well-established definition of big data, its main characteristic is its sheer volume. Large volumes of data are generated by people (e.g., via social media) and by technology, including sensors (e.g., cameras, microphones), trackers (e.g., RFID tags, web surfing behavior) and other devices (e.g., mobile phones, wearables for self-surveillance/quantified self), whether or not they are connected to the Internet of Things. However, the large volumes of data needed to capitalize on the benefits of big data can to some extent also be established by the reuse of existing data, a source that is sometimes overlooked.
Data can be reused for purposes similar to that for which it was initially collected, but also beyond these purposes. Similarly, data can be reused in its original context, but also beyond this context. However, such repurposing and recontextualizing of data may lead to privacy issues. For instance, data reuse may lead to issues regarding informed consent and informational self-determination. When the data is used for profiling and other types of predictive analytics, also issues regarding stigmatization and discrimination may arise. This presentation by Bart Custers, Head of Research, eLaw – Center for Law and Digital Technologies at Leiden University, The Netherlands, focuses on the privacy issues of big data sharing and reuse and how these issues could be addressed.
Several anonymization techniques, such as generalization and bucketization, have been designed for privacy preserving microdata publishing. Recent work has shown that generalization loses considerable amount of information, especially for high-dimensional data. Bucketization, on the other hand, does not prevent membership disclosure and does not apply for data that do not have a clear separation between quasi-identifying attributes and sensitive attributes. In this paper, we present a novel technique called slicing, which partitions the data both horizontally and vertically. We show that slicing preserves better data utility than generalization and can be used for membership disclosure protection. Another important advantage of slicing is that it can handle high-dimensional data. We show how slicing can be used for attribute disclosure protection and develop an efficient algorithm for computing the sliced data that obey the ℓ-diversity requirement. Our workload experiments confirm that slicing preserves better utility than generalization and is more effective than bucketization in workloads involving the sensitive attribute. Our experiments also demonstrate that slicing can be used to prevent membership disclosure.

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.

response techniques to conduct the data mining computation.
Specially, we present a method to build decision tree
classifiers from the disguised data. We conduct experiments
to compare the accuracy ofou r decision tree with the one
built from the original undisguised data. Our results show
that although the data are disguised, our method can still
achieve fairly high accuracy. We also show how the parameter

Recent controversies such as Apple vs FBI have highlighted that often strong security is a prerequisite for privacy, and that upholding privacy can ensure stronger security is built into software. Can the argument still be made that security must be sacrificed in place of privacy? How much are security and privacy inherently linked?

Comments to FTC on Mobile Data PrivacyMicah Altman
FTC has been hosting a series of seminars on consumer privacy, on which it has requested comments. The most recent seminar explored privacy issues related to mobile device tracking. As the seminar summary points out ...
In most cases, this tracking is invisible to consumers and occurs with no consumer interaction. As a result, the use of these technologies raises a number of potential privacy concerns and questions.
The presentations raised an interesting and important combination of questions about how to promote business and economic innovation while protecting individual privacy. I have submitted a comment on these changes with some proposed recommendations.
To summarize (quoting from the submitted the comment):
Knowledge of an individual’s location history and associations with others has the potential to be used in a wide variety of harmful ways. ... [Furthermore], since all physical activity has a unique spatial and temporal context, location history provides a linchpin for integrating multiple sources of data that may describe an individual. Moreover, locational traces are difficult or impossible to render non-identifiable using traditional masking methods.
Running Head: DATA BREACH 1
DATA BREACH 9
Data Breach Research Proposal
Introduction
In the present world, there has been a series of technological advancements especially in this era of digital migration where everybody is using technology. However, a lot of people do not realize that there are problems that arise as technological changes continue happening. One of the biggest challenge faced in the technological environment is data breaching. This refers to incidences where an individual’s private and confidential information is accessed by unauthorized individuals. Due to diverse lack of technological knowhow, a lot of people and organizations have become victims as occurrences of these data breaches rise each day. In the last two years at least 258,000 organizations has fallen as an estimate of about 3.9 million individuals from different parts of the world has been robbed as a result of data breaches (Ayyagari, 2012).
Clearly, the victim figure above emphasizes the need to come up with a solution to the data breaches more than ever before. The motivation behind carrying out the author’s my proposed research is the rapid changes in the world of technology thatwhich does not match the rate at which a big population adjusts along with the technological changes. This makes them vulnerable to more and more data breaches every day if something is not done. I believe that creating awareness concerning how to be data secure will greatly impact the world positively through reducing the data breaches occurrences.
In my research, I look forward to investigating a number of issues as far as data breaches are concerned. The issues include:
· Causes of data breaches.
· How the data breaches are done.
·
Solution
s to data breaches.
Importance of the proposed research.
With the continual technological advancements, I believe that if a large population of people as well as organizations that make use of technology to store their confidential data get to know all about these issues as well as how to combat data breaches, then the world would be a peaceful place to live in. it will also give room for further technological advancements as the more data secure people will be more willing to embrace the changes.

Causes of data breaches
One of the causes of data breaches is cyber-attacks. This has been the leading data security threat over the last two years. This refers to a situation whereby an individual- cybercriminal- accesses an organization’s data and uses it for malicious gains whether for fun, for financial gains or even for undercover activities such as spying.

Big Data & Privacy -- Response to White House OSTPMicah Altman
Big data has huge implications for privacy, as summarized in our commentary below:
Both the government and third parties have the potential to collect extensive (sometimes exhaustive), fine grained, continuous, and identifiable records of a person’s location, movement history, associations and interactions with others, behavior, speech, communications, physical and medical conditions, commercial transactions, etc. Such “big data” has the ability to be used in a wide variety of ways, both positive and negative. Examples of potential applications include improving government and organizational transparency and accountability, advancing research and scientific knowledge, enabling businesses to better serve their customers, allowing systematic commercial and non-commercial manipulation, fostering pervasive discrimination, and surveilling public and private spheres.
On January 23, 2014, President Obama asked John Podesta to develop in 90 days, a 'comprehensive review' on big data and privacy.
This lead to a series of workshop on big data and technology at MIT, and on social cultural & ethical dimensions at NYU, with a third planned to discuss legal issues at Berkeley. A number of colleagues from our Privacy Tools for Research project and from the BigData@CSAIL projects have contributed to these workshops and raised many thoughtful issues (and the workshop sessions are online and well worth watching).
My colleagues at the Berkman Center, David O'Brien, Alexandra Woods, Salil Vadhan and I have submitted responses to these questions that outline a broad, comprehensive, and systematic framework for analyzing these types of questions and taxonomize a variety of modern technological, statistical, and cryptographic approaches to simultaneously providing privacy and utility. This comment is made on behalf of the Privacy Tools for Research Project, of which we are a part, and has benefitted from extensive commentary by the other project collaborators.

YOURPRIVACYPROTECTOR: A RECOMMENDER SYSTEM FOR PRIVACY SETTINGS IN SOCIAL NET...ijsptm
Ensuring privacy of users of social networks is probably an unsolvable conundrum. At the same time, an informed use of the existing privacy options by the social network participants may alleviate - or even prevent - some of the more drastic privacy-averse incidents. Unfortunately, recent surveys show that an average user is either not aware of these options or does not use them, probably due to their perceived complexity. It is therefore reasonable to believe that tools assisting users with two tasks: 1) understanding their social net behaviour in terms of their privacy settings and broad privacy categories, and 2)recommending reasonable privacy options, will be a valuable tool for everyday privacy practice in a social
network context. This paper presents YourPrivacyProtector, a recommender system that shows how simple machine learning techniques may provide useful assistance in these two tasks to Facebook users. We support our claim with empirical results of application of YourPrivacyProtector to two groups of Facebook
users.
De-anonymizing, Preserving and Democratizing Data Privacy and OwnershipIIIT Hyderabad
The fourth industrial revolution warrants a rapid change to technology, industries, and societal patterns and processes in the 21st century due to increasing interconnectivity and intelligent automation. It brings a dire necessity for data collection at a large scale. The organizations responsible for shepherding the technology to the next level rely on data-hungry algorithms developed due to the advancements in machine learning and deep learning in the last decade. Often, the collected data include personally identifiable information (PII) and pseudo identifiers like age, gender, zip codes, and non-PII attributes. Due to the inclusion of PII attributes, data protection and clearly defining its ownership has become paramount. Despite having several compliances in place like the Health Insurance Portability and Accountability Act (HIPAA) and the National Data Health Mission (NDHM) for healthcare, or the more comprehensive General Data Protection Regulation (GDPR), we witness wrongful disclosure, theft and misuse of data by the organizations that are supposed to be the torchbearers into the new era of technology. Apart from external attacks and breaches, many organizations tend to find workarounds and not follow the data privacy standards governed by laws across the globe. The malpractices like selling data to third parties, using weaker anonymizations, and claiming ownership of data often lead to the loss of sensitive information that directly impacts the people whose data is collected and mishandled in the name of providing services.
Researchers who tried to find a solution to the data misuse problem developed anonymization techniques. However, these techniques like k-anonymity, l-diversity, t-closeness, etc., are proven to be weak and vulnerable by privacy researchers. They have applied cross-linking techniques to de-anonymize i) patients using electronic health records and other public records, ii) American query logs to conclude that 87% of the American population can be uniquely identified by knowing pseudo identifiers like age, gender, and zip codes. As part of our research, we present a cross-linking attack to identify personal identifiable information (PII), including address, family details, voter ID information with just the Twitter username, and publicly available electoral rolls. We further show how academic institutions employ weaker anonymizations to release students’ information, making them vulnerable to cross-linking attacks.
Several anonymized data releases failed due to cross-linking vulnerabilities it carries. We will now discuss differential privacy and how it curbs the limitations of anonymization algorithms. Differential privacy (DP) is a system for publicly sharing information about a dataset by describing the patterns of groups within the dataset while withholding information about individuals. Unlike anonymization, where we reveal the actual individual samples, DP adds noise in a manner such that individual data samples

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

NATIONAL SECURITY
Civil liberty involves everything from pro0tecting
the rights of individuals, be they human, civil or
privacy rights. Gathering information about people,
mining data about them, surveillance on personal
conversations may result in violation of their rights
to privacy.
The main concern is whether to gather information
and prosecute when violation on privacy occurs or
wait until the national disasters occurs to gather
data.
Among the questions that arise include
Is it worth sacrificing privacy to ensure some level of national security
assuming the information is not misused?
Should national security be placed first and then prosecute those who
violate privacy if its not possible to safeguard this private
information? By: https://www.essaypeer.com

NATIONAL SECURITY
Since national security is very important to most nations
in view of the terrorism activity the world over, one of
the way to ensure privacy of personal information is
through sensitive data mining.
Here, data mining is allowed but under enhanced privacy

Sensitive data mining involves determining, in advance
those patterns are private and which are public since

7. SOLVING THE INFERENCE
PROBLEM
Bhavani Thuraisingham (2002) proposes the following
measures to deal with the inference problem in data
mining:
• Build an inference controller that detect possible inference problems by a user and
restricting the use of those patterns
• The other strategy would be to classify the information such that the user would not be
confident in the results and will therefore find the inferences made useless.
• Lastly, the person holding the data can test the data to see if any inferences can be made
using the data. However, this approach is limited because on cannot predict all the
inferences that could be made from the data or the combinnation of tools that will be
used in data mining to get these inferences.

Editor's Notes
I have been asked to select an article relating to data mining, predictive analytics and discovery informatics and describe the main concepts presented in the paper with a view of outlining the contributions that the paper or article has contributed to the field and I shall do that. The paper I choose is “Data Mining, National Security, Privacy and Civil Liberties “. The paper addresses the threats that data mining poses to privacy due to the inference problem and the how to handle the inference problem.
The figure above shows the inference problem in data mining. Inference Is the process of posing queries to a database to get unauthorized information from the innocent responses received from authorized data. Databases are meant to provide access to group data while protecting the confidentiality of personal data. However, a skilled data miner can obtain from these databases information about individuals by correlating the different statistics given in a data base (Farkas and 2002 Jajodia).
Since data mining is a threat to privacy, the challenge would be to protect the privacy of personal information, considering the social and legal precautions in place, and without undermining the ability of data mining to provide trends and timely information to users.
The use of data mining brings with it serious questions on the privacy of personal information.
Privacy enhanced data mining seeks to make available all the benefits that accrue due to the use of data mining in national security issues but at the same time enhance personal information
The article shows the current privacy problems as the web becomes more and more sophisticated and as the need to gather intelligence for national security increases. It also discusses the inference problems and the possible ways to eliminate this problem.
