The goal was to help researchers, and the state spent time removing all obvious identifiers such as name, address, and Social Security number. But a graduate student in computer science saw a chance to make a point about the limits of anonymization."

Professor Sambuddho Chakravarty, "a former researcher at Columbia University’s Network Security Lab and now researching Network Anonymity and Privacy at the Indraprastha Institute of Information Technology in Delhi, has co-published a series of papers over the last six years outlining the attack vector, and claims a 100% ‘decloaking’ success rate under laboratory conditions, and 81.4% in the actual wilds of the Tor network."
"Recently, thanks to a Freedom of Information request, Chris Whong received and made public a complete dump of historical trip and fare logs from NYC taxis. It’s pretty incredible: there are over 20GB of uncompressed data comprising more than 173 million individual trips. Each trip record includes the pickup and dropoff location and time, anonymized hack licence number and medallion number (i.e. the taxi’s unique id number, 3F38, in my photo above), and other metadata."
Yves-Alexandre de Montjoye : "We study fifteen months of human mobility data for one and a half million individuals and find that human mobility traces are highly unique. In fact, in a dataset where the location of an individual is specified hourly, and with a spatial resolution equal to that given by the carrier's antennas, four spatio-temporal points are enough to uniquely identify 95% of the individuals. We coarsen the data spatially and temporally to find a formula for the uniqueness of human mobility traces given their resolution and the available outside information.
What is Privacy? New Research Reveals We May Need a New Definition. If you still believe your personal credit information is truly private, newly released research by a Rutgers professor may lead you to reconsider.

Unique in the Crowd: The privacy bounds of human mobility : Scientific Reports. Uniqueness of human mobility In 1930, Edmond Locard showed that 12 points are needed to uniquely identify a fingerprint30.
Our unicity test estimates the number of points p needed to uniquely identify the mobility trace of an individual. The fewer points needed, the more unique the traces are and the easier they would be to re-identify using outside information. There’s No Such Thing as Anonymous Data. Photo by Andrew Nguyen About a decade ago, a hacker said to me, flatly, “Assume every card in your wallet is compromised, and proceed accordingly.”
He was right. Consumers have adapted to a steady thrum of data breach notifications, random credit card charges, and out-of-the-blue card replacements. A privacy-industrial complex has sprung up from this — technology, services, and policies all aimed at trying to protect data while allowing it to flow freely enough to keep the modern electronic bazaar thriving. A key strategy in this has been to “scrub” data, which means removing personally identifiable information (PII) so that even if someone did access it, they couldn’t connect it to an individual. » Goodbye Internet Anonymity: Swedish Tabloids Publically Shame Forum Users.

Me and my data: how much do the internet giants really know? To briefly state the obvious, the internet giants are seriously big: Google is not only the world's largest search engine, it's one of the top three email providers, a social network, and owner of the Blogger platform and the world's largest video site, YouTube.
Facebook has the social contacts, messages, wallposts and photos of more than 750 million people. Given that such information could be used to sell us stuff, accessed by government or law enforcement bodies (perhaps without warrants, under legal changes), or – theoretically, at least – picked up by hackers or others, it's not unreasonable to wonder exactly how much the internet giants know about us.

A claim by the Department of Health that patient data shared with private firms for medical research would be anonymised has been challenged by privacy campaigners.
The prime minister said last week that plans to share records and other NHS data would make it easier to develop and test new drugs and treatments. The DH says all necessary safeguards would be in place to ensure protection of patients' details. But Ethics and Genetics, a social and technology campaign group, says freedom of information requests show that under certain circumstances data anonymity would not always be guaranteed.
Data accessed under the secondary uses service, which is jointly delivered by the NHS Information Centre and Connecting for Health (CfH), for the NHS and its partners, is not always anonymised.

OCR issues guidance on methods for de-identification of PHI. As mandated by the American Recovery and Reinvestment Act of 2009, on November 26, 2012, the U.S. Department of Health and Human Services’ Office for Civil Rights (OCR) issued guidance on the de-identification of protected health information (PHI) in accordance with the HIPAA Privacy Rule (Privacy Rule). This tool, which is set forth in a navigable Q&A format, is the result of stakeholders with practical, technical, and policy experience contributing to a Washington, D.C. workshop in March 2010. The resulting guidance does not change the Privacy Rule, but rather clarifies the existing regulation as it pertains to de-identification of PHI. What You Don't Know about Your Online Reputation Can Hurt You - PCWorld Business Center.
Social networking, and the broader concept of online privacy, have been under some rather intense scrutiny over the past couple of weeks. The issues at Google--voracious indexer of all things Internet, and Facebook--the largest social network and number one most visited site (according to Google) have made many users more acutely aware of what information is available about them on the Internet.
