    Happy International Privacy Day 2017

    January 24th, 2017

    International Data Privacy Day is Saturday. There are a variety of events occurring this week to celebrate, including a live-streamed event from Twitter in San Francisco on Friday. Visit the official site to find events near your area. Take the time to think about how privacy is important in your life and how you can protect your rights from being infringed upon. Please also donate to any number of organizations out there trying to protect your privacy rights.

    New Year? Time for a New Assessment of Your Privacy Setup.

    January 17th, 2017

    People use a lot of services and devices to transmit and retain sensitive personal information. A person could use daily: a work computer, a personal computer, multiple email addresses, a work cellphone, a personal cellphone, an e-reader or tablet, a fitness tracker or smart watch, and an Artificial Intelligence assistant (Amazon’s Echo, Apple’s Siri, Google’s Assistant, or Microsoft’s Cortana). The data retained or transmitted on these services and devices could include sensitive medical or other information, personal photos, financial data, and more.

    There’s also the issue of the collection of information that could lead to other data being learned. For example, I wrote recently about health-app data and the surprising results of scrutinizing it. A man was alarmed by his wife’s heart rate data, as collected by her Fitbit, and asked others for assistance analyzing it. One theory: She could be pregnant. Did you know that heart-rate changes could signal a pregnancy?

    Currently, there’s ongoing controversy concerning the data possibly collected by an Amazon Echo. The Washington Post explains, “The Echo is equipped with seven microphones and responds to a ‘wake word,’ most commonly ‘Alexa.’ When it detects the wake word, it begins streaming audio to the cloud, including a fraction of a second of audio before the wake word, according to the Amazon website. A recording and transcription of the audio is logged and stored in the Amazon Alexa app and must be manually deleted later.” Arkansas police have served a warrant to Amazon, as they seek information recorded by a suspect’s Echo. Amazon has refused to comply with the warrant.  Read more »

    It’s Becoming Easier to Have Detailed Secret Surveillance from a Distance

    November 23rd, 2016

    The idea of secret surveillance from a distance isn’t new. For centuries, there have been undercover agents. Subsequently, there came hidden cameras and microphones. But there were limitations to this secret surveillance — such as the physical constraints of a human or camera located far from the person being watched. As surveillance technology has become more sophisticated, however, it is becoming easier to identify, watch, listen to, and judge people from a distance.

    The judgment portion is, in part, based on biometric facial-recognition technology that incorporates expression recognition. For the unseen eyes, it’s no longer just about identifying a person, but also about watching their emotional responses. This type of facial-recognition tech gained attention a few years ago when Microsoft filed a patent for technology that would track individuals’ emotions and target advertising and marketing as based upon a person’s mood.

    “Degrees of emotion can vary — a user can be ‘very angry’ or ‘slightly angry’ — as well as the duration of the mood. Advertisers can target people ‘happy for one hour’ or ‘happy for 24 hours,’” the Toronto Star reported in 2012. Four years later, the mood-identification technology can be bought off the shelf, as NBC News explains in a story about “a new immersive experience for moviegoers.” Read more »

    Criminalizing the Reidentification of ‘Anonymized’ Data Won’t Solve the Privacy Issue

    October 17th, 2016

    For years, companies and institutions have been using “anonymization” or “deidentification” techniques and processes to release data concerning individuals, saying that the techniques will protect personal privacy and preclude the sensitive information from being linked back to an individual. Yet we have seen time and again that these processes haven’t worked.

    For almost two decades, researchers have told us that anonymization of private information has significant problems, and individuals can be re-identified and have their privacy breached. (I wrote a blog post last year detailing some of the research concerning re-identificaiton of anonymized data sets.)

    Recently, Australian Attorney General George Brandis announced that he would seek to amend the country’s Privacy Act to “create a new criminal offence of re-identifying de-identified government data. It will also be an offence to counsel, procure, facilitate, or encourage anyone to do this, and to publish or communicate any re-identified dataset.”

    According to the Guardian, the “impetus” for this announcement was a recent privacy problem with deidentified Medicare data, a problem uncovered by researchers. “A copy of an article published by the researchers outlines how every single Medicare data code was able to be reidentified by linking the dataset with other available information,” the Guardian reported.

    Latest in Employee Monitoring: Badges That Listen, Tracking Social Media

    September 19th, 2016

    Companies have been monitoring their employees for years, in a variety of ways. Employers are using key-logging technology to monitor workers’ keystrokes and Internet-tracking software to log the sites that employees visit. Ars Technica and others reported on Xora, a job-management app that was used by one business to track employees even when they were off the clock. The latest in workplace monitoring concerns employee badges as well as gathering social-media data on workers.

    Businesses have been tracking the movements of their workers in various ways, including through GPS-enabled smartphones and tablets. “Etta Epps, a UPS delivery driver for 10 years,” reports the Atlanta Journal-Constitution, “said she is keenly aware of the shipping giant’s surveillance of her actions through GPS and sensors in her truck.” ”You’re so conscious every day of trying not to do this or not to do that because you know you’re being monitored,” Epps said.

    Now, there is a new type of badge that can track employees even more closely. Humanyze, a Boston company, has created special surveillance badges that can be used in the workplace. “Each has two microphones doing real-time voice analysis, and each comes with sensors that follow where you are in the office, with motion detectors to record how much you move. The beacons tracking your movements are omitted from bathroom locations, to give you some privacy,” the Washington Post reports. Read more »

    Federal Case and State Law Are Latest Moves to Curb Warrantless Use of Stingray Tech

    August 8th, 2016

    The Stingray surveillance technology, also called cell-site simulator technology, can gather a significant amount of personal data from individuals’ cellphones. A recent federal case in New York and a new law in Illinois aim to curtail the warrantless use of Stingrays.

    The technology simulates a cellphone tower so that nearby mobile devices will connect to it and reveal sensitive personal data, such as their location, text messages, voice calls, and other information. The Stingray surveillance technology vacuums information from every cellphone within its range, so innocent people’s private data are gathered, as well. It is a dragnet that can capture hundreds of innocent people, rather than just the suspect targeted.

    As I have discussed before, law enforcement officials are using this technology in secret. Documents obtained by the ACLU showed that the U.S. Marshals Service directed Florida police to hide the use of Stingray surveillance technology from judges, which meant the police lied in court documents. Sarasota police Sgt. Kenneth Castro sent an e-mail in April 2009 to colleagues at the North Port (Florida) Police Department: “In reports or depositions we simply refer to the assistance as ‘received information from a confidential source regarding the location of the suspect.’” A recent San Diego Union-Tribune investigation showed that local police are using the surveillance technology in routine investigations – not ones involving terrorism or national security.

    Now, a federal judge in New York has thrown out Stingray evidence gathered without a warrant. The case is United States v. Lambis (pdf) in the Southern District of New York. Without a warrant, the Drug Enforcement Administration used a powerful cell-site simulator to determine the location of a cellphone was in Raymond Lambis’s home. Agents then searched his home and found drugs and drug paraphernalia. Read more »
