Google Android Apps Leak Data

A research paper for USENIX, “TaintDroid: An Information-Flow Tracking System for Realtime Privacy Monitoring on Smartphones”, accuses android applications of leaking information without user approval.

Using TaintDroid to monitor the behavior of 30 popular third-party Android applications, we found 68 instances of potential misuse of users’ private information across 20 applications

Fifteen of the apps sent user data to advertising companies without user approval or notice, while other apps sent unique IDs and tracking/location data (even when the application did not run).

ATM upgrades may be forced by US Treasury

An argument against upgrading ATMs in the US has long been related to cost. The number of devices, their age and diversity, and the wide distribution area all make for a daunting process. Remote upgrades, even if possible, are not sufficient to thwart the latest skimming attacks. The hardware also has to be replaced.

A flush face, for example, would prevent any kind of skimming device. Imagine a plain glass interface with a touch screen and a slot, like a giant iPad. Anything placed on the glass would be a dead giveaway. Chip and pin, likewise, could be installed so Americans could enjoy some of the same security features found abroad. The possibilities for anti-fraud are great, except for the problem of getting new hardware into the field. Fraud has apparently not been cause enough for a major overhaul.

This could soon change due to a ruling by the US government related to the Treasury Department’s upcoming plan to make money accessible to the blind and visually impaired per the 1973 Federal Rehabilitation Act. The general counsel of Cardtronics, which runs tens of thousands of ATMs, has this to say in response to the plan:

“Cardtronics will be adversely affected should such a change in currency force us to make hardware and/or software changes in order for our ATMs to continue to function properly,” Keller wrote. “Retrofitting ATMs all over the country is costly not only due to purchasing the hardware/software upgrades from the manufacturer, but the labor and travel associated with a large number of upgrades required in a relatively short period of time. In some cases, retrofitting older models is not possible and would require us to replace such ATMs.”

He likens innovation in hardware to a drag on the industry:

In addition to causing ATMs to jam, an ill-designed tactile character would lead to fewer bills being placed in each cassette, Keller wrote. “Both problems could stall the industry and, in turn, stall commerce,” he said.

…or it could spur commerce though increasing the customer base, while reducing the cost of improving security and lowering ATM fraud risk.

CA SB1268 Locational Privacy Law

A bill called the “FasTrak Privacy Bill” has been signed by the California Governor into law. It was authored by State Senator Joe Simitian

Senate Bill 1268, protects “locational privacy,” a person’s right not to be tracked while driving, in the following ways:
— Prohibits transportation agencies from selling or sharing personal data;
— Requires them to purge the data when it is no longer needed;
— Sets penalties for violations; and,
— Ensures that FasTrak subscribers are given notice of the privacy practices affecting them.

“There’s just no reason for a government agency to track the movements of Californians, let alone maintain that information in a database forever and ever,” said Simitian.

This is a great idea and nicely worded but I see a couple ways companies might try to get around this law. First, the data may not be clearly owned by the transportation agency. FasTrak data is agency specific but not cell phone or bluetooth data, both of which also are tracked and recorded as location data. If an entity is not under contract with a transportation agency it is excluded. The transportation agency can be just one consumer of the data rather than the clear steward or owner. Second, this is complicated by cloud and similar shared data environments with multiple tenants working on “traffic congestion” and “interoperability” projects.

The bill has a “fact sheet” that helps clarify the final text. Note the exception for search warrants:

A transportation agency may make personally identifiable information of a person available to a law enforcement agency only pursuant to a search warrant. Absent a provision in the search warrant to the contrary, the law enforcement agency shall immediately, but in any event within no more than five days, notify the person that his or her records have been obtained and shall provide the person with a copy of the search warrant and the identity of the law enforcement agency or peace officer to whom the records were provided.

The retention period says personal information other than billing data has to be purged within six months after the billing cycle ends, and all information has to be purged within 150 days after an account is closed.

Penalty for violating location privacy is set at “actual damages” or $2,500 for the first three violations; $4,000 for each violation after that as well as cost recovery including attorney’s fees.
