When informed, GrubHub revised its code and had Crashlytics delete all the associated data that contained passwords.
The group extracts data from app communications, and tries to determine what parts of it are PII. This is both harder and easier than it might sound. But the team also applies machine learning, allowing it to identify PII more broadly, even when it appears without using any standard structure format, or shows up in surprising places. The ReCon project publishes some data derived from a few hundred early users, listing apps, the kind of data they passed, a severity score, whether a developer was notified, and when misbehavior was fixed if indeed it was.
For instance, a user can block all examples of a given kind of PII, or block all location data sent from a given app. However, because some apps fail without location coordinates, the team is looking into coarsening GPS information instead of blocking it entirely. Of course, examining a flow of data from users itself raises massive privacy red flags, which is part of the evolution of ReCon. At the moment, the tool measures and reports what apps are doing, though it could offer blocking controls in the future.

Fortunately, the two projects have both a friendly competition and plans for collaboration. The efforts will likely remain separate, but incorporate aspects or associate data to get a bigger picture about app behavior. And the ReCon team would like to develop software for a network appliance, a Raspberry Pi that would act as a sniffer or proxy or firmware for a network router, to let someone see the interactions across all network devices—especially Internet of Things equipment, which have all sorts of privacy and security issues of their own.
And that data is well-used by Uber to reassure customers that their journey is safe: Did you know that digital photographs contain information about the picture? Known as Exif data, the standard was created to hold stuff that photographers might find useful to know alongside the image, such as the focal length and aperture they used while taking it. In September , Facebook was even forced to disable the feature after the Irish data protection commissioner scolded it for doing so without permission.

Smartphones store a lot of personal data. Those devices know our names, the names of our friends, our address — and where we are, right now. Some apps use those data to do their job.

A weather app needs to know where a person is to report the local forecast, for example. But those same apps may often send such data on to advertisers as well.
Those advertisers will pay well to know how people behave and live. Krupp agrees that it is important for phone and tablet users to know where their data go.

And that data theft may not be harmless. Those data may reveal when someone leaves home and when they get back. They can show how — and where — people spend their days. Researchers have begun building smartphone programs that track the misuse of such data.
Listening In On Your Behalf
That means they have to take the phone apart and change the way its computer or software works. And many of the others would not be comfortable breaking into their phones. SPEProxy identifies the misuse of data using an approach that has already been used in medicine to diagnose illness. That medical software collected data from a patient's blood samples and from other measurements. Then it compared them to those typical of many possible illnesses to make a diagnosis.
Stop iOS tracking
Krupp's group has now built a new computer program that tracks how apps leak data. It allows users to see what data are leaked, and where they go. It also lets a user limit what type of data an app can access from the phone. People in the audience immediately reached for their phones to check on their apps, he says. Right now, people can only track data with the new tool by going to a website.
