Privacy Flaws In Chatroulette Expose Users 101

from the users-exposed-themselves-just-fine dept.
itwbennett writes "In a paper posted online this week, researchers from the University of Colorado at Boulder and McGill University outline three different types of attacks that could be launched against Chatroulette users. While the new research doesn't expose any gaping privacy holes, it does show how the service could be misused by determined criminals. For example, the researchers were able to use IP-mapping services to get a general idea of users' location (a public Web site, called Chatroulettemap.com already does this). Then by searching Facebook using information obtained in chats and comparing pictures, researchers were able to identify chatters. 'Even in a city as big as Chicago, you can drill down and find the person you're actually talking to,' said Richard Han, an associate professor with the University of Colorado who co-authored the paper."

    Privacy Flaws In Chatroulette Expose Users

    Trust me, on Chatroulette it's the users that have been exposing themselves.

      I was visiting a friend of mine in San Fran a few months ago. He got a new Apple laptop, so he was showing it to me. We tried out Chatroulette briefly, and the third session ended up being a close-up of some guy touching his penis. The first thing my friend wrote was "Jim, is that you? It's Freddy."

      My friend recognized the other guy by his penis. Turns out they knew each other from a gym they both went to, where they'd seen other naked in the showers. They both thought it was a really funny coincidence to meet on Chatroulette like that.

    For one simple reason. Facebook does not let you set your profile picture to a shot of your genitals.
  • So the security flaw is that by asking someone for personal information you can obtain personal information about them? This is called social engineering (or maybe just talking).

    "Chatroulette is a website that pairs random strangers from around the world together for webcam-based conversations. Visitors to the website randomly begin an online chat (video, audio and text) with another visitor. At any point, either user may leave the current chat by initiating another random connection. As of July 11 the site is offering an experimental "localized" version which pairs people by state". -wikipedia

    So 1.) people find each-other intentional and 2.) "using information obtained in chats" I can get you SSN... if you tell me.

        I can always sniff out the ip address of the host I'm communicating with, even if all of the data is encrypted. The only way to prevent that is to run all of the data (video, audio, and text) through a central server (or multiple central servers) or some type of proxy. The point is, someone is going to have to pay for a huge amount of bandwidth, as opposed to the way it works now where all the main server has to do is arrange the connections.

      I'm actually a CU-Boulder student and had a class with Han last semester. He's a great prof and really cares about the students' understanding. I was surprised to see that he put out research on something so common-knowledge; "Oh once you have a picture of someone you can look for another picture that looks like it and you know you've found your target". He's more of an operating systems/networking kind of guy. This just seems like fluff research to keep the department chair happy while he actually does his teaching and "real" research. Academia has this tendency to prioritize quality over quantity, and I think this provides an example of the pressures even good profs feel from the top re: publishing.

        That's a very generous assessment. Obviously, I don't know the guy, but another possible hypothesis is that he's made the oft-repeated mistake of an expert outside his own field, who thinks he's also good enough to be an expert in another field. Academia is chock full of this -- having a good publishing record in one field tends to inflate one's ego, and can frequently lead to moronic research in even a closely related field.

    I thought this was the exact issue the U.S. miltary had when they had soldiers posting geotagged pictures to facebook which identified where they were in Afghanistan. Same idea - people, given a few small details, can very easily find out about you by the use of Google.

    Back when I was in first year university (1996) it was still pretty wild west on the internet. I was talking to a friend who I had never given any of my real details (name, address, etc) when she popped up and asked if I went to AMHS (my high school). After picking my jaw off the floor I found out that I had mistakenly forwarded them an E-mail which I had originally forwarded from my school account to my hotmail account. They found the e-mail address, and googled it. It was all laid out there on the Universities' website.

    • I believe the Facebook issue is fairly different. In that case, it's not Facebook doing the geotagging, it's fancy new cameras (often built in to smartphones) that tag the image file itself with the location, as best as the camera can determine it at the time. Facebook then just makes that metadata easily available.

      In this situation, it's the obvious problem of a peer-to-peer connection, namely that each peer knows the other's IP address, and from that you can start to narrow down a location, often fairly

      • I thought facebook stripped all metadata?

        When you upload a photo to facebook, it is heavily compressed into a few stock sizes. The focus on compression to speed things up and save bandwidth is probably at the point of removing the few bytes taken by even the most basic EXIF data...facebook photo can be flipped through incredibly quickly (due to optimization and preloading). I am sure they keep that data stored safely away somewhere (and may someday add the ability to view it), but it certainly isn't in
