Either way these are popping up everywhere, on the back of products in supermarkets and pharmacies, movie posters, ads on buses and in magazines.
By is using an app that piggybacks on your smartphone camera you can rapidly capture and use the data inside these graphics.
I’m not going to get into arguments about which is better, supported by more phones etc. both work and are easy to implement.
The fact is, this data encoding technology in graphics is both a really neat tool and potentially an easily exploit for getting malicious code onto someone’s mobile device.
At present I have found no security application that scans Tags or QR Codes prior to any device decoding the embedded data. At the simplest level it could be a URL leading to a malicious site. I’m not going to speculate at the worst.
Your mobile device decodes these on the fly and in the case of MS Tag Reader you are connected to the internet to do this.
Recently I have been doing some testing related to these and whilst working on a novel it occurred to me this could be a great plot device using either this way or else as simple steganography .. how I use it in the novel you are just going to have to wait and see. My writing occurs in fits and starts as inspiration hits me 🙂
This “tags” on nicely to my earlier piece on Smartphone security anyhow, what do you think about Microsoft Tags and QR Codes; have you used them yet?
