Ann Cavoukian describes data linkage and her thought about a wrongly decided Canadian court case.
One of the problems with the personal data lockers concept is that fails to address the transfer-ability of data. This is the same problem that DRM faces. It tries to solve a problem by making something harder. In the case of DRM, it tries to make it harder to make copies or transfer data. What’s the result? Hackers and crackers come around to eliminate the self imposed technological barrier. Some thing with Personal Data Lockers, in my opinion. I’m not saying it won’t work in certain circumstances and to certain degrees but this solution is just an anti-productivity solution. I’ll try to write more about this in the future.
