I was at the recent OECD Conference on the Evolving Role of Individual in Privacy Protection: 30 Years after the OECD Privacy Guidelines. One of the issues that was discussed was the right to be forgotten. This is analyzed in an extremely readable book, Delete, by Victor Mayer-Schonberger. The problem is simply that digital memory is eternal: stupid stuff that we say online, or pictures that perhaps we shouldn’t have uploaded, are there for ever. You might take down the picture, but if someone has already saved it and distributed it, it’s out of your control.
A solution that people are beginning to think about is the idea of an automatic self-destruct feature for stuff we put on Facebook and other social networks. In other words, unless you specifically request otherwise, any update or comment you write on Facebook, say, would disappear after a certain period of time. This would make it harder for future employees (or dates) to prejudge you on a youthful indiscretion, as the automatically deleted stuff would not appear when they Google you (and they will Google you).
There is, of course, no business case for doing this. The more data Facebook has about us, the more accurate profiles it can sell to advertisers. So there are two ways something like this could happen. The first would be through regulation, the second would be through consumer power. I wouldn’t count on either of them.
