Identity, privacy and security

I think the recent trend in Web 2.0 social networking communities and the way that mobile services are now being widely used the industry is starting to sound louder about issues regarding personal identity, privacy and security. I am not the best person to talk about this, only that recent events I have attended these have been some of the top most debated points and worries that people have. Is it enough to say the kind of arguments such as 'If you havent got anything to hide you have nothing to worry about'? You hear people say this a lot when the debate is about the possible introduction of UK citizen identity cards. However, when you talk to people in the know, you start to realise that identity theft can actually be a convenient way of not so honest people to do what they like under your name with no or little way to trace who they are are, laying blame at the doorstep of the innocent. So how do you protect your identity and keep what really matters private? Most people on the internet have a tendency to use the same password for all of their logins, this is very dangerous. With the rise in usage of things like internet banking, online purchases, election voting, blogs and so on, ID theft and the tracability of activity on the web brings around some disturbing possibilities. As Product Manager at Ymogen, we are building a collaborative tool to build rich media stories, and we will have to be very careful when we think about how we can protect identity. We also need to think about moderation to protect people such as children when it comes to the content people will put into stories. The internet is said to support the concept of Liberalism, but the community at the moment on the internet seem to fail to understand the responsibilities required to protect and secure people, their privacy and security.
