Re: Single point of security failure
"a primary target for all hackers after exploitable personal data"
Indeed, this seems to be a fairly large flaw with the whole idea. Instead of putting bits and pieces of your data all over the place as and when it's asked for, you pre-emptively put it all in one place and wait for someone to
ask you for access to it access it without you knowing. It's just another cloud with all the issues that always brings.
Worse, even if it were perfectly secure it wouldn't actually achieve anything anyway. The problem with personal data isn't that it's too easy to gain access to it, it's that once it's been given out for any reason, it's trivial to copy it and hand it around. It doesn't matter how secure you make your central data store, as soon as you give anyone permission to look at any of it, all the data they've seen is in exactly the same situation as if you had no central store at all. In order for the idea to work, you have to trust everyone who is given access to any of your data, but the entire reason for proposing it is because most parties aren't trusted. It's a neat idea that completely fails to actually address its only objective.
