Hi,

Can anybody detail some approach on how to save private data in social websites like facebook, etc. They cant save all the updates and friends list in clear text format because of privacy issues. So how do they actually save it?

Hashing all the data with user password so that only a valid session view it is one possibility. But I think there are some problem with this approach and there must be some better solution.
