SoKey: New security architecture for zero-possibility private information leak in social networking applications

We propose new security architecture, Socially Keyed (SoKey) architecture, to achieve zero possibility for personal information leak from social network sites (SNS). SoKey makes sure that the private information provided to a social networking server will never leak even in the worst cases, such as when the security administrators involve in information thefts, at the same time it allows flexible access controls to the users who have access permission. The master key server is also introduced, which guarantees no possible leak of the master keys. We designed and conducted a questionnaire to study how much SoKey would contribute to SNS users by mitigating or eliminating their fear for possible information leak. We found that SoKey will contribute to the people who are already using a social networking application.
