The Adaptive Authentication in the Collaborative Systems: Applying the Time Authentication into the Certified Originality of Digital Contents

We would like to discuss the Adaptive Collaborative Learning (ACL) on the Cloud Services, which integrates different systems and applications into one comprehensive system. It is expected that time-stamp will be effective in 1. Evidence of the existence, 2. Proof of delivery, 3. Long storage of electrically signed contents. The purpose of our study is to incorporate the authentication roaming technology with existing social infrastructures from the perspective of users instead of that of service providers. The experimental pilot studies conduct on the ACL and provide further observation for applying the ACL. And we discuss the ACL would affect the Learning Fields.
