Secure multi-receiver data exchange for OSNs using predicate encryption
Abstract-Online Social Network is an extremely prevalent administration among utilizations of the web and distributed computing. Security assurance has turned into a noteworthy issue in light of the fact that a considerable measure of individual data is put away on the OSN stage. To make proceeded with tasks OSN stages require promotion income. Assume if clients encode their messages for security reason, the OSN suppliers can’t produce an exact notice to the clients who are associated with that system. It was exceptionally Intricate to all the while accomplish both securities safeguarding client’s information and also an exact advertisement to the clients. Thus a secure multi receiver data exchange scheme using predicate encryption plot is proposed for OSN systems which ensures clients security and furthermore accomplishes modified commercial too. Also, users are allowed to view data only for the specified amount of time allows no more data stealers can access data. Contrasted and other predicate encryptions that are conveyed for OSN stages proposed to conspire increases substantially shorter ciphertext.
