“…As per [5] D.H.Tran, H.-L.Nguyen,W.Zha , and W.K.Ng, public is giving attention to some of the privacy issues online social networks (OSNs) when the users and the OSN providers are not agree when the data privacy is caused. The providers use the users' data for the commercial purposes to make the growth of their profit while the users feel that their privacy and security has been decreased by this type of the behavior.…”

In world of Internet, the concept of group data sharing is gaining very high popularity. The privacy and security of group data sharing are the main issues which are to be considered while using this concept. Due to the semi-trust nature of the third party, it cannot be trusted and hence, security models used traditionally cannot be directly applied to the framework of cloud based group sharing. In this paper, implemented framework for a secure group sharing for public cloud, which can take the advantages of Cloud Server's help very effectively. Only difference is that the chances of data insecurity would be reduced and the threat of data being exposed to attackers and cloud provider would be reduced simultaneously. Framework is formed by combining Proxy signature, enhanced TGDH and proxy re-encryption together into protocol. The use of proxy signature technique is that the group leader can grant the privilege of group management to one or more chosen group members. With the help of cloud servers, the enhanced TGDH scheme enables the group to update and negotiate group key pairs thus all group members need not to be online all the time. By using proxy reencryption most of intensive operations which are to be performed computationally can be handed over to the cloud servers without the threat of disclosure of any private information. The security requirements for public cloud based secure group sharing are fulfilled by our proposed scheme with high efficiency and it can be proved by the extensive security and performance analysis.

“…There are two types of searchable encryption scheme, searchable publickey encryption scheme (SPKE) [5] and searchable symmetric encryption scheme (SSE) [9]. Two works of privacy-preserving OSNs [18] [17] has adopted SPKE for online data search. However, to achieve user efficiency, SSE is more suitable in mobile environment because SSE requires less computation cost than SPKE.…”

Abstract-The privacy issue of online social networks (OSNs) has been getting attention from the public, especially when data privacy has caused the disagreement between users and OSN providers. While the providers utilize users' data as a commercial usage to make profit; on the other hand, users feel their privacy has been violated by such behavior. In this paper, we propose a privacy preserving protocol for users' data sharing in OSNs, where the OSN provider cannot retrieve the users' social content while the users can efficiently add or remove a social contact and flexibly perform the data access control. Moreover, we prove that the users would allow the OSN provider to perform keyword search over the encrypted content for advertising profit, so that the OSN provider can commercialize its products without the knowledge of content.
