Abstract: With the fast development of cloud services, immense volume of knowledge is shared via cloud computing. Although cryptographic techniques are utilised to supply information confidentiality in cloud computing, current mechanisms cannot enforce privacy issues over ciphertext related to multiple house owners, which makes co-owners unable to fitly control whether or not information disseminators will truly air their information. during this paper, we have a tendency to propose a secure information cluster sharing and conditional dissemination theme with multi-owner in cloud computing, within which information owner will share personal information with a group of users via the cloud during a secure means, and information propagator will air the info to a replacement cluster of users if the attributes satisfy the access policies within the ciphertext. We have a tendency to additional gift a multiparty access management mechanism over the disseminated ciphertext, within which the info co-owners will append new access policies to the ciphertext thanks to their privacy preferences. Moreover, 3 policy aggregation methods, as well as full allow, owner priority and majority allow, are provided to solve the privacy conflicts drawback caused by totally different access policies. The safety analysis and experimental results show our theme is sensible and economical for secure information sharing with multi-owner in cloud computing.
