Abstract: A secure knowledge cluster sharing and conditional dissemination theme with multi-owner in cloud computing, within which data owner will share non-public information with a group of users via the cloud in an exceedingly secure manner, and knowledge communicator will publicize the info to a brand new 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 ways, together with full permit, owner priority and majority permit, are provided to solve the privacy conflicts downside caused by completely different access policies. Many schemes are recently advanced for storing information on multiple clouds. Distributing data over completely different Cloud Storage Suppliers (CSPs) mechanically provides users with a definite degree of data run management, for no single purpose of attack will leak all the knowledge. However, unplanned distribution of data chunks will cause high information revealing even whereas exploitation multiple clouds. An efficient storage plan generation algorithmic rule supported cluster for distributing information chunks with least data escape across multiple clouds. So to provide more security to user’s data we will divide our data into blocks and upload each block to different cloud providers.

Keywords: Data Sharing, Conditional Proxy Re-Encryption, Attribute-Based Encryption, Privacy Conflict, System Attackability, Remote Synchronization, Distribution and Optimization
