A secure data cluster sharing and conditional dissemination theme with multi-owner in cloud computing, with in which data owner will share non-public data with a group of users via the cloud in an exceedingly secure manner, and data communicator will share the data 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 cipher text, within which the data co-owners will append new access policies to the cipher text 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 data. 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 multiple blocks and upload those blocks onto multiple clouds. As each block is on different cloud, if there is attack on any cloud the remaining blocks which are stored on other clouds will be safe, this is how we are providing more security to user’s data.
