Normally the data is encrypted by making use of some keys to prevent the data from theft. To retrieve the data back the key must be known if the key is known to the intruder then there is no use of encrypting the data to overcome this even though the riddle key is known then. Restricting data retrieval is as effective as encrypting the file. Although existing access control plans are not any more relevant to distributed storage frameworks, since they either create different scrambled duplicates of similar information or require a completely trusted cloud server. Cipher Text Policy Attribute-based Encryption (CP-ABE) is a promising procedure for to get control of scrambled information. In any case, because of the wastefulness of unscrambling and disavowal, existing CPABE plans can't be specifically connected to build information get to control conspire for multi-specialist distributed storage frameworks, where clients may hold qualities from different experts. In this paper, we propose a system which can effectively carry out the data restriction by implementing multiple authorities so that only a verified user gets to access data so that data theft can be restricted
