Abstract: Cloud security is an emerging concept in data outsourcing in the cloud and also maintaining of multiple copies of each user in different servers is crucial task in data outsourcing in terms of customer cost, memory storage in multi user access in real time distributed systems. Traditionally a Map-Based Provable Multicopy Dynamic Data Possession (MB-PMDDP) plan that has the accompanying components: it gives a proof to the customers can utilize that the CSP is not unfaithful by sparing less duplicates, it encourages outsourcing of intense data, i.e., it encourages piece level capacities, for example, forestall modification, arrangement, evacuation and append and it permits endorsed customers to effortlessly get to the information record copies spared by the CSP. For example consider e-Health care systems for providing security to patients sensitive information with modifications (like insert, deletion, updation) by different peoples and store those files in different servers causes loss of security to patients because of corrupted data in different servers. To support above considerations in multi user data access in this study, we propose to develop, incorporate solace with versatile therapeutic consideration frameworks with the assistance of the private evaluation. Our framework offers critical components, for example, successful key control, security, safeguarding data storage room and recuperation, particularly for recuperation at crisis circumstances and auditability for abusing wellbeing data. Especially, we prescribe to consolidate key control from the pseudo interesting number maker for unlinkability, a sheltered and secured posting technique for solace ensuring catchphrase and key expression search for which disguises both search for and access designs taking into account repetition.
