— Due to the extensive application of Cloud Computing and Web application, collaborative technologies are popular, like Google Docs, Office 365 allows access to all files, from which real time many client can be edit document. By security considerations, cloud service providers can read Client's confidential information, while using collaborative editing system. These services access documents third-party sources, which mean that Remote hacker it can be directly accessible to those who have basic structure, their governments, security breaches, In this existing, AES 256 bit algorithm uses the client for data security. Improving the security of the client data in cloud based collaborative system using MAES algorithm. In this, using the AES 512 for the collaborative system and also change in Mix coloum and shift row step. There is a proposal to improve security. So client data is encrypted safely, we have to evaluate the encrypted document size(kB), encryption time(ns) and throughput(kB/ns). AES 512 algorithm is reliable and this gives negligible encryption time(ns) and provide more security. The size of the key difficult to determine in AES 512 algorithm so, the hacker or attacker is difficult to obtain original text from the collaborative editing system.
