Block chaining is the mechanism by which users can differently accounts within same cloud storage. The cloud environment is used in block chaining to provide the resources on shared basis. In normal situation, single user can have only one account and if other user tries to login into the system causes the chained attack. The chained attack is also known as collision. The proposed work provides the solution to this chained attack. For solving the issue, multiple tag support is provided within cloud environment. To provide the security, BLOCK CHAINING based encryption is collaborated along with multiple tag support. The proposed work provide the facility to the user for adding more records within same account using the facility of multiple tags. The collision problem is completely eliminated using the proposed work with multiple tag support. The security is enhanced since key formation is more complex as compared to mechanism without random key generation. The result of the proposed work is expressed in the form of through indicating total output, encryption time and decryption time. The result is improved by the significant margin using the proposed work that is in the range of 10% as compared to approach without multiple tag support.
