Cloud computing is technique which has become today’s hottest research area due to its ability to reduce the costs associated with computing. In today’s Internet world, it is most interesting and enticing technology which is offering the services to various users on demand over network from different location and using range of devices. Since Cloud Computing stores the data and propagate resources in the open environment, security has become the main obstacle which is hampering the deployment of Cloud environments. So To ensure the security of data, we proposed a method which uses Multilayer Security for securing Data using Homomorphic Encryption in Cloud Computing. Homomorphic encryption is a form of encryption that perform computations on ciphertext thus generating an encrypted result which, when decrypted, matches the result of operations performed on the plaintext. This System helps to secure Data for various cloud users.
