A PROPOSAL ON PROTECTING DATA LEAKAGES IN CLOUD COMPUTING

In cloud computing we can store personal and business data. Cloud computing provides various features like less maintenance, more storage capacity, pay-per-use etc. But with this features cloud computing has some disadvantages like security and privacy. Existing data security mechanisms are not sufficient for the security of t he data. In this work, five layers of security of data have been proposed which makes data more secure on cloud. In the 1st two layers user authentication with one time password mechanism is proposed. Then in the next layers data encryption, access rights and in the final layer file will be split and store that file on different locations of server.
