Data Security in Cloud Environment Through Data Logs

This Paper proposes use of public cloud for storing and accessing confidential data. Data confidentiality is assured by using encryption technique, in which the data is stored on public cloud is encrypted using encryption algorithm. The encryption algorithm used in encryption technique is AES.With the help of this method of using public cloud, the cost efficiency increases as public clouds provide many services such as service on demand, scalability, pay per use, inexpensive hardware set-up etc. There is a vulnerability to data security while using public cloud, since for confidentiality one has to rely on third party, but if encryption technique is used with data logging to keep track of the people accessing the cloud then the vulnerability to the data confidentiality can be eliminated.
