A Survey on Data Loss prevention Techniques

This paper presents a way of encrypting data using an ephemeral cryptographic key since the importance of data loss prevention or data security is increasing nowadays. In this paper, On the fly Encryption is used for data loss prevention, by which an entire drive or a file that mounts as a virtual disk, a partition of hard disk or a device like a USB can be encrypted using an ephemeral key. The encrypted drive is made useless unless a USB drive key and a password that will be included. This paper also presents a way in which email can be downloaded and can be stored encrypted for future reference when internet connection is not available.
