However‚ several cryptographic methods are available such as symmetric-key encryption‚ Caesar’s cipher and public key cryptography [2]. By using these methods several data encryption methods have been implemented. A. Pretty Good Privacy (PGP) This data encryption and decryption program is often used

The WinFS File System In the last decade there has been a “combination of trends and technologies” that will change the way people work with managing their data in the future. Because computers have become faster‚ bandwidth continues to increase‚ and data storage has increased‚ the amount of “digitally born data” has exploded (Rizzo‚ 2005). The increase in digital data has propelled Microsoft to invest in building a new way to manage data. WinFS (Windows Future Storage) is being developed by Microsoft

CHAPTER 1 1.1 INTRODUCTION Data that can be read and understood without any special measures is called plaintext or cleartext. Here Plain image is converted as Plaintext.The method of disguising plain image in such a way as to hide its substance is called encryption. Encrypting plain image results in unreadable gibberish called cipher image. You use encryption to ensure that information is hidden from anyone for whom it is not cipher image to its original plain image is called decryption. Figure

MLE provides a way to achieve secure deduplication (space-efficient secure outsourced storage)‚ a goal currently targeted by numerous cloud-storage providers. We provide definitions both for privacy and for a form of integrity that we call tag consistency. Based on this foundation‚ we make both practical and theoretical contributions. On the practical side‚ we provide ROM security analyses of a natural family of MLE schemes that includes deployed
