Cloud Based Security

As we all know that internet is progressing in the terms of social networking website and the site which highly interact with the user also the use spent more time on this kind of website. Also user share their personal information, some important data, photos among various people that may belong their group or community so the security for all this things is mandatory but most of the time the site doesnt give proper attention toward this security requirement by which the user information may leak by unauthorized person. so in this paper we are trying to secure the informa tion of users using different compression and encryption algorithm and the address of information from users. This data is stored at various places on internet which is scattered on worldwide . So when any authorized person is trying to access his data that person only get all the information about his data but still he will never know the location of that data. The system we developed in thi s paper allows the user to upload all his data in any format including the security feature like compression and encry ption. This all uploaded data and information can be access from anywhere in the world. So finally we can say that we developed the very secure system to store the important info rmation on website in a very effective & secured manner

Reverse Encryption Algorithm: A Technique for Encryption &Decryption

Abstract -In the today's world, security is required to transmit confidential information over the network. Security is also demanding in wide range of applications. Cryptographic algorithms play a vital role in providing the data security against malicious attacks. Encryption of data is an important topic for research, as secure and efficient algorithms are needed that allow optimized encryption and decryption of data. In this paper we propose a new encryption algorithm, called Reverse Encryption Algorithm (REA). Our new encryption algorithm (REA) is simple and fast enough for most applications. REA encryption algorithm provides maximum security and limits the added time cost for encryption and decryption
