Computer Engineering

Nowadays the online business for various fields shows good margin as it is more simple and sophisticated nature. While doing online business many data holders can share data with some third-party vendors and then through that data vendors will share it to the end users. While processing these things if data owner wants to sell some digital content over the internet resources then currently it is very hard to keep track over data security, maintaining privacy and keeping integrity. This paper presents a novel approach to keep digital content more secure and consistent by applying various level of encryption to the files and also to the meta-data of files. Whenever data contributors upload digital content to the server, then service provider will send the unique key to user and when service provider sells this digital content to data consumer the internal details (meta-data) of file is also gets encrypted by Elgamal Algorithm hence if any unauthorize person access the original data though it will keep secure for modifying.
