A SURVEY ON DIFFERENT ENCRYPTION TECHNIQUES FOR IMAGE, VIDEO, AUDIO AND DOCS

Abstract

Encryption and Decryption of different files by various cryptography methods has been studied by the R&D community for years. Cryptography methodology has advanced considerably throughout the years, and plenty of encrypting techniques are currently offered to be used as per the necessity. Also, there has recent development in these techniques to satisfy the ever increasing demand of providing higher and economical security of the info. Having such a big amount of cryptography ways makes it very exhausting to settle on one. Though selecting the correct encryption methodology as per the necessity is incredibly necessary. In this paper, we have analysed and studied different encryption methods like AES, DES, RSA, Blowfish and Twofish for different types of files like Docs, PDFs, Images, Audio, and Video. The end result is concluded based on the different performance parameters and a brief and clear conclusion is made for each method.
