CryptMe: A Cryptographic framework with Steganography for securing data

Abstract

Data Security has become one of the major concerns in the modern world. As everything is going digital and our data is on the cloud, its security is a major research area. The various suggested method provides better security and more important integrity. However, with more advancement in technology, these proposed methods are getting snooped. This paper proposed an approach of a combination of Steganography, Cryptography, and Transposition cipher technique. In particular, it focuses on the LSB technique in another way i.e., while performing the LSB steganography technique instead of embedding data at LSB of the base image, this method takes MSB of Video Frame and LSB of Stego Image. This combination helps in providing very little distortion and higher quality of the secure image. The value of efficiency of the algorithm would be determined by the PSNR value.
