Image steganography on color image using SVD and RSA with 2-1-4-LSB technique


Steganography is the method of covering text within some form of cover file. This paper presents a new method for data communication over an unsecure medium. In this apply RSA to keep data secret and increase security level using encryption and decryption method. Encryption is performed with the help of a key which makes it hard to get the secret message… (More)
