 A Secure Image Steganography Based on RSA Algorithm and ...
The Least Significant Bit insertion varies according to number of bits in an image [16]. For an 8-bit image, the least significant bit i.e. the 8th bit of each byte of the image will be changed by the 1-bit of secret message. For 24 bit image, the colors of each component like RGB (red, green and blue) will be changed. LSB steganography...
EasyStego: Robust Steganography Based on Quick-Response ...
This method is based on the use of the DES and RSA algorithms to achieve secret-message encryption, which increases the difficulty of cracking secret messages. Ramesh et al. proposed an image-steganography scheme based on frequency-domain processing. It uses discrete-wavelet transform (DWT) to conceal secret messages in the carrier image as a ......
A Secure Image Steganography based on RSA Algorithm and ...
The Hash based Least Significant Bit (H-LSB) technique for steganography in which position of LSB for hiding the secret data is deermined using hash function. Hash function finds the positions of least significant bit of each RGB pixels and then message bits are embedded into these RGB pixels independently....
