A Novel Image Steganography Method with Adaptive Number of ...
To enhance the embedding capacity of image steganography and provide an imperceptible stego-image for human vision, a novel adaptive number of least significant bits substitution method with private stego-key based on gray-level ranges are proposed in this paper. The new technique embeds binary bit stream in 24-bits color image (Blue channel) or in 8-bits gray-scale image....

 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...
Hybrid Medical Colored Image LSB Steganography Based on ...
process of steganography is done randomly and based on stego keys that are also derives from primitive roots of prime numbers. In 2015, Manjula and others proposed a technique called “Hash Based Least Significant Bit (2-3-3)” to insert 8 bits of secret data in LSBs of pixel value of the colored cover...
Reversible Secure Steganography Based On Lifting Transform ...
The secret image can now be extracted from this image using the following steps: Represent the stego image G in YCbCr color space.Find the integer wavelet transform of Cr component of the stego image G. Obtain the key from the least significant bit planes of the higher frequency components of the transformed image....
