lsb-method

Steganography is a technique for transmitting information without detection.Least Significant Bit (LSB) embedding is a simple strategy to implement steganography. Like all steganographic methods, it embeds the data into the cover so that it cannot be detected by a casual observer.

opap-method-steganograohy

a modification on the LSB method has been proposed using an optimal pixel adjustment process to reduce the mean-squared-error between cover image and stego-image.

pvd-method-steganograpghy

The pixel-value differencing (PVD) scheme provides high imperceptibility to the stego image by selecting two consecutive pixels and designs a quantization range table to determine the payload by the difference value between the consecutive pixels. Besides, it offers the advantage of conveying a large number of payloads, while still maintaining the consistency of an image characteristic after data embedding.
