types of steganography techniques
{"Image DocumentName": "Steganography : Techniques", "Image ImageDescription": "There are two basic types of steganography: Spatial steganography: There are many versions of spatial steganography, all directly change some bits in the image pixel values in hiding data. Eg LSB ( Least Least significant bit (LSB)- based steganography, is a type of spatial Steganography algorithm that hides a secret message in the LSBs of pixel values without too much perceptible distortions. It should be noted that to our human eye, any change in the value of the LSB are imperceptible. Embedding of message bits can be carried out either sequentially or randomly. Least Significant Bit (LSB) replacement, LSB matching, Matrix Embedding and Pixel value, differencing are some of the spatial domain techniques. Transform steganography: The process of embedding data in the frequency domain of a signal.
