STEGANOGRAPHY process Three basic ways to encode data in steganography: Image as a carrier Pixel representation in RGB Bandwidth reduced file transfer

13 слайд

1.IMAGE AS CARRIER:   It is an efficient technique for steganography, An image is used as cover for hiding the actual data. Digital images are a preferred media for hiding information due to their high capacity and low impact on visibility. 2.PIXEL REPRESETATION IN RGB: Basic RGB color model, every pixel is represented by the four bytes namely Alpha, red, green, blue Alpha: degree of transparency Red: intensity of red color Green: intensity of green color Blue: intensity of blue color The alpha bit is used to carry the data, as it has no much importance in image representation.

3.BANDWIDTH REDUCED TRANSMISSION:    If an image data takes six minutes to transfer between two systems and a text file takes 3 minutes. One can use steganography technique in order to reduce the time taking by embedding the text in the image and the total content will be transferred in six minutes.   Two basic algorithms used for steganography are Text on Image algorithm. Image on Image algorithm.
