This Algorithm accepts the user message and change some pixels values of an Image. Pixel values modification is based on a specific criteria (not decided yet). For example , If the sender wants to send the number "5" as a secret message , The algorithm could change 5 pixel values in the image which makes these 5 pixels have a unique value. and in the receiver part , the algorithm will calculate the number of modified pixels and identify the sender message.
