 Use Case 1:
 
 Use Case 2: 
-In order for both parties to agree on the position of the data using Diffie Hellmann , An algorithm must be implemented. 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 one color image and in the receiver part , the algorithm will calculate the number of modified pixels.
