H.A.F Technique for Documents and Archaeologist Images Encryption

Abstract

The Encryption important Images like documents and archaeologist images area became extremely important now days , so that is why proposed new technique called H.A.F(Hind ,Ali and Farah) to encrypt image with complex steps to make it hard on hackers to hacked it , which need to reverse the block exchange then should be try to decrypt image by inverse math module use specific keys , these keys created using many probability with specific criteria . in this paper have twice keys with shifting blocks of images , in additional encryption method will apply on parts not the entire image . Experimental result and security analysis indicates the robustness and advantages of the new proposed algorithm. Technique is possible to reproduce the original image with no loss of information for the encryption and decryption process. It is fast and simple enough to be comparable to other recent methods, and it has passed all the security requirements and it is fast and secure to be used in very broad range of documents and archaeologist images encryption applications.
