The real risk in the privacy of a plain image transmitted over an unsecured connection is content alteration or illegal eavesdropping. The architecture proposed in this paper provides Encryption and Authentication (EA) in their comprehensively for protecting a transmitted image from unauthorized with an average execution time of one second for each 256*256 color image. At the origin point (sender side), it encrypts and signs the image’s content. On the receiver side, it decrypts and verifies the cipher image, achieving two stages of confidentiality and two stages of verification for the image content without depending upon any third party and reinforced with two key chaos equal size color images. Every image has a unique hash value (signature or identity) with QR Code watermarking used to detect forgeries, even if the change is slight (even by one bit). EA has features that make it more resistant to security attacks, as shown by the experiments in this paper.
