Patient medical information in all forms is crucial to keep private and secure, particularly when data communication occurs through insecure channels. Therefore, there a bad need for protecting securing the color images against impostors invaders. In this paper, an optical image security approach introduced. It based on bit-plane Jigsaw Transform (JT) Fractional Fourier (FFT). Different kernels...

Secure environments protect the resources against unauthorized access by enforcing access control mechanisms. Therefore, when increasing security is an issue, text based passwords are not enough to counter such problems. Security has always been an issue since Internet and Web Development came into existence, numeric based passwords is not enough to counter such problems, which is also an out d...
