Popis: We propose a method for information security technique using computer generated holographic image processing. Using encryption key factors, computer generated holographic image and Fourier plane phase mask, an image or document to be secured is encrypted by digital holographic image encoding processor. The proposed image encryption technique can also be used for wireless application in real-time. For the use of real-time wireless application, the encrypted information is required to be stored as electrical signal. For reconstruction of the encrypted image in secure site, the encrypted image is, together with a decryption key, processed and sent to a decryption processor unit. If the encryption key and decryption key are matched, the decryption unit will decrypt the image. We present computer simulation of the idea.
