Optical encryption and decryption /
This Spotlight introduces some classical information-security approaches, e.g., steganography, watermarking, and digital cryptographic methods. It provides an overview of optical encryption from the perspective of image (both 2-D and 3-D) and optical-information processing. Both experimental and syn...
