Optical scanning cryptography

T.-C. Poon is developing an on-the-fly optical encryption system for secure wireless transmission. The proposed technology could use standard laser scanners to encrypt documents and images and automatically transmit the data securely. Without the right decryption key, a receiver would see only digital noise.
