Random Number Generated from White Noise of Webcam

Random number generators play a very import role in modern cryptography, especially in personal information security. For example, to generate random number from white noise of webcam is a new approach for personal device. Through our algorithms, 91% IPcam generating sequences pass at least four statistical tests, 87% pass all five ones has been approved. Compared with webcam and video respectively, on the contrary, the possibility for both generating sequences to pass all five statistical tests is roughly 80%. The result implies improvement by algorithm on personal devices such as laptop, for instance, is necessary to generate qualified random number to protect private information.
