Abstract: By using certain natural sources as data input, absolute randomness can be reached. This invention focuses on the use of randomly captured photograph from one natural source (Wind Movements) as one working process example, to generate absolutely random, scalable (0, 1)-bit-string as high-safety encryption key. This invention's absolute random and automatic encryption can be best used for all digital data communications, and for digital devices privacy. Additionally, this invention provides one specific asymmetric encoding rule, which enables solid implementation of encryption by using the absolute randomly generated encryption key so that any digital data on any digital device can be very safely encrypted.
