In the computer data security field, a cryptographic hash function process embodied in a computer system and which is typically keyless, but is highly secure. The process is based on the type of randomness exhibited by well known tetromino stacking games. Computation of the hash value (digest) is the result of executing such a“piling on”(tetromino stacking game) algorithm using the message as an input (a seed) to a pseudo random number generator which generates the game pieces (shapes) from the resulting random numbers, then executing the game algorithm.
