Abstract: A technique for secured personal identification numbers which cannot be readily detected by either observation or repeated trial attempts is disclosed. The secured personal identification number maintains the dual level security of a personal identification number or password without adding substantial complexity or an undesirable reduction in security. Moreover, the secured personal identification number of the present invention is readily applicable to any type of account which is accessed by entry of an account number and a personal identification number or password.

Abstract: A Mnemonic Number Dialing Plan is offered, having a telephone keyset which can be used in regions where the written language is based on a large number of characters or symbols. Selected phonetic characters of the known phonic character set are identified with the various numerical keys of the keypad in a relatively flexible association allowing adaptability to a number of different phonic character sets of varying size. The mnemonic to be translated into a telephone number preferably consists of a phrase, where the number of words corresponds with the number of digits in the telephone number, and only the first phonic sound of a word in the mnemonic phrase is used in mnemonic dialing.
