ABSTRACT:
A programmed computer for forming a pronounceable security password, includes storage medium having a plurality of first and second word segment portions stored thereon. Each second word segment portion is within one or more sets of second word segment portions, each set being associated with one first word segment portion. Each second word segment portion within a particular set is different from others within the set and is combinable with the associated first word segment portion to form a pronounceable word segment. A plurality of transition numbers each associated with one or more of the first word segment portions and corresponding to the number of said second word segment portions within the associate set of second word segment portions are also stored on the storage medium. The computer includes a processor programmed to select a first word segment portion and a second word segment portion from its associated set of second word segment portions. Selection of any one of the first word segment portions and any one of the second word segment portions within the associated set is of substantially equal probability. The processor combines the selected first and second word segment portions to form a first pronounceable word segment and determines if consecutive characters thereof are unacceptable based upon their correspondence to those of the first word segment portions having a transition number less than a threshold. If acceptable a pronounceable security password of eight or more characters is generated so as to include the first pronounceable word segment.
