Embodiment Construction
[0027] like figure 2 As shown, the digital digest generating device 2 according to the first embodiment of the present invention includes an original information converter 21 and a digital digest calculator 22 . The original information converter 21 performs simple function processing on the input original information S, such as front-to-back swap, first odd digits and then even digits, shifting characters up by one, etc., to obtain transformed information S'. For example, assuming S=abcdefghijklmn, if the original information converter 21 performs the processing of the original information before and after swapping, then the obtained S'=nmlkjihgfedcba; , then the obtained S'=acegikmbdfhjln; if the original information converter 21 performs the process of shifting the character up by one on the original information, the obtained S'=bcdefghijklmno.
[0028] The original information converter 21 inputs the converted information S' into the digital digest calculator 22. The di...
