Abstract
An identification sequence issuing device comprising a code converter portion for converting an identification sequence character string that may include letters, numerals, and the like, into a string of character codes having one-to-one correspondence to the characters in the character string, and a check and selection portion for selecting as an identification sequence the character string corresponding to a character code string that is determined to meet a Reed-Solomon code rule with each character code being a symbol of the Reed-Solomon code and the character code string length being the length of the Reed-Solomon code. The identification sequence is issued based on the Reed-Solomon code of a generating polynomial having a plurality of initial elements as roots, and for additional issuing, identification sequences are issued based on the Reed-Solomon code with the number of roots of the generating polynomial reduced by 1.
