CHARACTER-ENCRYPTING METHOD, AND ENCRYPTED-CHARACTER-CODE DEPICTING METHOD AND PROGRAM

摘要

A first computer determines a position of character distnctive data extracted from glyph data of characters to be encrypted in accordance with a second parameter value obtained by the generation of a plurality of quasi-random numbers and transfers the character distnctive data obtained from the glyph data at this position to encrypted character codes. When a second computer displays the encrypted character codes, the second computer retrieves encrypted character codes in a decoding table obtained from the first computer and glyph data for encryption depicted from the second parameter. Data including encrypted character codes as glyph data to be depicted at a position instructed by the second parameter from the glyph data are extracted and depicted.
