Title:
CHARACTER-ENCRYPTING METHOD, AND ENCRYPTED-CHARACTER-CODE DEPICTING METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2007/091336
Kind Code:
A1
Abstract:
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.
