PROBLEM TO BE SOLVED: To remove interruption by a third party and invasion of false information and to improve a line load and communication speed by converting certification data of picture information into a binary signal, transmitting it, restoring picture information restored on a reception side into original certification data with operated data for automatic error correction and specifying a transmitter based on customer recognition picture information and correction data. SOLUTION: The certification data read part 21 of a first computer 1 reads certification data recording paper where display by a two-dimensional code is recorded as certification data and generates certification data N1 as picture data in a memory. Certification data N1 is sent to a certification data thresholding part 22 and it is converted into a binary signal. Then, certification data N2 is generated and it is sent to a second computer 2 with the operation of the certification key 24 of a ten key input part 23. In the second computer 2, certification data N2 is converted in a two-dimensional encoding part 12 and certification data N1 is obtained. Data distortion is corrected with error correction technology and reception data is specified in a comparison part 14. |
