NETWORK SYSTEM, DATA ERROR VERIFICATION METHOD, INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, INFORMATION PROCESSING PROGRAM, AND COMMUNICATION TERMINAL

摘要

PROBLEM TO BE SOLVED: To verify an error in communication data by simple processing.SOLUTION: A network system includes a communication terminal and an information processing apparatus. The communication terminal includes storage means for storing transmitted data which has been transmitted to the information processing apparatus. The information processing apparatus includes first message transmission means which transmits a first massage including receiving data which has been received from the communication terminal, to the communication terminal. The communication terminal includes: first message receiving means for receiving the first message; comparison means which extracts the receiving data from the first message, to be compared with the transmitted data; and second message transmission means which transmits a second message including a comparison result of the comparison means. The information processing apparatus includes: second message receiving means for receiving the second message; and error verification means which verifies an error in the receiving data, on the basis of the comparison result included in the second message.SELECTED DRAWING: Figure 1
