The writing module 30 writes the characteristic information into the banknote chip side when receiving the confirmed writing request returned by the banknote chip side first communication module 50. When the public key decryption module 40 at the banknote chip side successfully decrypts the public key corresponding to the authorized private key, the first communication module 50 at the banknote chip side sends a write confirmation request to the client write-in module 30, and after the write-in module 30 receives the write confirmation request returned by the banknote chip side based on the encrypted characteristic information of the client private key, the characteristic information is written into the banknote chip side, that is, the write-in module 30 sends the characteristic information to the public key encryption module 60 at the banknote chip side. Namely, the public key corresponding to the authorized private key is used for successful decryption, namely, after the client is confirmed to be an authorized true client, the writing module 30 is allowed to write the characteristic information into the banknote chip.
When the write module 30 receives the write rejection request returned by the first communication module 50 at the banknote chip side, the characteristic information is not written into the banknote chip side. When the banknote chip side public key decryption module 40 fails to decrypt with the public key corresponding to the authorized private key, the banknote chip side first communication module 50 sends a write-refusal request to the client side write-in module 30, and after the write-in module 30 receives the write-refusal request returned by the banknote chip side based on the client side private key encrypted feature information, the feature information is not allowed to be written into the banknote chip side. Namely, the decryption by using the public key corresponding to the authorized private key fails, namely, after the client is confirmed to be a fake client, the client is not allowed to write the characteristic information into the banknote chip.
Referring to fig. 5, fig. 5 is a schematic diagram of a module relationship of a banknote chip end for reading and writing banknote characteristic information according to a second embodiment of the present invention.

After confirming that the current client is an official authorized client, a confirmation write request is sent to the client write module 30.
When the first communication module 50 receives the information that the decryption is not successful, it indicates that the public key corresponding to the private key of the client authorized by the authority is not paired with the private key of the client used for encryption, which proves that the current client is a forged client. After confirming that the current client is a fake client, a write-reject request is sent to the client write module 30.
The public key encryption module 60 is connected to the second communication module 70. The public key encryption module 60 obtains the server public key after receiving the characteristic information sent by the write-in module 30, and encrypts the characteristic information by using the server public key to generate public key encrypted characteristic information. The public key encryption module 60 obtains the server public key from the server after receiving the feature information, encrypts the received feature information using the server public key, and generates encrypted public key encrypted feature information. The public key encryption module 60 transmits the generated public key encryption feature information to the second communication module 70. That is, all information contents of the banknote chip end and the server end need to be encrypted by using the public key of the server when information interaction is carried out, and when the banknote chip end sends the characteristic information to the server end, the characteristic information needs to be encrypted, so that the transmission of the characteristic information is carried out under the condition that the safety of the characteristic information is ensured.
