System and method for communication service verification, and verification server thereof

A method for communication service verification, comprising:

• obtaining, by a user device, a light code from a light code transmission device;
• demodulating, by the user device, the light code to obtain a payload carried by the light code and encrypting the payload to generate a cipher;
• receiving, by a service system server, a service request from the user device;
• receiving, by a verifications server, a verification request from the service system server, wherein when the verification server receives the verification request from the service system server, the cipher is transmitted along with the service request to the service system server;
• and
• retrieving, by the verification server, a decryption key recorded in a verification table based on the verification request and decoding the cipher in the verification request using the decryption key to obtain a decoding result.

A verification server for performing decoding and verification for a communication service, the verification server comprising:

• a storage unit configured for storing a verification table related to a plurality of service system parameters of a plurality of service systems and decryption keys corresponding to the service system parameters;
• a request handling unit configured for receiving a verification request from a service system server or a user device, wherein the verification request includes a cipher and the service system parameters of the service system server, wherein a light code obtained by the user device is demodulated to obtain a payload carried by the light code and the payload is encrypted to generate the cipher, and wherein when the verification request is received from the service system server, the cipher is transmitted along with a service request from the user device to the service system server;
• and
• a signal decoding unit configured for retrieving the decryption keys corresponding to the service system parameters from the verification table, decoding the cipher using the decryption key to obtain a decoding result, and returning the decoding result via the request handling unit.
