step S101, receiving service request information sent by a client, wherein the service request information carries a calculation result obtained by the client through calculation by using a preset algorithm according to the obtained calculation parameters;
and step S102, if the calculation result is judged to be correct, responding to the service request information.
Specifically, when the client sends the service request information to the server, the service request information needs to carry a calculation result obtained by the client performing calculation by using a preset algorithm according to the obtained calculation parameter. The calculation parameter may be a character string composed of characters, or may be other parameters such as a character. The preset algorithm can use an encryption algorithm or other algorithms, and different calculation results are output after different calculation parameters are input into the preset algorithm.
