Method and system for preventing third party from accessing server resources

The invention discloses a method and system for preventing a third party from accessing server resources, and belongs to the technical field of network security. A client and a server appoint a specific encryption algorithm and an encryption factor, and appoint a private protocol for data disruption; when a client requests background resources, variable verification information is added to a self-defined Header, the verification information comprises the private protocol, and encryption is carried out by using an encryption algorithm; the server side intercepts a client side request, verifies and decrypts the verification information, after verification succeeds, the decrypted verification information is encrypted and then stored in a background database, a life cycle is set for the verification information and used for uniqueness judgment of the verification information, and when the same verification information is used for requesting resources, the verification failure is caused by the uniqueness judgment
