The method includes: sending, by a first server, a two-dimensional code generation request to a second server, the request including information for generating a two-dimensional code; making, by the second server according to the received two-dimensional code generation request, a digital signature on the information for generating the two-dimensional code; sending the two-dimensional code information comprising the digital signature to the first server; and generating, by the first server, a two-dimen- sional code by using the two-dimensional code information. In embodiments according to the present invention, a two-dimensional code is generated by means of a synergistic effect between a server and another server, so that the security and effectiveness of the two-dimensional code are enhanced, and in a two-dimensional code recognition process, it is convenient to recognize whether the two- dimensional code is tampered.
