Abstract

The embodiment of the invention provides a generation and verification method and device of a verification code picture. The generation method comprises the following steps: selecting a plurality of first elements and a plurality of second elements, wherein there is a preset association relationship between each first element in the plurality of first elements and at least one second element in the plurality of second elements; determining a picture to be synthesized, and determining the positions of each first element and each second element in the picture to be synthesized; and synthesizing the plurality of first elements and the plurality of second elements to the picture to be synthesized according to the positions of each first element and each second element, and obtaining the verification code picture. The generation method of the verification code picture provided by the invention solves the problem that the prior art cannot effectively prevent a machine program from recognizing a verification code.

Description

Technical field [0001] The present invention relates to the technical field of information security, in particular to a method and device for generating and verifying a verification code picture. Background technique [0002] The verification code technology can distinguish whether the access operation is performed by a real and effective user, or whether it is automatically simulated by a machine program. Most of the verification codes currently in use are composed of numbers, letters or text. Such verification codes often add interference to prevent automatic recognition by machine programs. However, if too many interference factors are added, the recognition rate of the human eye will decrease and increase users. It is difficult to recognize the input, and this type of verification code can already be automatically recognized by the machine program. [0003] Aiming at the problem that the prior art cannot prevent automatic recognition by a machine program when the verification ...
