Embodiment Construction

[0023] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated.

[0024] figure 1 It is a schematic flow chart of a method for verifying a verification code in the present invention, including the following steps:

[0025] In step 101, when the server receives the verification request from the client, it returns M 3D model reference images and the unique identifier corresponding to each 3D model reference image to the client, where M is a positive integer greater than 0.

[0026] The 3D model reference graph is a graph obtained by performing 3D modeling on the item in 3D space. The items may be common items such as airplanes, vases, dogs, etc. in the real world. 3D modeling is to build models with 3D geometry and surfaces.

[0027] The unique identifier refers to the different numbers, letters, or combinations of numbers and letters assigned by the server to d...

Abstract

The invention discloses a method for verifying a verification code and a server. When a server side receives a verification request sent by a client side, M three-dimensional model reference pictures and the single corresponding identification are returned to the client side; when the server side selects N pictures from the three-dimensional model reference pictures, transformation is performed according to the spatial geometry transformation algorithm, the single identification of the N selected three-dimensional model reference pictures respectively serves as the single identification of transformed N ordered pictures; the transformed N ordered pictures are returned to the client side; the three-dimensional model reference pictures corresponding to the ordered pictures are selected, the single identification of the selected three-dimensional model reference pictures is led to serve as the verification code which is sent to the server side through the client side; and the verification code is compared with the single identification on the server side, and verification is passed if the verification code coincides with the single identification. By aid of the method and the server, decoding resistance of the verification code is improved, the verification code can be recognized by human eyes easily, and both safety and availability are considered.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to a method and server for verifying verification codes. Background technique [0002] Exchanging information with servers through computer networks has become the most common way for people to obtain information services in their daily lives and work. A large number of network services provide online interactive services for individual users. The verification code technology is to prevent hackers from using malicious programs to automatically register and log in, launch malicious flooding, maliciously increase database access, and steal confidential information and other attacks. [0003] The verification code technology is currently represented by a two-dimensional graphic verification code. A two-dimensional graphic verification code is a two-dimensional picture containing characters generated by the server. The characters in this picture are usually distorted or distort...
