Problems solved by technology
[0004] 1. When judging whether the verification is successful, it is necessary to analyze and compare the picture with the image of the verification code, which is very computationally intensive and time-consuming;
[0005] 2. Unlike text, numbers, etc., pictures and images cannot be randomly generated, and pre-prepared pictures need to be used, and the pre-prepared pictures are limited, so the verification codes obtained are also limited. If you collect verification codes for all pictures method, it is still possible to verify through the verification method of enumerating all image verification codes by the machine

The invention provides a verification method and apparatus for a picture verification code. The method comprises: selecting a picture from a preset picture library, and generating a verification code according to the picture, wherein the verification code is variable in form and forms the picture in a specific form; receiving a verification operation of a user, and changing the form of the verification code according to the verification operation; selecting a first region from a modified verification code and extracting image information of the first region; selecting a second region in the picture and extracting image information of the second region, wherein the position of the second region on the picture corresponds to the position of the first region on the verification code; and comparing the image information of the first region with the image information of the second region, and judging whether the verification operation is successful or not according to a result. According to the verification method and apparatus, images of partial regions corresponding in position are extracted and compared, and the extracted image information is reduced, so that the comparison efficiency of the extracted image information is improved and whether the verification is successful or not can be quickly judged.
Description
technical field [0001] The present invention relates to the field of Internet technologies, and in particular, to a method and device for verifying a picture verification code. Background technique [0002] At present, the application of verification code is relatively common. It is used to distinguish users from computers and people, and can effectively prevent the occurrence of malicious password cracking, ticket swiping, and forum flooding. [0003] One type of verification code is a picture verification code, which is formed by cutting and deforming a picture, and requires the user to restore the verification code to the original picture by splicing and other operations on the verification code. The advantage of this verification code is that the images in the picture are richer, and it is more difficult to be recognized by machines than words and numbers, but this verification code also has certain defects: [0004] 1. When judging whether the verification is successfu...
