Verification code verification method, device and equipment

Abstract

The invention discloses a verification code verification method and device and equipment. The method comprises the following steps: generating a verification code picture; according to the color information of the verification code picture, generating a verification passing color block; comparing the color blocks passing the verification, and generating interference color blocks different from the color blocks passing the verification; sending prompt rule information, the verification code picture, the verification passing color block and the interference color block to a client; receiving at least one target color block selected from the verified color block and the interference color block sent by the client; and verifying whether the target color block is the same as the color block passing verification, obtaining a verification result, and sending the verification result to the client. By means of the mode, the diversity of styles and display of the verification codes is achieved, and the cracking difficulty and the interaction frequency of the verification codes are increased.

Description

technical field [0001] The present invention relates to the technical field of verification codes, in particular to a verification code verification method, device and equipment. Background technique [0002] The verification code generated by the current technology has many manifestations, such as a random combination of numbers and letters, pictures containing specific text or specific elements, four arithmetic operations that randomly generate two elements, sliding verification codes, etc. The verification code elements in many input schemes are mostly numbers and letters. Under the background of random verification codes, the number of user operations in most schemes is relatively small, such as entering numbers and letters, or sliding the slider to a specific position once, resulting in The cost of machine processing is reduced; in addition, even if the verification code such as finding a specific object in a picture or selecting a picture containing an object increases...

Problems solved by technology

The verification code elements in many input schemes are mostly numbers and letters. Under the background of random verification codes, the number of user operations in most schemes is relatively small, such as entering numbers and letters, or sliding the slider to a specific position once, resulting in The cost of machine processing is reduced; in addition, even if the verification code such as finding a specific object in a picture or selecting a picture containing an object increases the number of user operations, due to the development of machine learning, target detection and recognition have been greatly improved. develop

Therefore, the existing verification code display form inevitably has the following problems: on the one hand, the verification code is easily recognized by the machine, resulting in being cracked, and cannot effectively prevent malicious behaviors such as automatic batch registration; on the other hand, each type of verification code is It is a specific format, such as digital verification is fixed-length, image verification is mostly based on matching principles, etc., resulting in a short user interaction process
