Man-machine identification method based on sliding puzzle verification code

Abstract

The invention belongs to the field of user identification of computer information security, and relates to a man-machine identification method based on a sliding puzzle verification code. The method comprises the following steps: a client requests a server base map and a sliding block; the server generates a base map, a sliding block and a unique identification code and returns the base map, the sliding block and the unique identification code to the client; the client generates a verification code UI according to the base map and the sliding block; the client collects the displacement of theuser moving sliding block; the client encrypts the collected data and the unique identification code and sends the encrypted data and the unique identification code to the server; the server decryptsthe encrypted data of the client; and the server authenticates the man-machine and returns an authentication result. The method is distinguished from a traditional image-text verification code, so that a code printing recognition black industry tool is out of action, and a certain confrontation protection effect is achieved; meanwhile, the user does not need to identify graphic and text information and related typing operations, and only needs to drag the sliding block to finish picture splicing to finish verification, so that the user operation is simplified, and the user experience is optimized.

Description

technical field [0001] The invention belongs to the field of user identification of computer information security, and relates to a human-machine identification method based on a sliding puzzle verification code. Background technique [0002] In the current network environment, there are many mature tools for coding and cracking black production of traditional graphic and text verification codes. In the face of increasingly severe network security environment, traditional graphic and text verification codes are no longer enough to provide security. As a human-computer authentication technology, the sliding puzzle verification code increases the difficulty of machine brute force cracking in terms of interactive operation; in terms of user experience, it is easy to understand and simplifies user operations, which satisfies the requirements of the current network environment for human-machine authentication. Security requirements, and improve the authentication efficiency and e...
