The invention discloses an intelligent image verification method and an intelligent image verification system. The system comprises a data receiving module, an image code generating and verifying module, a timer module, an image data generating module, a database module, an image verification module and a data transmitting module. The data receiving module is used for receiving access requests, image verification code input and image selection sequence of a client user, the image code generating and verifying module is used for generating and verifying image verification codes, the timer module is used for performing timing and aging limiting for client access, the image data generating module is used for randomly generating prompting codes and corresponding N images, the database module is used for performing storage and index access for processing keywords, the prompting codes and image filenames, the image verification module is used for comparing the received image selection sequence of the client user with the image sequence generated by the image data generating module, and the data transmitting module is used for transmitting the image verification codes, the prompting codes, the N images and verification results to the client user, wherein the prompting codes and the N images are generated during image verification. By the aid of the intelligent image verification method and the intelligent image verification system, contradiction between usability and safety of an existing system is solved, whether the client user is a machine or not can be automatically identified, and network safety is improved.
