detailed description

The exemplary embodiments of the present invention are described with reference to the accompanying drawings, and are in the Therefore, it will be apparent to those skilled in the art that various modifications and changes may be made to the embodiments described herein without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The puzzle involved in the puzzle-based verification method and system according to the present invention divides a picture into N small pictures and scrambles the order of the small pictures, and then performs the correlation between each of the N small pictures. Restore to repeat the original picture. In accordance with In the puzzle-based verification method and system of the present invention, the picture for verification, that is, the divided picture is called “verification picture”, and the divided picture, so-called small picture, is called “segment picture”. ".

1 is a schematic block diagram of a puzzle-based verification system 10 in accordance with an embodiment of the present invention. As shown in FIG. 1, the puzzle-based verification system 10 includes: a picture cutting device 110 for cutting a verification picture into a plurality of divided pictures to obtain an original sequence of a plurality of divided pictures; and a picture encryption device 120 for The original sequence is randomly processed to obtain a random order of the plurality of divided pictures, and the random order is encrypted to obtain an encrypted random sequence; the communication device 130 is configured to send the verification picture, the plurality of divided pictures, and the encrypted random order Go to the user terminal and receive an arrangement order of the plurality of divided pictures submitted by the user; and the verification device 140 is configured to check whether the arrangement order of the plurality of divided pictures submitted by the user is the same as the original order of the plurality of divided pictures.

System 10 in accordance with an embodiment of the present invention, wherein the verification picture can be a picture of any shape, such as a rectangle, a circle, a trapezoid, an ellipse, a triangle, and the like. Wherein the picture cutting device may cut the verification picture into N divided pictures, where N is a positive integer greater than 1, and wherein each of the N divided pictures can have the same or different size and/or shape.
