Method for verification through dragging

The invention discloses a method for verification through dragging. The method comprises steps as follows: an identification tag with N identification areas is produced; terminal equipment is connected through special mark identification equipment; when the special mark identification equipment is contacted with the identification tag or the distance between the special mark identification equipment and the identification tag is within an identification distance range of the special mark identification equipment, the special mark identification equipment transmits acquired identification areas to a client; the client generates a detection mark as per a preset rule and generates a target mark randomly and simultaneously; the special mark identification equipment is dragged on the identification tag and transmits the acquired identification areas to the client, and the client modifies the position of the detection mark continuously as per the preset rule. With the adoption of the method, the complexity of software and hardware design is greatly reduced, development and maintenance costs of a whole system are greatly reduced, and the reliability of the system is improved.
