Intelligent seal and authentication method

Abstract

The invention provides an intelligent seal, and belongs to the technical field of office supplies. The intelligent seal comprises a bottom box, a movable seat and a locking assembly; the bottom box is a hollow cylinder with an open end; the movable seat is arranged in the bottom box and is movably connected with the bottom of the bottom box through a spring; and the locking assembly is arranged on the movable seat, the locking assembly comprises a spring bolt, the locking assembly can control the spring bolt to stretch out or retract, a lock hole is formed in the bottom box, and the spring bolt can be inserted into the lock hole. By means of the intelligent seal, a control module can control the spring bolt to retract through an authentication instruction input through Bluetooth, a network or other modes, at the moment, a user can normally use the seal, the seal use frequency is judged through pressure data input by a pressure sensor, and after the authorized seal use frequency is reached, the spring bolt stretches out, and the seal is locked again.

Description

technical field [0001] The invention relates to the technical field of office supplies, in particular to an intelligent seal and an authentication method. Background technique [0002] The seal is used as a stationery printed on the document to indicate identification or signature. The seal can be printed on the text to indicate the act of signing. The existing traditional seal holder can use the seal without restriction. For the owner of the seal, It is not convenient for the seal owner to manage and control the use of the seal. [0003] In addition, according to the survey, when some users print the seal on the paper, in most cases, the direction of force cannot be completely perpendicular to the paper. There is an included angle of 0.5-3° on the surface. In this case, the seal pattern cannot be completely printed on the paper, resulting in the failure of the seal to sign the document.

[0003] In addition, according to the survey, when some users print the seal on the paper, in most cases, the direction of force cannot be completely perpendicular to the paper. There is an included angle of 0.5-3° on the surface. In this case, the seal pattern cannot be completely printed on the paper, resulting in the failure of the seal to sign the document.

[0004] When the documents are stacked together and stamped, the corners of other papers are placed on the stamp, and the height difference prevents the stamp pattern from being printed in the area near the corners. The above situation will also cause the signature of the document to be invalid.
