Abstract

The invention relates to an outer-ring-rotatable official seal and an encryption method thereof. The outer-ring-rotatable official seal comprises a shell and a base, a groove is arranged in the bottom of the shell, the base is inserted in the groove, the top of the base is fastened and connected to the shell through a screw, a cavity is formed between the groove and the base, an electric drive mechanism is arranged in the cavity, and the bottom of the electric drive mechanism is provided with a rotary mechanism; the bottom of the shell is provided with an outer ring around the outside of the base, and the rotating mechanism penetrates the bottom of the base to be connected with the outer ring; serial code marks are arranged between the inner edge of the bottom of the outer ring and the outer edge of the bottom of the base. The outer-ring-rotatable official seal has the advantages that the official seal has encryption effect, cannot be counterfeited at will, can rotate by a certain angle according to partial content of a file to generate different encrypted data, can be directly stamped on the file, can be prevented from being printed privately and duplicated, and can be effectively bound with the file to prevent the file from being falsified.

Description

technical field [0001] The invention relates to the application field of official seals, in particular to an official seal with a rotatable outer ring and an encryption method thereof. Background technique [0002] Most of the official seals currently used by people have uniform standards in appearance, while the pattern part is anti-counterfeiting, and is an important signature certificate for business transactions of various units. Most of the existing official seals still use the original method, but due to the small size of the official seal, easy to carry, and lack of fixed protection measures, some bad human factors can easily intervene in the use of the official seal, and the seal is easy to be damaged. Imitation has certain restrictions on the protection of paper documents and the official seal itself. Therefore, the safe and reasonable use of the official seal can only rely on the monitoring of the person in charge and the consciousness of the user. In reality, th...
