Problems solved by technology

For example, an electronic seal usually includes a serial number and a date. In some applications, each time an electronic seal is affixed, the serial number needs to be increased, and the date in the electronic seal will also change with the stamping date. Changes, for this kind of electronic seal, it is difficult to use the traditional method of making seals

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] In the present invention, the part of the electronic seal that does not need to be adjusted can be regarded as the static unit of the electronic seal, and various parameters that need to be adjusted, such as number, date, time, etc., can be regarded as the dynamic unit.

[0035] Figure 1A It is a schematic diagram of a complete image of an electronic seal, Figure 1B It is a schematic diagram of the static unit of the stamp (that is, the constant part in the stamp display, which does not change with the external environment and operation method), and the dynamic unit of the stamp (that is, the part that often needs to be changed and adjusted in the stamp display) is Such as Figure 1A The number and date in the electronic seal shown in , the number in the seal will automatically increase by 1 each time the seal is stamped, for...

Abstract

The invention discloses a realizing method for a dynamic electronic stamp. The method comprises the following steps: manufacturing a stamping mold of a static unit of the stamp; and determining that a dynamic unit of the stamp is formed by which parameters and determining attribute of each parameter. Through respectively manufacturing an unchanged part which is the static unit and a changeable part which is the dynamic unit in the stamp and then combining the two parts, the method can conveniently manufacture the electronic stamp containing dynamic information.

Description

technical field [0001] The invention relates to electronic seal technology, in particular to a method for realizing a dynamic electronic seal. Background technique [0002] Electronic seal technology uses digital technology to simulate traditional physical seals. Its management and use methods conform to the habits of physical seals. The electronic documents stamped by it have the same appearance, same effectiveness and similar usage as paper documents stamped with physical seals. . [0003] The making of traditional electronic seals is usually achieved by making stamp pictures of the seal. The impression image of the created stamp is saved as stamp data, for example, it can be saved in a specific peripheral device such as a USB flash drive. In order to ensure that the seal data will not be modified at will, it is usually necessary to perform security processing on the seal data such as signature protection. [0004] However, for the situation that the electronic seal nee...
