Anti-fake seal and read-write method thereof

Abstract

The invention discloses an anti-counterfeiting seal and a read-write method thereof. The anti-counterfeiting seal comprises an anti-counterfeiting seal body, a seal surface which is fixedly connected with the anti-counterfeiting seal body, an electronic tag and a holding part which is used for placing the electronic tag. The write-in method of the seal information of the anti-counterfeiting seal includes the following steps: a reader tests whether the writing code of the electronic tag is a correct writing code; if the writing code is correct, the seal information is written in the electronic tag. The read-out method of the seal information of the anti-counterfeiting seal includes the following steps: the reader tests whether the read key of the electronic tag is a correct read key; if the read key is correct, the seal information of the electronic tag is read. The electronic tag of the anti-counterfeiting seal of the invention stores the seal information, and does not need to depend on the networking database to inquire the relevant seal information. Besides, the electronic tag in the anti-counterfeiting seal is encrypted, which can basically block various possibilities of forgery and counterfeiting.

Description

technical field [0001] The invention relates to an electronic anti-counterfeiting technology, in particular to an anti-counterfeiting seal and a reading and writing method thereof. Background technique [0002] With the rapid development of electronic technology, the item electronic label system has been relatively mature. However, as a seal widely used in China, the relevant technology is still in a relatively primitive state. Due to the development of photocopying and scanning technology, the copying technology of chapter face is getting higher and higher, and the cost is getting lower and lower, resulting in the flood of fake chapters. In terms of management, use, and social recognition, it is necessary to put encrypted electronic tags into the seal. [0003] An existing anti-counterfeiting seal is to insert a numbering chip into the seal, and connect with a database through the numbering to achieve the functions of inquiry and identification. But this method has certa...

Problems solved by technology

But this method has certain limitations. First, it is easy to copy, and the number cannot be encrypted. A third person can copy the exact same number chip after reading the code through a hidden device. Second, it is easy to forge, and the number chip is easy to obtain. Three people using counterfeit number chips can also be recorded into the database. Third, the number itself does not contain any information, and all information depends on the database. However, the police or relevant departments may not be able to connect to the database anytime, anywhere when checking.

[0004] This shows that the above-mentioned existing anti-counterfeit seal and its reading and writing methods obviously still have inconvenience and defects in structure and use, and need to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
