Abstract

An RFID anti-counterfeit encrypted electronic tag is a wireless electronic tag attached to a product. An antenna is provided on a label substrate, and the antenna is electrically connected to an IC chip. The IC chip writes a UID identification code and encrypted NDEF public area data. The NDEF public area data is provided with a write password, and the read password is used to generate the read password; the electromagnetic wave is generated by the mobile device, the UID identification code is read, and the server connected to the Internet is used for comparison, and the authorization password is obtained when the comparison is successful Key, open the NDEF public area data, read the password, and then verify it by the server. The mobile device displays "genuine" when it is successful. Otherwise, it cannot determine the authorization key and judges "counterfeit" when the authorization is unsuccessful. The area data is encrypted, and the exclusive protection of the read password is generated by writing the password to achieve the anti-counterfeiting benefit of double authentication.

Description

RFID anti-counterfeit encrypted electronic tag

This creation is about an electronic tag, especially an RFID anti-counterfeit encrypted electronic tag, which uses the NDEF public area data encryption and the exclusive protection of the read password generated by writing a password to achieve the double authentication security benefits.

According to many industries today, radio frequency identification (RFID) technology is applied. This technology is a non-contact automatic identification system. It uses radio waves to transmit identification information, and a group of radio frequency identification The system consists of a tag and a reader. When the reader emits energy to the tag from a distance, the circuit on the tag can return a signal to exchange information with the reader.

RFID radio frequency identification technology has the characteristics of strong anti-interference, large data capacity of tags, dynamic operation, long service life, high security and fast recognition speed, so it is often used in some fields that need to collect or track information Including warehouse / transport / materials, access control / attendance, fixed asset management, train / car identification / baggage security inspection, medical information tracking, military / defense / national security and other industries.

However, the existing technology is conducive to managing goods and saving labor costs. However, some technologies have failed to effectively prevent and eliminate acts of piracy and counterfeit goods that have been rampant in recent years. Some unscrupulous people still use the labels on old products to replace Posing as a new product for sale; currently on the market The NFC standard specifications are generally written in the IC chip with the UID identification code (global unique code) and NDEF public area data (open data), the radio wave (13.56MHz; NFC protocol) is released through the mobile device's operating program APP, and read UID identification code to determine its authenticity. When being profiled, both the UID identification code and the NDEF public area data will be stolen. The stealer will use the profile copying method to reuse the well-known product labels that have been sold or to estimate the UID identification code that breaks the genuine product label. (Global unique code) and the logic principle of verification string, reuse the label in another product, counterfeit and sell it for the well-known product, etc. in order to make huge profits, this method is not only harmful to the guarantee of the quality of the original product Huge, and cause great damage to the goodwill of the label supplier and industry.

Therefore, in view of the problems existing in the above-mentioned conventional RFID electronic tags, how to develop a more secure and anti-theft RFID electronic tag, which is really eagerly expected by consumers, is also the goal and direction of relevant industry's efforts to develop breakthroughs. In view of this, the creators have been engaged in the manufacturing development and design of related products for many years. In view of the above goals, after detailed design and careful evaluation, the author can finally have a practical original creation.

That is, the main purpose of this creation is to provide an RFID anti-counterfeit encrypted electronic tag, which is a wireless electronic tag that can be attached to a product. The wireless electronic tag is attached to a label substrate and an antenna is provided. An IC chip is sexually connected. The IC chip has a UID identification code and an encrypted NDEF public area data, and the encrypted NDEF public area data is decrypted by obtaining a set of authorized keys from the outside. At least one write is set. The password, and use the write password to generate a read password; the overall structure uses a mobile device to generate electromagnetic waves, read the UID identification code of the wireless electronic tag, and connects to a server on the Internet for comparison, Match success When obtaining the set of authorization keys, open the NDEF public area data of the wireless electronic tag, read the read password, and hand it over to the server for verification. When the verification is successful, the mobile device displays as "genuine", and vice versa , The authorization key cannot be obtained, and it is judged as a “counterfeit” when the authorization is unsuccessful, the NDEF public area data of the IC chip of the wireless electronic tag is encrypted, and the encrypted NDEF public area data is written through the The password generates the exclusive protection of the read password to achieve the anti-counterfeiting benefit of double authentication.

The second purpose of this creation is to provide an RFID anti-counterfeit encrypted electronic tag. The encrypted NDEF public area data is provided with a fuse for the write password. When the write password is changed or modified a predetermined number of times, The fuse is cut by the energy of the radio wave, so that the content of the write password can no longer be written.

Next, in conjunction with the drawings and numbers, a preferred embodiment will be given for further explanation, so that your review committee can have a more detailed understanding of this creation.
