Ultrasonic wave anti-fake device and method

Abstract

The invention discloses an ultrasonic wave anti-fake device and method. The device comprises an anti-fake module and a verification module, the anti-fake module and an object needing anti-fake processing are packaged together, and the anti-fake module comprises a first acoustic wave receiver, a first acoustic wave generator and a first processing unit, wherein the first acoustic wave receiver is used for monitoring external pairing ultrasonic wave signals, the first acoustic wave generator is used for transmitting encryption signals containing object information, and the first processing unit is used for analyzing and processing the pairing ultrasonic wave signals and generating the encryption signals. The verification module comprises a second acoustic wave generator, a second acoustic wave receiver, a second processing unit and a displaying unit, wherein the second acoustic wave generator is used for generating pairing ultrasonic wave signals, the second acoustic wave receiver is used for receiving encryption signals, the second processing unit is used for generating pairing ultrasonic wave signals and decrypting the encryption signals, and the displaying unit is used for displaying the object information obtained through decrypting the encryption signals. When the information of the object needing anti-fake processing needs to be inquired, the verification module generates the pairing ultrasonic wave signals, the anti-fake module generates the encryption signals when monitoring that the pairing ultrasonic wave signals are matched with stored secrete keys, and the verification module receives and decrypts the encryption signals according to a conventional algorithm and displays the decrypted information on the displaying unit.

Description

technical field [0001] The invention relates to an anti-counterfeiting device based on ultrasonic technology and an anti-counterfeiting method thereof. Background technique [0002] With the improvement of people's living standards, more and more attention is paid to brand consumption, and because brands are becoming more and more important, unscrupulous businesses can obtain greater profits by counterfeiting well-known brands, and it also seriously affects consumers' confidence in well-known brands. All kinds of anti-counterfeiting means are to refuse counterfeiting and protect the brand. The development of anti-counterfeiting technology is closely related to the development of other related disciplines and technologies. While incorporating advanced technological achievements, it has also become the crystallization of the combination and comprehensive application of multidisciplinary scientific and technological achievements. Now there are more and more companies specializ...

Problems solved by technology

[0003]At present, the commonly used anti-counterfeiting methods include code anti-counterfeiting, RFID anti-counterfeiting, laser anti-counterfeiting, etc. The code anti-counterfeiting labels are easy to be counterfeited by criminals, and RFID anti-counterfeiting is a kind of High-tech anti-counterfeiting means, but this anti-counterfeiting means is currently difficult to be widely used in the market, because the high investment cost of RFID anti-counterfeiting makes it difficult for some small and medium-sized enterprises to accept

Laser anti-counterfeiting labels are made by laser coding machines. The cost of laser coding machines is very high, and it is difficult for ordinary small and medium-sized enterprises to adopt them.

Laser holographic anti-counterfeiting is very effective, but if the criminals get the laser coding machine, then all the laser holographic anti-counterfeiting labels will be indistinguishable, they are all real, and the anti-counterfeiting effect will disappear instantly
