Long-life anti-counterfeiting method

Abstract

The invention discloses a long-life anti-counterfeiting method, which comprises an anti-counterfeiting establishment step and an anti-counterfeiting detection step, wherein the anti-counterfeiting establishment step comprises: preparing at least one of SAW (surface acoustic wave) devices and microwave ceramic devices, storing the data of the device, and fixing the device with a product or product packing together; and the anti-counterfeiting detection step comprises: sending a testing wave to the product or product packing to obtain and record a feedback wave, and judging when the feedback wave is corresponding to the stored data, if so, determining that the product is a genuine product, otherwise, determining that the product is a counterfeiting product. The applicant cleverly applies SAW devices and microwave ceramic devices to the anti-counterfeiting method, and through using the characteristics (such as complicated and diversified waveforms, long life and high temperature resistance) of the devices, the following technical effects are generated: the anti-counterfeiting effect is good, and the anti-counterfeiting period is long even up to hundreds or thousands of years, and the like; and the device is high-temperature-resistant, and can be embedded into products or product packing through sinter molding.

Description

technical field [0001] The invention relates to a long-life anti-counterfeiting method. Background technique [0002] China Patent Database 200910040577.4 published the application for the invention of "Intelligent Anti-counterfeiting Bottle Stopper". It uses RFID radio frequency tag technology. RFID radio frequency tags have many advantages, making it more and more common for anti-counterfeiting. However, due to the low temperature resistance and shock resistance of semiconductor circuits Because of poor movement and corrosion, easy decryption of information, and reliable life of no more than 10 years, it is prone to huge defects such as embedding (cannot be embedded in most products) and short life, making it generally only used for short-term circulation thing. However, high-value ceramics, glass, sculptures, calligraphy and paintings and other works of art and high-end alcohol products with long-term preservation value must face anti-counterfeiting requirements for tens...

However, high-value ceramics, glass, sculptures, calligraphy and paintings and other works of art and high-end alcohol products with long-term preservation value must face anti-counterfeiting requirements for tens, hundreds, or even thousands of years. Previous anti-counterfeiting methods were not available. This ability, the use of artificial identification is unreliable or must be opened to destroy
