Description

Anti-counterfeiting electronic device, anti-counterfeiting system and anti-counterfeiting method Technical Field The invention relates to the field of anti-counterfeiting, in particular to an anti-counterfeiting electronic device, an anti-counterfeiting system and an anti-counterfeiting method. Background The fake goods and the counterfeit goods bring huge economic losses to legal brands and seriously infringe the legal interests of consumers. Although many new security technologies have emerged in the market over the last decades, attempts have been made to deter others from counterfeiting by, for example, creating certain special security features on the merchandise, including special inks, special materials, special printing processes, etc., by keeping these special processes secret. But it proves that theft or imitation of counterfeiters cannot be prevented at all by confidentiality. The prior anti-counterfeiting technology realizes the identification of the authenticity of the commodity by means of the mode of 'naked eye observation and human brain judgment' of a consumer, and in fact, common consumers hardly learn and master the anti-counterfeiting knowledge of different commodities in five flowers and eight doors, and the visual resolution of the anti-counterfeiting technology also hardly reaches the level of being capable of identifying counterfeit products which are sufficiently spurious. Since various anti-counterfeiting marks are easy to imitate, many brands only need to stack a plurality of different anti-counterfeiting means (commonly called as comprehensive anti-counterfeiting) on one commodity to increase the difficulty of imitation, but the consumers are certainly required to have knowledge and skills of sensory recognition of multiple anti-counterfeiting technologies of the purchased commodity, and most consumers cannot have the complicated anti-counterfeiting knowledge and skills at all, so that the comprehensive anti-counterfeiting becomes an ineffective furnishing. In addition, with the high popularization of image scanning and printing equipment, the two-dimensional code traceability tag can be easily copied by anyone. The fake goods found in the market are mostly printed with the traceability two-dimension codes consistent with the genuine goods, so that the two-dimension code traceability labels gradually lose the trust of consumers. The prior RFID chip anti-counterfeiting technology adopts a mode of storing a series of numbers, but the RFID chip is easy to clone and copy and does not have anti-counterfeiting capability, and the RFID chip with encryption operation or anti-counterfeiting capability has high manufacturing cost because of containing a CPU, and is difficult to popularize in the field of common commodity anti-counterfeiting. Of course, two-line anti-counterfeiting technology is also adopted to perform anti-counterfeiting, and the two-line anti-counterfeiting technology refers to anti-counterfeiting technology which needs to be authenticated by means of professional experimental equipment, and the technology increases small difficulty for counterfeiters, but the consumers cannot equip the professional equipment, and the authentication experiment cost is high, so that effective protection cannot be implemented for vast consumers. For a long time, the anti-counterfeiting industry and academia have been diligent in an attempt to solve the problem of poor anti-counterfeiting effect, but the anti-counterfeiting technology has not broken through the ubiquitous dilemma up to now due to the high difficulty, high complexity and challenges of the anti-counterfeiting technology as a worldwide problem. Disclosure of Invention The invention mainly aims to provide an anti-counterfeiting electronic device, an anti-counterfeiting system and an anti-counterfeiting method, which aim to improve the anti-counterfeiting accuracy and the convenience of a user for determining an object to be inspected by using an anti-counterfeiting technology. In order to achieve the above object, the anti-counterfeiting electronic device provided by the invention is used for determining the source of an object with a rough surface, and comprises a storage module, a communication module and a processing module, wherein: the storage module is used for storing the reflection image set of the rough surface of the registered object Wherein the set of reflected imagesThe image acquisition device is used for acquiring at least three beams of light from the rough surfaces of a plurality of registered objectsCorresponding reflection image under irradiationThe communication module is used for receiving the current light of the surface of the object to be testedReflection image under irradiationA processing module for calculating the reflected imageIs a gray scale map of at least one designated fixed region of (1)Or a gradient mapWherein the processing module is further configured to calculate the current lightThe reflect
