METHOD, DEVICE AND SYSTEM FOR IDENTIFYING ELECTRONIC PRODUCTS

摘要

The present invention provides a technical solution to identify an electronic product by means of the intrinsic physical character thereof, for the purpose of detecting fake products. The present invention provides a technical solution for obtaining the eigenvector of an operating electronic product by using a metal coil. The metal coil receives the electromagnetic wave emitted by the electronic product and converts it to an analog electrical signal, which analog electrical signal is then converted to a digital electrical signal, and then, the digital electrical signal is processed, in order to obtain a processed signal sequence as the eigenvector of said electronic product. On the basis of extracting the eigenvector, the present invention further provides a method, an identifying device and an identifying system for identifying an electronic product. A metal coil is used in the present invention, so that it is capable of detecting electromagnetic wave signals of a quite weak intensity, and the range of electronic products that can be identified using the characteristic information of the electromagnetic wave emitted by the electronic product is broadened effectively.
