Abstract

The invention provides a method and a device for preventing copying of a miniature induction chip, wherein the method can effectively prevent adverse copying of information in an IC chip. The method comprises the steps of receiving an input decryption password, determining whether the input decryption password matches a latest password which is transmitted to the IC chip in last accessing of a server; if matching fails, adding one to the number of password matching error times; and if the number of password matching error times is larger than a preset threshold, making the IC chip enter a self-closed state or automatically clearing information in the IC chip. The invention relates to the field of bird ring application.

Description

technical field [0001] The invention relates to the application field of bird rings, in particular to a method and device for preventing duplication of micro induction chips. Background technique [0002] In recent years, an integrated circuit (Integrated Circuit, IC) chip refers to a chip made by placing an integrated circuit formed by a large number of microelectronic components (such as transistors, resistors, capacitors, etc.) on a plastic base. [0003] An integrated circuit is a tiny electronic device or component. Using a certain process, the transistors, diodes, resistors, capacitors, inductors and other components required in a circuit are interconnected together, fabricated on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a tube. Inside the shell, it becomes a microstructure with the required circuit functions; all the components in it have been structurally integrated, making electronic components a big step towards ...
