Identity recognition method based on time sequence spectrum

Abstract

The invention provides an identity recognition method based on a time sequence spectrum, and belongs to the technical field of identity recognition, and the method comprises the following steps: a cipherer collects whether an input voltage is the same as a preset voltage or not, if not, the cipherer does not work, and if yes, the cipherer sends a control signal to control an optical signal generation device; the light signal generation device emits a plurality of lights with different wavelengths, the lights are transmitted to the spectrum identification module of the identifier through the filter lens, the spectrum identification module identifies light waves to form a time sequence spectrum, and then the identified time sequence spectrum is compared with the time sequence spectrum stored in the identifier, so that the identity identification is successful. The light emitted by three or more LED lamps with different wavelengths after the LED lamps are arranged according to a circular rule can theoretically have countless combinations to form a time sequence spectrum with special light intensity, the recognizer filter lens is also a lens for filtering special wavelengths, and light intensity information with the spectrum cannot be copied by other equipment except for the LED lamp secret key in the method, so that the time sequence spectrum with special light intensity can be obtained. And the possibility of technical cracking is avoided.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to an identification method based on time series spectrum. Background technique [0002] Most of the existing identification systems use the settings of security control technologies such as passwords, mechanical locks, and radio frequency devices to realize restricted functions and achieve the purpose of identification and security control. Although they all have the advantage of stable performance, they are easily cracked, which is their Achilles' heel. Therefore, it is necessary to design a recognition method based on time-series spectra. Contents of the invention [0003] The purpose of the present invention is to provide an identification method based on time-series spectrum to solve the technical problems mentioned in the background art. While the cost of accurate identification is low, it overcomes the situation that it is easy to be cracked by technology. [0004...
