Information recognition system based on liquid metal

Abstract

The invention provides an information recognition system based on liquid metal and relates to the technical fields of Internet of Things and information security. The information recognition system comprises an intelligent tag and a recognizer, wherein the intelligent tag comprises a sensor and a flexible circuit; the sensor is used for recording environment information of the environment of an article, and the flexible circuit is used for establishing connection with the recognizer and sending the environment information to the recognizer; the flexible circuit comprises a line made of the liquid metal and a micro-channel with a vacuum cavity; at least one end of the micro-channel is connected with the line made of the liquid metal, and the liquid metal can enter the micro-channel in a phase change to make the flexible circuit disconnected or short-circuited; and the recognizer is used for establishing connection with the flexible circuit, receiving the environment information and analyzing the environment information. Though the technical scheme, the information in the information recognition system based on the liquid metal can be securer.

Description

technical field [0001] The invention relates to the technical field of Internet of Things and information security, in particular to an information identification system based on liquid metal. Background technique [0002] Radio Frequency Identification (Radio Frequency Identification, referred to as RFID) is a communication technology that can identify specific targets and read and write related data through wireless telecommunication signals without establishing mechanical or optical contact between the identification system and specific targets. [0003] However, the information security of the information identification system using RFID in the prior art is usually to continuously improve the encryption algorithm under the communication protocol to obtain a higher security level, but the encryption method based on the algorithm is a solution at the software level, and the encryption program All have a certain logical form, and can still be cracked through a series of rev...
