[0002] The identification carrier refers to a physical entity carrying an identification code. According to whether the identification carrier can actively communicate with an identification data reading and writing device, an identification analysis service node and an identification data application platform, the identification carrier can be divided into two categories: an active identification carrier and a passive identification carrier. In the industrial internet, the passive identification carrier generally only carries an industrial internet identification code, lacks remote network connection capability, needs to rely on an identification reader to initiate an identification analysis request to an identification analysis server, has weak security capability, lacks necessary security capabilities such as certificates, algorithms and keys. At present, common passive identification carriers include one-dimensional bar codes, two-dimensional bar codes, RFID and NFC. The passive identification carrier has the problems of easy information theft, the need for an identification reader to read information, weak security capability and the lack of certificates, and is only suitable for device component or industrial single product identification.
