The invention discloses a random encrypted physical information blockchain anti-counterfeiting system. The system comprises a fixed terminal, a 4G network and a mobile terminal, the fixed terminal comprises a central processor, an input end of the central processor is connected with an output end point of a data processing unit, an input end of the data processing unit is connected to an output end point of a data acquisition unit, and the data acquisition unit includes a fingerprint acquisition module, a face acquisition module and an iris acquisition module. According to the random encryptedphysical information blockchain anti-counterfeiting system, through the arrangement of the fingerprint acquisition module, the face acquisition module and the iris acquisition module, before an electric vehicle is used by a user, identity information of the user is acquired by the data acquisition unit at first, a data comparison unit is adopted for comparison to determine whether or not the useris an owner, if it is determined that the electric vehicle belongs to the owner, a red indicator light and a green indicator light are sequentially illuminated, if the user is not the owner, a buzzersounds, the electric vehicle is prevented from being stolen accordingly, and the economic loss caused to people is avoided.
