Digital asset uplink issuing method and system based on virtual printing drive

The invention provides a digital asset uplink issuing method and system based on virtual printing driving, and the method comprises the steps: sensing a printing output event of an information system, responding to the occurrence of the event, and triggering an uplink process; connecting a block chain digital space by using a virtual printing uplink drive, determining a main body identity of a received file, receiving identity authentication information, and determining an issuing object passing identity authentication; and issuing the file as an attachment of the digital asset to an account of the authenticated block chain main body according to a specified digital asset type. According to the method, seamless connection between the information system and the digital system can be realized, the digital transformation process is accelerated, the existing information system does not need to be transformed, the technical threshold, the implementation difficulty and the investment cost are reduced, the willingne
