Related information of alcohol products can be determined in real time so as to guarantee health of users, and meanwhile, the fields of illegal wine distribution and the like are effectively attacked through regional consumption identifiers always contained in dynamic digital asset metadata: if a bottle is only authorized to be sold in a specific region, and a user scans the same bottle in an unauthorized region, a smuggling behavior is technically formed, so that the user experience is improved. Therefore, the problem can be solved in the same way. The system is easy to implement in an alcoholic beverage production enterprise, the production line efficiency is not reduced, and consumer behavior data which cannot be realized in the past can be obtained.
