A system for preventing a standard garbage bag from forgery comprises a plurality of printing machines which prints unique data for preventing forgery for each standard garbage bag; a server for preventing forgery of a standard garbage bag which generates the data for preventing forgery, wherein the server sorts the printing machine requests data based on order data (filled with ′0′ for a vacant number) of n number of digits (n is multiple of 3) in providing the data to the printing machines, sorts a production date of the data for preventing forgery into a production date of eighteen-digits, divides the data of a production date and the order data by three-digits and adds the data by each digit, generates check-sum data by matching a number in the lowest digit of the result of summing each digit number with a predetermined alphabet, and generates the data for preventing forgery where the data of production date, the check-sum data, and the order data are sorted in a sequential order; and a web server which transfers a first point in time when a shipper ships standard garbage bag, a second point in time when a seller sells standard garbage bags, and a third point in time when a consumer buys a standard garbage bags to the server for preventing the forgery of standard garbage in accessing the data for preventing forgery stored in the server for preventing forgery of standard garbage bag and determines whether there is forgery based on the first point in time to the third point in time, and the data for preventing forgery. |
