<p>A tracing and recalling system for managing commodity circulation based on internet includes the following steps: 1. a computer system obtaining a first group and a second group of data to be processed which are 13 decimal digits respectively; 2. deciding whether the first group of data and the second group of data meet a determined principle; 3. generating a third group of data by applying the encryption processing of commercial keyword algorithm to above two groups of data which meet the determined principle; 4. corresponding the first, the second and the third groups of data to a commodity; 5. separating the first, the second and the third groups of data into three rows, and printing them onto the corresponding commodity; 6. giving the commodity a corresponding tracing code with 6 digits; 7. displaying the tracing code on the website page; 8. displaying the information such as the first and the second groups of data etc. on a website page, and applying the inverse operation of encryption to the third group of data which is input through an input window, and then performing a checking computation, the system displaying a certification code of '0' or '1' to prompt the true or false information.</p> |
