The registration server is independent of digital product manufacturers and open to all digital product manufacturers. The manufacturer registers his digital product to the server and gets product registration file of the product from the server. The product manufacturer merges the product and the product registration file and encrypts them using manufacturer digital product license control program. If a public digital product is executed on user computer, said digital product is linked to digital product execution program which is subsystem of user digital product license control program. The program decrypts said digital product and reads the product ID from the product registration file and checks the license file received from a digital product registration server. If there is no license for the digital product, said program asks the user to buy a license of the product. |
