TH41196A - Equipment and methods for certification of transmission in an interactive TV system. - Google Patents

Abstract

A manageable interaction program is combined with audio / video data for transmission. Programs are divided into modules similar to computer files. And an introductory module will be made. To bind modules, a safety program for manageable applications is provided by attaching. The certifications that were recorded in the module referral. The inclusion of modules is verified by dividing the modules. And combining the split values in the introduction module. A split value of the referral module with another share is generated. Encrypt and stick with the introduction module. At the certified receiver will be decrypted and checked for Giver certification If the certification is secure, the program will run exclusively. If the receiver generates The program module's split value is the same as the corresponding split value in the introduction module.
