Theoretical studies on Electronic Time Stamping and Audit Logs Protection have focused mainly on safety, particularly, ?the identification of falsified contents or sequences through encryption." However, these studies don't consider such details as time (being punctual to the second) or which electronic documents or data are older or newer when looking at several different sites. We solve the problem of time accuracy by using digital TV as a base for judging the order relation of time information between two or more sites. We designed a new Electronic Time-Stamping protocol for Digital TV and invented a new digital publication infrastructure. This protocol can also accommodate the demand for ultra high-speed electronic commerce transactions in the future. Therefore, it will possibly become one of the important E-Business models or enterprise e-Service architectures. In this paper, we will show these procedures and compare them to procedures shown in other papers.
