On the Study of Certified Originality for Digital Alteration Problem: Technology Developments of the Time Authentication

In our modern clock-ruled culture, it is not too much to say that no society can exist unless based on “time”. Computers, which are the key device of an information society, are equipped with high precision clocks to synchronize their entire circuit function. In an electronic environment or digital society built on computers, recordkeeping relates inevitably to the time that is ticked away by the clocks embedded in the computers. Time is thus the infrastructure of this information society. The scope of discussion here focuses on some specific industries and applications for time-stamping technologies. We focused mainly on time-authentication (timestamp). This study will be further refined step by step as their validity is verified in actual use.
