Embodiment Construction

[0031] figure 1 It is a diagram of the first embodiment of timestamp processing according to the present invention, which is described below in conjunction with Figs. 2-4 describing various features of the present invention figure 1 . Such as figure 1 As shown, the present time stamping process 10 begins at step 11 where a user prepares a request for a certificate R of a certain digital file F. An example alphanumeric representation of such a digital file F is as Figure 2A shown. The digital file F can be in digital form, or any representation of alphanumeric text (such as Figure 2A shown), or video, audio pictures or other forms of reliable data (not shown). Although this process can be used for files of any length, the Figure 2A An excerpt from that adequately represents a document that is required to be time-stamped.

[0032] According to the present invention, Figure 2B is the proof used to describe file F ( Figure 2A ) timestamp request R (by figure 1 An al...

Abstract

A process for time-stamping a digital document is provided. The process provides a certificate which not only allows for the authentication of a document at a later time but which includes a name or nickname which allows for the unique identification of the document at a later time. The name or nickname provided in accordance with the present invention is not only simple and concise but allows for the self-authentication of the document which it refers to. The name can be used when two independent parties desire to refer to the same unique document in a quick and simple way.
