timestamp

(redirected from Digital timestamping)

timestamp

The time of day recorded in a transaction. The current time is maintained by the computer in minute fractions of a second and is used for a variety of synchronization purposes including determining transaction order in the event of a system failure.

Keeping Voice Over IP Synchronized
Instead of the time of day, a timestamp may be a time relative to a starting point. For example, voice packets in IP telephony (VoIP) are given a sequential timestamp by the RTP protocol so that they can be buffered at the receiving end and delivered uniformly to the listener. See NTP.

The existence of the '954 Patent had actually caused the Internet Engineering Task Force, an international standards setting body, to suspend implementation of an international standard for digital timestamping.
The lawsuit went to trial on October 25, 1999, with Entrust contending that "hash-and-sign" digital timestamping preexisted the '954 Patent.
On November 3, 1999, after six days of trial, including highly technical testimony centering on certain types of cryptography, the jury agreed with Entrust and decided that the "hash-and-sign" digital timestamping method of the '954 Patent was not new at the time of its purported invention and was always the obvious way to timestamp a computer file.
The jury invalidated Surety's patent on "hash-and-sign" digital timestamping and returned a verdict for Entrust.
