Abstract
Abstract A method and system for notarizing digital data, such as digital signature data, determines a subscriber compromised distribution latency period prior to authenticating the digital data. Upon receiving a notarization request, the system and method stores the digital data for notarization and holds the evidence or digital data for the latency period and as such waits to notarize the digital data in response to the subscriber compromise distribution latency period.
