Computer generated data is not born with integrity. Nor is it born with authenticity. Business, legal and regulatory drivers increasingly require that an enterprise show information life cycle transparency. This is accomplished in large part by demonstrating authenticity and integrity of enterprise digital information. TimeCertain® technology was developed in response to the need for enterprise to create and maintain, over time, testable digital data content integrity and authenticity, with no need for access through the enterprise security perimeter. TimeCertain Chronologics® locally based (and always accessible) volume-scalable trusted time stamping service provides demonstrable digital data authenticity and integrity, and in turn provides enterprise with a key transparency element to information life cycle management.
