NEW YORK--(BUSINESS WIRE)--June 27, 2001

AuthentiDate, Inc, a leading provider of Trusted Content Authentication services and a subsidiary of AuthentiDate Holding Corporation (Nasdaq: ADAT), today announced that it has joined the RSA Secured(TM) Partner Program and received RSA Secured RSA Keon Ready Certification to support interoperability between AuthentiDate and the RSA Keon(R) public key infrastructure (PKI) software.

"We chose to team with RSA Security because it is a leader in e-security solutions and PKI technology. We were able to easily integrate the RSA Keon PKI software into our existing infrastructure allowing us to deploy digital certificates quickly and easily," stated Alex Cooper, vice president of business development at AuthentiDate, Inc. "Now that our service is commercially available we will initiate a marketing and sales campaign targeted at existing customers of RSA's security solutions."

"Proving that a document existed or a transaction occurred at a specific point in time and is irrefutable and authentic is a critical component of implementing a legally binding digital signature system," said David Kanto, director of partner development at RSA Security. "We are excited to welcome the AuthentiDate solution because it will provide RSA Keon customers additional value added services to leverage their investment in PKI infrastructure."

When combined with RSA Security's digital signature technology, AuthentiDate provides the strongest form of non-repudiation for securing electronic documents or transactions on any digital network. By offering the most accurate and auditable time stamping service available, AuthentiDate increases the integrity of digital signature solutions. A digital certificate from an accredited Certificate Authority proves who sent or authorized a transaction or document. AuthentiDate verifies content by proving when the electronic file was signed and that its content has not been altered. Furthermore, AuthentiDate hosts a repository of electronic records with digital timestamps that can be used for non-repudiation without relying on the original digital certificate.

AuthentiDate's patent-pending technology addresses the need for the verification of digital information in all business processes.
