Aladdin Knowledge Systems Introduces HASP DocSeal, Document Protection System

Easy-to-implement process protects intellectual property in seconds

CHICAGO, June 5, 2003 -- Aladdin Knowledge Systems Ltd. (NASDAQ: ALDN) today announced the availability of HASP DocSeal, a new digital document protection system based on Aladdin's proven HASP security key hardware.

HASP DocSeal is an advanced hardware-based system for protecting intellectual property and sensitive information. It is an ideal solution for companies that need to provide their employees and/or customers with access to confidential information, yet want to protect that information from being mass distributed. HASP DocSeal allows the encryption of HTML documents, ensuring the information is safe and secure, and restricted from unauthorized access and duplication.

In a matter of seconds, users can efficiently secure intellectual property and prevent the unauthorized copying, viewing, or manipulation of proprietary, personal, or confidential material.

"Information is most valuable to the enterprise when it is in the right hands at the right time," says Avi Barir, vice president software commerce. "With the HASP DocSeal system, valuable information is tightly controlled and protected so that only those who have the rights or clearances to view it will be permitted access. Secured in this manner, sensitive documents can be distributed more freely to authorized recipients without the risk."

The new HASP DocSeal system delivers ultimate document security within a simple, fast, and easy-to-implement framework incorporating unparalleled security of Aladdin's HASP USB or parallel port key, an automatic file encrypting tool, and an integrated viewer.

Proven in the real world by prominent software publishers looking to stop piracy, HASP encryption technology provides the strongest protection possible for HTML-based documents distributed via CD or DVD. Because the DocSeal system permits the assigning of unique IDs, users can also conveniently target specific documents to specific users.

HASP DocSeal incorporates Digital Rights Management technologies from C.D.I. Systems (1992) Ltd. This component--a document viewer--enables authorized users to conveniently read HASP DocSeal-protected HTML documents, while effectively preventing copying, printing or saving their content.
