Business Editors/High-Tech Writers

OTTAWA--(BUSINESS WIRE)--Sept. 18, 2003

Validian Corporation (OTCBB:VLDI), an international provider of communication security technologies for networked environments, today announced the implementation of its Secure Instant Messenger system (SIM) in Cadillac Jack Inc.'s environment. Cadillac Jack is a premier manufacturer of video gaming equipment and software offering a full line of video-gaming devices that deliver the absolute best gaming experience through technical innovations.

"We are exchanging information and files with our clientele and business partners and this must be done in full security. We make it our business to understand our customers and their customers, challenging our engineers to continue to raise the bar in gaming systems design and development," said Mike Macke, Cadillac Jack President. "We have now three main branches in Georgia, Oklahoma and Texas as well as international locations. We also sell video gaming equipment and software and provide full operational support to a wide network of operators, casinos and game rooms in the U.S., Europe and Latin America. Security and speed of communication are paramount in our operations. We are very impressed at how easy Validian's SIM solution is to implement and operate; how SIM has enabled us to achieve both security and speed in our communications internally and with our suppliers and customers; and how SIM will help us contain costs as the number of our communications increases rapidly."

This commercial venture reinforces Validian's presence in the gaming sector, where the issues of design secrets, confidentiality of customer information and plans as well as customer service and communication effectiveness are critical.

"Cadillac Jack will take full advantage of SIM's capabilities, as it will facilitate communication between individuals and groups distributed over a wide area spanning many time zones. In particular, Cadillac Jack has commented on the usefulness of our store and forward capability," said Dr. Andre Maisonneuve, president and chief executive officer of Validian. "Sensitive customer files and information are circulated effectively and securely."

Validian's Secure Instant Messenger system (SIM) offers the highest level of security available for real-time communication and file exchange. SIM performs encryption of both messages and attachments within its own operation, so that data never travels in the clear at any point in time. It offers real-time features for collaboration between individuals and groups, including synchronous and asynchronous collaboration, enterprise-wide presence and secure file transfer features. Within a SIM exchange, all participants are authenticated and messages and files of any size and of any type, including video and audio files, can be transferred with full security. SIM is currently the only secure instant messenger specifically designed for, and the first to be carried on, a USB flash memory device.

SIM operates on Validian's Application Security Infrastructure (ASI) that provides SIM with all its security features. ASI addresses the requirement for secure transport of data, for authentication of participating entities and for establishment of a strong level of trust between these entities. ASI is particularly valuable in securing distributed applications operating over distributed networks. ASI automatically manages all critical security functions between any applications, including authentication, encryption, key generation, key distribution, addressing and data transport. SIM and ASI are software-only solutions, easy to install, manage and use. They allow organizations of all sizes to enjoy the benefits and flexibility of secure communications between applications, without the traditional costs and pain imposed by alternate solutions.
