Asier will provide a collaboration tool with 2-way text messaging, file and image transfer, and limited voice capability over a secure, low-bandwidth connection. The Navy will benefit from wireless communication tools that act like a hybrid between e-mail and real time chat, storing messages, still images and video clips with an easy-to-use retrieval method. A new collaboration suite can be developed and fielded to operate on existing networks (with very limited bandwidth and intermittent connections) while simultaneously supporting multiple security levels. Asier's feasibility study proposes to provide in-line compression of text to accommodate low-bandwidth factor, provide embedded Asier multilevel encryption software to protect information transmitted across different levels of security classification, and provide encryption key management system to accommodate multiple security domains. The feasibility study will evaluate product designs that will accommodate limited audio transmittals with the ability to send still images or video clips and include a journalizing file system that will store and send messages collected during times of interruption. Instant text messages can be time-coded so that all missed messages would be re-sent when the user reconnected. User interface designs will be simple to use and ranked against Navy objectives. The use of Instant Messaging (IM) is growing exponentially in many segments of our society. Teenagers use it to chat. Many corporations use it for internal, instant communications. Cell phones with IM capabilities are the latest rage. With the appearance lately of digital cameras on cell phones, still photos can also be instantly sent. Instant video conferencing on cell phones and PDAs will no doubt be a reality in the near future. While these technologies can be easily implemented to satisfy the teen-age user market (which in itself is a large market), serious issues such as band-width constraints and security must be addressed to satisfy commercial, government, or military users. The successful implementation of this technology will resolve those issues. Secure instant messaging with low-data-rate audio, as described in this proposal, is needed today by the Navy, the other branches of the military, and the US Government not far behind. While no market data is readily available, this technology will find many uses in the public safety, law enforcement, homeland defense and medical environments. Not surprisingly, all of these market opportunities are closely related and have needs very similar to the Navy's that cannot be addressed adequately with products currently available. Police officers, firemen and customs agents all have to work in environments where wide-band wireless connectivity is typically unavailable and the connectivity that is there (CDMA, TDMA cell phone) is prone to interruptions as these personnel move into and out of structures that block transmissions. The command and control issues in the public safety sector closely parallel those of the military establishment. These public safety applications need security that is superior to the currently available standards (WEP) but perhaps not as much as the Navy. Anticipating this need, Asier has developed a lower-security version of the multilevel encryption algorithm that could be used for commercial sales to non-DOD clients. Other commercial areas where this technology might be applicable are in medical and financial records. Under the new Health Insurance Portability and Accountability Act (HIPAA), the secure handling of sensitive personal information, whether medical or financial, will be required. Doctors are more and more beginning to use wireless devices to carry with them on their rounds, or to have ready access to a patient's records. Downloading patient information wirelessly will need to be encrypted. This will be especially important as telemedicine inevitably grows in response to market demands to control the rising cost of healthcare. To that end, Asier has on-going dialogue with several healthcare systems and system integrators regarding the use of Asier encryption to help protect their valuable data. Without further modification, this technology has potentially significant applications in public safety. Portable command-and-control stations, with wireless connectivity to first-responders in the event of an emergency, will require secure and instant communications. Many of the senior research staff and administration at UTD have strong ties to many of the world leaders in communications and information technology. Dr. Feng the head of the Graduate Research Program (and organizer of this effort) was formerly a VP with SAIC. UTD has the strong desire and connections to spin off and commercialize technologies developed with their assistance. Asier, with the assistance of the UTD commercialization expertise and resources, will develop comprehensive plans to address each of these potentially huge markets
