Geographically-Aware and Targeted Secure Information Dissemination (GATSID)


OBJECTIVE: Develop a product enabling on-the-move warfighters to securely send and receive information that can be targeted and tailored for sender-specified geographic regions to rapidly react to changing battlefield conditions and deliver battlefield alerts. DESCRIPTION: The goal of the research and development effort is to build and demonstrate a software product called Geographically-Aware and Targeted Secure Information Dissemination (GATSID). GATSID will enable on-the-move warfighters, equipped with state-of-the-art wireless information appliances (e.g., handheld, commercially-available or militarized, or wearable computers), to securely send and receive information that can be targeted and tailored for sender-specified geographic regions, sectors, or operating areas. GATSID will enable mobile warfighters to rapidly react to changing battlefield conditions by delivering location-specific time-critical battlefield alerts and advisories. It will implement the following capabilities: 1. A geographically targeted information multicast service that enables an application to securely send data directed at mobile appliances situated within a specified geographic area. The area may be specified graphically (e.g., on a mapping display) or by identification label or geographic coordinates. A minimum of one point with operating radius or two or more points to define outer bounds of the affected area. 2. Range-restricted information dissemination service that delivers data securely to eligible mobile appliances within a given range (say 2 kms) of the information disseminator, where the latter could be a mobile wireless appliance itself. 3."Banner in the Sky"service that allows information to be"posted"within a specified geographic region. The posted information is then delivered securely to any eligible fixed or mobile appliance entering the region. 4. Adaptation and customization of delivered information based on user"s profile, user"s device, and wireless link capacity. In the GATSID concept, the mobile warfighters are equipped with wireless information appliances such as smart phones that support two capabilities: 1) a position location mechanism (e.g., a Global Positioning Satellite [GPS]); and 2) an (Internet Protocol) IP-based wireless interface for connectivity to the military Internet. All communication to and from the mobile appliances is thus accomplished over IP. A non-GPS-equipped device may be referenced for another known GPS-equipped device(s). GATSID will address a major aspect of the challenge of delivering"On-demand Information:"What you need . When you need it". It will enable future situational awareness systems where intelligence and tactical sensor data must be exploited to provide customized, location-specific information to the force. The following paragraphs present example scenarios to illustrate the application of GATSID: Example 1: An unmanned aerial vehicle (UAV) operator performing a reconnaissance mission notices what appears to be a suspicious enemy activity in an area where Special Operations Forces (SOF) operations are ongoing. The pilot can use GATSID to send a targeted warning or alert message to all SOF warfighters in the vicinity of the threat. These warfighters will immediately receive this alert on their mobile appliances and can take necessary actions to counter the threat. Example 2: A first responder to an emergency uses his or her handheld device to broadcast a call for help to medical response teams within a 5 mile radius around the site. All medical response teams receiving the message can respond back with the ones closest to the site directed to proceed to the emergency scene. PHASE I: Define, determine feasibility and demonstrate a means to collect and identify potential receiving nodes by class, location, or other means. Provide approach to capture the addresses (all modes) of identified receivers to provide multiple redundant alerts to the selected recipients. Provide demonstration using an accepted geospatial display from Sponsor POC (SPOC) recommended system(s). PHASE II: Construct and demonstrate the operation of a prototype system utilizing one or more handheld devices currently approved for use by USAF or SOF warfighters. Demonstrate capabilities to alert nodes to action for response as well as action to head to safety. Working with the sponsor, utilize these capabilities in one or more approved experiments or exercises. PHASE III: Provide usability assessment of Phase II system for final user interfaces that will engage with existing receiver devices (minimum of 4--one sent from air operations center, one sent to/from SOF/embedded Joint Terminal Attack Controller or similar, and other vignette(s) determined in Phase II.
