Latest Patents

Sharma's latest patents include a "System and method for detection of fraud in a wireless telephone system." This innovative system utilizes a signature analyzer to assess the transmission characteristics of unauthenticated transmitters. If the system authenticates the transmitter based on stored records, it establishes a customer call profile that considers the geographical location of the wireless telephone and the time period of the communication. The system then analyzes subsequent calls against this profile to determine their validity. It is adaptive, periodically deleting old call data records to make way for newer ones.

Another significant patent is the "System and method for detection of redial fraud in a cellular telephone." This system analyzes calls identified as fraudulent through signature analysis and stores relevant parameter data associated with the fraudulent cell phone. During subsequent calls, the system compares this stored data to determine if the call is from the fraudulent device. By analyzing parameters such as the time of day, origin, transmitted identification numbers, and destination numbers, the system can efficiently identify fraudulent calls without extensive signature analysis.
