Unique ‘Listening’ Technology Enables Joint Venture to Tackle Widespread Fraud Issues

That doesn't sound like my signature (Press Release)

This partnership was formed to commercialize a Rolls-Royce developed signature verification technology called SignHear in several markets including healthcare, retail banking and child care security.

SignHear dynamic signature verification by Alaris is a biometric technology that verifies identity by analyzing the unique sound patterns created by an individual’s written signature. These sounds are captured and analyzed by a patented algorithm that generates an acoustic signature template unique to each user. The technology was originally developed by Rolls-Royce to run quality tests on jet engine blades. By firing a sound impulse into a blade and analyzing the resulting wave patterns, engineers were able to determine if any structural faults or anomalies were present.
