Intelitrak was founded in October 1995 by Joe Baranauskas, who became familiar with spook devices as a U.S. Marine Corps advanced security specialist in the 1980s. Like its founder, the company's speaker verification technology also has military roots. It is based on specialized software developed about 15 years ago to allow soldiers to authenticate each other's identities on the battlefield. The National Security Agency and the Department of Defense worked with ITT Industries of Ft Wayne, Indiana on the system. Intelitrak's voice-based system can be accessed by phone and thus remotely.
Users call into a protected system and the system verifies the user's voice.
The system then generates a time sensitive password, which lasts for five minutes. The whole process takes about 40 seconds, Intelitrak says. Most biometric systems work pretty much the same, including Citadel Gatekeeper and SecureTouch. Both systems capture a sample of the biometric characteristic. Unique features are extracted and converted into mathematical code.
