Description of n-dimensional voice security access technology - Receiver of NSF STTR Grant
R&D Project - Dynamic Pass Phrase Voice Security System
iBiometrics n-dimensional patent pending is a challenge response access technology, which prompts for n number of dynamically generated random one-time voice pass phrases. This approach suits security applications that need to protect against replay attacks; it does not require the storage of user passwords or other private identity related information. Users are given a limited time to respond to a challenge prompt. If the genuine speaker responds with the correct pass phrase, verification is successful. The system uses speaker verification and speech recognition simultaneously to verify the pass phrase and the speaker's identity.

Description of voice security remote access technology
iBiometrics holds a fundamental data communications network security patent, which uses speaker recognition to authenticate the user (US patent no 5,153,918 - Security system for data communications). The patented system provides a secure access solution for voice capable electronic devices such as smart phones or soft phones on a personal computer, that communicate over a data network such as the Internet or Cellular networks. The technology applies to rapidly expanding converged network environments such as Voice over Internet Protocol (VoIP), and facilitates the use of fast growing automated speech systems and voice-enabled computers and intelligent personal devices.
Secure access across networks is needed by users and organizations alike. Amongst other benefits, such a system aids in automation, helps to prevent fraud and protect a user’s privacy. To accomplish this goal, the system incorporates a number of security techniques using biometric speaker verification to authenticate the user and includes optional device identifiers. A secure solution, which verifies users prior to authorized access, is often necessary today driven by increased threats as well as legal and regulatory requirements.
Technical overview
The patented system provides voice enabled electronic devices secure remote access through a central controller. Remote devices are equipped with an appropriate remote modem to communicate with the central controller over a data network. Specific security techniques included in the patent are user authentication, optional device verification and encryption of authentication information and subsequent communication. Identification of the user is validated through a combination of biometric speaker verification, pin and optional card authentication. Device authentication is optionally performed via the verification of a combined unique device number with a security controller derived random number over the network.
The system uses a fundamental method to secure communications between a host processor and at least one remote device on a data network. This method comprises of generating a digital signal at the remote location corresponding to an orally generated speech pattern of a prospective user. The signal is then stored, compressed and encrypted for communication to the security controller. The controller receives and decrypts the signal to form a usable compressed signal and then, using a speaker verification engine, compares it to a stored signal to permit access to the host computer in response to a match.
Remote voice enabled devices include the capability to receive an analog signal associated with a users’ speech, digitalize and compress the signal so that it can be transmitted on the data network. Several optional voice features included in the patent include adaptation and compression optimization.
