Abstract:     A system and method for verifying user identity, in accordance with the present invention, includes a conversational system for receiving inputs from a user and transforming the inputs into formal commands. A behavior verifier is coupled to the conversational system for extracting features from the inputs. The features include behavior patterns of the user. The behavior verifier is adapted to compare the input behavior to a behavior model to determine if the user is authorized to interact with the system.

First Claim:
Show all 6 claims
What is claimed is:     1. A system for verifying user identity comprising:
  • a conversational system for receiving inputs from a user and transforming the inputs into formal commands;
  • a behavior verifier coupled to the conversational system for extracting features from the inputs, the features including behavior patterns of the user, the behavior verifier including a probability calculator, the probability calculator being adapted to calculate a first probability that the user is authorized to interact with the system based on the user's behavior;
  • an acoustic and biometric verifier for determining acoustic and biometric information from the user and determining a second probability that the user is authorized to interact with the system based on the user's acoustic or biometric information; and
  • the behavior verifier including a probability mixer adapted for integrating the first probability with the second probability to verify that the user is authorized to interact with the system.
