Methods and apparatus are provided for sequential authentication of a user that employ one or more error rates characterizing each security challenge. According to one aspect of the invention, a user is challenged with at least one knowledge challenge to obtain an intermediate authentication result; and the user challenges continue until a cumulative authentication result satisfies one or more criteria. The intermediate authentication result is based, for example, on one or more of false accept and false reject error probabilities for each knowledge challenge. A false accept error probability describes a probability of a different user answering the knowledge challenge correctly. A false reject error probability describes a probability of a genuine user not answering the knowledge challenge correctly. The false accept and false reject error probabilities can be adapted based on field data or known information about a given challenge.

A system and method for enabling communication concurrently over multiple access points and multiple physical media including but not limited to: cellular, network (e.g., Ethernet), broadband wireless, audio communication schemes.

System and method for supporting concurrent communication over multiple access points and physical media

An authentication framework is provided which enables dynamic user authentication that combines multiple authentication objects using a shared context and that permits customizable interaction design to suit varying user preferences and transaction/application requirements. For example, an automated technique for user authentication comprises the following steps/operations. First, user input is obtained. At least a portion of the user input is associated with two or more verification objects. Then, the user is verified based on the two or more verification objects in accordance with at least one verification policy operating on a context shared across the two or more verification objects. The user authentication technique of the invention may preferably be implemented in a flexible, distributed architecture comprising at least one client device coupled to at least one verification server. The client device and the verification server may operate together to perform the user authentication techniques of the invention.

A system and method for addressing mental health conditions includes a mobile processing device capable of executing a software application stored in memory. The software application is configured to employ peripheral devices associated with the mobile processing device to provide a user with a self-treating option for addressing mental conditions. When activated, the application provides one more of an interactive diagnosis routine configured to assist in discovering a mental state or condition of the user, and an interactive instructional routine configured to remedy a current mental state.

A method and apparatus for remote access to a target application is disclosed where a system administrator may establish telephonic contact with an interactive voice response system and obtain access to the target application by speech communication. The interactive response system may authenticate the system administrator by implementing various measures including biometric measures. Once access is granted, the interactive response system may broker a communication between the target application using text/data and the system administrator using natural language.

Method and apparatus for remote command, control and diagnostics of systems using conversational or audio interface

An authentication framework is provided which enables dynamic user authentication that combines multiple authentication objects using a shared context and that permits customizable interaction design to suit varying user preferences and transaction/application requirements. Such a framework provides a high degree of flexibility, accuracy, convenience and robustness. In one illustrative aspect of the invention, an automated technique for user authentication comprises the following steps/operations. First, user input is obtained. At least a portion of the user input is associated with two or more verification objects. Then, the user is verified based on the two or more verification objects in accordance with at least one verification policy operating on a context shared across the two or more verification objects. The user authentication technique of the invention may preferably be implemented in a flexible, distributed architecture comprising at least one client device coupled to at least one verification server. The client device and the verification server may operate together to perform the user authentication techniques of the invention.

An acoustic communication device includes a computer device having an acoustic transmitter and/or an acoustic receiver. A signal processing module processes sound signals such that the transmitter and/or receiver are employed to permit acoustic communication between computer devices using sound signals.

Method and apparatus for computer communication using audio signals

A computer program product includes machine readable instructions for providing enhanced video output by: receiving footage including likeness information in a plurality of modalities; demultiplexing the plurality of modalities to provide information for each modality; comparing information from at least two of the modalities for determining a correlation in the likeness information; using the correlation, obtaining semantic information for association with the likeness; and combining the semantic information with the likeness information for providing the enhanced video output. A system for implementing the computer program product includes resources for receiving the footage.

Multimodal identification and tracking of speakers in video

There is provided an apparatus for providing a Text Independent (TI) speaker recognition mode in a Text Dependent (TD) Hidden Markov Model (HMM) speaker recognition system and/or a Text Constrained (TC) HMM speaker recognition system. The apparatus includes a Gaussian Mixture Model (GMM) generator and a Gaussian weight normalizer. The GMM generator is for creating a GMM by pooling Gaussians from a plurality of HMM states. The Gaussian weight normalizer is for normalizing Gaussian weights with respect to the plurality of HMM states.

User interaction management techniques are disclosed. In a first aspect of the invention, an automated technique for managing interaction between a user and a system includes the following steps/operations. One or more behaviors associated with a user are observed as the user interacts with the system. A skill level of a user accessing the system is determined. Then, a user interaction profile is modified based on the determined skill level of the user. In a second aspect of the invention, an automated technique for generating a skill level classifier for use in classifying users interacting with a system includes the following steps/operations. Input from multiple users having various skill levels is obtained. Then, a classifier is trained using the obtained input from the multiple users such that the classifier automatically detects in which category of interaction skills a subsequent user belongs.

User interaction management using an ongoing estimate of user interaction skills

In large-scale deployments of speaker recognition systems the potential for legacy problems increases as the evolving technology may require configuration changes in the system thus invalidating already existing user voice accounts. Unless the entire database of original speech waveform were stored, users need to reenroll to keep their accounts functional, which, however, may be expensive and commercially not acceptable. Model migration is defined as a conversion of obsolete models to new-configuration models without additional data and waveform requirements. The present disclosure investigates ways to achieve such a migration with minimum loss of system accuracy.
