The device or another device coupled thereto may then verify the accuracy of the responses from the user during the conversation, as well as compare an audio signature associated with the user's responses to a pre-stored audio signature associated with the user. By utilizing multiple checks, the described techniques are able to accurately and safely authenticate the user based solely on an audible conversation between the user and the voice-input device.

Abstract: Systems and methods generate a risk score for an account event. The systems and methods automatically generate a causal model corresponding to a user, wherein the model estimates components of the causal model using event parameters of a previous event undertaken by the user in an account of the user.

Abstract: In response to a conversion action associated with an online advertisement (“ad”), an advertiser associated with the ad generates a unique identifier (e.g., a pseudo random number), which is transmitted to a payment system through a user device. In some implementations, the unique identifier can be generated by a payment system in response to a request from an advertiser. The advertiser stores the unique identifier in a secure location that is accessible by the payment system. The payment system compares the received unique identifier with the stored unique identifier. If the received unique identifier matches the stored unique identifier, and if the received unique identifier was not previously generated by the advertiser, then the payment system deems the conversion action to be valid.

Abstract: Systems and methods for analyzing digital recordings of the human voice in order to find characteristics unique to an individual. A biometrics engine may use an analytics service in a contact center to supply audio streams based on configured rules and providers for biometric detection. The analytics service may provide call audio data and attributes to connected engines based on a provider-set of selection rules. The connected providers send call audio data and attributes through the analytics service. The engines are notified when a new call is available for processing and can then retrieve chunks of audio data and call attributes by polling an analytics service interface. A mathematical model of the human vocal tract in the call audio data is created and/or matched against existing models. The result is analogous to a fingerprint, i.e., a pattern unique to an individual to within some level of probability.
