Abstract: A system assigns a unique prefix to a data table. The system generates a set of document identifications (IDs) for a set of data records included in the data table. The system generates a data key that corresponds to a combination of two or more columns of the data table. The system identifies one or more data records that share a key value with each other, where the key value is associated with the data key. The system determines that the one or more data records belong to a user based at least on identifying that the one or more data records share the key value with each other. The system assigns an entity ID to the identified one or more data records in response to determining that the one or more data records belong to the user.

Abstract: Disclosed are systems and methods including software processes executed by a server that detect audio-based synthetic speech (“deepfakes”) in a call conversation. Embodiments include systems and methods for detecting fraudulent presentation attacks using multiple functional engines that implement various fraud-detection techniques, to produce calibrated scores and/or fused scores. A computer may, for example, evaluate the audio quality of speech signals within audio signals, where speech signals contain the speech portions having speaker utterances.

Abstract: Embodiments disclosed herein include software processes and of machine-learning architectures for detecting and mitigating against synthetic speech instances. A computer analyzes audio speech data and metadata received with contact events associated with source identifiers. The computer executes machine-learning architecture(s) that determine whether the contact events likely include human-generated speech or machine-generated synthetic speech. The computer may determine the likelihood that contact events represent a DoS attack launched by a source device, by analyzing behavior features in metadata associated with the source identifier. The computer determines whether the contact events originated from the source user device having the source identifier launched a DoS attack and, if so, may update a blocklist.

Abstract: A data set may be replicated to another storage location according to a schema that projects a subset of the data set according to a replication technique. An additional replication technique, different from the first replication technique, that also projects a subset of the data set to a third storage location is performed. The correctness of the additional replication technique may be verified with regard to the data set to generate a performance report for the additional replication technique.

Abstract: Embodiments described herein provide for automatically authenticating operation requests and end-users who submit operation requests during contact events. A server obtains an operation request for an operation originated at an end-user device. The server generates a voice-based one-time password (OTP) using contextual information associated with the requested operation. The server generates and transmits an OTP prompt having text representing the OTP for display at a user interface of the user device. The server receives a response including an audio signal that contains the recording of the user speaking the OTP text aloud. The server uses the audio signal to authenticate the user and the operation request based on the speaker's voice, the accuracy of the user speaking the OTP, and liveness or fraud detection features extracted from the audio signal or metadata from the user device.

Abstract: Various techniques described herein relate to building and using representative data systems to store and manage representative profile data within contact centers. A representative data system integrates with external communication services and other internal/external systems to provide a uniform data store and interface to create and manage representative profiles. The representative data system retrieves and analyzes representative profile data during runtime contact center operations such as contact queuing, contact management, and/or workforce management. The representative data system may be implemented using relational or graph-based data structures to support advanced predictive modeling and impact analysis of scenarios such as service outages, dynamic workload shifting, infrastructure changes, and workforce changes.
