Abstract: Aspects of the disclosure relate to a voice authentication platform. The voice authentication platform may monitor remote communications to identify a first voice sample. The voice authentication platform may train a voice authentication model to output similarity scores, based on the first voice sample. The voice authentication platform may identify a second voice sample. The voice authentication platform may generate a similarity score by inputting the second voice sample into the model. The voice authentication platform may compare the similarity score to a threshold value. If the similarity score meets or exceeds the threshold value, the voice authentication platform may update a user profile. If the similarity score is below the threshold value, the voice authentication platform may initiate a security action. The voice authentication platform may create an iterative feedback loop to update the voice authentication model.

Abstract: An information-security process for enhanced user authentication is disclosed. In addition to username, password, dual-factor and/or other security, an authenticator is worn or carried on the person of a user. The authenticator can be detected to be within local range of a workstation and/or geolocated. If the authenticator corresponds to the user and the user's security information, and if the authenticator is in the correct range or location, access to the workstation can be authorized. Otherwise, it is rejected. Access can also be terminated automatically if the authenticator leaves the security range around the workstation or if a different user's authenticator enters the security range. Positional or range information can be determined by NFC, Bluetooth, BLE, RFID, Wi-Fi, triangulation, time-of-flight protocols/components distributed throughout work area(s) and/or embedded in workstation(s). Cooperative components working therewith are in the authenticator.
