  • Patent number: 11943363
    Abstract: Described herein are a system and techniques for enabling biometric authentication without exposing the authorizing entity to sensitive information. In some embodiments, the system receives a biometric template from a user device which is encrypted using a public key associated with the system. The encrypted biometric template is then provided to a second entity along with a biometric identifier. Upon receiving a request to complete a transaction that includes the biometric identifier and a second biometric template, the second entity may encrypt the second biometric template using the same public key associated with the system and perform a comparison between the two encrypted biometric templates. The resulting match result data file is already encrypted and can be provided to the system to determine an extent to which the two biometric templates match.

  • Patent number: 11481757
    Abstract: Methods for wireless payments using the Bluetooth low energy (BLE) protocol are provided. A first method includes establishing a wireless-short range communication link from a communication device to a peripheral device associated with an access device. The communication device receives item level data associated with an item being processed by the access device. The communication device displays the item level data associated with the item and transmits payment data to the access device. A second method includes establishing wireless-short range communication link to from a peripheral device associated with an access device to a communication device. The peripheral device transmits item level data associated with an item being processed by the access device, wherein the communication device displays the item level data associated with the item and receives payment data from the communication device.

  • Patent number: 10803504
    Abstract: A computerized method for integrating actionable items using a messaging artificial intelligence. A first actionable item is provided to a user for selection. In response to the selection, a processor activates a messaging artificial intelligence (“AI”) for instantiation in a messaging software. The messaging AI interacts with the user in the messaging software as a function of the message and the action and obtains parameters for the action. The messaging AI determines to terminate the interaction and, once terminated, the messaging AI generates a second actionable item for execution by a data payload execution platform. The data payload execution platform executes the second actionable item to complete processing of the action in the first actionable item.
