Samsung patents system for sharing biometric data between devices

Patent drawing
Patent drawing from the official filing.

Samsung describes a system where a phone or tablet shares a digital fingerprint of your biometric data with a separate external device over a wireless connection. The external device adds specific attributes to this data to create a secure template, which the main device then verifies before allowing an app to run on the external hardware.

Why it mattersThis approach could allow users to securely access apps on external hardware, like smart displays or accessories, without needing to re-enter passwords or fingerprints directly on that secondary device.

In the filing’s own words

A system is provided. The system includes an electronic device having a biometric recognition module and an external device connected to the electronic device, wherein while the electronic device and the external device are connected through wireless communication, the electronic device provides the external device with a biometric data template obtained from the biometric recognition module, the external device stores a remote authentication template obtained by assigning a plurality of attributes to the biometric data template, the external device transmits the remote authentication template to the electronic device in response to an application execution request from a user, the electronic device checks a validity of the remote authentication template, based on a comparison between the remote authentication template and the biometric data template, and the external device requests biometric authentication from the electronic device, based on the validity checked from the electronic device, and execute the application, based on a result of biometric authentication of the electronic device.

What exactly they claim (claim 1)

1. A system comprising: an electronic device having a biometric recognition module and an external device connected to the electronic device, wherein, while the electronic device and the external device are connected through wireless communication: the electronic device provides the external device with a biometric data template obtained from the biometric recognition module, the external device stores a remote authentication template obtained by assigning a plurality of attributes to the biometric data template, the external device transmits the remote authentication template to the electronic device in response to an application execution request from a user, the electronic device checks a validity of the remote authentication template, based on a comparison between the remote authentication template and the biometric data template, and the external device requests biometric authentication from the electronic device, based on the validity checked from the electronic device, and executes the application, based on a result of biometric authentication of the electronic device.
