Using Personal Attributes to Uniquely Identify Individuals

A system comprising:

• data processing hardware;
• and
• memory hardware in communication with the data processing hardware and storing instructions that, when executed on the data processing hardware, cause the data processing hardware to perform operations comprising:
• receiving image data characterizing a face of an individual, the image data captured by a camera of a wearable device worn by a user, the wearable device comprising a microphone and the camera;
• receiving a voice-based command captured by the microphone of the wearable device, the voice-based command comprising a natural language command spoken by the user that requests the wearable device to identify the individual;
• in response to receiving the voice-based command, performing person identification to identify the individual by:
• extracting, from the image data characterizing the face of the individual, an evaluation vector;
• determining the evaluation vector matches a reference vector for the individual;
• and
• based on determining the evaluation vector matches the reference vector for the individual, determining an identify of the individual;
• and
• providing, for output from the wearable device, an identification cue that conveys an identity of the induvial to the user.
