Amazon has been recently granted a patent that brings its facial recognition technology to its Ring doorbell business. According to the ACLU, the patent will allow homeowners to scan the faces of strangers that pass by their homes and cross-reference the image with a database of suspicious individuals that have been tagged by other people in the neighborhood. If a match is confirmed, then the images from the Ring doorbell and the database will be sent to law enforcement and the police could arrive in minutes. An image of the suspicious person is sent to the homeowner's phone. The system can use cameras from multiple sources such as various neighborhood houses to build a 360 degree composite image of the suspect. This patent application also suggests that Amazon has no plans to stop at identifying people based on their faces. The company anticipates targeting an arsenal of other biometrics, including fingerprints, skin-texture analysis, DNA, palm-vein analysis, hand geometry, iris recognition, odor/scent recognition, and even behavioral characteristics, like typing rhythm, gait, and voice recognition.
