Abstract
A method of implementing a network-enabled secure door lock, comprising obtaining measurements of an environment associated with a door from a variety of sensor types; generating, based at least in part on the measurements, a set of inputs to a machine-learning model; inputting the set of inputs into the machine learning model to determine a status of the door; generating a message that indicates the status of the door; and transmitting the message to a user device.
Claims21
A system, comprising:
- a first component of a lock mechanism, wherein the first component:
- comprises an interface to prevent relative motion with a second component of the lock mechanism;
- and
- uses a cryptographic key to cryptographically secure a message to the second component in order to verify relative motion with the second component is prevented in at least one direction.
A method, comprising:
- verifying an encrypted message generated by a first component of a lock mechanism with a cryptographic key using a microprocessor;
- wirelessly transmitting, as a result of the encrypted message being verified, an indication to a computing device that the first component is in an engaged position;
- encrypting a message with the cryptographic key to create a second encrypted message;
- and
- wirelessly transmitting the second encrypted message to a second component of the lock mechanism.
A system, comprising one or more processors to:
- use a machine learning model to generate a status of a lock mechanism based, at least in part, sensory data obtained from one or more components of the lock mechanism.
