Latest Patents
One of her latest patents is a method of authorizing a key or lock device. This method involves creating a first user device and a first system device used in the initial level of a lock system, such as at a manufacturer. A first encryption key is stored in both the first user device and the first system device. When the user device is to be shipped to a second level of the lock system, such as a locksmith, an authentication process is conducted using the first encryption key. If the authentication is successful, a software operation replaces the first encryption key with a second encryption key, which is then stored in the second system and user devices. This process prevents unauthorized use of keys and locks.
Another notable patent is a key and lock device that comprises a key with a first electronic circuit and a lock with a second electronic circuit. Both the key and the lock store secret information, some of which is unique to each device. They exchange a random number through connectors and perform calculations based on this random number and the secret information. An electrical blocking mechanism is activated to a non-blocking position if the calculations yield the correct result.
