The system provides secure controlled access to multiple Bluetooth devices issued to users. For example an officer may be issued a weapon. To enable monitoring of weapon status, a Bluetooth sensor may be fitted to a holster and the Officer issued with a Bluetooth enabled mobile phone. In order to establish a secure Bluetooth connection between the devices, sensor contains a restored link key and the mobile phone stores a partial link key. The supervisor enters their username and password, and a secret key into the phone which is then used with the partial link key to generate a copy of the link key stored in the first device, so that a secure connection can be established with the first device. The officer enters their username and password into the sensor, and once the secure connection is established it is sent over the secure connection to the mobile phone which then sends both user names and passwords to a verification authority. If the officer is verified and authorized to issue the devices, an authorization message is returned and use of the devices allowed. If the authorization fails, a failure message is returned and the devices are not issued and features may be blocked. The verification authority may be internal or external to the phone. If the authority is external, then the supervisor's user name and password could be omitted.

Bluetooth pairing system, method, and apparatus

A system for securely controlling access between two wireless (i.e. Bluetooth-enabled) apparatuses, also comprising a supervisor apparatus. The first apparatus is paired to the second by establishing a secure wireless (i.e. Bluetooth) link. The first apparatus includes a stored partial link key and a link key generator: The first apparatus receives a first secret key from the apparatus user, and may also receive a second secret key from the supervisor apparatus. The link key generator generates either a first link key based upon a stored first partial link key, the first secret key and the second secret key or a second link key based upon the stored first partial link key and the first secret key. An access control module in the second apparatus determines the level of access that the first apparatus is granted based upon the link key used to establish the secure connection&#x2014;full/restricted access.
