Abstract
A personal digital key (e.g., which can be carried by a human) contains a memory having different service blocks. Each service block is accessible by a corresponding service block access key. As the personal digital key (PDK) moves around, it is detected by sensors. The sensors report position data, thus enabling location tracking of the PDK. The sensors also provide a data path to various applications. An application that has access to a service block access key can therefore access the corresponding service block on the PDK. The sensors themselves may also contain service block access keys.
Claims1
A method for supporting applications for a personal digital key (PDK) located in a sensor network having a plurality of sensors at known locations and a sensor management module (SMM) communicatively coupled to the plurality of sensors, the method comprising:
- establishing a wireless communication channel between a sensor and a PDK in the sensor's microcell;
- the sensor gathering position data about the PDK via the wireless communication channel;
- the SMM receiving the position data gathered by the sensors about a PDK, generating location tracking data for the PDK based on the position data and making the location tracking data available to applications;
- and
- providing a data path between a service block on the PDK and an application that has access to the corresponding service block access key, the data path including the SMM and the sensor.
