1. A system comprising:
- a first application and an associated first instance of a first service block access key;
a second application and an associated second instance of the first service block access key;
the first service block access key shared by the first application and the second application, the first service block access key used directly for authorized access to a first service block, the first service block access key being distinct from a credential received via input from a user;
a memory storing the first service block that is accessible using the first service block access key and inaccessible without the first service block access key, the memory communicatively coupled to receive the first instance of the first service block access key directly from the first application, and the second instance of the first service block access key directly from the second application; and
a personal digital key including the memory, the personal digital key accessing the first service block using the first instance of the first service block access key, and accessing the first service block using the second instance of the first service block access key.

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.

11. A method comprising:
-
receiving, at a personal digital key including a memory, a first instance of a first service block access key directly from a first application, the first instance of the first service block access key being associated with the first application, and the first service block access key being distinct from a credential received via input by a user; selecting a first service block in the memory, the first service block accessible using the first instance of the first service block access key, and inaccessible without the first service block access key, the first service block access key shared by the first application authorized to directly access the first service block and a second application authorized to directly access the first service block; accessing the first service block using the first instance of the first service block access key; receiving, at the personal digital key, a second instance of the first service block access key from the second application, the second instance of the first service block access key being associated with the second application, and the second application being distinct from the first application; and accessing the first service block using the second instance of the first service block access key. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
