<p>A device (16), a method, and a system (10) for providing control of access (16) to data which is stored in an electronic data storage device (18). The device (16), method and system (10) enable various types of permissions to be set for determining access to the stored data, such that if an attempt is made to access particular data which does not have a suitable permission type, access is denied. Preferably, the present invention is implemented as an access control device (10), such as a chip, for example, which more preferably controls all access to the data storage device. This implementation is preferred, since such electronic devices are more difficult to 'hack' for access by an unauthorized user. The device (16), a method, and a system (10) have a number of different utilizations, such as controlling access to onboard credit card information; for identifying a user according to a PIN or other identification information; for controlling access to a secure location; for controlling file access to various types of files, such as MP3 music files and so forth.</p> |
