The present invention proposes a method for protecting and monitoring removable entities in an embedded system. In accordance with the present invention, prior to insertion of a removable entity in the embedded system, a user registers details of the removable entity in the device host. The details may be entered after entering a password or a PIN. A registration identification is calculated based on an algorithm in the device host and is then stored in the host. After the removable entity is inserted, it is registered in an unalterable area (e.g. flash memory) of the device host. Information such as the category of the removable entity, a device number, etc. may be exchanged between the device host and the removable entity. The device host then computes a registration identification based on a Removable Entity Registration Algorithm. The identifications are then compared, and the device host displays the details of the removable entity to the user.
