Abstract

A media package storing program code, the media package comprising a medium storing a first part of the program code intended to be executed on a processor external to the media package, and a processing device storing a state and a second part of the program code, the first and the second parts of the program code being adapted to interact when executed so as to execute the program code. The processing device comprises a processor for verifying the state and for executing the second part of the program code if the verification of the state indicates that this is authorised; and a first interface for communication with the processor external to the media package. The processing device further comprises a second interface adapted to interact with a state change device in order to set the state from a first state not authorising execution of second part of the program code to a second state authorising execution of second part of the program code. The second interface is a Radio Frequency interface adapted to, when the media package is in the first state, interact with at least one anti-theft portal. Also provided is a system.

Claims

1. A media package storing program code, the media package comprising a medium storing a first part of the program code intended to be executed on a processor external to the media package, and a processing device storing a state and a second part of the program code, the first and the second parts of the program code being adapted to interact when executed so as to execute the program code, the processing device comprising:

a processor for verifying the state;

and for executing the second part of the program code if the verification of the state indicates that this is authorised;

a first interface means for communication with the processor external to the media package; and

a second interface adapted to interact with a state change device in order to set the state from a first state not authorising execution of second part of the program code to a second state authorising execution of second part of the program code;

wherein the second interface is a Radio Frequency interface adapted to, when the media package is in the first state, interact with at least one anti-theft portal.

3. The media package of claim 1, wherein the processing device further comprises means for authenticating the state change device.

5. The media package of claim 1, wherein the medium comprises the processing device.

6. A system comprising a media package of claim 1, a state change device, and a server adapted to authenticate the state change device, and wherein the state change device is adapted to change the state only upon successful authentication.

7. The system of claim 6, wherein the server is further adapted to, upon successful authentication, send the second part of the program code to the state change device for transfer to the processing device.

8. The system of claim 7, wherein the server is further adapted to verify if the processing device has been revoked before sending the second part of the program code.
