A machine-readable information carrier ( 2 ) contains content (video, audio, photographs, software, data; 20 A; 20 B) with restricted access, wherein at least one portion ( 23 ) of the content is a restricted portion. The information carrier ( 2 ) further contains data ( 21 ) associated with the said content, the data ( 21 ) representing a machine-executable access application which contains machine-executable instructions for a reader device ( 3, 3 A) for controlling the reader device's access to the content of said carrier. The access application ( 21 ) is designed, when the reader device attempts an access to the restricted portion ( 23 ) of the content, to check authorization of the reader device, and to deny access to information in the said restricted portion ( 23 ) of the content if it finds that the reader device is unauthorized or to allow access to information in the said restricted portion ( 23 ) of the content if it finds that the reader device is authorized.
