A machine-readable information carrier (2) contains content (video, audio, photographs, software, data; 2OA; 20B) 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, 3A) 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.
