METHOD FOR RESTRICTING ACCESS TO MEDIA DATA GENERATED BY A CAMERA
First Claim
1. A method for restricting access to media data generated by a camera, comprising:
- setting a non-public initial user key, KICU, in the camera,providing a user client with the initial user key, KICU,establishing an authenticated relation between the user client and the camera by sending an authentication message including information based on the initial user key, KICU, from the user client to the camera,checking if an operational user key, KOCU, is set in the camera, andperforming, in response to the act of checking if the operational user key, KOCU, is set in the camera, the acts a)-d) only if the operational user key, KOCU, is not set;
a) acquiring an operational user key, KOCU,b) setting the operational user key, KOCU, in the camera,c) setting the operational user key, KOCU, in the user client, andd) indicating in the camera that the operational user key, KOCU, is set,setting, in the camera, a media data encryption/decryption key associated with the operational user key, KOCU,encrypting media data registered by the camera using the media data encryption key, andsending the encrypted media data to a service provider management server.

Abstract
A method for restricting access to media data generated by a camera comprising: setting a non-public initial user key, KICU, in the camera, providing a user client with the initial user key, KICU, establishing an authenticated relation between the user client and the camera by sending an authentication message including information based on the initial user key, KICU, from the user client to the camera, checking if an operational user key (KOCU) is set in the camera, and performing, in response to the act of checking if the operational user key (KOCU) is set in the camera, the acts a)-d) only if the operational user key (KOCU) is not set: a) acquiring an operational user key (KOCU), b) setting the operational user key (KOCU) in the camera, c) sending the operational user key (KOCU) to the user client, and d) indicating in the camera that the operational user key (KOCU) is set.

11. A network camera arranged to encode media data registered by the camera, said network camera comprising:
-
a key generating means arranged to generate an initial user key, KICU, or an operational user key, KOCU, using a secure key generation process, an indication means arranged to indicate if the operational user key, KOCU, has been generated, a checking means arranged to check if the indication means has indicated that the operational user key, KOCU, has been generated, an encrypting means arranged to encrypt media data registered by the camera using a media data encryption key associated with the operational user key, KOCU, and a digital network module arranged to transmit the encrypted media data. - View Dependent Claims (12, 13, 14, 15)
