Abstract
A content delivery apparatus, when a content delivery request is outputted from a user terminal device, encrypts the requested content with an encryption key, adds a view period to it to deliver it to a request source and delivers a viewing key in response to a view request from the user terminal device within the view period. A user relief management unit monitors failure information notifying, grasps a delivery disabled period from the failure information, specifies a delivery destination user for a content of which the view period is overlapped with the delivery disabled period and issues a relief right with a relief period specified thereto to the specified user. A contract period processing unit manages the relief right and permits viewing within the relief period set by the relief right when a view right based on the relief right is output from the user terminal device.
