Benefits of technology
[0020] The corrective action may include disabling at least one functional capability of the receiver. The corrective action may also includes launching a legal action against any alleged user of the receiver. Further, the corrective action may be executed in an automated manner. Still further, the corrective action may be executed at a time tending to minimize disruption of operation of the network.
Problems solved by technology
Furthermore, a conditional access system or and other systems with service or signal authorization records may not necessarily provide facilities for a large number of content providers to enter authorizations or to manage billing and other customer-oriented functions.
Likewise, conditional access systems known in the art may not provide interfaces or functions for the handling of large volumes of transactions except through a connection to a subscriber management system.
Where such facilities may be provided within a conditional access system, network operators may not be accustomed to using them, as they may not provide convenient or easily usable interfaces, and they may not include logging and other audit trail mechanisms.
Some conditional access systems known in the art have been compromised in a manner that allows for unauthorized usage of content signals.
Methods of compromising these systems include deliberate or accidental operational errors, exploitation of design or operational flaws in the systems, and “hacking” or reverse-engineering of the systems.
Detection of unauthorized access and usage may often be rendered difficult, as a compromised receiver may not have a method of communicating back with the conditional access system, or the return communication means may be disabled on the compromised receiver.
Correction of conditional access problems may also be a lengthy process, with compromised (also known as “pirated”) systems sometimes remaining in operation for several years, with a succession of counter-measures and counter-counter-measures being deployed respectively by the content delivery network operators and hackers.
Operational errors, software or hardware problems or other sources of errors may cause discrepancies to occur between subscriber management systems, conditional access systems and other systems such as video-on-demand servers.

Example
[0036] The description which follows and the embodiments described herein are provided by way of illustration of an example, or examples, of particular embodiments of the principles of the present invention. These examples are provided for the purposes of explanation, and not limitation, of those principles and of the invention. In the description, which follows, like parts are marked throughout the specification and the drawings with the same respective reference numerals.
[0037] According to one embodiment of the present invention, there is provided a method and system for detecting the possibility of unauthorized signal usage or service authorization configuration in a wireless or wired signal distribution environment. A method provided by the embodiment may be used to determine whether unauthorized usage of signals may be taking place, or whether or not a receiver configuration within authorization and related systems is consistent with properly authorized or unauthorized receivers

A method and system for auditing unauthorized usage in a subscriber content delivery network is described. The method and system includes identifying an indicator relating to accessibility for a receiver intended for receiving signals through the network; obtaining an indicator relating to authorization for a pre-determined service offering of the network; and determining whether the indicator of access ability is consistent with the indicator relating to authorization to thereby ascertain that the receiver is capable of engaging in unauthorized usage. The method and system may optionally include undertaking an action to change at least one of the indicator of access ability and the indicator relating to authorization.
