Abstract

According to the invention, an apparatus and methods for detecting modifications to information within a content receiver are described. In one embodiment, a method for detecting modification to a content receiver within a conditional access system is disclosed. In this process, a content provider generates a message. The message is sent to the content receiver by way of a network. The content receiver gets the message from the network. The content provider detects any unauthorized modification to the content receiver.
