Use of Steganographically-Encoded Data as Basis to Control Dynamic Content Modification as to at Least One Modifiable-Content Segment Identified Based on Fingerprint Analysis

Abstract:

The disclosure provides for use of steganographically-encoded data as a basis to control content modification. A server could determine through a fingerprint comparison that a portion of media content on a channel being rendered by a content presentation device matches at least one modifiable-content segment, such as at least one replaceable ad. The server could then use watermark data encoded in the media content of the channel as a basis to determine an actual identity of a modifiable-content segment present on the channel, so as to then control content modification.
