Google is seeking to drag YouTube into profit by convincing music and film footage rights owners to make advertising revenue from their content rather than remove it from the video-sharing site for breach of copyright.The company has been touting a fingerprinting system for rights holders that means YouTube can identify their material even when it has been altered and made part of user-generated content such as wedding videos or satirical clips.
