A vouching system and method provides an alternative means for authorizing access to protected content material. When a copy of content material ( 201 ) is deemed to be unauthorized by a rendering device ( 200 ), authorization can be obtained by contacting the source ( 100 ) of the copied material. If the copy ( 201 ) had been authorized, the source ( 100 ) re-certifies, or vouches for, the copy ( 201 ) to the rendering device ( 200 ). Upon receipt of this vouching, the rendering device ( 200 ) withdraws its rejection, and proceeds accordingly. Optionally, limits and security measures can be applied to this vouching process to minimize the potential for abuse.
