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. |
