Abstract
Content screening operations are facilitated in devices that receive a content that is subject to screening obligations. When such a content is received at a device, a watermark extraction record is obtained and accessed to fulfill content screening obligations. Upon the receipt of such an extraction record, verification of the received extraction record is carried out based on a verification rate. If the verification is successful for an extraction record with permissive information, the verification rate is decreased, thereby reducing the processing load of the device. If the verification is unsuccessful, the verification rate is increased, which can adversely affect the processing load of the device.
