Abstract
A playback device includes a port configured to receive content from an external memory device, a device memory residing in the device, and a controller programmed to execute instructions that cause the controller to read a read data pattern from the defined region in the external memory device and determine if the read data pattern correlates to an expected data pattern to a predetermined level, wherein the expected data pattern is derived at least in part from a defect map of the defined region.

-50. (canceled)
A system for validating media content, the system comprising a content memory device that is configured to:
- read a unique data pattern written by the content memory device of a validation entity, the unique data pattern being altered by known content memory device defects in the content memory device, the known content memory device defects being identified by a defect map that is stored by the validation entity;
- transmit the unique data pattern from the content memory device to a playback device such that the playback device is configured to validate the content memory device based on the unique data pattern and the defect map;
- and
- transmit content from the content memory device and to the playback device, responsive to a validation of the content memory device performed using the transmitted unique data pattern.
A method for securing media content, the method comprising:
- reading a unique data pattern written by a content memory device of a validation entity, the unique data pattern being altered by known content memory device defects in the content memory device, the known content memory device defects being identified by a defect map that is stored by the validation entity;
- transmitting the unique data pattern from the content memory device to a playback device such that the playback device is configured to validate the content memory device based on the unique data pattern and the defect map;
- and
- transmitting content from the content memory device and to the playback device, responsive to a validation of the content memory device performed using the transmitted unique data pattern.
A non-transitory computer readable medium having program instructions stored thereon, wherein when executed by a processor, cause the processor to perform operations comprising:
- reading a unique data pattern written by a content memory device of a validation entity, the unique data pattern being altered by known content memory device defects in the content memory device, the known content memory device defects being identified by a defect map that is stored by the validation entity;
- transmitting the unique data pattern from the content memory device to a playback device such that the playback device is configured to validate the content memory device based on the unique data pattern and the defect map;
- and
- transmitting content from the content memory device and to the playback device, responsive to a validation of the content memory device performed using the transmitted unique data pattern.
