Abstract

A device for use in a system for tracking a chain-of-manipulation (CoM) of audio-video (AV) content includes a hardware processor, and a system memory storing a CoM tagging software code and an AV processing application. The hardware processor executes the CoM tagging software code to detect manipulation of the AV content by the AV processing application that modifies at least one of video or audio of the AV content, and to generate, when the manipulation is detected, one or more CoM tag(s) including a device identification tag identifying the device used for modifying the AV content. The hardware processor also executes the CoM tagging software code to insert the CoM tag(s) in each modified segment of the AV content modified by the AV processing application, the inserted CoM tag(s) being human and machine imperceptible when the AV content is played back by a playback device on a display.

Background

BACKGROUND (1) Many audio-video (AV) editing applications are presently available for use that enable the modification of originally produced AV content. In some instances, use of these editing applications is for legitimate artistic reasons. In some other instances, use of such editing applications may be largely innocuous and innocent of any ill intent. However, in some other instances, use of such editing applications to manipulate AV content can be more sinister. For example, AV content can be manipulated through the addition of false or misleading content, or through the deletion of original content to intentionally alter the context or messaging of the AV content. (2) Due to the widespread popularity of AV content for the distribution of entertainment and news, effective management and control of legitimately created or edited content is important to the owners and distributors of that content. However, the unauthorized manipulation of AV content described above, whether performed innocently or maliciously, is typically difficult to detect. As a result, subtly altered or even substantially “fake” content may inadvertently be used in place of original AV content or authorized modifications to that original content in violation of contractual agreement or regulatory restrictions, thereby subjecting the content owners and/or distributors to potential legal jeopardy. SUMMARY (3) There are provided devices and methods for use in systems for performing automated chain-of-mani

Claims

1. A device for use in a system for tracking a chain-of-manipulation (CoM) of an audio-video (AV) content having a plurality of segments, the device comprising: a hardware processor; a system memory; and a CoM tagging software code and an AV processing application stored in the system memory; the hardware processor configured to execute the CoM tagging software code to: detect a modification of the AV content by the AV processing application, wherein the modification modifies at least one of a video content or an audio content of one or more segments of the AV content; generate, after detecting the modification of the AV content by the AV processing application, one or more CoM tags to track the modification, wherein the one or more CoM tags include a device identification tag identifying the device which performed the modification of the AV content; and insert the one or more CoM tags in the one or more modified segments of the AV content modified by the AV processing application, wherein at least one CoM tag is inserted in each of the one or more modified segments, wherein the inserted one or more CoM tags are human and machine imperceptible when the AV content is played back by a playback device on a display. || 9. A method for use by a device for tracking a chain-of-manipulation (CoM) of an audio-video (AV) content having a plurality of segments, the device including a hardware processor and a system memory storing a CoM tagging software code and an AV processing application, the method comprising: detecting, by the CoM tagging software code executed by the hardware processor, a modification of the AV content by the AV processing application, wherein the modification modifies at least one of a video content or an audio content of one or more segments of the AV content; generating, by the CoM tagging software code executed by the hardware processor after detecting the modification of the AV content by the AV processing application, one or more CoM tags to track the modification, wherein the one or more CoM tags include a device identification tag identifying the device which performed the modification of the AV content; and inserting, by the CoM tagging software code executed by the hardware processor, the one or more CoM tags in the one or more modified segments of the AV content modified by the AV processing application, wherein at least one CoM tag is inserted in each of the one or more modified segments, wherein the inserted one or more CoM tags are human and machine imperceptible when the AV content is played back by a playback device on a display.
