Internet, wireless, and video editing applications are rapidly adopting object-based MPEG4 standards. Allows for scaling, rotation, and translation to meet editing requirements while reducing the amount of data transmitted. In addition, it has the ability to transmit only objects (without the background) to meet dynamic network bandwidth requirements.

However, the object-based MPEG4 standard is difficult to secure from malicious attackers because they can easily access and modify the video object (VO) and copy it from one video to another. The safe transmission of videos is ensured by DRM protected content, but once the video reaches the user device, forensic watermarking schemes are needed to provide security. Owners and distributors of digital content are now using object-based watermarking instead of the traditional frame-based approach. An object is the unit of acquisition, editing, indexing, retrieval, coding, and distribution in such a case. The object functionalities, such as cutting and pasting, are very simple in comparison to the more advanced management and protection features of MPEG4. As a result, in the MPEG4 setting, object-based watermarking schemes are required.

Using a cloud-based watermark extraction service that works well even with low-quality and recompressed videos, it is possible to verify the owner of the content and track down the source of the piracy. Client-side watermarking, A/B or manifest-level watermarking, and bitstream-based watermarking are three broad categories of watermarking solutions.

An effective video watermarking service must be able to deter piracy, identify the piracy outlets, and take the necessary steps to prevent leakage of the video content. In order to detect piracy, keep an eye out for suspicious activity and compare the digital fingerprints of suspicious files to the production fingerprint. The watermarking software is then able to identify the watermark and extract the information contained therein. Resize and collusion attempts, for example, shouldn’t affect the robustness of the watermark. It should also remain legible even after the content has been altered. It’s also possible to take legal action after discovering the source of a stream that is being illegally downloaded.

Video authentication systems that use frames instead of objects as the basis for their authentication have their own unique set of requirements, while object-based video watermarking has its own set. If you’re using an object-based watermarking system, each piece of the video should be individually processed, signed, and authenticated before it can be used. First the video file is divided into foreground and background segments, each of which is then compressed to be sent over the internet. This information is used to create a watermark that is unique to each piece of content. The watermark can be embedded into the foreground objects to create a secure connection between them and the backdrop. The extracted watermark from the object and the extracted feature from the received object and background can be used to verify the video’s authenticity.

During malicious attacks, the VO and background information can be easily altered or replaced by another object (intentional distortions). The decompressed objects can be resized, rotated, or translated by the end user (incidental distortions). The most effective object-based watermarking solution, then, should be resistant to accidental distortions while also being able to detect distortions that are intended to meet specific video needs.
