Cloud-Based Multimedia Content Protection System

 Abstract

We propose a new design for large-scale multimedia content protection systems. Our design leverages cloud infrastructures to provide cost efficiency, rapid deployment, scalability, and elasticity to accommodate varying workloads. The proposed system can be used to protect different multimedia content types, including 2D videos, 3D videos, images, audio clips, songs, and music clips. The system can be deployed on private and/or public clouds. Our system has two novel components: (i) method to create signatures of 3D videos, and (ii) distributed matching engine for multimedia objects. The signature method creates robust and representative signatures of 3D videos that capture the depth signals in these videos and it is computationally efficient to compute and compare as well as it requires small storage. The distributed matching engine achieves high scalability and it is designed to support different multimedia objects. We implemented the proposed system and deployed it on two clouds: Amazon cloud and our private cloud. Our experiments with more than 11,000 3D videos and 1 million images show the high accuracy and scalability of the proposed system. In addition, we compared our system to the protection system used by YouTube and our results show that the YouTube protection system fails to detect most copies of 3D videos, while our system detects more than 98% of them. This comparison shows the need for the proposed 3D signature method, since the state-of-the-art commercial system was not able to handle 3D videos.

Aim

The main aim of this paper is to provide cost efficiency, rapid deployment, scalability, and elasticity to accommodate varying workloads

Scope

The scope of this paper shows the need for the proposed 3D signature method, since the state-of-the-art commercial system was not able to handle 3D videos.

Existing System

The problem of protecting various types of multimedia content has attracted significant attention from academia and industry. One approach to this problem is using watermarking, in which some distinctive information is embedded in the content itself and a method is used to search for this information in order to verify the authenticity of the content. Watermarking requires inserting watermarks in the multimedia objects before releasing them as well as mechanisms/systems to find objects and verify the existence of correct watermarks in them. Thus, this approach may not be suitable for already-released content without watermarks in them. The watermarking approach is more suitable for the somewhat controlled environments, such as distribution of multimedia content on DVDs or using special sites and custom players. Watermarking may not be effective for the rapidly increasing online videos, especially those uploaded to sites such as YouTube and played back by any video player. Watermarking is not the focus of this paper.

Disadvantages

·      Illegally redistributing multimedia content over the Internet can result in significant loss of revenues for content

·      Finding illegally-made copies over the Internet is a complex and computationally expensive operation

Proposed System

The goal of the proposed system for multimedia content protection is to find illegally made copies of multimedia objects over the Internet. In general, systems for multimedia content protection are large-scale and complex with multiple involved parties. In this section, we start by identifying the design goals for such systems and our approaches to achieve them. Then, we present the high-level architecture and operation of our proposed system.
