METHOD FOR THE JOINT-CREATORSHIP VERIFICATION USING MULTIPLE DIGITAL WATERMARKING FRAMEWORK

摘要

virtual reality in a virtual environment data (virtual reality data, "VR data"), often by many authors Co is manufactured. This method should be taken to protect producers of co-ownership and participation of each title. In the present invention, multiple watermarking framework: To solve the problem by using a co-ownership (MDWF multiple digital watermarking Framework). Suggested wokeueun multiple watermarked frames, to demonstrate the co-ownership of the VR data produced through a collaborative, multi-watermarking technique utilizes a 3D secret key and the shared secret protocol. After the agreed key for secret key consisting of all, multiple watermarking framework is to insert the addition of 3D secret watermark for joint ownership. Thus, multiple watermarking framework can successfully resolve ownership disputes between the joint members. In other words, each of the participating producers, by multiple watermarking framework, can prove their partial ownership or co-ownership. Furthermore, multiple watermarking framework, a shared secret key (shared secret key: SSK), since the production by the respective user, can solve the collusion problem.
