Data hiding technique for omnidirectional JPEG images displayed on VR spaces

We propose a data hading technique for images in this paper. Our technique hides additional data of images into image data area for not being separated each other easily. The proposed technique uses omnidirectional JPEG images as cover data because of the huge amount of the embeddable area. Moreover, the embedded omnidirectional image can be viewed on VR space and the embedded data are extracted and playing in VR spaces using HMDs. We verified that our technique embedded the additional image into images efficiently in terms of PSNR, payload and overhead.

I. Introduction

Nowadays, to view virtual Reality (VR) content using head mounted displays (HMDs) is very popular[1] [2]. VR applications make us feel like we are in a real world without actually going to that specific place. In addition, omnidirectional cameras are popular, and people take omnidirectional images everywhere.
