近年來受到數位化的影響,數位相機普遍被社會大眾所應
用,使數位相機結合資料隱藏技術是一像重要的議題。數位相機
從景物捕捉到製成圖檔的過程中需要經過多次運算。為降低成本
與減少體積,數位相機通常只使用單一感光元件(Charge-Coupled
Device,CCD)和彩色濾波器陣列(Color Filter Array,CFA)來擷取
影像資訊,再利用內插方法將影像還原成全彩影像,此過程稱為
解馬賽克(demosaicking),解馬賽克被廣泛運用在數位相機的設計
中。資訊隱藏技術的好處在於能夠用於智慧財產保護,防止
其遭到破壞、偷竊。本文所提出之方法,將秘密資訊藏入在
內插回來的影像中可以提升秘密資訊的安全度是一項不錯的
應用。
本文所提出基於貝爾圖形的可逆式資料隱藏方法,將秘密資
訊藏入在經由貝爾濾波器處理過後的數位影像上後再進行傳遞。
透過本文提出之方法,在位元藏量 (bit per pixel, bpp)等於0.8 時,
其平均的影像訊號雜訊比(Peak Signal to Noise Ratios, PSNR)等於
52.98dB,在高藏量下仍保有較高的影像品質。在擷取秘密資訊
後,可以完整地回復數位相機原本所要輸出的影像。本文所提出
的方法簡單,容易直接植入數位相機上使用。
Digital cameras are generally applied to the general public in recent years. The
scene capturing and file storing process of digital camera involves multiple image
processing . In order to reduce cost and volume, digital camera usually utilizes one
CCD (Charge-Coupled Device) sensor and color filter array (CFA) for capturing
images, it reconstructs a full-color image using a color interpolation method, this
process is called Demosaicking. Demosaicking has been integrated into the design
of a variety of digital cameras. The intellectual property protection is advantage for
data hiding technique. Digital camera combines with data hiding technique is an
important issue.
In this paper, we propose a reversible data hiding algorithm for CFA mosaic
images. The proposed algorithm utilizes CFA interpolation for embedding hidden
data. Secret information is hidden into the demosaicking image. Experimental
results on CFA mosaic images demonstrate that the proposed algorithm can achieve
high embedding capacity while maintaining good image quality. When the
embedding rate is 0.8 bpp, the peak signal-to-noise ratio (PSNR) is about 52.98dB.
When the embedding rate is 5.0 bpp, the peak signal-to-noise ratio (PSNR) is about
25.11dB. The results indicate that the proposed scheme can embed more data with
less distortion. The proposed data hiding algorithm is very simple. It is easy to
implement in hardware or software in the digital camera.
