In this contribution a novel reversible data hiding scheme for digital images is presented. The proposed technique allows the exact recovery of the original image upon extraction of the embedded information. Lossless recovery of the original is achieved by adopting the histogram shifting technique in a novel wavelet domain: the Integer Fibonacci-Haar Transform, which is based on a parameterized subband decomposition of the image. In particular, the parametrization depends on a selected Fibonacci sequence. The use of this transform increases the security of the proposed method. Experimental results show the effectiveness of the proposed scheme. © 2010 Copyright SPIE - The International Society for Optical Engineering.

Abstract
In this contribution a novel reversible data hiding scheme for digital images is presented. The proposed technique allows the exact recovery of the original image upon extraction of the embedded information. Lossless recovery of the original is achieved by adopting the histogram shifting technique in a novel wavelet domain: the Integer Fibonacci-Haar Transform, which is based on a parameterized subband decomposition of the image. In particular, the parametrization depends on a selected Fibonacci sequence. The use of this transform increases the security of the proposed method. Experimental results show the effectiveness of the proposed scheme. © 2010 Copyright SPIE - The International Society for Optical Engineering.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
