Abstract: This study proposes the rotation, scaling and shift invariant reversible data hiding technique using scale invariant feature transform with embedding in wavelet domain. Also, the content is made secure by encryption using rotation invariant hash key. Rotation, scaling and shift invariant reversible data hiding is implemented using SIFT and embedding is done in wavelet domain and the results are analyzed. The experimental results show that, this scheme provides high embedding capacity with low distortion. Also, it is robust against rotation. The computational complexity of the proposed technique is low and the execution time is short compared to the existing methods like expansion embedding based reversible data hiding, histogram shifting based reversible data hiding and prediction based reversible data hiding.
