Abstract—Data hiding is a technique of transmitting additional information via host data such as digital images. It serves as a better way of securing message for the purpose of identification, annotation and copyright. Its main application is to increase or enrich the content. It aims to cover a significant amount of data in the host image with the minimum possible distortion. This paper deals with reversible data hiding technique with high insertion capacity. The scramble of data hiding is assured with a chaotic map. Indeed, the method manipulates in the Discrete Cosine Transform (DCT) and operates the specifications of the YCBCR color space. Our method provides high capacity insertion while maintaining the strength of the mark against attacks that can achieve the modified file. The proposed schema exploits the frequency domain benefits and the YCbCr color space; this allows robustness against compressed modalities and improved visual quality. Thanks to chaotic phenomenon data hiding is carried out safely.
