This article details the conception, design, development and analysis of invisible, blind and robust color image\r\nwatermarking algorithms based on the wavelet transform. Using error correcting codes, the watermarking algorithms\r\nare designed to be robust against intentional or unintentional attacks such as JPEG compression, additive white\r\nGaussian noise, low pass filter and color attacks (hue, saturation and brightness modifications). Considering the\r\nwatermarking channel characterized by these attacks, repetition, Hamming, Bose Chaudhuri Hocquenghem and\r\nReed-Solomon codes are used in order to improve the robustness using different modes and appropriate decoding\r\nalgorithms. The article compares the efficiency of different type of codes against different type of attacks. To the best\r\nof our knowledge this is the first time that the effect of error-correcting codes against different attacks are detailed in a\r\nwatermarking context in such a precise way: describing and comparing the effect of different classes of codes against\r\ndifferent type of attacks. This article clearly shows that list decoding of Reed-Solomon codes using the algorithm of\r\nSudan exhibits good performance against hue and saturation attacks. The use of error correcting codes in a\r\nconcatenation mode allows the non-binary block codes to show good performance against JPEG compression,\r\nnoise and brightness attacks.
