| The following paper presents the results of tests conducted by the author in the field of verification of influence of JPEG lossy compression on the robustness of data hiding methods used for the colour image which has been transformed to the frequency domain. The data have been embedded to the Fourier magnitude spectrum of the image. The possibility of decoding the hidden data with two embedding methods and various parameter values as well as diverse compression rates has also been examined. The paper also contains a short description of the discrete Fourier transform. |
