Sažetak
In this paper we developed a steganographic method for image protection on Facebook social network. The method hides additional information such as a logo or serial number. Uploading the images on the social network has induced image degradation on the original images. Based on the analysis of this attack we developed a method based on the discrete cosine transform - DCT where additional information is hidden by modifying the coefficients in the cosine domain. The method was evaluated and it is show that bit error rate (BER) for different attacks was below 1%.
