Abstract: | A system for the insertion and retrieval of marks has been implemented in this work, and this has allowed this process to be carried out with a specific kind of image (images in JPEG format). The correct implementation of the system has enabled tests of the insertion and retrieval of marks in JPEG images. A study has been effected of the robustness of the system in the face of manipulations by compression that aim to eliminate the frame, and it has been shown that the implemented system offers a greater robustness in grayscale images than in color images. |
