  • Method and system for protecting data using steganography
    Patent number: 10008132
    Abstract: A method and apparatus for embedding a data message in a carrier object using steganography. The method provides a secret key and determines an indicator channel from a plurality of color channels in the carrier object, wherein the indicator channel is the color channel in the carrier object that has a maximum number of different pixel values in the carrier object. The method generates a sorted indicator channel value array based on the channel values and the frequency of occurrence of each value of the indicator channel in the carrier object. For each indicator channel value in the sorted indicator channel value array, the method iterates through the carrier object to determine the pixel in the carrier object whose indicator channel value is the same as the current indicator channel value in the sorted indicator channel value array.
