TRUE COLOR ANALYSIS OF PLANT PIGMENT BASED ON IMAGE REALIZATION STEGANOGAPHY TECHNIQUE

Digital steganography is the practice of concealing secret messages behind seemingly normal digital data that does not raise suspicion. This study introduces a novel method of genuine color analysis of plant pigments that resembles a thin film coated on paper chromatography, by analyzing digital images of plant pigments pixel by pixel, we can correlate the color data with the corresponding chromatogram, providing insights into the plant's biochemical composition, referred to as Image Realization Steganography (IRS). This is a mapping-based technique that hides the image cover file in an undetectable manner. The image cover is only intended for reference. The suggested method provides a cover-secret mapping that reveals the true color of a concealed plant pigment without affecting the reference image. Comparing the acquired data to IRS to estimate the true color of Wolffia globosa (L.) Wimm pigment was presented. The conclusions indicate that steganography is a viable option for determining the true color of plant pigments in the form of color codes, specifically RGB and CMYK.
