Image steganalysis using image quality metrics : structural contents metric

الملخص EN

A new method presented ٤١١ this work to detect the existence ofhidden data as a secret nies$age images, 'l’his method must be applyied 0ا(1اا on images which have the same visible properties (similar perspective) where the human eyes cannot detect the difference between them.

This method is based on Image Quality Metrics (Structural Contents Metric), which means the comparison betw'een the original images and stego images, and determines the s؛'/.e of the hidden data.

Wc applied the method to four different images, we detect by this method the hidden data and find exactly the same size of the hidden data.
