Overcoming the effect of JPEG compression on steganography

الملخص EN

n§ a novel coding scheme to overcome؛This work presents an effective approach us the errors caused by JPEG (Joint Photographic Expert Group) compression.

The proposed novel coding technique (distance-to-origin) depends on viewing the pixel as a point in space with the three color channel values as the coordinates in the is used as steganography to improve the quality of the image at ال.spatial domain the receiving end.

In this work, data (text and various images) was hidden within three different covers using the Least Significant Bit (LSB) coding technique and the novel coding technique (distance-to-origin), and then a JPEG compression-or each؛ decompression was applied.

The error percentage were steganography/compression was computed and then analyzed.

Comparison made tor different types of steganography/compression with and without using the ,proposed approach to show the correctness and consistency ofthis work
