Abstract
In this paper, a steganographic method for hiding data in JPEG Image is proposed. This technique uses the Quantization Error Table(QET) resulting from processing the discrete cosine transformed image with quantization and dequantization which is used for selecting the positions for hiding secret bits in the image. The proposed steganograpic method can provide a high information hiding capacity and successfully increase the security.
