In this paper, we propose a new method for authentication, integrity and invertibility of digital images using invertible watermarking. While all watermarking schemes introduce some small amount of non-invertible distortion in the image, the new method is invertible in the sense that, if the image is deemed authentic, the distortion on the extraction procedure can be removed to obtain the original image data. Authentication data is produced from XOR operation between watermark signal and binary bits obtained from a hash function of one block image. If the unmodified watermarked image is used, the extraction process will return the correct watermark signal and exact original image The techniques provide new assurance tools for integrity protection of sensitive imagery such as medical images
