Abstract: Current methods of embedding hidden data in an image inevitably distort the original image by noise. This distortion cannot generally be removed completely because of quantization, bit-replacement, or truncation at the grayscales 0 and 255. The distortion, though often small, may make the original image unacceptable for medical applications, or for military and law enforcement applications where an image must be inspected under unusual viewing conditions (e.g., after filtering or extreme zoom). The present invention provides high-capacity embedding of data that is lossless (or distortion-free) because, after embedded information is extracted from a cover image, we revert to an exact copy of the original image before the embedding took place. This new technique is a powerful tool for a variety of tasks, including lossless robust watermarking, lossless authentication with fragile watermarks, and steganalysis. The technique is applicable to raw, uncompressed formats (e.g., BMP, PCX, PGM, RAS, etc.), lossy image formats (JPEG, JPEG2000, wavelet), and palette formats (GIF, PNG).
Abstract translation: 将隐藏数据嵌入到图像中的当前方法不可避免地使原始图像由噪声失真。 由于在灰度0和255处的量化，位替换或截断，这种失真通常不能被完全去除。失真尽管经常很小，但可能会使原始图像对于医疗应用或军事和执法应用而言是不可接受的，其中 必须在异常观看条件下检查图像（例如，过滤或极大变焦后）。 本发明提供了无损（或无失真）的数据的高容量嵌入，因为在从封面图像提取嵌入信息之后，在嵌入发生之前，我们恢复原始图像的精确拷贝。 这种新技术是用于各种任务的强大工具，包括无损鲁棒水印，易损水印的无损认证和隐写分析。 该技术适用于原始的未压缩格式（例如，BMP，PCX，PGM，RAS等），有损图像格式（JPEG，JPEG2000，小波）和调色板格式（GIF，PNG）。
