Description: 经典的利用SVD进行数字图像水印的嵌入与提取,代码完整,可以运行,自带测试图像。
数字水印(Digital Watermarking)技术是将一些标识信息(即数字水印)直接嵌入数字载体(包括多媒体、文档、软件等)当中,但不影响原载体的使用价值,也不容易被人的知觉系统(如视觉或听觉系统)觉察或注意到。通过这些隐藏在载体中的信息,可以达到确认内容创建者、购买者、传送隐秘信息或者判断载体是否被篡改等目的。数字水印是信息隐藏技术的一个重要研究方向。
-The classic use of SVD digital image watermark embedding and extraction, the code is complete, you can run, comes with a test image. Digital watermark technology (Digital Watermarking) is the identification information (digital watermark) is embedded directly into the digital carrier (including multimedia, documentation, software, etc.) does not affect them, but the value in use of the original carrier, is not easy to be the human perception system ( such as visual or auditory system) perceived or noticed. Can be achieved through these information hidden in the carrier confirm the content creator, purchase, transmit secret information, or to judge the carrier has been tampered with such purposes. The digital watermark is an important research direction of information hiding technology. Platform: |

Description: This paper presents a novel algorithm of hiding
secret messages by applying mathematical lemmas and
information theory. The proposed algorithm can hide more
information with acceptable embedded rate and achieves
requirements of information hiding algorithm and simply
information extracting. The main idea is applying modern
algebra to solve the information hiding problem in multimedia.
In order to prevent some attacks on stganography, hidden
initial bits of image data pixels are chosen randomly. The
extracted information are achieved without the reference of the
original image and extracted keys. The experiment results
show that our approach is effective and reliable.-This paper presents a novel algorithm of hiding

Description: propose a novel joint data-hiding
and compression scheme for digital images using side match
vector quantization (SMVQ) and image inpainting. The two
functions of data hiding and image compression can be integrated
into one single module seamlessly. On the sender side, except for
the blocks in the leftmost and topmost of the image, each of the
other residual blocks in raster-scanning order can be embedded
with secret data and compressed simultaneously by SMVQ or
image inpainting adaptively according to the current embedding
bit. Vector quantization is also utilized for some complex blocks
to control the visual distortion and error diffusion caused by the
progressive compression. After segmenting the image compressed
codes into a series of sections by the indicator bits, the receiver
can achieve the extraction of secret bits and image decompression
successfully according to the index values in the segmented
sections. Experimental results demonstrate the effectiveness of
the proposed scheme. Platform: |

Description: Advances in formation technology have gradually changed people’s lives and lifestyles in recent years. The Internet provides a convenient environment for users to exchange secret data or communicate with one another regardless of their physical locations. Telemedicine is a well-known application, where enormous amount of medical data need to be securely transferred over the public network and manipulate effectively. If the information is accessed by unauthorized person, it may lead to malicious attack or any alteration of medical image may result in misdiagnosis. Thus to ensure the patient’s data integrity, recently several researchers have applied data hiding technique named steganography, since it is an appropriate tool to be used for enhancing security and authentication of medical data.-Advances in information technology have gradually changed people’s lives and lifestyles in recent years.
