The advent of the internet and the wide availability ofcomputers, scanners and printers make digital data acquisition, exchange and transmission a simple task. however, making digital data accessible to others through networks also creates opportunities for malicious parties to make salable copies of copyrighted content without permission of the content owner. digital watermarking is likely to be a potential solution to this problem. digital watermarking has been proposed as a solution to the problem of copyright protection of multimedia documents in networked environments. it makes possible to embed a watermark ( such as identification data, serials number, text or image etc. ) to multimedia documents allowing copyright protection, secret communication, document authentication and so on. in this paper, we present a new digital image watermarking method based on svd ( singular value decomposition ), and then give some theoretical analysis about the algorithm. extensive experimental results show that this method is much more robust than other methods presented before
隨著計算機和網路技術的飛速發展,數字圖像、音頻和視頻產品愈來愈需要一種有效的版權保護方法,另外通信系統在網路環境下的信息安全問題也日益顯露出來.數字圖像水印技術為上述問題提供了一個潛在的解決方案.所謂水印技術就是將數字、序列號、文字、圖像標志等版權信息嵌入到多媒體數據中,以起到版權保護、秘密通信、數據文件的真偽鑒別和產品標志等作用.本文提出了一種新的基於奇異值分解的數字水印演算法並且對該方法的理論基礎給出分析.實驗結果表明這種方法要比目前提出的流行演算法魯棒In chapter 2, a general digital watermarking frame is presented, including the generation, embedding and detection of watermark. in chapter 3, the concept of watermarking channel is presented, the modes of watermarking channel and image dct coefficients is proposed, the capacity of watermarking channel is evaluated by embedding watermarks to selected still image dct coefficients in direct spread spectrum. in chapter 4, a watermarking algorithms based wavelet multi - resolution is presented, by conjunction with human visual model, it keeps invisibility of watermark in host image and need not original image during detection
數字水印是一種新的數字媒體保護技術,它是將特定的信息(如版權信息、秘密消息等)嵌入到圖象、語音、視頻等各種數字媒體中,以達到版權保護等目的,同時,這種信息對宿主媒體的影響不足以引起人們的注意且有特定的恢復方法,此信息對非法接收者應該是不可見的,本文主要對數字水印的一般框架,靜止圖象dct系數的理論容量,圖象水印的嵌入和檢測,數字媒體防篡改以及數字水印的攻擊等問題進行了研究,提出了兩個新的水印算演算法。At present time, most of the studies focus on digital watermarking techniques, and few are done on steganography, one of the most important directions in the field of information hiding
目前大部分的研究工作集中於數字水印技術,而用於秘密通信的掩密術則較少有人涉及。本文對信息隱藏領域的另一個重要方向? ?掩密技術進行了研究,著重討論了其在數字圖像中的應用。Digital watermarking is the technology which embeds copyright information including product id, text content or image logo into multimedia for copyright protection, secret communication and discrimination of the data files
所謂數字水印技術就是將數字信息如產品序列號、文本內容、圖像標志等版權信息嵌入到多媒體數據中,以起到版權保護、秘密通信、數據文件的真偽鑒別等作用。Digital watermarks may be all kinds of information which can be embedded into multimedia data, just as digits, serial numbers, text, image symbols, so it can be used in copyright protection, marker production, covert communication, data ownership confirmation, data authentication
數字水印是指嵌入到多媒體數據中的信息,可以是數字、序列號、文字、圖像標志等各類信息,以起到版權保護、標志產品、秘密通信、證實數據歸屬權、鑒別數據真偽等作用。Believed to be created by women, was a secret script used exclusively among women in shangjiangxu township, jiangyong county, hunan province, china
那稀奇秘密的文字,指的是在湖南省江永縣上江墟鄉據稱由女性創造的書寫文字,只在女性間唱誦流傳,稱為女書。The message to be transferred can be image or text file, and can be hided in the space domain or frequency domain of the image
這些要傳輸的秘密信息可以是文字信息也可以是圖象信息,隱藏的位置可以是圖象的空間域或頻率域內。She had been offered to the world, these seven years past, as the living hieroglyphic, in which was revealed the secret they so darkly sought to hide - all written in this symbol - all plainly manifest - had there been a prophet or magician skilled to read the character of flame
過去這七年裡,她作為如同有生命的象形文字,被奉獻給人類社會,在她身上揭示了他們竭力要隱藏的秘密,要是有一位先知或法師有本領破解這個火焰般的文字的話,就會懂得一切全都寫在這個象徵之中,一切全都顯示得明明白自!I think all these are closely related to the job of a junior secretary because it requires the ability to perform general office work and to assist the manager in handling all paper work
應:我想這些課程和高級秘書的工作密切相關,因為高級秘書要求一般辦公室操作及協助經理進行文字工作的能力。A : i think all these are closely related to the job of a junior secretary because it requires the ability to perform general office work and to assist the manager in handling all paper work
應:我想這些課程和高級秘書的工作密切相關,因為高級秘書要求一般辦公室操作及協助經理進行文字工作的能力。In recent years, some new concepts of information security have been proposed, especially in the application of intellectual property right protection, copyright protection and tamper - proofing. information hiding and digital watermarking are new measures of digital media protection, which are processes of embedding hidden messages within digital media such as text, images, video and audio. the hidden messages could be copyright information, user distributor identification number, company logo, personal signature, control bits, or any information considered useful for a specific application
信息隱藏與數字水印技術就是一種新的數字媒體保護措施,它是將特定的信息(如版權信息、秘密消息等)嵌入到圖像、語音、視頻及文本文件等各種數字媒體中,以達到標識、注釋及版權保護等目的,同時,這種信息對宿主媒體的影響不足以引起人們的注意且具有特定的恢復方法,此信息對非法接收者應該是不可見、不可察覺的。The paper designs a data encryption system for network communication, which combines the private - key algorithm 3des with the public - key algorithm rsa to encrypt data and signs on files with public - key algorithm rsa and one - way hash function md5. the system can actualize encryption of data, digital signature and identification efficiently and ensure privacy, authenticity, integrity and nonrepudiation of data
在此基礎上,本文設計了網路通信數據加密系統,該系統將對稱加密演算法3des與非對稱加密演算法rsa相結合對數據加密,用公鑰演算法rsa和單向散列函數md5實現對文件的數字簽名,有效地實現了網路通信系統中的信息加密、數字簽名、身份認證等功能,保證了發送方所發送信息的秘密性、鑒別性、完整性及不可否認性。Give precise criterions and descriptions of some important concepts and disposals of data - hiding technique such as cover, stego - object, hiding information, data embedding, data extraction, stego - key, stego - analysis, insensibility, covert communication, digital watermarking, robustness and etc. then propose a general mathematical model of data hiding which cover most models proposed in other papers and establish the basis for further theory analysis
