另外,研究安全秘密共享體制在數字簽名、多方解密中的應用,設計構造了安全有效的密碼演算法。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Though the authorities have publicly admitted to only 300 deaths, they have privately reported 100, 000 mortalities to international agencies, and even that figure is not credible, say experts
專家說中國官方只承認300頭豬死亡,但他們向國際組織秘密報告的死亡率是十萬頭,就算是這個數字也並不可靠。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。Recently, the research of digital watermarking is emphasized, and the stegnaography that is applied to the secret communication is also focused
目前信息隱藏技術大部分的研究工作集中在數字水印技術,而用於秘密通信的隱秘術也逐漸引起人們的興趣。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。On the other hand, the opening and insecure internet brings up a new task to the rfmdms based on the internet that how to ensure the security of data transporting in many application fields such as the military equipments " maintenance and etc. the security of data transporting on the internet is mainly made up of three aspects : identity authentication, encrypted data transporting and digital signature
網路數據傳輸安全主要解決在網路環境下用戶之間身份驗證、數據加密傳輸以及實現數字簽名三個方面問題:用戶身份驗證保證了通信的源點和目的點的正確性;數據加密傳輸保證了數據在網路的中間節點不會泄露通信秘密;數字簽名可以保證發送信息的一方不能對自己發送過的信息進行否認。First, it was strictly platonic till nature intervened and an attachment sprang up between them, till bit by bit matters came to a climax and the matter became the talk of the town till the staggering blow came as a welcome intelligence to not a few evildisposed however, who were resolved upon encouraging his downfall though the thing was public property all along though not to anything like the sensational extent that it subsequently blossomed into
對于為數不少的居心險惡執意要使他垮臺的人們來說,那可是個求之不得的消息。此事一直是個公開的秘密,然而並沒有達到后來渲染成的那樣聳人聽聞的程度。既然他們二人的名字已經連結在一起,既然她已經公開承認他是她的心上人,還有什麼必要從房頂上來向民眾宣布呢?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

提出適合於團體和組織的門限證實數字簽名方案。新方案以乘法秘密共享和rsa加密演算法為基礎,採用一次性零知識證明思想構建簽名的證實協議和否認協議。That is because most digital signatures require the parties in a transaction to have compatible software ? the signer needs to have an encryption algorithm called a “ private key ” on his computer, and everybody else needs a “ public key ” to unlock the signature
這是因為大多數數字簽名要求交易的當事方具有可兼容的軟體,簽名者需要在他的計算機上具有稱為「私人秘鑰」的加密演算法,每個人同時還需要一個「公共秘鑰」來解開簽名。And you need maybe a secret word or a secret number to get in, but we say a password, it ' s the word that lets you pass in, so you would need a password, which of course also might be anything
(上網時)你可能還需要有一個秘密的單詞或數字,我們稱它們為「 password 」 。有了秘碼你才能進入網路,你可以選任何數字字母或詞匯作為你的秘碼。The security of the threshold multiple secret sharing scheme is based on the security of rsa signature, i. e. the difficulty of factoring large integers
門限多重秘密共享方案的安全性依賴于rsa數字簽名的安全性,即大數分解的困難性。Exactly how it uses the web can be syntactically specified as demonstrated in the technical discussion that follows, but that kind of discussion ignores the meta - question of what url to use
