Digital signature operates the born and a series of sign and codes to constitute the electronics password to carry on the signature through a certain password, replace to the writing signature or an official seals, to confirm the body, the data source and integrities of signs, keeping data from burglarize to take, distort and break, thus to attain the purpose of protecting the data
數字簽名是通過某種密碼運算生成一系列符號及代碼組成電子密碼進行簽名,來代替書寫簽名或印章,確認簽名者的身份、數據來源和完整性,防止數據被竊取、篡改和破壞,從而達到保護數據的目的。Resemble with the digital watermark methods of the other media such as still image and video, digital audio watermark must account for some problems which consist of perceptual transparency, data bit rate, robustness, security and real - time etc. the robustness of watermark is vital to the practical application, which requires the watermark providing with significant data since it suffered from some intended attacks or unintended revisal
與靜態圖像、視頻等數字水印方法類似,音頻水印的研究主要須解決感知透明性、數據嵌入率、魯棒性、安全性以及實時性等問題。水印演算法的魯棒性對于實際應用來說是至關重要的,它要求數字水印在遭受有意的攻擊或無意的修改後,仍能提供有意義的數據,這一性能對版權保護的應用顯得尤為突出。As a new branch of information security, information hiding technology including digital watermarking and steganography aims to protect intellectual property rights of multimedia contents and to send secret messages under the cover of a carrier signal
信息隱藏是信息安全領域中的一項新興技術,主要有數字水印和數字密寫兩大分支,分別用於多媒體數據的版權保護和隱蔽通信。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。In order to implement copyright protection and content authentication of the vq compressed data, the research work of this thesis focuses on the vq based watermarking algorithm
為了實現對矢量量化編碼多媒體數據的版權保護和內容認證,本文研究基於矢量量化的數字水印演算法。Among the possible approaches to the protection of copyrighted data, digital watermarking is receiving increasing attention, as it represent a viable solution to data protection in open, highly uncontrolled, environments where cryptographic techniques cannot be applied successfully
在可能用於保護有版權的數據的方法中,數字水印已經受到越來越多的關注,因為它提供了一種在開放的,不可控制的環境中可行的數據保護方法,這是加密技術所不能做到的。In order to improve the robustness of digital watermarking for copyright protection, a novel position and method complementary embedding algorithm is proposed, which is based on the analysis of the unbalanced characteristics for different image processing methods
摘要為提高用於版權保護的數字水印的魯棒性,基於圖像小波信號分析方法,分析了各種處理攻擊對圖像小波系數影響的不均衡特性,並根據該特性提出嵌入位置和嵌入方法互補的新穎水印演算法。Printing, data - protection
