ipsec在網(wǎng)絡(luò)層發(fā)揮作用，對傳輸?shù)膇p包進行保護和認證，它提供了在internet這樣無保護的網(wǎng)絡(luò)中傳送敏感信息的安全保證。 - the paper analyses the extranet's safe plan through weightiness, the factors that should be considered, goal establishment . the keystone is the safe technology that is used in data confidentiality, data integrality, data authentication
在分析外聯(lián)網(wǎng)安全計劃時，主要從外聯(lián)網(wǎng)安全計劃的重要性、制定外聯(lián)網(wǎng)安全計劃應(yīng)考慮的因素、航交所外聯(lián)網(wǎng)安全計劃目標的制定三方面來論述。 - 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(shù)字水印是指嵌入到多媒體數(shù)據(jù)中的信息,可以是數(shù)字、序列號、文字、圖像標志等各類信息,以起到版權(quán)保護、標志產(chǎn)品、秘密通信、證實數(shù)據(jù)歸屬權(quán)、鑒別數(shù)據(jù)真?zhèn)蔚茸饔谩?/li> - the research and the development on video frequency watermark are quite rapid, but its application is not that mature compared with the text watermark and the image watermark, its application mainly manifests in the following aspects : for instance, copyright protection, digital fingerprint, copy protection, broadcast monitoring, data authentication, title and indexing, safe covert communication and so on . from the studies on algorithm, there are also many relatively mature video frequencies watermarks algorithm at present, as stated in the text, but most of the research on watermark algorithm has not integrated with the practice application
在論文中,我們主要針對廣播監(jiān)控中的兩種應(yīng)用,即數(shù)字電視信號監(jiān)控和廣告監(jiān)控,分別提出了兩個可行的解決方案,并將之與水印技術(shù)相結(jié)合,分別實現(xiàn)了非壓縮域和壓縮域的水印方案。文中還就系統(tǒng)的具體實現(xiàn)進行了簡單的分析,并提出了一些可行的改進方向。在進行視頻水印實現(xiàn)之前,本文先針對圖像水印進行了必要的模擬實驗,進而分別針對壓縮和非壓縮兩種情況進行了視頻模擬實驗。 - for data authentication, we propose a wavelet based fragile watermarking algorithm, which takes full advantage of characters of a wavelet, limits the minimum distance between the value of coefficients and quantization boundary, and uses our method to round image pixels to integer values to form a digital image
