【摘要】：隨著市場經(jīng)濟的不斷發(fā)展,圖書盜版泛濫成災(zāi),嚴重的損害了生產(chǎn)者和消費者的合法利益。縱觀我國目前的圖書防偽技術(shù)大概有數(shù)碼防偽和激光全息防偽技術(shù)。數(shù)碼防偽雖然其成本不高,但查詢需要支付額外的費用。據(jù)不完全統(tǒng)計,數(shù)碼查詢率很低(不足5%),這恰好給造假者提供了盜版的機會。激光全息防偽技術(shù)消費者識別比較困難,而且激光編碼機造價昂貴,中小企業(yè)難以采用,一旦造假者擁有了這種裝備,其防偽作用立即失效。 二維碼技術(shù)是在一維碼基礎(chǔ)上發(fā)展起來的一種自動識別技術(shù),隨著智能手機的不斷發(fā)展,二維碼技術(shù)在世界各國得到了廣泛應(yīng)用。二維碼相對于一維碼,具有存儲容量大、編碼范圍廣、容錯能力強、譯碼可靠性高并可以引入加密措施等特點。二維碼的特點使它能夠廣泛應(yīng)用于各種防偽領(lǐng)域,本文應(yīng)用于圖書防偽研究。 本文針對現(xiàn)有防偽技術(shù)的不足,采用QR二維碼為存儲信息的載體并結(jié)合RSA公鑰加密技術(shù),研究與實現(xiàn)了一個以圖書防偽為實例的防偽系統(tǒng),實現(xiàn)了QR二維碼的生成、識別和信息加密等模塊功能。防偽流程是對每本圖書相關(guān)信息的錄入后,然后采用RSA的公鑰對唯一編號編碼進行加密并生成二維碼圖片,將此二維碼圖片標貼于圖書的合理位置,最后消費者通過掃描二維碼圖片得到密文,通過系統(tǒng)私鑰解密查詢來確定圖書的真?zhèn)巍?br/>[Abstract]:With the continuous development of market economy, book piracy is rampant, which seriously damages the legitimate interests of producers and consumers. Throughout the current book anti-counterfeiting technology in China, there are probably digital anti-counterfeiting and laser holographic anti-counterfeiting technology. Although the cost of digital anti-counterfeiting is not high, but the query needs to pay an additional fee. According to incomplete statistics, the digital inquiry rate is very low (less than 5%), which happens to provide counterfeiters with the opportunity to pirate. It is difficult to identify consumers of laser holographic anti-counterfeiting technology, and the cost of laser coding machine is expensive, so it is difficult for small and medium-sized enterprises to adopt it. Once the counterfeiter has this kind of equipment, its anti-counterfeiting effect will fail immediately. QR code technology is a kind of automatic recognition technology developed on the basis of one-dimensional code. With the continuous development of smart phone, QR code technology has been widely used in the world. Compared with one-dimensional code, QR code has the characteristics of large storage capacity, wide coding range, strong fault-tolerant ability, high decoding reliability and can introduce encryption measures. The characteristics of QR code make it widely used in various anti-counterfeiting fields. This paper is applied to the research of book anti-counterfeiting. In this paper, aiming at the shortcomings of the existing anti-counterfeiting technology, using QR code as the carrier of storing information and RSA public key encryption technology, an anti-counterfeiting system with book anti-counterfeiting as an example is studied and implemented, and the generation of QR code is realized. Identification and information encryption and other module functions. The anti-counterfeiting process is to use the public key of RSA to encrypt the unique number code and generate the QR code picture after inputting the relevant information of each book, and affixing the QR code picture to the reasonable position of the book. Finally, the consumer obtains the ciphertext by scanning the QR code picture, and determines the authenticity of the book by decrypting the private key of the system.
