基于数字水印的即开型彩票防伪探究

Research on anti-counterfeiting of instant lottery ticket based on digital watermarking

数字水印技术是一种有效的信息隐藏技术,通过探究数字水印技术能够实现对即开型彩票(以下简称即开票)的防伪验证,借助哈希算法单向、不可逆的特性结合随机数列生成水印信息,保证数字水印的随机性和安全性。采用DCT水印嵌入算法,通过对比原始水印和从待验证即开票中提取的水印信息的相似性,实现对即开票真伪的鉴定,同时不增加印刷成本。运用数字技术赋能,提高即开票的安全性,推进彩票行业高水平发展。

Digital watermarking technology is an effective information hiding technology, used to realize the anti-counterfeiting verification of instant lottery ticket. By the one-way and irreversible property of Hash algorithm combined with random sequence to generate watermark information, guarantee the randomness and security of digital watermarking. Using DCT watermarking algorithm, by comparing the similarity between the original watermark and the watermark information extracted from the instant ticket,achieve the authenticity of the identification, at the same time does not increase the cost of printing. Using digital technology to improve the security of instant tickets, promote the high-level development of the lottery industry.
