摘要
为了提高公司间公文频繁传输的防伪能力,本文提出一种基于多重图像隐藏标识的蚁群算法,利用傅里叶级数、K-mean处理和Metropolis接受准则进行公文中相关数据进行判断,并在三维多重图形中插入隐藏图形方式,以提高公文标识的防篡改能力。同时,本文对防伪标识的防伪原来,分析标识被篡改、替换的原因,总结防伪标识的特征,提出多重图像防伪的设计思路和处理方法,并通过实际案例的试验,验证该处理方法的正确性、图像间拟合性及防伪程度。MATLAB仿真结果显示,多重图像隐藏算法的防伪标识的拟合度较好,防伪程度在98%以上,而且防篡改程度先上升后下降,整体指标较佳,优于二维多重图像的防伪性。因此,本文提出的多重图像隐藏防伪标算法,适用于在公司数字化转型阶段的公文防伪标识优化。
In order to improve the anti-counterfeiting ability of frequent transmission of official documents between companies, this paper proposes an ant colony algorithm based on multiple image hidden identification, uses Fourier series, K-mean processing and metropolis acceptance criteria to judge the relevant data in official documents, and inserts hidden graphics into three-dimensional multiple graphics to improve the anti-tampering ability of official document identification. At the same time, this paper analyzes the reasons for the tampering and replacement of the anti-counterfeiting logo, summarizes the characteristics of the anti-counterfeiting logo, puts forward the design idea and processing method of multi image anti-counterfeiting, and verifies the correctness of the processing method, the fitting between images and the degree of anti-counterfeiting through the test of actual cases. Matlab simulation results show that the fitting degree of the anti-counterfeiting logo of the multi image hiding algorithm is better, the anti-counterfeiting degree is more than 98%, and the anti tampering degree increases first and then decreases. The overall index is better, which is better than the anti-counterfeiting of two-dimensional multi images. Therefore, the multi image hiding anti-counterfeiting algorithm proposed in this paper is suitable for the optimization of official document anti-counterfeiting identification in the digital transformation stage of the company.
