摘要
为实现对二维码的分权限读取,提出一种二维码应用框架。通过在二维码中嵌入隐藏信息,使一般用户可采用标准软件读取公开信息,高权限用户通过定制软件读取机密信息;基于该框架,提出针对QR二维码的两种信息嵌入算法,即整体嵌入算法和分散嵌入算法。实验和分析结果表明,这两种算法在安全性、鲁棒性和计算效率方面能够满足一般应用需求,可在政府、商业和社会领域中实际应用。
A systematic framework based on 2 Dcode was proposed,so that different contents could be fetched from the same 2 D code depending on users’ authorities.Specifically,general users could only access public information via standard decoder,while users with higher authorities could access confidential information via customized decoder.Two information hiding algorithms,namely,holistic algorithm and scattered algorithm,were proposed using the proposed application framework.Results of experiments and analyses show that both algorithms can satisfy the requirements of security,reliability and efficiency,which can be applied to deal with affairs of government,commerce and society.
