在线传输电子文档图像脱敏系统设计与实现

Design And Implementation Of Image Masking System For Online Transmission Of ElectronicDocuments

伴随着网络传输的高效便捷,个人隐私信息泄露等问题也是屡见不鲜。较之普遍的文字敏感信息,图像中所涵盖的隐私信息也不容忽视,例如电子文档内嵌的个人证件图像等。在文本信息的数据脱敏技术日益完善的同时,隐私图像数据泄露的问题亟待解决。着眼于生活工作中网络传输的电子文档中包含图像的电子文档脱敏需求,在研究HTTP协议、Word文档二进制格式和图片格式的基础上,结合HTTP协议解析、文档解析以及图片解析,利用网络数据包的抓取、修改和传输等操作,提出了一种在线传输电子文档图像脱敏技术解决方案。

Along with the efficient and convenient network transmission,personal privacy information disclosure becomes a serious problem.Compared with the privacy text information,the privacy information residing in image file becomes even more sensitive,such as the image of the personal ID embedded in the electronic documents.In addition to the privacy content masking of plain text,the problem of privacy image data leakage needs to be solved as well.Therefore,this paper focuses on the privacy preservation technique for the daily electronic documents delivered via the network.On the basis of the HTTP protocol,Word binary file format and the image format for we propose an online transmission image data masking,we propose an online transmission image data masking technique,which comprises of the online packet capturing,privacy preservation masking based modification and network encapsulation and transmission.And our analysis shows that it provides a preliminary but promising solution to fulfill the online image masking requirements.
