摘　　要：针对隐私信息频繁交换场景下不可控转发导致的隐私信息泄露问题,提出了一种面向版式文档的细粒度隐私操作控制方法,可实现隐私信息在分享过程中按分享者的要求进行差异化细粒度的隐私操作控制。对接收到的多模态版式文档提取已有隐私操作控制策略,结合当前分享者使用属性、接收者隐私保护能力等因素,迭代生成隐私操作控制策略,并给出了抽象化的控制策略生成算法框架;基于迭代隐私操作控制策略,结合具体操作场景,对不同模态的信息分量进行差异化脱敏控制、交换边界控制和本地使用控制,并给出了抽象化的隐私操作控制算法框架。实验开发了OFD的隐私操作控制前后台原型系统,并对上述方法进行了验证,在即时通信系统中实现了基于好友关系的迭代隐私操作控制策略生成与传递,以及OFD的差异化脱敏控制、交换边界控制和本地使用控制。In view of the problem of privacy information disclosure caused by uncontrolled forwarding in the context of frequent exchange of privacy information,a fine-grained privacy operation control method for layout documents was proposed,which could achieve differentiated fine-grained privacy operation control according to the requirements of the sharer during the sharing process of privacy information.For the received multimodal layout document,the existing privacy operation control strategy was extracted,which combined the current sharer’s use attribute and the receiver’s privacy protection ability and other factors.The privacy operation control strategy was generated iteratively,and an abstract control strategy generation algorithm framework was given.Based on the iterative privacy operation control strategy and combined with specific operation scenarios,the differentiated data-masking control,exchange boundary control and local use control were carried out for different modes of information components,and the abstract privacy operation control algorithm framework was given.A prototype system for privacy operation control of OFD(open fixed-layout document)was developed to verify the above algorithms.The generation and delivery of iterative privacy operation control strategy based on friendship,as well as the differential data-masking control,exchange boundary control and local use control of OFD were implemented in the instant messaging system.
