摘要
【目的/意义】近年来,社交网络服务的隐私关注变得日益严重。先前关于隐私关注的研究大多集中在无差别节点上(仅针对用户行为),但却忽略了用户在社交网络环境中有着长期的社交行为。【方法/过程】创新性地研究了基于隐私关注和社交网络服务与用户双方利益的长期演化博弈,并首次将隐私关注作为一个因素引入到博弈中,通过建立收益矩阵来构建双方利益的演化博弈,最后使用算法进行仿真验算。【结果/结论】实验结果显示:社交网络服务商泄露用户隐私的比例与用户披露隐私信息的比例密切相关;用户的安全收益会提升其对隐私信息披露比例;隐私披露成本有利于提升用户警惕性、减缓隐私信息的泄露,但这种正面影响只在一定范围内有效;加大隐私泄露惩罚力度有利于缓解隐私泄露。
【Purpose/significance】In recent years, privacy concern of social network service is becoming increasingly serious. The previous studies on privacy concern are mostly focused on indiscriminate nodes(only aiming at users' behaviors),but neglectusers' long-term social contact in social network environment.【Method/process】In this paper, the author innovatively makes studies on the long-term evolutionary game of mutual interest between social network service and users on the basis of privacy concern. Moreover, privacy concern is firstly served as a factor to be introduced to game. And the evolutionary game of mutual interest is set up by establishing gains matrix.Finally, software and algorithm are used for simulation checking.【Result/conclusion】The experiment result shows that the proportion that SNS providers disclose users' privacy is closely related to the proportion that users disclose their privacy. Users' security income will increase the proportion that SNS providers disclose their private information. The cost of privacy disclosure is conducive to enhancing users' vigilance and slowing down the disclosure of private information, but it only plays the positive role within limits. The increasing of the punishment intensity on privacy disclosure can be conducive to easing the privacy disclosure.
