Privacy preserving technology had addressed the problem of privacy leakage during data publishing proc-ess,however,current data publishing technologies mostly focused on publishing privacy preserving data with single level,without considering some scenarios of multi-level users.Therefore,a differentially-private mechanism for multi-level data publishing was proposed.The proposed mechanism employed the Laplace mechanism with different privacy budgets to output results with different privacy protection levels.After the user’s level was determined ac-cording to the charge or privilege of that specific user,the goal that a user with high(low) level can only use the out-put result with low(high) privacy protection level which had low(high) error rate could be achieved.Finally,the evaluation results and security analysis show that our proposed framework can not only prevent from background knowledge attack,but also achieve multi-level data publishing with different error rates effectively .

To solve the problem that traditional traffic abnormal detection methods were not accurate enough,a traf-fic anomaly detection method based on improved k-means was proposed.All kinds of network traffic data were pre-processed to make k-means algorithm can apply to enumeration data detection.Then a features selection method was pro-posed with the analysis of the distribution of network traffic data to avoid the distance useless caused by too much fea-tures.Furthermore,the clustering process of K clusters was optimized based on dichotomy,aiming to reduce the effects of initial clusters centers selection.Simulation results demonstrate the effectiveness of the algorithm.

Recently,wearable devices acted as a kind of smart devices are changing people’s life style.When these devices are used in multi-user setting,ownership transfer should usually be considered.To resolve the security and privacy problems introduced in the ownership transfer process of wearable devices,a secure ownership transfer pro-tocol including initialization,mutual authentication and key change for wearable devices was introduced.The secu-rity analysis indicates that the proposed protocol can resist either normal channel attacks or special attacks appeared in the ownership transfer scenarios.The experiment results indicate that the proposed scheme is fairy efficient and is quite suitable for wearable devices.

Given its high utility value,mobile social network services(MSNS),however,has raised serious concerns about users’ location privacy.The location privacy requirements of users in MSNS are personal and dynamic,thus a metric called confidence was proposed to quantify the privacy risks.To avoid the adversary inferring users’ privacy,a method of legation privacy protection was designed to calculate the correlation between the locations through lo-cation information,social relation and personal information.Then the correlation and the space-time background were used to evaluate whether the users’ published geo-content meet the user’s privacy requirement.Eventually,our experimental results demonstrate the validity and practicality of the proposed strategy.

The internet governance and legislation have experienced the free development,the exploration and the comprehensive stages.There are some problems about the current legislation,such as the law level is low,the high-level law is lack,the legislation is relatively scattered,legislation is lagging far behind the technology,the cur-rent law is principle and lack of the operability,legislation is heavy duty,light-rights,and so on.According to these conditions,accelerating the basic legislation,such as the cyber security law,the personal information protection act,the internet service administration law,the act of e-commerce,the e-government law,the telecommunications act,and so on was suggested,so as to build a relatively complete cyber law system.
