基于差分隐私保护技术的高校贫困生认定系统设计

A Design of Poor Students Identification System in Higher Learning Institutions Based on Differential Privacy

针对目前高校家庭困难学生认定工作中存在的问题,特别是贫困生的隐私无法得到保护的情况。利用目前大部分学校普遍使用的校园卡,对校园卡的消费记录进行整理分析,建立一个科学的评判体系,给出评判指标,通过差分隐私保护技术,对后台的数据进行保护,保证了隐私数据不被泄露。针对不同的实际,设置不同的消费权重,系统可以准确地反映学生的贫困情况,为贫困生的认定提供科学的参考。

As to the problem in identifying poor students in higher learning institutions, especially when the privacy of poor students are not under proper protection, with the application of the common campus card used in many universities, the consumption record is analysied and a scientific evaluation system is set up. The evaluation index is proposed, and through differential privacy protection technology,the background data is protected to ensure the safe private data.With the setting different consumption weight, the system can precisely identify the poverty of students and provide scientific reference to the identification of poor students.
