Loss of personal data or leakage of corporate data via apps on mobile devices poses a significant risk to users. It can have both a huge personal and financial cost. This work is designing new novel techniques to help reduce the risks for end-users who use a single device for multiple spheres of activity. Getting security right when a single device is used for multiple spheres of activity is a major research challenge, with unforeseen information flows between various subsystems that are currently difficult to control. This project is developing mechanisms to better manage flows between apps on a mobile device so that users are able to compartmentalize different spheres of activity, such as work and personal use.Broader impact: This research benefits both end-users who are concerned about the privacy of their data on mobile devices as well as businesses who wish to permit use of mobile devices for improving efficiency of their operations but are concerned about resulting security risks. Graduate and undergraduate students are trained in the area of security and privacy of information on mobile devices.

通过移动的设备上的应用程序丢失个人数据或泄露公司数据会给用户带来重大风险。这可能会带来巨大的个人和经济成本。这项工作正在设计新的新颖技术，以帮助降低使用单一设备进行多个活动领域的最终用户的风险。 当单个设备用于多个活动领域时，获得安全性是一项重大的研究挑战，目前难以控制的各种子系统之间的不可预见的信息流。该项目正在开发更好地管理移动终端上应用程序之间流量的机制，以便用户能够区分不同的活动领域，例如工作和个人使用。这项研究对双方都有好处-关注其在移动的设备上的数据隐私的用户以及希望允许使用移动的设备以提高其运营效率但关注以下问题的企业造成安全风险。研究生和本科生在移动的设备上的信息的安全和隐私领域进行培训。
