This project is focused on a potentially transformational research study involving the simultaneous investigation of usability and security/privacy technologies for location-based geo-social applications, with the objective of studying the usability, feasibility, and scalability of privacy-preserving and secure location-aware geo-social networking platforms for mobile devices. The approach is based on a belief that usability and security/privacy are addressed properly and most effectively from the start. In particular, the project will study the usability of privacy-agile secure location-based communication and associated supporting protocols that scale to large numbers of users and accommodate various privacy levels suitable for different application domains. By studying the usability of location-aware protocols, the investigators propose methods that provide seamless connectivity and functionality over different networking technologies, without sacrificing the user experience. The investigators also plan to address other security issues in privacy-preserving operation, including authentication, access control and accountability. This project envisions a wide range of future applications with three unifying factors: (1) a geo-social undertone, i.e., applications that combine social groups and locality, (2) lack of, or desire to avoid using, fixed infrastructure facilities, and (3) need for both security and privacy. Although progress is starting on technologies for supporting such applications, there has been precious little work done on the study of usability factors with respect to the privacy and security users expect with their small-device location-based applications. The proposed project therefore has an ambitious goal: to study the usability of privacy-preserving geo-social technologies, including the user models, perceptions, interfaces, and feasible communication/computation technologies for supporting futuristic geo-social applications on portable mobile devices in the aforementioned setting. Methods employed may include interviews, focus groups, and cognitive walkthroughs. One key feature of the approach is to study methods that shield location from identity, thereby allowing for location-based services and geo-social applications while also protecting user privacy, and, most importantly, to do so in a way that is most usable and effective from the user?s point of view.Technologies using location and small devices are growing at a rapid rate, while techniques considering security and location and identity privacy are only now being addressed. Thus, usable systems that protect location-sensitive privacy concerns could have a major impact on society. The tools developed in this project will enable important and economically beneficial technologies to be developed for location-aware geo-social networks preserving privacy rights for the individuals using such services. In addition, a vital part of this project involves graduate-student participation in research. Thus, this project has the potential of bringing expanded research opportunities for developing the next generation of information technology researchers. Likewise, it also includes an important educational component.

该项目的重点是一个潜在的转型研究，涉及的可用性和安全/隐私技术的同时调查基于位置的地理社会应用程序，研究的可用性，可行性和可扩展性的隐私保护和安全的位置感知地理社会网络平台的移动的设备的目标。这种方法是基于这样一种信念，即从一开始就正确且最有效地解决可用性和安全性/隐私问题。特别是，该项目将研究隐私敏捷安全基于位置的通信和相关支持协议的可用性，这些协议可扩展到大量用户，并适应不同应用领域的各种隐私级别。通过研究位置感知协议的可用性，研究人员提出了在不同网络技术上提供无缝连接和功能的方法，而不会牺牲用户体验。调查人员还计划解决隐私保护操作中的其他安全问题，包括身份验证、访问控制和问责制。该项目设想了未来广泛的应用，具有三个统一因素：（1）地理社会背景，即，结合了联合收割机社会群体和地点的应用，（2）缺乏或希望避免使用固定的基础设施，以及（3）需要安全和隐私。虽然支持此类应用程序的技术正在取得进展，但在研究用户对小型设备基于位置的应用程序的隐私和安全性方面的可用性因素方面，几乎没有做过任何工作。因此，拟议的项目有一个雄心勃勃的目标：研究隐私保护地理社会技术的可用性，包括用户模型，感知，界面和可行的通信/计算技术，以支持未来的地理社会应用程序的便携式移动的设备在上述设置。所采用的方法可能包括访谈，焦点小组和认知步行。该方法的一个关键特征是研究屏蔽身份的位置的方法，从而允许基于位置的服务和地理社会应用程序，同时也保护用户隐私，最重要的是，这样做的方式是最有用的和有效的用户？使用定位和小型设备的技术正在快速增长，而考虑安全性、位置和身份隐私的技术现在才得到解决。因此，保护位置敏感隐私问题的可用系统可能会对社会产生重大影响。该项目中开发的工具将为位置感知地理社交网络开发重要且具有经济效益的技术，为使用此类服务的个人保护隐私权。此外，该项目的一个重要组成部分涉及研究生参与研究。因此，该项目有可能为培养下一代信息技术研究人员带来更多的研究机会。同样，它还包括一个重要的教育组成部分。
