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.

该项目的重点是一项潜在的转型研究研究，涉及基于位置的基于位置的地理社会应用的可用性和安全性/隐私技术的同时研究，目的是研究隐私提供的可用性，可行性和可扩展性，并具有安全性的位置意识到的地理位置 - 与移动设备的地理社会网络平台。该方法是基于一种信念，即从一开始就可以正确，最有效地解决可用性和安全/隐私。特别是，该项目将研究基于位置的安全性通信和相关的支持协议的可用性，这些协议扩展到大量用户，并适应适合不同应用程序域的各种隐私级别。通过研究位置感知协议的可用性，研究人员提出了在不同的网络技术上提供无缝连通性和功能的方法，而无需牺牲用户体验。调查人员还计划解决隐私操作中的其他安全问题，包括身份验证，访问控制和问责制。该项目设想了有三个统一因素的各种未来应用：（1）一个地理社会底色，即结合社会群体和地方性的应用，（2）缺乏或避免使用固定基础设施设施，以及（3）安全和隐私的需求。尽管在支持此类应用程序的技术方面开始进展，但是在研究可​​用性因素方面，关于隐私和安全用户对其基于位置的小型应用程序期望的可用性因素的工作很少。因此，拟议的项目具有一个雄心勃勃的目标：研究保护隐私的地理社会技术的可用性，包括用户模型，感知，接口和可行的通信/计算技术，以支持在审议设置中便携式移动设备上的未来性地理社会应用。采用的方法可能包括访谈，焦点小组和认知演练。该方法的一个关键特征是研究将位置避免身份的方法，从而允许基于位置的服务和地理社会应用程序，同时还可以保护用户隐私，最重要的是，以一种最可用且最有效的方式从用户角度来看。技术和小型设备使用位置和小型设备的发展速度和确定性，仅在技术和身份方面依赖，并且仅在技术方面增长。因此，保护​​对位置敏感的隐私问题的可用系统可能会对社会产生重大影响。该项目开发的工具将使重要且经济上有益的技术能够开发出对位置感知的地理社会网络，从而为使用此类服务​​的个人保留隐私权。此外，该项目的重要组成部分涉及研究生参与研究。因此，该项目有潜力为发展下一代信息技术研究人员带来扩展的研究机会。同样，它还包括一个重要的教育组成部分。
