L2M NSERC - PrivyTo: Location Privacy Reimagined

人们对个人位置隐私的关注达到了前所未有的高度，但与朋友、家人和公众分享生活的愿望仍然存在。在线服务不断要求用户通过他们的移动的设备分享他们的位置，迫使他们权衡分享这些信息的成本和可能的收益。用于共享位置内容的当前平台（例如，谷歌，Facebook）与我们生活中的人的范围是非常缺乏的。大多数网站都为用户提供了一个选择：要么与他人分享你的精确地理坐标，要么根本不分享你的位置。即使像Twitter和Instagram这样的应用程序也只提供有限的地理标记内容选项，通常仅限于附近的景点或当前城市。这些有限的选择并不能反映存在的广泛的个人、职业和社会关系。一个人在与熟人分享自己的位置时的舒适程度与与他们的配偶有很大不同。 此外，共享过程通常涉及允许大型商业公司访问您的位置，然后才能将其传输给预期的接收者。对于许多人（特别是处于风险中的个人）来说，通过这些有限的选择之一公开共享个人位置信息的想法是非常令人担忧的。 PrivyTo是一个平台，让个人重新控制他们的个人位置隐私，允许他们自由地安全地分享他们的位置，并具有不同程度的隐私。我们的方法是建立在混淆和加密的位置视图的新想法，并促进了一个独特的开放的共享方法。 用户可以与各种个人（例如，家人、朋友、公众）。 不同的钥匙解锁他们的位置的不同视图。 公众可以看到我现在所在的城市，朋友可以看到我的邻居，我的家人可以获得我的精确地理坐标。 整个过程是端到端加密的，因此没有第三方应用程序可以访问个人的位置。 本提案旨在资助与本项目理念相关的创业教育和市场研究。

Concern over the privacy of one's personal location is at an all-time high, yet the desire to share our lives with friends, family, and the public persists. Online services constantly ask users to share their location via their mobile devices, forcing them to weigh the cost of sharing this information against the possible benefits. Current platforms for sharing location content (e.g., Google, Facebook) with the range of people in our lives are sorely lacking. Most offer users a single choice: either share your precise geographic coordinates with someone or don't share your location at all. Even applications like Twitter and Instagram only offer limited options for geo-tagging content, typically restricting to nearby places of interest or one's current city. These limited options do not reflect the wide range of personal, professional, and social relationships that exist. One's level of comfort in sharing their location with an acquaintance is very different than with their spouse. Furthermore, processes for sharing typically involve allowing a large commercial company access to your location before it can be transmitted to the intended recipients. To many (especially at-risk individual), the idea of publicly sharing personal location information via one of these limited options is deeply concerning. PrivyTo is a platform that places individuals back in control of their personal location privacy allowing them the freedom to share their location securely and with varying degrees of privacy. Our approach is built on the novel idea of obfuscated and encrypted location views, and promotes a uniquely open method for sharing. A user can share their encrypted location with a variety of individuals (e.g., family, friends, the public). Different keys unlock different views of their location. The public may see my current city, while friends might see my neighbourhood, and my family would have access to my precise geographic coordinates. The entire process is encrypted end-to-end so that no third party application has access to an individual's location. This proposal is to fund entrepreneurial education and market research related to this project idea.
