Monetize Me? Privacy and the Quantified Self in the Digital Economy

生活记录和自我量化曾经是运动员、有特定医疗条件的人，以及那些有时间、金钱和动机使用昂贵的专业设备来监控自己的人的小众领域。现在，普通人跟踪和分析他们生活的许多方面的技术变得既便宜又不可见，几乎不需要花费精力或费用来收集。有许多商业模式是基于挖掘人们在线活动的所谓“数字废气”来提供看似免费的服务。事实上，越来越多的人现在能够自动记录他们生活的方方面面（除了他们访问过的网页），这为新的商业模式创造了机会，为生成数据的人提供服务。例如，有些人可能希望出售他们的数据以换取现金，而不是将其赠送出去，有些人可能希望将其捐赠给有价值的科学事业，例如卫生研究，而另一些人可能希望仅以非识别汇总形式共享数据，或者根本不共享数据。生活记录数据的范围可以从相对温和的（比如一天中键入的键盘次数）到非常私人的（比如情绪唤醒状态），并且数据共享的方式可能非常微妙。该项目旨在了解不同人口群体的隐私和共享需求是如何变化的，并建立专门为生活记录数据设计的共享和隐私基础设施。

Lifelogging and self-quantifying used to be niche areas for athletes, people with certain medical conditions, and those with the time, money, and motivation to use expensive specialist equipment to monitor themselves. Now the technology for ordinary people to track and analyze many aspects of their lives is becoming both affordable and invisible, requiring little effort or expense to collect. There are many business models based on mining the so-called 'digital exhaust' of people's online activity to provide apparently free services. The fact that so many more people are now able to automatically log so many aspects of their lives (beyond which web pages they visited) is creating opportunities for new business models to actually provide services for the people generating the data. For example, some people may wish to sell their data for cash rather than give it away, some may wish to donate it to worthy scientific causes, such as health research, while others may wish to share data only in a non-identifying aggregated form or perhaps not at all. Lifelogging data can range from relatively benign (such as number of keystrokes typed in a day) to the highly personal (such as the emotional arousal state) and the ways in which the data is shared may be highly nuanced. This project seeks to understand how the privacy and sharing requirements vary across different demographic groups and to build a sharing and privacy infrastructure specifically designed for lifelogging data.
