APIs and Your Privacy

Application programming interfaces, or APIs, have been the topic of much recent discussion. Newsworthy events, including those involving Facebook’s API and Cambridge Analytica obtaining information about millions of Facebook users, have highlighted the technical capabilities of APIs for prominent websites and mobile applications. At the same time, media coverage of ways that APIs have been misused has sparked concern for potential privacy invasions and other issues of public policy. This paper seeks to educate consumers on how APIs work and how they are used within popular websites and mobile apps to gather, share, and utilize data. APIs are used in mobile games, search engines, social media platforms, news and shopping websites, video and music streaming services, dating apps, and mobile payment systems. If a third-party company, like an app developer or advertiser, would like to gain access to your information through a website you visit or a mobile app or online service you use, what data might they obtain about you through APIs and how? This report analyzes 11 prominent online services to observe general trends and provide you an overview of the role APIs play in collecting and distributing information about consumers. For example, how might your data be gathered and shared when using your Facebook account login to sign up for Venmo or to access the Tinder dating app? How might advertisers use Pandora’s API when you are streaming music? After explaining what APIs are and how they work, this report categorizes and characterizes different kinds of APIs that companies offer to web and app developers. Services may offer content-focused APIs, feature APIs, unofficial APIs, and analytics APIs that developers of other apps and websites may access and use in different ways. Likewise, advertisers can use APIs to target a desired subset of a service’s users and possibly extract user data. This report explains how websites and apps can create user profiles based on your online behavior and generate revenue from advertiser-access to their APIs. The report concludes with observations on how various companies and platforms connecting through APIs may be able to learn information about you and aggregate it with your personal data from other sources when you are browsing the internet or using different apps on your smartphone or tablet. While the paper does not make policy recommendations, it demonstrates the importance of approaching consumer privacy from a broad perspective that includes first parties and third parties, and that considers the integral role of APIs in today’s online ecosystem

The Economics of Internet Markets

The internet has facilitated the creation of new markets characterized by large scale, increased customization, rapid innovation and the collection and use of detailed consumer and market data. I describe these changes and some of the economic theory that has been useful for thinking about online advertising markets, retail and business-to-business e-commerce, internet job matching and financial exchanges, and other internet platforms. I also discuss the empirical evidence on competition and consumer behavior in internet markets and some directions for future research.internet, market, innovation, advertising, retail, e-commerce, financial exchanges

Monetizing Personal Data: A Two-Sided Market Approach

© 2016 The Authors. Mobile phone-based sensing is a new paradigm that aims at using smartpohnes to answer sensing requests and collect useful data. Nowadays, a wide variety of domains ranging from health-care applications to pollution monitoring are benefiting from such collected data. However, despite its increasing popularity and the huge amount of data provided by users, there is no platform where mobile phone owners can effectively sell their data. In this paper, we propose the idea of a data monetization platform using two-sided market theory. In this platform, the data is viewed as an economic good and the data sharing activity is considered as an economic transaction. The proposed platform considers the case of abundant data. An experimental analysis is conducted to compare our approach against the peer-to-peer model using a real case study from the health care domain. We show that our proposed platform has the potential to generate higher profit for both data providers and data consumers

Monetized Gameplay: Analyzing Commodification in Rainbow Six Siege

Game studies scholars have had growing concerns over the last decade about monetization strategies in video games. This major research paper expands on this conversation by analyzing monetization in the case of Ubisoft’s Rainbow Six. The paper explores different commodification strategies such as platformization, assetization, gamblification, and data extraction as well as monetization devices such as the battle pass and loot box. By applying elements of the app-walkthrough method to Rainbow Six Siege, this project concludes that previous efforts to regulate monetization in video games ought to recognize monetization systems’ deep integration with gameplay. Monetization strategies, I argue, overlap with and shape gameplay. Moreover, rather than approach them as separate, I suggest that monetization and gameplay are mutually constituted. The paper draws on game news sources to support the analysis of monetization systems. Ultimately, this MRP reveals: 1) that gamblification is not a discrete practice that only exists in the Rainbow Six Siege’s menus, but is embedded throughout the game; 2) that keeping the player engaged allows for data capital to keep being extracted; and 3) that Rainbow Six Siege places the onus of responsibility on the player and makes monetization seem as if it is a gift

Understanding Privacy Disclosure in the Online Market for Lemons: Insights and Requirements for Platform Providers

Future used car markets may use personal data to reduce information asymmetries between car sellers and buyers, e. g. on past driving behavior. Reducing information asymmetries is attractive for used car platforms as they can move from pure information provision to orchestrating transactions. However, car sellers and buyers have to agree to sharing personal data. What kind of data is interesting for them? Under what circumstances are they willing to share this data? What should a platform do to support data sharing? We explore those research questions as part of the Cardossier project by conducting experiments with the Car-Market Game, simulating a future car market. The results indicate that there is no market for pure personal data (e. g. photographs of sellers), but there is a market for car usage data. From future used car platforms the participants expect disclosure control and disclosure transparency in an environment free of interpersonal trust
