ABSTRACT
This article explores the gap between privacy and design in the context of “lateral privacy”—
privacy issues arising among users of a service rather than from the service provider—on social
networking sites (SNSs) and other platforms by analyzing the privacy concerns lodged against the
introduction of Facebook’s News Feed in 2006. Our analysis reveals that the dominant theory of
privacy put forth by regulators, privacy as individual control, offers little insight into the
experiences of privacy violation claimed by users. More importantly, we show that this theory is illequipped to guide the design of SNSs and platforms to avoid similar harms in the future. A rising
tide of privacy blunders on social networking sites and platforms drives the search for new
regulatory approaches, and privacy regulators across the globe are increasingly demanding that the
Fair Information Practice Principles, the embodiment of privacy as individual control, inform the
design of technical systems through Privacy By Design. The call for Privacy By Design—the
practice of embedding privacy protections into products and services at the design phase, rather
than after the fact—connects to growing policymaker recognition of the power of technology to not
only implement, but also to settle policy through architecture, configuration, interfaces, and
default settings. We argue that regulators would do well to ensure that the concept of privacy they
direct companies to embed affords the desirable forms of protection for privacy.
Ideally, there would be a widely used set of methods and tools to aid in translating privacy into
design. Today, neither is true. We identify three gaps in the “informational self-determination”
approach that limit its responsiveness to lateral privacy design decisions in SNSs and platforms
and then explore three alternative theories of privacy that provide compelling explanations of the
privacy harms exemplified in platform environments. Based on this descriptive utility, we argue
that these theories provide more robust grounding for efforts by SNSs and platform developers to
address lateral privacy concerns in the design of technical artifacts. Unlike FIPPs, which can be
applied across contexts, these theories require privacy to be discovered, not just implemented. To
bridge this discovery gap, we turn to the field of Human Computer Interaction (“HCI”) and dip
into the related field of Value Sensitive Design (“VSD”) to identify tools and methodologies that
would aid designers in discovering and ultimately embedding these contextual, socially- oriented

the form and substance of regulations that would prompt corporations to invest in these HCI
approaches to privacy.

While the U.S. has continued to take a largely sectoral approach to privacy, it has enacted
statutes to advance FIPPs. See, e.g., Right to Financial Privacy Act (“RFPA”), 12 U.S.C.
§§ 3401–22 (2006) (protecting the confidentiality of personal financial records by creating a statutory Fourth Amendment protection for bank records); Gramm-Leach-Bliley Act
(“GLBA”), 15 U.S.C. §§ 6801, 6827 (2006) (empowering various agencies to promulgate
data security regulations for financial institutions); Electronic Communications Privacy
Act of 1986 (“ECPA”), 18 U.S.C. §§ 2510, 2511 (2006) (extending restrictions against

identifiable rental records of “prerecorded video cassette tapes or similar audio visual material”); Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), Pub. L.
No. 104–91, 110 Stat. 1936 (1996) (codified as amended in scattered sections of 42
U.S.C.) (regulating the use and disclosure of “Protected Health Information” in the section 1173 under “Security Standards for Health Information” Section 2).
