Tensions in our Information Society reduce trust

1. Culture: Normalization of radical transparency vs trust gap

2. User experience: Increased individual control of personal data vs. opaque use

3. Political process: Major sector of economy/society poorly understood

‘What they Know”

Trust Challenge

Judge Reggie B. Walton, Chief Judge, Foreign Intelligence Surveillance Court

“the court lacks the tools to independently verify how often the government’s surveillance breaks the court’s rules that aim to protect Americans’ privacy”• Washington Post, August 15,

2013

1. Transparency without trust

Growing Individual Control

• Personal health data tied to individual

• How will this shape privacy expectations?

2. Control vs opacity

New Privacy Priorities: Prevent Discrimination and Sustain Trust

Discrimination: “The increasing use of algorithms to make eligibility decisions must be carefully monitored for potential discriminatory outcomes for disadvantaged groups, even absent discriminatory intent.“

11

Importance of Accountable Systems

“Although the state of the art is still somewhat ad hoc, and auditing is often not automated, so‐called accountable systems are beginning to be deployed.

The ability to detect violations of privacy policies, particularly if the auditing is automated and continuous, can be used both to deter privacy violations and to ensure that violators are punished. (pp. 42-43)

Stop Online Piracy Act: Engineer’s View

• “If enacted, either of these bills will create an environment of tremendous fear and uncertainty for technological innovation, and seriously harm the credibility of the United States in its role as a steward of key Internet infrastructure. Regardless of recent amendments to SOPA, both bills will risk fragmenting the Internet's global domain name system (DNS) and have other capricious technical consequences. In exchange for this, such legislation would engender censorship that will simultaneously be circumvented by deliberate infringers while hampering innocent parties' right and ability to communicate and express themselves online.”• https://www.eff.org/deeplinks/2011/12/internet-inventors-warn-
