A recent poll found that when it comes to their personal info, more Americans trust the National Security Agency or the Internal Revenue Service over Google or Facebook. That's why Mozilla's VP of business and legal affairs, Denelle Dixon-Thayer, says "data hygiene" should be something every new or established tech company should be concerned about. "Trust is our currency," Thayer says in this interview. "If we don't have the trust of our users then we actually aren't going to be successful as a company." Dixon-Thayer says big data companies need to be upfront with users about who has access to their data, how long their data is stored, and do what they can to inform users of government data requests.
