I'm not so sure this is true.
This came up in a discussion with Jishnu yesterday, and we needed a common starting place. So I'd like to take a little time to lay out what I'm thinking when I talk about Privacy, especially since I'm mainly focused on empowering individuals with control over data sharing and not so much on keeping secrets.
Privacy is the ability for an individual to have transparency, choice, and control over information about themselves.
First, an organization's (or individual's) collection, sharing and use of data must be transparent. This is crucial because choice and control cannot be realized without honesty and fairness.
Second, individuals must be provided choice. This means data subjects (those people whose data is being collected, used or shared) must be able to understand what's going to happen with their data and have the ability to provide dissent or consent.
Third, when it's clear what's happening and individuals have an understanding about what they want, they must be given control over collection, sharing or use of the data in question.
This means control depends on choice which depends on transparency. You cannot make decisions unless you're given the facts. You cannot make your desires reality unless you've decided what you want.
For the engineers out there (like me), this dependencies can be modeled as such:
[Transparency] = Awareness of Data PracticesControl is the goal, but it requires Transparency and Choice to work -- as well as some additional inputs. Privacy is the whole thing: all three pieces acting together with support from both data controllers and data subjects to empower individuals with a say in how their data is used.
[Choice] = [Transparency] + Individual's Wants
[Control] = [Choice] + Organizational Cooperation
The privacy perception gap is a symptom of ineffective transparency and choice; it is the result of peoples' inability to really understand what's going on so they have no chance to establish positions about what is okay. When transparency and choice are built into a system, the gap shrinks and people have most of what they need to regain control over their privacy.
What is privacy to you?
