All your identities in one big identity

"Having two identities for yourself is an example of a lack of integrity."

  • Mark Zuckerberg, The Facebook Effect

"If you have something that you don't want anyone to know, maybe you shouldn't be doing it in the first place."

  • Eric Schmidt, interview on CNBC

All your identities in one big identity

“Facebook is a community where people use their real identities. We require everyone to provide their real names, so you always know who you're connecting with. This helps keep our community safe.”

Fuck you, Google

I use my private Gmail account to email my boyfriend and my mother. There’s a BIG drop-off between them and my other “most frequent” contacts. You know who my third most frequent contact is? My abusive ex-husband. Which is why it’s SO EXCITING, Google, that you AUTOMATICALLY allowed all my most frequent contacts access to my Reader, including all the comments I’ve made on Reader items, usually shared with my boyfriend, who I had NO REASON to hide my current location or workplace from, and never did.

All your services in one big service

What's in our privacy toolbox?

  • Cryptography [RSA, AES, Diffie-Hellman]
  • Contextual integrity [Barth et al.]
  • Access control [Bell, LaPadula]
  • Anonymizers [Dingledine, Marlinspike]
  • Blockers [AdBlockPlus, Disconnect.me]

Our tools are necessary but not sufficient.
