In the age of open data, privacy and secrecy are hot topics. There is a growing movement towards openness and data sharing in government, as well as in science. Like many scientists, I’m convinced that openness and transparency are largely a good thing, and we astronomers generally take policies of data sharing and posting our work to open access repositories for granted.

An increased call to openness inevitably leads to the question: when should information be secret, and when should it be open? Under what circumstances is it ok, indeed is it recommended, not to share data and information? Or: “When does my right to privacy trump your need for security?”.

The result is an interesting collection of short essays on the topic of secrecy and on the balance between privacy and security, by Lee Smolin, George Dyson and Clay Shirky, amongst others.
