The ever-present concerns for privacy are further heightened by the growing diffusion of big data. Nearly everyone among us has its personal data stored in some (most probably many) databases around the world, with virtually no control over them. The (lack of) actual privacy guarantees is the subject of a recent paper by Heffetz and Ligett
Heffetz, Ori, and Katrina Ligett. 2014. "Privacy and Data-Based Research." Journal of Economic Perspectives, 28(2): 75-98.
The paper is very interesting. It does not deliver new results, but rather provides a clear description of differential privacy, its criticalities, and the treatment of privacy issues for researchers.
After reading the paper, I've drafted a visual summary. It's not the best of sketch notes I've seen, but I hope you find it useful.
