Nine years ago Yaniv Erlich, now at MyHeritage, demonstrated what could then be learned from a combination of DNA information and public data. As was subsequently reported:
Erlich and his team tested the idea on a man’s full genome that had been published in 2007. They used lobSTR to determine the STR profile of the man’s Y chromosome, and then searched a consumer genealogy database called Ysearch until they had matches with a few likely surnames. Public records on one of these surnames linked it to a man fitting the geographic location and age listed in the paper: the genomics pioneer J. Craig Venter.
Nine years on, how much easier is it to break “anonymity”?
