How DNA from Genetic websites could be used against you

​Fears about the privacy of our data have become commonplace amid credit monitoring hacks and a political firm accessing Facebook users' information.  A recent arrest takes it one step further, raising questions about how our genetic information is being used and who has access to it.  

The arrest was made on the basis of genetic information using an open-source genetic database, GEDmatch, to explore family trees.  Anyone can use GEDMatch, a website for amateur and professional researchers and genealogists. The site's free tools allow people to enter their DNA profiles or genealogical data -- the information received from commercial genetic testing companies such as 23andMe or Ancestry.com -- so they can find familial matches with other users.  In short, the investigators tracked down DeAngelo based on genetic information provided not by him but by one of his relatives.
