An article about privacy and DNA that I will suggest should be required reading for every genealogist who has submitted or is thinking of submitting DNA information to a publicly-available database is available in the govtech.com web site. It states (in part):

"Vera Eidelman, staff attorney for the ACLU's Speech, Privacy and Technology Project, said people need to think about the wealth of information they're giving up when they use genetic testing kits for fun."

"Genetic testing kits give users a fun look into the past. But what could be at stake in the future is cause for concern among privacy advocates.

"When people think of genetic testing kits, they typically think of companies like 23andMe or Ancestry.com.

"These companies allow you to spit into a tube and mail off your DNA-rich saliva. They report back with information about who your family is, where they're from, famous relatives and, with an upgrade, genetic markers indicating possible diseases you may have inherited.

"This alone concerns organizations like the American Civil Liberties Union.",

The article points out that "Ancestry.com, 23andMe, and My Heritage DNA bar law enforcement from use."
