This drop in accessible data has caused law enforcement agencies to start campaigns to persuade the public to opt-in and share their DNA profiles from consumer websites with law enforcement for investigative purposes. Rightfully, many members of the public are reluctant to share this information for fear that their DNA profiles will be used for other purposes or sold to marketing or health care companies. Nevertheless, law enforcement continues to urge the public to allow access to these data for the greater good. So far, about 180,000 users have opted-in. But before you choose to release your DNA profile, be sure to do your due diligence and learn more about what it might mean for the future privacy and security of data.
