An independent computer security researcher uncovered a database of information on 191 million voters that is exposed on the open Internet due to an incorrectly configured database, he said on Monday.

The database includes names, addresses, birth dates, party affiliations, phone numbers and emails of voters in all 50 U.S. states and Washington, researcher Chris Vickery said in a phone interview.

Vickery, a tech support specialist from Austin, Texas, said he found the data while looking for information exposed on the Web in a bid to raise awareness of data leaks.
