Researcher Jeremiah Fowler found a cloud database containing more than 9 million image files accessible without authentication, WIRED reports.

The leaky bucket, containing some 450 GB of images, was traced back to a US-registered company called ClarityCheck.

In their own words, ClarityCheck says:

“Use reverse image search to identify anyone in a photo. Find names, social profiles, and online presence in seconds.”

While ClarityCheck says it does not use facial recognition, it does describe its image function as a way to identify people and find their names and social profiles.
