A San Diego man has apparently found his long-lost half-brother through Facebook's facial recognition technology -- a technology that has come under fire from privacy groups.
According to a report in the Daily Mail, Charles Carte has spent years trying to find his half-brother, whom his dad fathered while stationed in the Philippines during the Vietnam War.
The search proved fruitless, but they got lucky when Carte's sister posted old pictures of their father on Facebook.
Facebook's software then took over -- scanning the father's face, and then making a friend suggestion to the sister -- a man who had also posted a photo of a man resembling their father.

"My sister out of the blue called me up and said, 'Wow, I think we may have found our half-brother,'" Carte told 10News in San Diego.
"When that happened, I immediately sent him a friend request and also called my father and let him know that I think we may have found his son whom he hasn't seen in 45 years," Carte said.
Carte said these are the photos that led to finding his half-brother:
"It had to be this," he said. "There's no other way around it. We didn't have any mutual friends."
