Protecting your child's privacy on live streaming video apps

There is a new warning for parents whose children use one of the many popular new video streaming apps.

Your kids may be broadcasting their lives on the internet - essentially bringing strangers into your home.

Not only are they vulnerable, but you may be on camera without even knowing it.

Popular streaming apps like Meerkat, Periscope, YouNowLive have millions of users, especially teens like 16-year-old Katie.

"It's like a modern-day chatroom," she said.

Katie has 22,000 YouNow followers, using the all tp talk to people all over the world in real-time.

"People have made inappropriate comments before," said Katie.

Essentially, every time Katie uses YouNow thousands of strangers can see her and what she's doing.

"It's a little nerve racking that there are people on there that shouldn't be on there," said Katie's mom, Laurie.

Katie's mom is cautious and says she's taking that extra step being her daughter's own personal moderator.

ABC News tried using the app and in a matter of minutes were able to find not only teems but adults doing things that are not exactly PG-13.

Cybersecurity expert Theresa Payton then shows us how the live steaming app Periscope works.

In a matter of seconds, we are broadcasting life and people immediately start commenting.

Experts say apps like these can expose kids to inappropriate videos, subject them to real-time bullying and even put your child's safety at risk.

To show how quickly someone cal find your location while using one of these live streams, we use our producer's Periscope account.

After watching a recent live strean, we're able to see her username which is linked to her Twitter account.

Once we have her general location and handle, we plug that information into this free website and every time she posts something on social media, her exact location pops up.

It's like leaving a trail of breadcrumbs.

"And you can tell if they are stale or fresh because they have time stamps," said Payton.

Meerkat said in a statement to ABC news: "We are constantly evaluating the best privacy, trust and safety systems to serve our community."

Periscope points to their guidelines that urge users to not show graphic material content.

YouNow says broadcasters are monitored 24/7 and any user who is reported not to have yet their standards is quickly disciplined.

All 3 apps encourage you to report inappropriate behavior and to block anyone being offensive.
