LAS VEGAS -- The controversial body scanners at the airport could soon get some major updates that will better protect your privacy. The software is being tested out at McCarran International Airport.

They scanners have enhanced security at airports across the country, but are not always welcomed with open arms. Privacy has been a huge concern for some travelers, many not comfortable with their detailed body image being taken.

"That's kind of like invading privacy. It was kind of too much information," said passenger Oscar Vidal.

Now new software being tested at McCarran could put privacy issues to rest. The new software makes the whole body scanning process a lot less intrusive. Once a passenger walks through this scanner, an image pops up on the monitor of a generic body, only showing potential trouble areas.

"The image is the same for everyone, so it wouldn't be intrusive at all. People would be able to walk through, look at the image and it doesn't look like them, it looks like everyone else," said Dwayne Baird with the TSA.

If a yellow patch shows up on your body scan, you are taken for a secondary screening of that specific area. The process is called targeted pat downs.

Because the body images are so generic, TSA agents will also be able to monitor the scans right next to the machines as opposed to a remote area.

"The image is then immediately cleared and the next person comes into the machine for the next scan," said Baird. "There's no ability for this machine to save or retain the image whatsoever."

Some passengers think the new software is a positive change.

"It will probably help, because that is their main issue -- showing all of the lines and everything. I think it will help," said Vidal.

Enhanced pat downs will still be used if needed. The TSA says the software is being tested out at three airports in the United States. After several months of review, they will decide if machines nationwide will get the upgrade.
