Nowadays people like to share their fun selfies on social media. But there is bad side which can be dangerous for your security.
It turns out that some popular photo poses, like making a peace sign with your hands, can reveal personal information. Later on, this information can be used against us by scammers.
In this case let’s discuss about why Rocking a Peace Sign in Your Images Can Put You in Danger.
Photos of our fingers can expose us
Japan’s National Institute of Informatics (NII) recently did some research by testing photos of a subject taken by a digital camera from about 9 feet (3 meters) away.
The researchers found that it’s possible to copy the subject’s finger vein patterns from it. Thanks to advanced fingerprint recognition technology, the appendages can be scanned, copied, and then used.
When better the picture’s quality, it can be more dangerous.
Today all of us smartphones keep getting better and boast advanced cameras that are able to take high-resolution pictures.
The danger situation comes when photos taken with them get posted online. This raises the risk of personal information being leaked.
According to researchers, good focus and good light in a picture are enough to recreate data from fingerprints.
Our stolen data can then be used against us.
When someone stolen your personal information, it can be sold online on some black market websites, for example. Nowadays most people use their fingerprints to open various apps and devices where we can easily manage our financial activities.
Once scammers receive access to your personal information, they can use it to get into your bank account and other personal accounts.
It’s not hard to imitate one’s fingerprints.
Not only these things, but also fingerprints can pose is the creation of a printed replica that can fool biometric scanners by using conductive ink.
According to the researchers at Michigan State University have proven that there’s no need for any special equipment to make this recreation. An inkjet printer, conductive ink, and regular paper were enough to fool a fingerprint scanner.
How To protect yourself
A researcher from Japan’s National Institute of Informatics went further into the investigation and developed a clear sticker that had a fake finger vein pattern imprinted on it.
It’s supposed to help to prevent hackers from taking the real data from your fingers when you show them in photos or use them on different devices.
To be on the safe side, you can try to secure yourself by simply changing the pose of your fingers when you take a picture.
Apart from this, you can also improve your security by not using fingerprint authentication on your phone to unlock it or get access to important apps.
