With today’s technological innovation, almost anything is accessible over the Internet, and gadgets are so advanced that different features are offered.

The technology today may be making our lives better and more efficient, but this is also the reason why many of us are getting scammed, or worse, victims of online threats.

Every one loves taking selfies with their superb smartphone camera technology. And most of us, when we take a selfie or just a plain picture, we often make a V-sign for the camera.

A v-sign on a picture usually means a peace sign or an okay or victory sign for most countries. When we take “wacky” pictures, these v-signs are often seen.

But according to Hong-Kong based news website Inkstone, this v-sign may lead to fingerprint theft. Cybersecurity experts have warned the public especially the online users to stop or refrain from making a v-sign on a picture and posting it on different social networking sites.

Shanghai Information Security Trade Association director Zhang Wei explained that experts or hackers could make fingerprints models off the photos with a v-sign held close enough to the camera.

Smartphone cameras today are so advanced that photo magnifying and artificial intelligence-enhanced technologies make it possible to extract enough detail on the fingers to make a perfect copy of the fingerprint.

According to Zhang, it is advisable to make a v-sign on a photo if it will be taken 10 feet away from the camera. He added that if a v-sign is photographed within 5 feet, fingerprints by then can be clearly extracted and copied.

These extracted fingerprints can then be used to access smartphone recognition, especially now that many smartphone users adopt the fingerprint recognition to lock and unlock their phones.

Well, forewarned is forearmed!
