Did you know? The photos we take have the risk of leaking our personal information. Apparently, photos that show fingerprints have this risk.
But can fingerprints be easily copied? Let's find the answer together with NIMASO!!
Copying a fingerprint is not easy, but it's not impossible either.
In the film Ant-Man, the screenwriters used a 30-minute quick cut to show the audience how to get fingerprints using tools in a kitchen and then use them to unlock a fingerprint lock.
When I first saw this scene, I laughed, "This is the 21st century, and this is kindergarten level?" However, the NIMASO staff who accompanied me said, "Similar scenes appear in many action and science fiction movies, and the director probably wants to show the wisdom of the main character."
I have researched it. The veteran program "Mythbusters" of the American Discovery Channel also made a program about it. The results of the program show that optical fingerprint recognition is possible as long as the fingerprint image is clear enough. However, the program was made in 2006. At that time, optical fingerprint recognition technology was the mainstream technology in the encryption industry, so a photo with visible fingerprints could be used intentionally.
In 2017, researchers at the National Institute of Informatics (NII) succeeded in extracting a usable fingerprint from a photo taken three meters away. Today's mobile phone cameras are often tens of millions of pixels, and the photos they take are much clearer than those taken at that height. And it was apparently not difficult to collect a clear fingerprint from a photo.
There are risks, but they may not be something to worry about too much.
There is a difference between leaking fingerprint information and jeopardizing the security of our property.
The fingerprint authentication system used by the iPhone is capacitive fingerprint, which has an additional threshold to identify bioelectric information, making it difficult for criminals to create conductive simulated fingerprints, and the safety factor is relatively high.
Some devices also have a live detection feature that uses auxiliary information such as body temperature and heart rate to determine if a scanned fingerprint belongs to a real person, adding an extra lock to your phone information.
In summary, if you have a phone with optical recognition under the screen, it may be cracked by fingerprint information leaked through photo scissors.
However, smartphone manufacturers have also added a last line of defense for users: entered fingerprint information is only stored locally and not uploaded to the network, making it impossible for hackers to launch a large-scale intrusion campaign.
This means that if someone wants to hack into your phone, he would need to get both your fingerprint information and your phone.
So, if your fingerprints are visible when you take a photo, it may leak your information security, so be aware of it.
Also, when you enter a password on your smartphone, please be aware of the eyes of those around you. NIMASO recommends that you apply a privacy glass film. In addition to being conscious of protecting our personal information, we should also be conscious of our health.
NIMASO would like to introduce a new friend to your new life starting this spring: the NIMASO antibacterial glass film series . NIMASO applies a hybrid antibacterial coating during ion exchange, which not only maintains a permanent antibacterial function, but also effectively inhibits the growth of bacteria with a 99.9% antibacterial rate (antibacterial rate for Escherichia coli and Staphylococcus aureus according to the SGS inspection report).
In addition, NIMASO has developed a glossy, antibacterial glass film that utilizes high-transmittance technology to improve the display quality of the iPhone 13 series. NIMASO has also added antibacterial properties to its blue light blocking glass film, reducing the strain on the eyes while also providing antibacterial effects. Say goodbye to germs with NIMASO this spring!
Finally, NIMASO has some suggestions for photography during Golden Week.
With Golden Week coming up soon, if you are able to enjoy the remnants of spring and the early summer scenery of sunlight filtering through the trees and hydrangeas, please take photos of the beautiful scenery, interesting things, cute animals, etc. that you see and share them with NIMASO. Travel with NIMASO and get a JTB travel voucher worth up to 20,000 yen!! This event starts on April 28th!!
