Two hackers managed to trick a vein scanning system just by using a simple wax hand.
As the name suggests, vein authentication systems use a computer to scan and verify a user's veins by studying their shape, size and position underneath a hand.
But it seems the system isn't totally foolproof, as security researchers Jan Krissler and Julian Albrecht revealed the sensors could be duped by creating a fake hand out of wax.

Security researchers Jan Krissler and Julian Albrecht discovered a vein authentication system could be fooled. They created a pair of fake wax hands (pictured) that tricked its sensors
Krissler and Albrect unveiled their research at Germany's Chaos Communications Congress earlier this month.
Using the wax hand, the pair were able to bypass scanners manufactured by Hitachi and Fujitsu, which they say make up 95 percent of the systems used in the vein authentication market, according to the Verge.
They copied another person's vein patterns by taking a photograph with a SLR camera that had its infrared filter removed.
By disabling the infrared filter, they were able to see the person's vein layout.
This allowed them to build a wax model of the person's hands that included their veins.
'It's enough to take photos from a distance of five meters, and it might work to go to a press conference and take photos of them,' Krissler told Motherboard.
'...When we first spoofed the system, I was quite surprised that it was so easy,' he added.

That said, it did take 2,500 photos of a single hand in order for the researchers to get a copy that would enable them to replicate the vein patterns, meaning it takes some pretty significant trial and error to get it right.
After taking the photograph, Krissler said they printed the vein patterns using a laser printer and then covered the print with beeswax to simulate human tissue.
In all the process, took about 15 minutes or so.
From there, they were able to fool the vein authentication systems using the hand.
Krissler and Albrecht contacted Fujitsu and Hitachi to notify them of their findings, but only Hitachi agreed to a presentation of their research, Motherboard noted.
Link hienalouca.com Interesting to note Looking for an investor or sponsor for a project to grow dinosaurs and relict plants. Requires the sum of investments from 400000$ to 900000$. The exact amount can not say because there are many nuances. It will be necessary to build a small laboratory with certain parameters. To all interested persons please write on an email angocman@gmail.com . It is the scientific project and I do not know whether it is possible to earn on it. The probability of success of the project is approximately 60%. That will be very interesting.https://hienalouca.com/2019/01/01/the-wax-hand-that-let-hackers-trick-vein-authentication-security-scanners/

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.
Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
