This might be a new innovation that aims at ensuring the security of your digital devices. I am however skeptical about a few things. What happens when you injure your fingers? Safety is another issue. The sensor transforms the image from the fingers into encrypted data that can still be hacked by experienced hackers.

Nice to see I'm not the only skeptic, Al, but I didn't even think about the possibility of identity theft through fingerprints but you never know what hackers will come up with next! definitely could happen.

But what about going around the sensor?

W@hile fingerprint recognition hardware may be quite able to record a really high definition image of a fingerprint, , it then gest converted into a string of digital data, at which point it is probably much easier to compromise. Just like those unpickable locks that can be broken fairly easily, not every methode is secure from end-to-end, and it looks to me like the fingerprint system could be hacked a bit farther downstream. So uniqueness is not the only concern here.

The biggest problem is that damage to your fingertips would lock you out of the system. I'm talking a cut or a burn. I solder small parts and am forever burning slots and holes in my fingertips, and my coffee machine (yep it has a fingerprint sensor) didn't recognise me. Luckily it has a bypass button, but that wouldn't be an option for secure access to something.

I'm with you on that for the same reasons, and given that mythbusters actually circumvented a fingerprint system buy photocopying a fingerprint they pulled of a surface I think only high resolution capacitive sensors offer any real level of security.

They say that fingerprints are more secure than passwords, but I beg to differ on that. While they are almost unique (seriously only almost) unless the verification system also verifies that the fingerprint is on a real hand of a living person a well chosen non-shared password will be more secure.

In case you're wondering why I said "almost" earlier, New Scientist published an article on forensics a while back where they stated roughly how many people in the world (statistically) share the same fingerprints and it wasn't one :-). Of course the likelyhood of 2 people with the same fingerprints crossing paths is much less again.

It's because of the resolution of existing touch screen, they can see less that 20 variations across the whole screen

Not being bug-free would especially be a problem for this technology. Nothing like security technology that doesn't work properly.  Does this also open the door to stealing identities via fingerprint scans?  Not sure about if that is an issue.

Really, Cabe? That's interesting...so you're right! This had better be good and ready for primetime and as bug free as possible.

True, shehan, these things usually prove themselves fairly quickly. I myself am a cautious early adopter--I think usually by version 2 or 3, products really hit their stride. The only exception I made was the iPhone, but I still think the later versions were better!

@Shehan: True but there will be issues and limitations too involved in this.

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
Fifteen European research centers have launched EuroCPS to help European companies develop innovative products for the Internet of Things.
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
Biomedical engineering is one of the fastest growing engineering fields; from medical devices and pharmaceuticals to more cutting-edge areas like tissue, genetic, and neural engineering, US biomedical engineers (BMEs) boast salaries nearly double the annual mean wage and have faster than average job growth.
