How Hackers Can Recognise The PIN Numbers From ATM!!!!

   In Washington, Beware! Modern-day hackers can recognize your PIN numbers from ATM keypads using a digital infrared camera.

   At the USENIX Workshop on Offensive Technologies earlier this month, researchers from the University of California at San Diego (UCSD) have described how a digital infrared camera could be used to reveal digits of PIN numbers after a user punched them in on ATM keypads.

   Researchers showed that the residual heat our fingertips left behind on the ATM keypad can be detected by the digital infrared cameras, easily revealing the digits of your PIN.

   When the camera was used immediately after the transaction, researchers correctly identified the numbers with over 80 per cent accuracy.

   Even after a minute, researchers were able to correctly identify digits about 50 percent of the time.

   Plastic and rubber keypads were most prone to retaining fingertip heat. Even so, they still had their flaws.

   "With plastic keypads, we can reliably detect which buttons were pressed, but it is really difficult to determine the order," Discovery News quoted Keaton Mowery, a doctoral student in computer science at UCSD, as telling Technology Review.

   Mowery conducted his research with fellow student Sarah Meiklejohn and professor Stefan Savage.

   This is unbelievable, some news makes happy because the order to determine PIN code is very difficult but when it also comes to know it’s very dangerous to our money. They should take some action to prevent our money.

Nano-Sized Engineering!!!!!

    Scientists have developed a new microscope which can penetrate deep within materials and see details as small as a billionth of a meter without even using a lens.

   This new microscope was developed by physicists at University of California, San Diego by using a powerful computer programme to convert patterns from X-rays bouncing off materials into imager of objects as small as a one nanometre across, on the scale of a few atoms.

   Here's a example of superman's X-ray vision which allows him to look through walls to see the bad guys beyond, similarly, the nano vision is used to look at the different elements inside a material or to image viruses, cells and tissue in great detail.

   It has one of the most important applications that is, in nano-sized engineering.

   Astronomers use similar programmes to remove distortions from their images and even to sharpen the pictures sent back by the Hubble telescope, but the nano-vision technique is new.

   Researchers, to test the programme created a layered film made of the elements iron and gadolinium. Combined, the two magnetic materials crinkle into a series of magnetic domains that look like a maze or the ridges of fingerprints.

   Shpyrko mentioned by seeing and understanding how the materials self-assemble, you could create nano-production processes that are much more efficient than the current method of building materials atom-by-atom, Shpyrko said.

   Shpyrko also mentioned that by understanding magnetic materials at the nanoscale could lead to better magnetic data storage.

   X-ray nano-vision also helps to see inside the interface to diagnose the problem between the battery's electrodes and electrolyte degenerates when batteries degrade overtime. This helps to know how this happens or how to fix it inside the interface and solve the problem.

  Shpyrko made a statement that “With this microscope, we can actually look at this very difficult interface.”

  Thanks, making to forget of X-ray glasses by developing, X-ray nano-vision which helps to see tough interface. Great!!!!!
