The latest in security

Progress has meant we have upgraded much of our technology and systems to be able to do jobs more efficiently. Of course, part of this has meant those who want to steal from us have found efficient ways to do so. It’s important then to know just what is happening in the security world to help stay one step ahead of those who would commit crimes against us. This is especially true for us as homeowners.

Consider, for example, the use of fingerprint technology to access logins for specific users. It seems perfect: you have your hands on you and, instead of entering a password to identify it’s you, you just put your hand on the device. This has been particularly prominent in recent cellphones, especially iPhones. But, as TechTimes points out, this has been a system that many have duped.

“Newer iPhone models feature a fingerprint sensor for security — and a high-quality camera capable of taking a photo that can fool that fingerprint sensor.”

But knowing of this, security experts have attempted to counter it.

‘The new fingerprint sensor, described in the journal Applied Physics Letters, contains a tiny ultrasound imager. This allows the sensor not only to capture more details about the distinctive designs on the surface of your fingertips, but also to collect information about tissues below the surface.

‘”Existing smartphones use capacitive fingerprint sensors that measure a 2D image of the finger surface,” said senior study author David Horsley of the University of California, Davis to Tech Times. “The ultrasound image may allow discriminating between a live finger and a printed fingerprint — a vulnerability of capacitive sensors.”’

Many people know “ultrasound” but aren’t quite aware what that means. In this instance, ultrasound imaging works by bouncing ultrasound pixels off certain body parts — here, it’s the tip of a finger. These pixels then get reflected back to a sensor, and this allows it to construct an accurate 3D image – this image is not only the surface of the skin, but the tissue beneath it.

All of this rings true for what we decide to monitor in central places like a security control room. Considering cameras can achieve that for phones, we have to note what cameras designed for security can achieve. As CNET notes, you need all sorts of functions for cameras to have the perfect set of features: Motion-sensors, light activated, sharpness, clarity, storage and many others are essential to creating a system of security that is reliable and efficient.

Cameras are only one part of the system, of course, but we need every part up to scratch in order for the whole system to be regarded as functional. Though most homes won’t use such sophisticated tech, it is important to be aware of how technology is progressing in security.
