Zuus has decided as a company policy to not store any fingerprint images. The only information that Zuus stores is the statistical model required to identify fingers in the future. It is impossible to use these statistical models to reconstruct a fingerprint.
2. How does it work?
So the staff then asks, ‘Well how does it work then?’ Good question.
ZuusTime works with two different biometric fingerprint scanners: the Futronic F88, and the Digital Persona U.are.U4500. These devices scan an image of a fingerprint, and then turn it into a mathematical representation of the fingerprint. This conversion happens on the device, and the fingerprint image is never stored, nor is it transmitted over the network. It is impossible to reconstruct the original fingerprint from the stored data.
At this point, one of two things may happen.
- If this is a registration, then the fingerprint template is linked to the employee.
- Otherwise, the system searches for a matching template. If a match is found, then the rest of the operation is performed, such as a clock out event.
The scanners also have a special electronic circuit built in that prevents attempts to scan “fake” fingers, such as those made from silicone rubber, play-doh or similar.
Tips and tricks for getting the most from your fingerprint scanner
- Best fingers to use are the middle three: thumb is the worst, as the thumbs isoften too large to fit neatly on the scanner area
- Place your finger flat on the glass (not the point),
- Place your finger slowly on the scanner and leave it there until you get a response
- Ask staff to register multiple fingers so they don’t have to remember which finger or fingers they registered.
ZuusTime helps enable this as your staff can register every finger. This also helps when an employee injures their scanned finger and is unable to put it on the scanner.
- If the scanner stops reading it might be that your finger is dry, it helps to oil it up, do this by rubbing the finger in the crease between your thumb and fore finger
3. Why use a biometric fingerprint scanner for your time and attendance solution?
It will prevent buddy pinning.
Buddy pinning is when a staff member is running late or leaves early and asks their friend to clock them in and out. Adding biometric fingerprint recognition into the time and attendance prevents this.
4. What is two-factor authentication?
You may have heard of two-factor authentication (2FA). This has been around since the 1980s, and requires that a person attempting to identify is able to supply two different “tokens” of information, where each token comes from a different group:
- Something you know(in this case, a ZuusTime PIN)
- Something you have, such as a key-fob or RFID card
- Something you are (in this case, a fingerprint)
Using a fingerprint scanner instead of an RFID reader also has some advantages over the “something you have” category. A fob card or similar does not prove that it was the correct employee that clocked in, no more than a plain PIN. Maintaining a group of RFID tokens is also far more work than registering staff using a fingerprint scanner.
For the tech lovers (fellow nerds):
“FS88 was certified by the United States FBI to be compliant with PIV-071006 Image Quality Specification. FS88 meets the US Federal Information Processing Standard 201(FIPS 201) for Personal Identification Verification (PIV) of Federal Employees and Contractors. It is also listed in the US General Services Administration (GSA) FIPS 201 Evaluation Program Approved Product List. FS88 uses advanced CMOS sensor technology and a precise optical system to meet the rigorous requirement on fingerprint image quality of PIV-071006. Its fingerprint scanning window is crown glass with a thickness of 14mm that resists scratches and other stress to ensure long term heavy duty usage. It is a robust but cost effective single finger capture device and ideal for border control, identity card, driver license, election and any type of civilian AFIS application.” cited from http://www.futronic-tech.com/product_fs80.html
