Biometric System

“We require parents to read through the information regarding the Biometrics System that will become live in the schools canteens shortly. Please can you either complete the slip on the bottom of the Biometrics Information Letter and return it to school or email with your childs full name and form and state if you are happy for them to use the Biometric System. Thank you!”

What are Biometrics?

Biometrics authentication is the automatic recognition of a living being using suitable body characteristics. By measuring an individual’s physical features in an authentication inquiry and comparing this data with stored biometric reference data, the identity of a specific user is determined. There are many different biometric features that can be used for authentication purposes these include finger image, signature, iris, retina, DNA or any other unique characteristic. Once a characteristic has been chosen the next stage in the Biometric process is authentication. A biometric feature is saved on to a database. Once the data has been stored, a new scanning of the biometric feature is taken. If the comparison is positive, access to the appropriate application is granted.

Biometrics and Security

Students, parents and staff can rest assured that the fingerprint images cannot be used by any other source for identification purposes. The system uses an image of the finger to create a mathematical algorithm and then discards the finger image; only the numbers remain and these cannot be reinterpreted back into a finger image.


Why do you need to take my child’s finger image?
By taking an image of your child’s finger we can turn this information into a digital signature.

Can finger images be used by any other agency?
No, the software we use turns your child’s finger image in to a mathematical algorithm. The image of the finger is then discarded. The information that is stored cannot be used to recreate an image of the child’s finger.

What happens when my child leaves the School?
When a student leaves school all data can be deleted very easily.

How does it work?
When the child places his/her finger on the scanner, the software matches their finger image with the unique digital signature held in the database.
