Cashless Catering works with the latest biometric recognition technology. A thumb print scan will create a unique algorithm which can be used at the cash top up machines and at the tills in the school canteen.
What is a biometric algorithm?
The individual templates are encrypted using a 256 bit AES key that is built into the scanners hardware. Also the persisted file is encrypted using a different 256 bit AES key built into the matching algorithm supplied by Secugen and generated by a unique license purchased for each site. This is more secure than the ANSII and ISO standards that government department’s use as the Secugen Template is encrypted and the ANSII and ISO standards are not. The template data is useless and cannot be interpreted back into a usable fingerprint image. If this was not the case then there would be no world standards and performance measures for such technologies. The data is stored in an array in the RAM of the Biometric Controller and is also permanently stored on the hard drive of the Bio Controller to be restored in the event of a reboot.
Below is an example of a template code for an individual finger.
The solution is secure because the matching can only be done by the individual’s consent as the finger has to be presented to the device for matching. We do not hold images of fingerprints in our system.
The technology provided for this method of identification meets with BECTA guidelines and also allows students the option to opt out of the scheme and use a PIN number instead.
Also under the data protection act the school or caterer (the originator of the data) cannot allow access to this data by anyone for any other means than for the purpose the data was collected and that is to identify an individual within the solution we supply. Any biometric data that belongs to an individual that leaves the school is purged which also is in line with the BECTA guidelines.
