ANTI FORGERY

A system based on encryption algorithm which generates a univocal barcode

Everytime a retail outlet issues a ticket, the central server authorizes the transaction by assigning a univocal code to it, which is associated to the sold ticket.

The univocal number on each ticket is cross-checked with the ticket price which generates, based on an encrypton algorithm which has been worked out especially for this purpose, a barcode which is printed on the front of the ticket, making any attempt to forgery practically impossible.

At the moment of checking the ticket, the operator uses a small laser tool (that looks like a mobile phone), equipped with a decoding software; the barcode is scanned by this tool and the barcode information (ticket number and price) is displayed on the monitor. This way the operator can check that the data printed on the ticket match with the displayed information, and obtain a certain proof of authenticity.
