This week’s blog we are going to be going over in more detail of how our system does not store any biometric data. Now as stated before we cannot tell you the exact process of how we do not store biometric data and how a finger print can’t be produced from the information stored. We can however give an overview of this process and also explain how other systems store biometric information.
Let’s start off with some biometric systems that do store biometric information. The first is storing an image of a finger print. This type of system (usually optical readers) captures an image of a finger print that it uses to compare to. These systems can be fooled with fake fingers easily, plus actual fingerprints can be accessed from the database.
Finger print matrixes. These systems take different amount of measurements to make a comparison to an actual finger print later on during the identification process. These measurement matrixes are stored on the system. Even though they are a little more secure than storing an image of a finger print they can still be easily reverse engineered to produce a finger print. Don’t be fooled by companies selling a system that stores matrixes and says they are safe. They still are storing biometric data.
Now a system that does not store biometric data. How it works (without giving away any secrets) is when enrolling, the system will do a varying number of measurements based on pattern. These measurements are put into an algorithm and out comes a long number. This number is then coded and stored only on your system. If someone were to “hack” into your server, decoded this number and handed it to our programmers they would not be able to produce a finger print. (Now I know what you are thinking, doesn’t that sound like a fingerprint matrix?) Unlike matrixes there is just not enough information stored because it is all incomplete. Much like being given a word than asked which book did that word come from? Only when the actual live finger is on the reader can the system make the comparison to associate the information and find a match. Putting together the pieces of the puzzle. When the finger is not on the reader it is missing way too much info to make sense out of anything.
