    Unanswered: Looking to make a database of fingerprints

    I work as a computer repair tech for my company and have been offered the opportunity to do a project. I'm looking to make a database of about 2000 peoples fingerprints (2 copies of each finger). We have Microsoft SQL Server but I have no Idea where to start. The vision is, to have an RFID scanner and have everyone swipe their badge then scan their prints and it automatically associates their prints with the badge number. Is there an easier or more simple way to do this or do you have any pointers on where to start? any help will be greatly appreciated. Thanks.

    Are you sure you know how much work this is? I haven't worked with fingerprints, but you cannot assume that the fingerprints are equal, so you have to create some kind of a pattern matching algorithm, or get one. My best advice (if you only are going to use this solution internally) is to leave it, and buy a complete solution doing this. I call that would be way cheeper (but not so interresting of course).

    if u r looking for the logic of fingerprint matching it is complex and at the same time standard. and this is not the place wher u will get it. however, if u r interested in saving fingerprints (or any image for that matter) in sql server u can use "image" type field.

    I am not looking to recall things from the database using fingerprints, just looking to input them. The central office has that algorithm so if they need to use it, All I have to do is give them access to the database

    for saving fingerprints, as i said, u can create a table with a image type field. access to sql server is normally available to all machines in network having sql client installed. of course there are many finer aspects of access to database which can be considered at a later stage.

    Of course you can use a image field, but that does not solve the case of looking up the images later on. When you have to check the fingerprint, you'll then have to return ALL the fingerprints to the client, for the client to decide if it matches. Matching fingerprints may seem easy at first, but i'ts actually a rather complex task. So, I rest my case. Leave it to someone who's done it before, unless you have both time and money to spend.
