hi, i'm trying to develop a web application using asp.net and mssql,
i want a user to log in using fingerprint. pls help as I dnt even know where to start from
a sample code to store fingerprints in the database, read the fingerprints and compare to verify would be highly appreciated
thanks.

If I may ask, why fingerprint verification?

Here is what you will need:

1. An input device that scans the finger-print and passes the captured print to the application.
2. A finger-print sample for each authorized user to which to match the input from 1 (stored in a database table).
3. A pattern recognition library to perform the match operation in 2.

Maybe by the time you think about what you need to do this, you'll appreciate how much work you have ahead of you.

lol

Why would you want to log into a web application by fingerprint?
Except you're talking of an intranet where everyone has a fingerprint scanner hooked up to the network, your project is a non-starter.

Who wants to send something as personal as their fingerprint over HTTP (any protocol for that matter)?

there are so many ways to break into a web application. If you are not familiar with these hacks, your purpose of having a finger-print authorization is defeated.
you'd need to worry about securing your database, hardware, protocols and the likes.
if you wish to continue on your development however, research more on biometric applications

I don't think this is for security reasons alone

thnks all, 1nt 2 hlp a frnd develop an e-voting s/w for his final yr project & tot incoporatin fingerprint wld b cool

You need face recognition, not fingerprint. Face recognition is the worldwide standard for e-voting. If you are coding in C# and WPF I can give some help (well a great deal really).

face recognition for e-voting In what country is it a standard ?
Which even makes more sense? fingerprint or face recognition ?
funny idea really, the fact that its e-voting doesn't mean you have to be physically present to vote. If you are voting via telephone, how do you perform a facial recognition for that exercise ?

Charlie, don't bring yourself out na.

Lol . . . . don't know of Finger printing for e-voting either. I mean I can attest to the fact that finger printing is used in some places at voting boots and not facial recognition here.

Don't mind me jare.
But it really is becoming the standard (especially with the advent of 3D detection). You might do your normal fingerprinting, but never notice the camera. It has used extensively and very successfuly to cut out fingerprint manipulation in passports, drivers licenses, elections etc. If you have ever been asked for a picture ID (the don't smile or look sideways type), you now know what it was for.

For the purpose of fatezy's project, it should be relatively cheap to set up with a cheap webcam. Source code for 3D and other face recognition techniques is widely available on the web for download in various languages.

It is still not as widely used as fingerprinting technology when it comes to identification purposes. Fingerprinting in use for identification purposes is hard to find in most of northern america as it is in Nigeria. I was taken aback when I discovered that some schools in Nigeria use finger prints for grade school identification. Something that is considered a NO-NO in most all states out here. I know it is used in the UK but still with much resistance.

I am assuming this is some class project and not necessarily intended for commercial.

yea, lol, the idea wont fly in the US.

We could have taken advantage of this when we were all made to do a fingerprint during the national ID card scheme, and we all did it willingly. Imagine how the fingerprint database would have helped towards the nation's security. I mean we practically got the citizens' fingerprint on a platter of gold and mismanaged that asset. God is a merciful God sha (for those who defrauded that project). It would be difficult to implement now that people are wiser.
