I am working on a php project to authentic users i.e to allow users to sign in and sign out using the scanner. I want to use a digital persona finger print scanner. How can i achieve that using php for authentication.?
Not sure you can -- do you have any idea how it transmits/stores it's data and where? Is there an application you have to make a passthrough too? Last time I saw someone doing something like that they had to run an executable from PHP, and in doing so they opened a bigger security hole than the biometrics were trying to plug over just putting up a keyboard and display for a regular password. After all, there's a reason laptops STOPPED coming with fingerprint scanners; they were unreliable, insecure, and the software side of it made things less secure. Their SDK lists these as the existing API targets: NET, Java, C#, ActiveX/COM, C/C++, JPOS/OPOS So for PHP I think you'd probably have to call one of those as an executable; and really that's not something I'd do. Could simply be PHP is the wrong language for the job. (It happens) as you may need device-level access PHP doesn't provide (for good reason being a scripting language where code elevations are easy-peasy) I'm assuming you dropped the $250 on a developer kit and have the SDK? You might also try asking on THEIR forums: http://devportal.digitalpersona.com/index.php Since you'll be much more likely to find people with experience with that device in there.
