Although not PHP, this may also give you some pointers as to the relevant techniques :- http://itknowledgeexchange.techtarget.com/itanswers/how-to-compare-fingerprin t-images-in-vbnet/ Rob. -----Original Message----- From: php-objects@xxxxxxxxxxxxxxx [mailto:php-objects@xxxxxxxxxxxxxxx] On Behalf Of Shaikh Md. Zaid Sent: 03 April 2009 00:03 To: php-objects@xxxxxxxxxxxxxxx Subject: Finger Print comparision Hi There, I am developing an application which required biometric comparison (finger print comparison). I receive the user thumb print on a paper (form), I scanned it with high end scanner and then stored the same in an image file (if required I can also store this in database as blob data). The user can send the form again (filling a new form and giving his thumb print again on the form) and at that point before inserting it to in my database I want to make sure that this thumb print is not already there in my database. How can I compare those thumbprints taken at two different occasions. They can be on my file system or can be in my MySQL database. Considering the performance of the system I am ready to write a C++ or JAVA routine which would do this for me. This process will run in a separate space (out of memory allocated to Apache). Any pointers will help me. Thanks, -Zaid [Non-text portions of this message have been removed] ------------------------------------ Are you looking for a PHP job?
