Face recognition and comparison

I want to detect and compare Face. There should be provision to save the images in database like sql server or MySql. The process should be like below Detect Faces and add it in database. So database will contain information about eyes,nose mouth, forehead information etc and File path and on the other hand keep the image in File System Second point is, you select any image and there will be a compare button to pick top x similar images from database. So similar images can be beard, tilt face or side face. if you want to use any third party, it should be open source only. I need this ASAP so if you have a source code, its most welcome.
