Signature verification

[Mayur2007]

Hello,

Can someone give me idea how to do signature verification using php / javascript / html5 ?
For eg I am using iphone and and generating signature over there. Now I need to compare this signature with previous one (which is available in php application / database). Like a login password.
can someone please help me?

Regards,
Mayur

This is a very advanced subject and it would be a lot easier to find and use an existing library rather than trying to reinvent the wheel.
