Handwritten signature recognition whether there is a third-party interface

my project needs a function: users may sign online (on paper) and sign twice online. We need to take two signatures into pictures and upload them to the website, and identify that the two signatures were done by the same person. Is there any php code or third-party interface information in this respect

?
