How to 'see' who has Shared / Liked your Web Page

Hello again,

I am looking for a way to add a function to the behavior of the Share / Like buttons that will allow me to ‘see’ who has Shared / Liked my Web Page.

Is there a way for me to populate an array or table with the ‘LinkedIn’ or ‘Twitter’ account names of those who have Shared / Liked my page?

Pleas let me know A.S.A.P.

Thank you.
