How to comparing a field of webform with the current user?

How can I filter a submission of a Webform, comparing a field of Webform with the current user? My Webform, including all the fields there is also that of the “recipient.” I want to do, it is to compare the views through a filter this field with the current user. In short, the aim is to allow only the person indicated on the form, to view this submission. I hope to have fully expressed my request. Thanks soo much!
