From Subsection 117.05(5) of the Florida Statutes A notary public may not notarize a signature on a document unless he or she personally knows, or has satisfactory evidence, that the person whose signature is to be notarized is the individual who is described in and who is executing the instrument. A notary public shall certify in the certificate of acknowledgment or jurat the type of identification, either based on personal knowledge or other form of identification, upon which the notary public is relying.

Personally Known "Personally known" (by Notary Public) means having an acquaintance, derived from association with the individual, which establishes the individual's identity with at least a reasonable certainty.
