Authentication.

In the law of evidence, the act or mode of giving authority or legal athenticity to a statute, record, or other written instrument, or a certified copy thereof, so as to render it legally admissible in evidence. Verifications of judgements. An attestation made by proper officer by which he certifies that a record is in due form of law, and that the person who certifies it is the officer appointed so to do. Acts done with a view of causing an instrument to be known and identified. See also Verification.
Authentication of a writing means (a) the introduction of evidence sufficient to sustain a finding that it is the writing that the proponent of the evidence claims it is or (b) the establishment of such facts by any other means provided by law. Calif.Evid.Code, § 1400.
The requirement of authentication as a condition precedent to admissibility of evidence is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims. Fed.Evid.Rule 901.

Identification. - Black's 6th

Proof of identity. The proving that a person, subject, or article before the court is the very same that he or it is alleged, charged, or reputed to be; as where a witness recognizes the prisoner as the same person whom he saw committing the crime; or where handwriting, stolen goods, counterfeit coin, etc., are recognized as the same which once passed under the observation of the person identifying them.
The requirement of identification as a condition precedent to admissability is satisfied by evidence sufficient to support a finding that the matter in question is what its proponent claims. Fed.Evid.R. 901.
