Authenticity

See also authenticity (philosophy) and authentication (which deals only with computer security).

In the arts, history, archaeology, the study of antiques, and similar fields involving unique or scarce artifacts from the past, and, with regard to documents in law, authenticity (Greek: αυθεντικός, from 'authentes'='author') is the truthfulness of origins, attributions, commitments, sincerity, and intentions; not a copy or forgery. See also provenance.

Webster's 1913 dictionary defines authenticity as

1. the quality of being authentic or of established authority for truth and correctness.
2. Genuineness; the quality of being genuine or not corrupted from the original.

In later writers, especially those on the evidences of Christianity, authenticity is often restricted in its use to the first of the above meanings, and distinguished from genuineness.
