SignatureAuth: Augmented Real and Fake Signatures Dataset for Authentication

Description

Seventy five study participants provided a total of 332 unique signatures. The data collection gathered 1,328 authentic signature samples by collecting 4 natural variations for each participant's unique signatures. Then, 8 other randomly sampled participants (excluding the person providing the original four signatures) collected 8 forged signatures (one per participant) from each original signature, generating a total of 2656 forged samples. Then signatures were augmented with a total of 147,408 signatures where 147,408 were augmented  signatures.
