all3DSignDB: A Unified Database and Benchmark for 3D Signature Verification

all3DSignDB is a unified benchmark database for 3D online signature verification, built by merging all publicly available 3D signature databases that provide explicit (x,y,z) coordinates: 3DIIT, captured with a Leap Motion sensor, and DeepAirSig, captured with an Intel Senz3D depth camera. The resulting database contains 120 users, 2,400 genuine signatures, and 1,266 skilled forgeries. Together with the database, a standardized evaluation protocol is provided — inspired by the SVC-OnGoing competition — including comparison files for 1vs1 and 4vs1 enrollment scenarios under both random and skilled forgery conditions. All comparison files are publicly shared to ensure reproducibility, along with a DTW-based baseline verifier, enabling fair and transparent comparison across future 3D signature verification systems.
