Leap Signature Dataset (LSD)

The Leap Signature Dataset (LSD) consists of signatures from 60 unique subjects in the form of 3D signature trajectories. The trajectories are captured in 3D space without any tactile feedback using a Leap Motion device. The data for each subject consists of 12 samples of genuine signatures and 3 samples of impostor signatures. The data for each subject is captured in a single session. The Leap Signatue Dataset was captured along with the face identities of the subjects. However, to protect the identities of the subjects, we have provided the Leap Signature samples only.

The database can be downloaded from the following link:
