Abstract
Apparatus, system, and method for generating a synthetic finger are disclosed. A three-dimensional (3D) model of a fingerprint is generated based on fingerprint data received from a database. A mold is creating based on the 3D model. A casting material is applied on the mold to create a synthetic finger. The synthetic finger includes a fingerprint formed on the casting material by the mold.
Claims20
A method of generating a synthetic finger, the method comprising:
- receiving fingerprint data from a database;
- generating a three-dimensional (3D) model of a fingerprint based on the fingerprint data;
- creating a mold based on the 3D model;
- applying a casting material on the mold;
- and
- creating a synthetic finger comprising a fingerprint formed on the casting material by the mold.
A synthetic finger assembly, the synthetic finger assembly comprising:
- a substrate;
- a near field communication (NFC) circuit disposed on one side of the substrate;
- a synthetic finger disposed on the NFC circuit;
- and
- a foam material with a predetermined thickness disposed between the NFC circuit and the synthetic finger, wherein an adhesive is disposed between the substrate and the NFC circuit, between the NFC circuit and the foam material, and between the foam material and the synthetic finger.
A method of generating a synthetic finger, the method comprising:
- receiving fingerprint data from a database;
- generating a plurality of three-dimensional (3D) models of a plurality of fingerprints based on the fingerprint data;
- creating a mold based on the 3D model for each of the plurality of fingerprints;
- creating an array of molds by combining each mold for each of the plurality of fingerprints;
- applying a casting material to the array of molds forming a sheet of casting material;
- and
- segmenting the sheet into individual synthetic fingers, wherein the synthetic fingers comprise a fingerprint formed on the casting material by the mold.
