An Indian-origin US researcher professor Anil Kumar Jain from Michigan State University (MSU) and his team have invented life-size 3D hand models. He with the help of his team using a high-resolution 3D printer have invented a life-size 3D hand model having a complete set of five fingerprints that can generate the same edges and gorges as real fingers of human do. "This is the first time a whole hand 3D target has been created to calibrate fingerprint scanners," said the professor.
Like any other optical gadgets, the fingerprint sensors and hand scanners need to be adjusted, with the lack of standard strategy; scientists are not able to calibrate it. But the scientist, Anil Jain, and his team have become able to create a full hand with the enrichment of advanced 3D printer. Speaking on the research, “We wanted to answer the question that has plagued law enforcement and forensic science for decades: Is fingerprint pattern persistent over time?” said the professor, adding that “we have now determined, with multilevel statistical modeling, that fingerprint recognition accuracy remains stable over time".
Prof. Jain and his biometrics team were investigating the methods to test and calibrate fingerprint scanners commonly used across the globe at police departments, airport immigration counters, banks and even amusement parks.
However, the Professor discovered this may not be as far-fetched as once thought and requires the security companies and the public to be aware. Jain while cautioning the public said that, with the fuse of one’s fingerprint and advanced 3D printer technology, such replica can be produced and can be used for illegitimate purpose. "As a byproduct of this research, we realized a fake 3D hand, essentially a spoof, with someone's fingerprints, could potentially allow a crook to steal the person's identity to break into a vault, contaminate a crime scene or enter the country illegally," Jain cautioned.
Along with Prof. Jain, the novel research is co-authored by another Indian-origin US researcher Sunpreet Arora, MSU doctoral student. The study is endorsed by the US National Institute of Standards and Technology (NIST).
