New GenKey BioHASH SDK supports advanced biometric key and signature creation

GenKey has released a new version of its Biometric BioHASH SDK to enhance the user privacy and information security of small and large-scale enrolment and verification projects.

The new BioHASH-D release provides support for Biometric Asymmetric Key Creation and the Elliptical Curve Digital Signature Algorithm (ECDSA). Asymmetric encryption can be used to verify the origin and authenticity of data by generating a digital signature with public and private key pairs, with only the user or device storing the private key able to generate a valid signature. The new functionality embedded in the BioHASH SDK generates a private key from biometric fingerprint data, and discards the data after the key is used. The private key is generated separately each time, rather than stored, making it very difficult for attackers to target. GenKey says the functionality is a breakthrough unique to its technology, made possible by a new approach to fingerprint feature extraction and close integration with cryptographic primitives.

EDCSA signatures are used in a wide variety of applications, and allows BioHASH users to generate a standardized signature with a fingerprint for fully private biometric authentication, according to the announcement.

“Our latest release truly builds a bridge between robust biometric verification and advanced cryptographic functionality,” says GenKey Director of Technology Dr. Tom Kevenaar. “It can support secure client/server biometric authentication protocols that keep the biometrics safe even when a server is compromised by hackers. Additionally, this enhanced SDK offers a fascinating opportunity to extend Self-Sovereign Identity (SSI) solutions with a biometric proof-of-presence.”

“Legislations like Europe’s GDPR have underscored the importance of Privacy-by-Design as an intrinsic mechanism for creating secure biometric solutions,” comments GenKey CEO Michiel Loeff. “As a pacesetter in the biometric ID market with more than 10 years of experience in applying Privacy-by-Design principles, we are proud to announce a second-generation technology with unique characteristics for safeguarding individuals’ privacy.”

GenKey also released a new version of its ABIS for faster and more accurate matching earlier this year.
