Random Multispace Quantization as an Analytic Mechanism for BioHashing of Biometric and Random Identity Inputs
TL;DR: The previously presented biometric-hash framework prescribes the integration of external randomness with user-specific biometrics, resulting in bitstring outputs with security characteristics comparable to cryptographic ciphers or hashes, which are explained in this paper as arising from the random multispace quantization of biometric and external random inputs.
Book ChapterDOI
Computation of cryptographic keys from face biometrics
Alwyn Goh,David Chek Ling Ngo +1 more
TL;DR: This work outlines cryptographic key-computation from biometric data based on error-tolerant transformation of continuous-valued face eigenprojections to zero-error bitstrings suitable for cryptographic applicability.
Journal ArticleDOI
PalmHashing: a novel approach for cancelable biometrics
TL;DR: The implementation details of PalmHashing are outlined, which offers several advantages over contemporary biometric approaches such as clear separation of the genuine-imposter populations and zero EER occurrences and its potentials in security-critical applications.
Journal ArticleDOI
Modelling interface aesthetics
TL;DR: A theoretical approach is proposed to capture the essence of artists' insights with 14 aesthetic measures for graphic displays that are important to prospective viewers and may help gain attention and build confidence in using computer system.
Journal ArticleDOI
Personalised cryptographic key generation based on FaceHashing
TL;DR: A novel two-stage technique to generate personalized cryptographic keys from the face biometric, which offers the inextricably link to its owner, with security comparable to cryptographic hashing of token and knowledge key-factor.
