“…This work, however, is focused on how to implement self-sovereignty but storing secret and biometric material in full user control rather than the generic scenario of ours which is enhancing current biometric systems with auditing capabilities of blockchains. A similar remark can be made for Nandakumar et al [7] which design a fairly complete system relying on private blockchains and mixing the blockchain's consensus layer with biometric material so that the decision of matching is distributed. This is further made secure by using secret sharing techniques such as Shamir's.…”

Biometric authentication, and notably using fingerprints, are now common. Despite its usability, biometrics have however a caveat which is the impossibility of revocation: once the raw fingerprint is breached, and depending on the technology of the reader, it is impossible to stop an illegitimate authentication. This places a focus on auditing both to detect fraud and to have clear indications that the fingerprint has been breached. In this paper we show how to take advantage of the immutability property of Blockchains to design an auditable protocol based on Diffie-Hellman key exchange with applications to fingerprint authentication.

A decentralized identity system that can provide users with self-sovereign digital identities to facilitate complete control over their own data is paramount to Web 3.0. The accounting system on blockchain is an ideal archetype for realizing Web 3.0 decentralized identity: users can create their accounts without registering with a central agent. Such an identity system is endowed with anonymity property: nobody knows the account's owner because the relationship between an account and the owner is invisible. Thus, user privacy is well protected even though the account's data is public. However, a disadvantage of such complete anonymity is that users can create multiple accounts without authentication to obfuscate their activities on the blockchain. In particular, the current anonymous blockchain account system cannot accurately register the social relationships and interactions between real human users, given the amorphous mappings between users and blockchain identities. Mistrust can be a major hurdle to the large-scale deployment of Web 3.0. This work proposes ZKBID, a zero-knowledge blockchain-account-based Web 3.0 decentralized identity scheme, to overcome endemic mistrust in blockchain account systems. ZKBID links souls (blockchain accounts) to humans (users) in a one-to-one manner to truly reflect the societal relationships and interactions between humans on the blockchain. With ZKBID, the users are accountable for their accounts anonymously, preserving privacy. ZKBID authenticates users using face match and then maps authenticated users to accounts. Zero-knowledge proofs encode the face match results, and user-account mappings employ linkable ring signatures to preserve anonymity. Importantly, ZKBID is fully decentralized: all user-related data are generated by users and verified by smart contracts on the blockchain. We implemented ZKBID and built a blockchain test network for evaluation purposes. Our tests demonstrate the effectiveness of ZKBID and suggest proper ways to configure ZKBID system parameters.

“…This method suffers from pixel expansion while reconstructing the image from the shares. In [49], authors used a one-time biometric token generated using basic VSS scheme for blockchain transactions. All these existing VSS schemes reconstruct the fingerprint images with either pixel expansion and/or a reduction (almost 50%) in contrast.…”

Fingerprint is the most recommended and extensively practicing biometric trait for personal authentication. Most of the fingerprint authentication systems trust minutiae as the characteristic for authentication. These characteristics are preserved as fingerprint templates in the database. However, it is observed that the databases are not secure and can be negotiated. Recent studies reveal that, if a person's minutiae points are dripped, fingerprint can be restored from these points. Similarly, if the fingerprint records are lost, it is a permanent damage. There is no mechanism to replace the fingerprint as it is part of the human body. Hence there is a necessity to secure the fingerprint template in the database. In this paper, we introduce a novel fingerprint template protection and fingerprint authentication scheme using visual secret sharing and super-resolution. During enrollment, a secret fingerprint image is encrypted into n shares. Each share is stored in a distinct database. During authentication, the shares are collected from various databases. The original secret fingerprint image is restored using a multiple image super-resolution procedure. The experimental results show that the reconstructed fingerprints are similar to the original fingerprints. The proposed method is robust, secure, and efficient in terms of fingerprint template protection and authentication.
