Post-Quantum Secure Identity-Based Proxy Blind Signature Scheme on a Lattice

open access: yesEntropy, 2023
Blind signatures have been widely applied when privacy preserving is required, and the delegation of blind signature rights and a proxy blind signature (Proxy-BS) become necessary when the signer cannot sign.

Partial blind signature scheme based on SM9 algorithm

open access: yes网络与信息安全学报, 2021
Ordinary digital signatures have many deficiencies in effectively protecting users' privacy, and signature repudiation and tracking occur from time to time. In order to solve the above problems, a partial blind signature scheme based on the SM9 algorithm

Determinant-preserving blind signatures from Hadamard-type t-Jacobsthal–Leonardo sequences [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this paper, we introduce a new class of sequences called the termed Hadamard-type t-Jacobsthal-Leonardo sequence which is generated by applying a Hadamard-type product to the characteristic polynomials of the t-Jacobsthal and Leonardo sequences.

New Construction of Blind Signatures From Braid Groups

open access: yesIEEE Access, 2019
A new construction of a blind signature scheme based on braid groups is proposed. In the random oracle model, the proposed scheme is provably unforgeable against chosen message attacks, assuming that the one-more matching conjugate problem in braid ...

A biometric‐based verification system for handwritten image‐based signatures using audio to image matching

open access: yesIET Biometrics, 2022
Signing a document or a cheque by hand or using a stored image‐based signature is known to be a valid method for authentication and authorisation by the signer. However, signature forging has advanced to replicate exactly how a signature looks, which can

Blinding for Unanticipated Signatures [PDF]

open access: yes, 2010
Previously known blind signature systems require an amount of computation at least proportional to the number of signature types, and also that the number of such types be fixed in advance. These requirements are not practical in some applications. Here, a new blind signature technique is introduced that allows an unlimited number of signature types ...

Blind Hyperspectral Unmixing Using Autoencoders: A Critical Comparison

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Deep learning (DL) has heavily impacted the data-intensive field of remote sensing. Autoencoders are a type of DL methods that have been found to be powerful for blind hyperspectral unmixing (HU). HU is the process of resolving the measured spectrum of a

A Threshold-Blind Signature Scheme and Its Application in Blockchain-Based Systems

open access: yesIEEE Access
In blockchain-based systems usually there are two common concerns: one of them is privacy and other is key management. Besides privacy has been widely studied, nor key management has been done so deeply, moreover, the conjunction of both neither has be ...

A new lattice-based partially blind signature with more complete proof

open access: yesJournal of Information and Intelligence
Partially blind signatures are introduced on the basis of blind signatures, which not only retain the advantages of blind signatures, but also solve the contradiction between anonymity and controllability in blind signatures.

Transcriptomic analysis of the Brazilian blind characid, Stygichthys typhlops, reveals convergent selection with Astyanax mexicanus and other cavefishes

open access: yesFrontiers in Ecology and Evolution, 2023
Molecular studies have shown that Neotropical fishes of the order Characiformes have undergone two independent events of cave colonization. Among these fishes are the Mexican blind cavefish (Astyanax mexicanus), a well-studied model system for cave ...
