Image recognition is one of the most important fields of image processing and computer
vision. Food image classification is an unique branch of image recognition problem. In …

Designated verifier signature (DVS) allows a signer to convince a designated verifier that a
signature is generated by the signer without letting the verifier transfer the conviction to …

The notion of a Designated Verifier Signature (DVS) scheme allows a signer to create a
signature which is only verifiable by an intended verifier. DVS is a very useful scheme for …

Designated verifier signature (DVS) allows the signer to persuade a verifier the validity of a
statement but prevent the verifier from transferring the conviction. Strong designated verifier …

In this paper, we propose a new type of digital signatures which is specifically designed for
graph-based big data system. The properties of the proposed signatures are twofold. On one …

In an ID-based universal designated verifier signature scheme, a single signer generates a
signature that can only be verified by a designated verifier using a simplified public identity …

An attribute-based signature (ABS), is a cryptographic scheme where someone can sign a
message using any kind of predicates verified by the attributes he owns. For such scheme, it …

In this paper, we re-formalize the security notions of universal designated multi verifier
signature (UDMVS) schemes. Then the first UDMVS scheme is presented in the standard …

We give a generic construction for universal designated-verifier signature schemes from a
large class, ℂ, of signature schemes. The resulting schemes are efficient and have two …

The proxy signatures are important cryptosystems that are widely adopted in different
applications. Most of the proxy signature schemes so far are based on the hardness of …
