On the Impossibility of Three-Move Blind Signature Schemes
We investigate the possibility to prove security of the well-known blind signature schemes by Chaum, and by Pointcheval and Stern in the standard model, i.e., without random oracle...

Multi-scale Structural Saliency for Signature Detection
Detecting and segmenting free-form objects from cluttered backgrounds is a challenging problem in computer vision. Signature detection in document images is one classic example an...

Signature-Based Document Image Retrieval
As the most pervasive method of individual identification and document authentication, signatures present convincing evidence and provide an important form of indexing for effectiv...

Forward-Secure Threshold Signature Schemes
We consider the usage of forward security with threshold signature schemes. This means that even if more than the threshold number of players are compromised, some security remain...

Simulation-Sound NIZK Proofs for a Practical Language and Constant Size Group Signatures
Non-interactive zero-knowledge proofs play an essential role in many cryptographic protocols. We suggest several NIZK proof systems based on prime order groups with a bilinear map...
