AuthSig: Safeguarding Scanned Signatures Against Unauthorized Reuse in Paperless Workflows

arXiv — cs.CVThursday, November 13, 2025 at 5:00:00 AM
As the trend towards paperless workflows deepens, the reliance on electronic signatures is increasing, yet static scanned signatures remain common due to their convenience. However, these signatures are vulnerable to malicious copying and reuse, raising significant security concerns. To combat this issue, the novel AuthSig framework has been proposed, which utilizes generative models and watermarking techniques to bind authentication information directly to the signature image. This approach not only enhances the security of electronic signatures but also enforces a One Signature, One Use policy, effectively mitigating risks associated with unauthorized reuse. Furthermore, AuthSig employs a keypoint-driven data augmentation strategy to improve the diversity of signature styles, achieving over 98% extraction accuracy even under various distortions. This advancement is vital for maintaining the integrity of identity verification in an increasingly digital world, ensuring that as workflow…

The paper titled 'Towards Uncertainty Quantification in Generative Model Learning' addresses the reliability concerns surrounding generative models, particularly focusing on uncertainty quantification in their distribution approximation capabilities. Current evaluation methods primarily measure the closeness between learned and target distributions, often overlooking the inherent uncertainty in these assessments. The authors propose potential research directions, including the use of ensemble-based precision-recall curves, and present preliminary experiments demonstrating the effectiveness of these curves in capturing model approximation uncertainty.
