Workshop on  Generative, Adversarial and Presentation Attacks In Biometrics (GAPBio) 

Synthetic content creation has advanced rapidly in recent years due to deep learning. Newer architectures like Generative Adversarial Networks (GANs), Diffusion models, and Large Language Models (LLMs) can now produce ultra-realistic visual and textual content, from images and videos to highly coherent and persuasive text, challenging human perception and comprehension. While such realism is welcomed in sectors like entertainment and education, it also poses severe threats to secure access control systems in biometrics and to the integrity of digital information channels. Image and video manipulation attacks have evolved to defeat traditional biometric systems, with morphing attacks compromising multiple identities through a single manipulated image, and DeepFakes spreading misinformation or impersonating individuals. LLM-generated text further amplifies these risks by enabling sophisticated phishing, social engineering, and disinformation campaigns. Attack strategies now combine both traditional manipulation techniques and recent adversarial machine learning approaches (e.g., GANs, Diffusion, LLMs). To address these challenges, several governmental agencies are funding research for reliable detection and mitigation solutions.

The workshop is planned to report the advancements in creation, evaluation, impact and mitigation measures for adversarial attacks (soft and hard attacks) on biometrics systems. The workshop also targets submissions addressing the analyses and mitigation measures for function creep attacks. This half-day workshop is a seventh edition of the special session, previously held in conjunction with BTAS-2018, WACV-2020, WACV-2021, WACV-2022, WACV-2023, WACV-2024 and WACV-2025 respectively.  

Papers are invited to report on following topics, but not limited to:

• • Physical attacks on biometric systems (e.g., mask, spoofing).

  • Image manipulation attacks in biometric verification and identification (e.g., PAD).

  • Video manipulation attacks affecting biometric systems.

  • Morphing attacks and their detection.

  • Generalizable and robust attack detection algorithms.

  • Forensic behavioral biometrics for identity verification.

  • Soft biometric cues for authenticity assessment of biometric data.

  • Multimedia forensics applied to biometric systems.

  • Integrity verification and authentication of digital content in biometrics.

  • Multimodal decision fusion for enhanced authenticity verification.

  • Function creep attacks compromising privacy in biometric systems.

  • Human perception and decision-making in biometric data authenticity verification.

  • Ethical, legal, and societal implications of emerging manipulations, including AI-generated content.

  • Case studies illustrating the above topics, including attacks leveraging GANs, Diffusion models, or LLMs.

Submission Guidelines:

ACKNOWLEDGEMENT: The Microsoft CMT service was used for managing the peer-reviewing process for this conference. This service was provided for free by Microsoft and they bore all expenses, including costs for Azure cloud services as well as for software development and support.

• Papers presented at the WACV workshops will be published as part of the "WACV Workshops Proceedings" and should, therefore, follow the same presentation guidelines as the main conference. Workshop papers will be included in IEEE Xplore, but will be indexed separately from the main conference papers. Paper submission guidelines of WACV can be accessed through this link.

• For review, a complete paper should be submitted using the review format and the guidelines provided in the author kit. All reviews are double-blind, so please be careful not to include any identifying information, including the authors’ names or affiliations. 

• Accepted papers will be allocated 8 pages in the proceedings. Please note that References/Bibliography at the end of the paper will NOT count toward the aforementioned page limit. That is, a paper can be up to 8 pages + the references. 

• The submission template can be downloaded (Overleaf template, ZIP Archive).

• Please submit your papers under this CMT link.
