MADDÉ: Model-Agnostic Deepfake Detection and Explainability

Motivation

In recent years, deepfakes have emerged as a prominent and concerning development in the fields of media and artificial intelligence [1]. With advancements in generative models, the creation of synthetic content is becoming more sophisticated, making it increasingly challenging to distinguish real from fake [2], [3]. The implications of this technology are vast, impacting areas like misinformation, security, and personal privacy [4], [5]. As deepfake techniques evolve, so too must our detection methods [6]. Addressing this issue is essential to maintain trust in digital media and protect against malicious misuse of synthetic content [7].

What We Are Doing

In the current deepfake research landscape, we identify two crucial areas for the future development of deepfake detection systems:

1. Pattern Detection
   The ability to detect patterns across various types of generative models is critical in deepfake detection [8], [9]. Generative techniques are rapidly advancing, with models like GANs, autoencoders, and more recently, diffusion models, each introducing unique artifacts and synthesis characteristics [10]. Identifying common patterns across these diverse generative methods is essential for building robust and generalizable detection systems that are not limited to a specific model type [11]. This approach is necessary to future-proof deepfake detection as new generative techniques continue to emerge [12].
2. Explainability
   Explainability in deepfake detection models is vital, as it enhances trust in the detection process and provides clear insights into how the model arrives at its decisions [13], [14]. Given the potential societal impact of deepfakes, it is crucial that detection models not only achieve high accuracy but also offer interpretable outputs that allow users to understand why a particular image or video has been classified as fake [15]. This explainability is particularly important in applications involving law enforcement, media verification, and public safety, where transparency is key to ethical AI use [16].
