Abstract
Detecting deepfakes involving face-swaps presents a significant challenge,
particularly in real-world scenarios where anyone can perform face-swapping
with freely available tools and apps without any technical knowledge. Existing
deepfake detection methods rely on facial landmarks or inconsistencies in
pixel-level features and often struggle with face-swap deepfakes, where the
source face is seamlessly blended into the target image or video. The
prevalence of face-swap is evident in everyday life, where it is used to spread
false information, damage reputations, manipulate political opinions, create
non-consensual intimate deepfakes (NCID), and exploit children by enabling the
creation of child sexual abuse material (CSAM). Even prominent public figures
are not immune to its impact, with numerous deepfakes of them circulating
widely across social media platforms. Another challenge faced by deepfake
detection methods is the creation of datasets that encompass a wide range of
variations, as training models require substantial amounts of data. This raises
privacy concerns, particularly regarding the processing and storage of personal
facial data, which could lead to unauthorized access or misuse. Our key idea is
to identify these style discrepancies to detect face-swapped images effectively
without accessing the real facial image. We perform comprehensive evaluations
using multiple datasets and face-swapping methods, which showcases the
effectiveness of SafeVision in detecting face-swap deepfakes across diverse
scenarios. SafeVision offers a reliable and scalable solution for detecting
face-swaps in a privacy preserving manner, making it particularly effective in
challenging real-world applications. To the best of our knowledge, SafeVision
is the first deepfake detection using style features while providing inherent
privacy protection.
