CLIP2Protect: Safeguarding Facial Privacy in the Age of Advanced Face Recognition Technology

Title: Protecting Facial Privacy: Introducing CLIP2Protect for Online Platforms

In the 90s sci-fi movies, we saw computers displaying rotating profiles of individuals with detailed information. The concept of face recognition technology, once considered futuristic, has now become a reality. However, concerns about privacy have arisen. As a result, the research community has been actively working on developing facial privacy protection algorithms. One such innovative method is CLIP2Protect, which aims to strike a balance between privacy preservation and visual fidelity.

1. The Significance of Facial Privacy Protection Algorithms:
Facial privacy protection algorithms are essential in safeguarding individuals’ identities and preventing unauthorized identification or tracking. It is crucial to maintain the usability of facial images while ensuring that the protected images cannot be tricked with fake faces.

2. Limitations of Existing Methods:
Existing methods, such as adversarial makeup-based techniques, suffer from drawbacks like makeup artifacts, dependence on reference images, and the need for retraining for each target identity. These shortcomings highlight the need for a reliable and efficient method to protect facial privacy.

3. Introducing CLIP2Protect:
CLIP2Protect is a cutting-edge solution for protecting facial privacy on online platforms. It utilizes a generative model to search for adversarial latent codes in a low-dimensional manifold. These codes are then used to produce high-quality face images that maintain a realistic identity while deceiving face recognition systems.

Features of CLIP2Protect:

– Adversarial Makeup Transfer: CLIP2Protect employs textual prompts to facilitate adversarial makeup transfer, allowing the generation of transferable adversarial latent codes. This technique conceals attack information within desired makeup styles without the need for extensive makeup datasets or retraining for different target identities.

– Identity-Preserving Regularization: CLIP2Protect ensures that the protected face images visually resemble the original faces by introducing an identity-preserving regularization technique. This technique focuses on optimizing only the identity-preserving latent codes, maintaining the perceived identity of the individual.

– Naturalness and Fidelity: To guarantee the naturalness and fidelity of the protected images, CLIP2Protect restricts the search for adversarial faces within the clean image manifold. This restriction helps prevent the generation of artifacts or unrealistic features that could be easily detected by humans or automated systems.

CLIP2Protect is a novel approach that effectively protects facial privacy on online platforms. It addresses the limitations of existing methods by utilizing adversarial makeup transfer and identity-preserving regularization techniques. By leveraging textual prompts, users can specify desired makeup styles and attributes, offering greater flexibility. Extensive experiments have demonstrated CLIP2Protect’s efficacy against face recognition models and online facial recognition APIs.
