Hidden Face – AI Privacy1.4.6 - App Store

Protect your privacy before you post.

This app helps you reduce facial recognition risks in photos and videos using advanced visual filters designed to disrupt AI-based detection systems - while keeping your content natural and shareable.

The app’s algorithm automatically detects all faces in a photo or video, and filters are applied to every detected face at once. You don’t need to select faces manually.

You can process both images and videos (maximum video length: 3 minutes) and apply adjustable filters with intensity sliders for full control over the final result.

For stronger protection, combining multiple filters at the same time is recommended. Layered effects often provide better masking performance than using a single filter alone.

FILTERS

AI Scramble
Adds controlled facial noise that interferes with recognition algorithms without changing face geometry.
- Subtle grain effect
- Adjustable intensity
- Keeps natural proportions

Spectrum Shift
Modifies color characteristics such as contrast, exposure, and saturation inside the facial area.
- Alters color signature
- No geometry distortion
- Natural look at lower levels

Pixel Guard
Applies structured pixel displacement to break spatial consistency between facial features.
- Disrupts feature alignment
- Noticeable but effective
- Designed against neural analysis

Smart Blur (T-Zone Mask)
Masks the most recognizable facial area (eyes and nose zone) while leaving the rest of the face more natural.
- Focused masking
- Less aggressive than full blur
- Suitable for social media

Global Shield
Adds digital adversarial noise across the entire image, affecting how AI systems interpret textures and patterns.
- Works on full photo
- Subtle visual impact
- AI-focused disruption

Face Warp
Introduces geometric micro-distortions that alter facial structure perception for machine vision systems.
- Geometry modification
- Still recognizable to humans
- Strong defensive effect

REAL-TIME MATCH ANALYZER

The built-in analyzer shows how similar the processed face remains compared to the original image.
It displays a Match % value so you can evaluate the transformation strength before exporting.

In most cases, reducing similarity by 60-70% already provides a strong level of protection.
It is not necessary to push filters to extreme levels. Balanced masking often delivers better results while maintaining a natural look.

IMPORTANT NOTE

AI and facial recognition technologies constantly evolve.
This app is designed to reduce recognition probability, but it does not guarantee 100% protection from all current or future systems.

Use responsibly and adjust intensity according to your needs.

PERFORMANCE DISCLAIMER

Filter performance and analyzer results may vary depending on image and video conditions.

Factors that can influence effectiveness include:

Original image quality and resolution

Lighting conditions (low light, strong backlight, shadows)

Camera focus and motion blur

Distance between the face and the camera

Face angle and partial occlusions

Lower-quality or poorly lit images may reduce both detection accuracy and filter precision.
