There is a very simple but effective solution - steganography. welcome
Нужен спуфер фото который меняет файл так чтобы картинка осталась та же, а сам файл уже другой, тз пока еще не точное, но чатгпт предложил такое (не знаю насколько это реализуемо):
1. AI-Based Pixel Noise Injection
Use a diffusion or GAN model to make ultra-subtle pixel changes invisibly.
Tiny shifts in noise, gradients, or micro-contrast that humans can’t detect.
Model must be constrained to preserve structural and perceptual integrity (use LPIPS or SSIM metrics).
2. Hash & Fingerprint Randomization
All known hashes must be broken:
MD5, SHA-1, SHA-256, Perceptual hash (pHash), Average hash (aHash), Difference hash (dHash)
Ensure no hash collision with original file.
Implement logic to randomize via:
Invisible pixel shift
Bit flipping in compressed stream
Chromatic aberration simulation (at imperceptible level)
3. EXIF / Metadata Spoofing
Strip original EXIF and replace with randomized values:
Camera model, timestamp, GPS, ISO, focal length, etc.
Optional toggle: fake metadata to simulate iPhone, Android, DSLR, etc.
4. Compression Artifacts Variation
Run each file through an AI-controlled recompression pipeline:
Use slightly different quality levels (92–100)
Add minor JPEG quantization table tweaks
Change file entropy (padding + markers)
5. File-Level Randomization
Pad image with non-visual bytes
Add randomized dummy chunks (e.g. in PNG format)
Shuffle byte ordering where it doesn’t affect rendering
🧠 AI Models Suggested:
Use stable diffusion or ControlNet for pixel-preserving perturbations.
Use DCT-aware generative models for subtle JPEG-level changes.
Optionally, use LPIPS loss to verify visual similarity after spoofing.

Hello!
I can implement an AI-spoofing photo tool that changes the file itself (hash, metadata, entropy) but visually retains the same image. The implementation will include:
Invisible pixel changes via AI (Stable Diffusion/ControlNet)
Perceptual and cryptographic hash cracking (pHash, SHA256, etc.)
Forgery or deletion of EXIF metadata
Recompression of JPEG/PNG with variations (tables, entropy, padding)
Unique result without quality loss
📦 The result is a file that is not detected as a duplicate, not tracked by hashes, and looks identical to the original.
⏱ Deadline: 3–5 days
💰 Estimate: from $300 for MVP (CLI/Web, 1–2 formats)
Ready to make a demo file — write which format and scenario need to be tested.

Good day, very interested in working with you. I urgently need to gain experience working with the service.
I suggest discussing the work details in a private chat.
