Google’s Gemini Nano model has powered a new AI photo-editing tool called Nano Banana that’s taken social media by storm, especially on Instagram. This innovative tool transforms ordinary selfies into retro-style images featuring women in traditional sarees, complete with classic Bollywood-inspired backdrops.
How Does Nano Banana Work?
Nano Banana uses advanced AI technology to convert your selfie into a 3D figurine-style image. The edited images often showcase smooth, almost plastic-like skin, large cartoonish eyes, and exaggerated proportions. Initially, users enjoyed the cute figurine effect, but the tool later added a unique feature that transforms these into vintage saree edits — giving photos a nostalgic, Bollywood movie poster vibe.
Privacy and Security Concerns
Despite Google’s assurance that every AI-generated image from Gemini Nano carries an invisible digital watermark called SynthID embedded within the metadata (to help identify AI-created content), several issues remain:
-
The tools to verify these watermarks aren’t publicly available yet.
-
Watermarks can be easily removed or ignored.
-
Experts warn that relying solely on watermarks is insufficient to prevent misuse of AI-generated images.
Users have also reported strange anomalies. For example, one user noticed an unusual mole on her left hand in the AI-generated image — which was not present in her original photo. Such glitches raise valid concerns about the reliability and safety of these AI tools.
Tips for Using AI Tools Safely
If you’re planning to try Nano Banana or any AI photo-editing tools, keep these safety tips in mind:
-
Avoid uploading sensitive or private photos. Protect your personal privacy by not sharing images that reveal sensitive information.
-
Remove metadata before sharing. Delete location tags and other metadata that can track your photos.
-
Review app permissions. Limit unnecessary access to your camera or gallery.
-
Read privacy policies carefully. Understand how your data is stored and used.
-
Use protection tools like Glaze or Nightshade. These add subtle “noise” to your images, making it harder for AI systems to scrape or misuse your photos.
Final Thoughts
While Nano Banana offers a creative and fun way to transform your selfies into eye-catching, retro-themed photos, it’s crucial to stay cautious about privacy and security. AI-generated images can be easily manipulated or misused, so always think twice before uploading your personal photos.
