Problem
Digital images are easily copied and altered, making it difficult to prove original ownership or authenticity when they are shared online.
Solution
Autograph embeds a cryptographic signature directly into an image, creating a tamper‑proof link to a blockchain record. The signature is displayed automatically on the image, allowing anyone to verify its provenance without needing special tools. Users can upload and share signed images on any platform, and the verification data remains accessible from any location. The service is offered for free, providing a forge‑resistant method for authenticating visual content.
Target Audience
Primary users are creators, photographers, and brands who need to protect and prove the authenticity of their visual assets when distributing them online.
