Learn how to digitally sign your images with our simple and secure process, ensuring authenticity and integrity.
A signed image is an image that has been digitally authenticated using a digital signature, providing proof of authenticity and integrity.
Signing an image ensures that it is verified, untouched, and that its origin can be traced back to the authentic source. It protects against image tampering.
You can sign an image by uploading it to our platform, where we apply a secure digital signature. This process ensures the image's authenticity and non-repudiation.
Signed images are cryptographically secure, ensuring that the signature cannot be forged. Only the rightful owner of the private key can sign the image.
Signed images are legally recognized in many countries, particularly for intellectual property protection, digital contracts, and authentication purposes.
The image is hashed to create a unique fingerprint. The hash is then encrypted with the private key, and the recipient can verify the signature using the public key.
