About Qsig (sign and verify images)
Enhance the Security and Authenticity of Your Digital Imagery with Qsig.
Can you spot a deep fake image?
Capture your photos with Qsig to ensure authenticity. Anyone can confirm they are genuine and unaltered.
In an era where photo-realistic deep fakes are proliferating online, establishing the veracity of digital images has become paramount. Qsig offers a robust solution to ensure the authenticity and integrity of your photos and images.
With Qsig, images captured or processed are embedded with a cryptographic signature. This signature serves as a powerful tool against digital manipulation, ensuring that the origins and authenticity of your images are verifiable. Utilize our public key verification system to confirm that the images you receive are indeed from a trusted source.
The unique feature of Qsig is its visual verification: a green signature watermark. When you observe this watermark on an image, it affirms that the image has remained unaltered since its inception and originates from the source you trust. Conversely, any alteration to the image, as minute as a single pixel change, results in the disappearance of the green signature, signaling potential tampering or manipulation.
Embrace Qsig to safeguard your digital imagery, maintain content integrity, and counteract the challenges posed by deep fakes.
