Application Description

Clapperboard offers a unique solution for recording videos and ensuring their authenticity through blockchain technology. This service allows you to use any camera, from CCTV to action cameras or even built-in drone cameras, to capture your footage. To leverage Clapperboard's features, you'll need to create an account and add funds to your balance.

Here's how you can secure an authentic video using Clapperboard:

Comment the Video: Add a comment to your video. This comment will be part of the authenticity verification process.
Request a QR-Code: Generate a unique QR-code through Clapperboard.
Show the QR-Code on Camera: While recording your video, ensure the generated QR-code is visible in the frame. This step is crucial for linking the video to the blockchain.

The QR-code and your comment will be permanently recorded on the NEM blockchain, providing a tamper-proof record of your video's authenticity and authorship. Once recorded, you can retrieve the video from your camera.

To verify that the video has not been altered and was indeed created after the QR-code was generated, you need to:

Upload the Video Fragment: Submit the part of the video containing the QR-code to the http://product.prover.io/ service.
Obtain the Certificate of Authenticity: If the verification is successful, you will receive a Certificate of Authenticity detailing the video's integrity and creation timestamp.
