Witnus

The Witnus app lets you prove your point by creating Digital Witnesses. A Digital Witness is like a human one, only with perfect recollection and memory.

Here's how it works: When something happens that you want to be able to prove in the future - your car gets dented, you come up with a great idea, or anything unexpected or unusual happens to you - you fire up the Witnus app and snap a photo or record a short video clip. The photo or video is then uploaded to our servers, and we create a Digital Witness for you.

The Digital Witness uses math and logic to prove that the picture or video is guaranteed to not have been altered since it was uploaded, and it includes information about the timestamp and the location where it was created. To make this whole thing super secure, your Witness is also locked using blockchain transactions.

If you need to prove what your image or video claims, the app lets you share your witness with other people. A shared witness can be viewed in a web browser, complete with the image or video you created and with instructions on how to validate the information. And you're in control, you can stop sharing your witness whenever you want. Or delete it entirely if you prefer.

The Witnus app is created by iDefendo, a company that specializes in evidence creation and intellectual property protection. Our products and services are used by law firms and legal departments of companies around the globe.
