Digital Witnesses and Evidence Binders

At the core of iDefendo is our patent pending technology that mathematically binds the content of a file to a timestamp and to a signature that identifies the author of the file. Our Digital Witnesses™ are built on top of that technology and leverage the power of blockchains to make the information immutable. Multiple Digital Witnesses are collated with extensive logging data to make up Evidence Binders™; neatly formatted evidence packages that contain everything you need to prove your side of any story.
