A Trusted Digital Document is a digital or digitized document with improved security to prevent fraud. Trusted Digital Documents have the benefit that anyone can instantly verify beyond doubt when a document is issued, by whom and that it hasn't been altered since without the help of expensive digital forensic experts. This prevents fraud, makes auditing much easier, and improves trust in any digital relationship.
The difference between a Digital Document and a Trusted Digital Document is much like a website using Http or Https. And although most people have no idea what the Https stands for or how that exactly works, it has become common knowledge that it is better not to enter sensitive data such as personal or financial information when a website doesn't use https. And just like using https, the use of Trusted Digital Documents will become a best practice for the secure exchange of digital documents.
