You can create a trusted digital document by registering it with Dokkz. To register documents you do need an account.
If you have an account, please log in with your username and password and go to the "Register" page. Drag and drop the files you like to register or select them on your computer with the link "select a file on your desktop". All you need to do next is add a description to the file(s) for context. This description is displayed when the file is validated by third parties and is used as a folder header in your personal overview. When you're done, click the orange "Register" button and you're done.
