Protecting your work and documents has become really important in this day and age. Thanks to technology, it's become quite easy to send information and even sensitive documents via email. The only problem though is that it's also very easy to duplicate content illegally if there's no proper way of authenticating them. If you want a guaranteed way of protecting your files, then check out XolidoSign. This simple but efficient software lets you add a timestamp or digital signature to your files so you can easily verify them. It also allows your recipient to verify the signature, ensuring that you are both receiving untampered documents.
