Title: Timestamp Functionnality with Universign

As a file sharing system, Ajaxplorer allow users to upload files and share them. For some files and mostly for business, it can be necessary to demonstrate that the file has not been changed since it's last upload. It can be mandatory for many type of files as contracts, meeting minutes, intellectual property,...

Without a specific tool, it is impossible to prove that the content of a document has not change, or a new version, different from the previous one, has been uploaded.
One of the way to legally protect your document, guaranteeing their legal value, integrity and authenticity is to use a authorized timestamp token.
This token will demonstrate that the document attached exists at a given time, without any changes.

For exemple if you use Ajaxplorer to share with customers, partners, suppliers documents like contract, quotes, business proposals, meeting minutes, graphic designs, or any kind of work, you will probably need to prove that the shared document exists at a given time and has not been changed since that date.

Using Timestamping means you have all the odds in your favor when it comes to reassuring the person you are dealing with of the accuracy of any dates given in a sensitive legal context.

If you business works with administration, it can be mandatory to use this kind of stuff. For that I am using the Universign services, which has the higher level of qualification in France, and offer an API, quite easy to use !
