9. Ours: Certified eDocument Authority Service
Instead of having to the signed document to all recipients individually, this service takes care of the entire signing workflow
At the end of the process, all parties receive the final signed document that has been signed by all those parties
Via this service on web or mobile, we easily sign a PDF/Office/XML with multiple parties

Service
Once got the CeDA card and install the middleware, on the first login, we have to confirm the address and some personal/company information 01
The system sends you an containing a link for confirmation purposes. After confirmation, we can do all of stuffs on CeDA 02 03
Once document is defined by a title, the signing document that we upload, and a list of recipient addresses
After creating the document within a system, all recipients receive an containing a personal contact signing request 04
How Does It Work?

11. Ours: Certified eDocument Authority
Service 05
Via the signing request, we can add a digital signature to the signing document
When all recipients have the signed document, a last is being send to all recipients containing the final signed document 06 07
At this point, the document owner can safely remove the document from the CeDA
The document owner can also poke all recipients that did not yet signed the document 08
How Does It Work?

12. Ours: Certified eDocument Authority Service
Is It Secure?
If the guy don’t start to forward document signing request to each other, the system is 100% secure. Of course, similar to guy forwarding the document signing requests, then of course other guy can view the document too
Only guy receiving a document signing request can eventually view the content of the document. Of course, the document owner can also view their documents

13. Ours: Certified eDocument Authority Service
How Is About
Concurrent Signing?
It can happen that two recipients sign a certain document at the very same time. In the event that this happens, only one of them will 'win'. The other will receive an error message asking him/her to retry it again later on
This mechanism thus ensures that we end up with a signed document containing multiple valid signatures
