I need to find a solution for one of my clients who is asking me to implement a esignature solution. I was thinking of suggesting some solutions like DocuSign or EchoSign.
But recently my client said he wants a closed system esignature.
I searched some sites and i found out the difference between closed system and open system esignature.
http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfCFR/CFRSearch.cfm?CFRPart=11&showFR=1
The Closed system means an environment in which system access is controlled by persons who are responsible for the content of electronic records that are on the system.
And the Open system means an environment in which system access is not controlled by persons who are responsible for the content of electronic records that are on the system.
My understanding from this is that i can't suggest Docusign or EchoSign anymore. Am i correct? And one more question , Do i need to create my very own esignature solution for this or is there any libraries or framework available?
