PDF security


I have come across with one requirement where I need to give facility to the end user of the website to digitally sign their scanned PDF document and upload it. Further at receiver end, authentication check of the document can be done to verify if document is tempered.

Can anyone pl suggest how this can be achieved using ASPOSE PDF .net API. I am writting website in .NET MVC using c#.

Thanks in advance for help.
