Therefore, to achieve truly secure and reliable paperless management, these security issues must be solved.

MeSign digital signature and encryption solutions for documents provide a complete solution which perfectly overcome the two major security issues on trust and security that exist in all industries in the paperless transformation process. MeSign Technology has proposed specific solutions for the typical eight major industries, which can effectively help users in these industries to smoothly implement the comprehensive paperless business process transformation and it perfectly achieves a secure document-based paperless management and mobile management.

Document Digital Signature and Encryption for Government

Government agencies issue a large number of certificates and documents every day, issue government announcements, send notifications of the e-government results to citizens, and the internal documents signature etc. They have begun to shift to paperless, but the problem is how to ensure that these electronic documents are really issued by government agency, have not impersonated, have not tampered. At present, the only feasible technical solution is to digitally sign the PDF document with timestamp and send them to users by encrypted email.

MeSign not only provides digital signature automation solution that can help the PDF documents that generated by the internal business systems of government departments to make the trusted digital signature with only one click, but also provides email signature and encryption automation solution to help the business systems of government departments to send the signed PDF document by encrypted email to citizen, and completely make all electronic files with reliable digital signature without counterfeiting and make the delivery of all electronic files more secure .

As shown in the below diagram, citizens and enterprises need to fill in forms online when they handle the services on the e-government service system. After completing the forms, the citizens can sign by hand on the business system, and the enterprises sign with their own USB Key certificate and submit in the e-government system. After the processing is completed, the e-government system calls the cloud MeSign eSigning Service system or locally calls the MeSign e-Signature System to sign the PDF file with Adobe trusted certificate. For services that do not require the user to fill in the form (such as announcement or notice), the PDF file generated on the e-government system can be directly called the MeSign eSigning Service to complete the PDF signature.

It is recommended to encrypt all important government affairs documents. System just need to call MeSign public key certificate database (CerDB) to obtain the user's encryption certificate to encrypt the PDF file, the user can seamlessly view the encrypted PDF file using Adobe Reader. The e-government system sends encrypted emails to users using the user's encryption certificate, ensuring the secure and reliable delivery of various user confidential documents. Users only need to use MeSign App to decrypt and read the documents.

This solution has four advantages to ensure that all important documents of the government departments are trusted paperless and are encrypted in delivery:

1. From the user's online application to the delivery of document, the whole process is trusted paperless and are automatically encrypted in delivery. All documents have digital signatures to prove the true identity of the issuer of the document, preventing the government documents from being counterfeited.
2. Not only the government documents sent to users have Adobe global trusted digital signatures to prove their identity, but also the government documents can be encrypted with user certificate, and only the designated users can open and read it.
3. This solution not only provide PDF file signing and encryption, but also it provides the function to deliver the PDF files through encrypted email to ensure that the PDF file will not be easily stolen and tampered with during the delivery process.
4. All signed PDF files can be stored by encrypted archives, and all files are time stamped to ensure that once all files are signed and archived, no one can modify these files. Otherwise, the signature and time stamp information will be invalidated, effectively ensuring the long-term security and credibility of the document. The timestamp signature is very useful for subsequent file inspections and audits and can ensure that the document signing behavior and the signing time is authentic, undeniable and cannot be tampered with.
