What is the role of a Certification Authority in document processing?

The role of a Certification Authority (CA) in document processing is to provide trusted digital certificates. These certificates serve as a digital form of identification that verifies the identity of individuals or organizations using electronic communications. By issuing these certificates, a CA helps to ensure the integrity and authenticity of digital signatures and transactions, thereby enhancing trust in electronic document processing and communications.

Digital certificates issued by a CA are essential for establishing secure connections over the internet, particularly in systems that require confidentiality and authentication, such as e-commerce and electronic notary services. They provide a way to verify that a public key belongs to the individual or entity that it claims to represent, ensuring that communications are secure and can be trusted. This role is critical in preventing fraud and ensuring the legality of digital transactions and documents.
