In another post we introduced the topic of digital signatures by talking about secure websites. We mentioned that web browsers include built-in lists of trusted certificate providers to increase security. That doesn’t mean that certificates issued by other providers are not as secure. All it means is that a reliable third party somehow validated the identity of the person or organization requesting the certificate.
The information technology departments of companies often create their own certificates for use internally because they trust themselves and can add themselves to the trusted list in their employees’ web browsers. But if they tried to use those self-generated certificates on the public Internet then their customers’ web browsers would display a scary “not trusted” message. Obtaining certificates from a trusted third party provider that verifies identity in some way gives the public more confidence in the company.
Similarly, the State of California approves electronic notarization solution providers if they comply with the technical specifications of the rules and standards that govern electronic notarization processes and procedures in California.
