Digital signatures provide an electronic means of verifying the authenticity
of signatures that are attached to drawing files.
Overview of Drawings with Digital Signatures
A digital signature identifies an individual or an organization through a digital
ID (certificate), and enables you to validate the file. Validating a file is especially
important when you are working on collaborative projects or transmitting
files over the Internet. You can validate a digital signature in either the program
or Windows Explorer.
Using the digital signatures feature, you can obtain the following information
about signed files:
■ Whether the file was changed since signed.
■ Whether the signers are who they claim to be.
■ Whether the signers can be traced (thus preventing forgery).
A digital signature is determined to be invalid for the following reasons:
■ The file was corrupted when the digital signature was attached.
■ The file was corrupted in transit.
■ The digital ID is no longer valid.
