PLA supports electronic signatures for entire documents and parts of the document. A document signature protects the entire document from modification. A document part signature is capable of protecting certain parts of the documents (e.g. you might want to sign and thereby protect the raw data).
Several policies allow the fine-tuning of electronic signatures according to your company standards.
Digital signatures are signatures that follow cryptographic standards. PLA 3.0 automatically applies a digital signature to every document. When you open, export or import the document, PLA validates the digital signature to ensure the document's integrity.
One of the benefits of this approach: you can transfer your documents and templates even with unsafe media (such as E-mail) and don't have to worry about it. PLA ensures the integrity of the information on its own.
