When a user signs a PDF digitally, a unique identifier is created, linking the signer to the document. This process not only confirms the identity of the signer but also ensures that the document has not been altered after signing. Digital signatures are widely accepted in various sectors, including legal, finance, and healthcare, making them a vital tool for modern business practices.
