PDF Security

PDF security refers to measures taken to protect PDF files from unauthorized access and manipulation. It includes password protection, which restricts who can open or edit the document, and encryption, which scrambles the content to prevent theft. Permissions can also limit actions like printing or copying. These security features ensure that sensitive information remains confidential and that the document's integrity is maintained. Overall, PDF security provides a way to safeguard documents in an increasingly digital environment, where data breaches and unauthorized access are concerns.
