PDF security refers to the various measures put in place to protect the contents of the PDF file from unauthorized access, modification, copying, or printing. These security features help control who can view, edit, or perform specific actions on the document.

Some common security measures in a PDF include:

Password Protection: This involves setting a password that must be entered to open the PDF file. Without the correct password, the content of the PDF remains inaccessible.

Encryption: PDFs can be encrypted, which means the data within the file is encoded using algorithms, making it unreadable without the decryption key. Encryption helps safeguard the contents from unauthorized viewing or tampering.

Permission Settings: PDFs can have specific permissions set, such as restricting printing, copying text or images, modifying the content, or adding annotations. These permissions allow the document owner to control what actions can be performed on the PDF by different users.

Digital Signatures: PDFs can be digitally signed to confirm the authenticity of the document and verify the identity of the signer. Digital signatures help ensure the integrity of the content and confirm that it has not been altered since it was signed.
