Secure PDF - PDF Encryption

Samsung Secure Data allows you to encrypt a PDF document to protect its contents from unauthorized access. Encryption
applies to all strings and streams (Scanned Images) in the document's PDF file, but not to other object types such as
integers and Boolean values, which are used primarily to convey information about the document's structure rather than
its content. Leaving these values unencrypted allows random access to the objects within a document, whereas
encrypting the strings and streams protects the document's substantive contents. The PDF encryption process follows this
path:
1. The AES algorithm is used for data encryption
2. Key data is generated by using the Owner Password and User Password from the hash function.
The scope of this encryption includes all data streams, all creation data, all of the creator information, and all of the
producer information.
Example of the PDF encryption workflow:
