Abstract

See full text

A method and apparatus for providing media-independent security for a document is provided. In one embodiment, a method includes inputting image data corresponding to an interpretable image displayable by a display device in an interpretable format to be readily interpretable by a user; inputting security data corresponding to security information; creating, in a first medium, a document including a substantive portion; and a security portion inseparable from the substantive portion. The method further includes transferring the document into a second medium; decoding symbols into binary security data representing the security information; and outputting the binary security data in a format retrievable to be interpretable as the security information.
