Information Hiding on Digital Documents by Adjustment of New-line Positions

摘要

In the usual information hiding applied to digital documents, secret messages are embedded in the layout information (e.g., the space between lines or characters) because character codes have no redundancy. This paper describes a new method for hiding information in plain text without using any layout information. It enables a secret message to be embedded as binary digits that are related to the number of characters in each line of the cover text.
