N2 - Communications via Microsoft Power Point (PPT for short) documents are commonplace, so it is crucial to take advantage of PPT documents for information security and digital forensics. In this study, we propose a new method of text steganography, called MIMIC-PPT, which combines text mimicking technique with characteristics of PPT documents. Firstly, a dictionary and some sentence templates are automatically created by parsing the body text of a PPT document. Then, cryptographic information is converted into innocuous sentences by using the dictionary and the sentence templates. Finally, the sentences are written into the note pages of the PPT document. WithMIMIC-PPT, there is no need for the communication parties to share the dictionary and sentence templates while the efficiency and security are greatly improved.
