An Algorithm of Text Information Hiding Based on Font
Bing Wang · Computer Technology and Development · 2006
An improved algorithm of text information hiding based on font is proposed in this paper.First of all,the characters in the secret text are changed into ACSII codes.Secondly,ASCII codes are changed into 16 bit-binary codes.Then,the higher 8 bits and lower 8 bits in 16-binary codes are transformed into decimal codes,which are encrypted by RSA algorithm.Finally,switch the encrypted decimal to 16-bit binary again,and hide them into the cover text with faking random replacing rule.Chose two kinds of similar font,if the code is 1,the font of character keeps the original style,and if the code is 0,the font of character switches to other one,which is quite similar to the original one.As the result,the algorithm is safer than just using characteristic-based information hiding algorithm.
