摘要：Steganography can be used for hiding the secret message within a larger one in such a way that others can’t discern the presence or contents of hidden message. The Steganography algorithms employ multimedia as the medium to ensure hidden exchange of information between multiple contenders and to protect the data from unauthorized access. Text documents can be watermarked by patterning the inter word spaces. Steganography with watermarking adds additional security to the document and it provides high levels of exploitation of novel concepts of word classification and inter-word space statistics. The text steganography algorithms are based on modification of word style, spaces etc. Here, the nonlinear word positions of data in the document are targeted with insignificant modifications and by grouping into segments and their classification using word class information where the amount of information is dependent on requirement. This information is encoded by modifying some statistics of inter-word spaces of segments belonging to same class.
