With the rapid development of Internet, safe covert communications in the network environment become an essential research direction. Steganography is a significant means that secret information is embedded into cover data imperceptibly for transmission, so that information cannot be easily aware by others. Text Steganography is low in redundancy and related to natural language rules these lead to limit manipulation of text, so they are both great challenges to conceal message in text properly and to detect such concealment. This paper presents a novel algorithm to hide a large amount of text in cover text without affecting the cover format, by using many types of pointers (which are characters can interpreter as invisible character, or as a part of cover. Pointers used as single pointer or set of pointer to represent new single pointer. The suggested algorithm can hide more than 40% of the cover size, which represent more than four times of the best known method used to hide text in text.
