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 study proposes a novel text steganography method which takes into account the Font Types. This new method depends on the Similarity of English Font Types; we called it (SEFT) technique. It works by replace font by more similar fonts. The secret message was encoded and embedded as similar fonts in capital Letters of cover document. Proposed text steganography method can works in different cover documents of different font types. The size of cover and stego document was increased about 0.766% from original size. The capacity of this method is very high and the secret message was inconspicuous to an adversary.
