Abstract - Message Security - Hiding a secret message when sending it to an authorized user without any attack is the most difficult task. Steganography is one such method for sending a secret text across the secure communication medium and protect the information throughout transmission. Background: Communication is widely carried out using network through email, sms, etc., but a sending of secret text through insecure channel is a big challenge. The limitations of text being sent via the communication medium and overhead involves are in terms of time, payload, etc., In this paper, text steganography technique are used to protect the secret text using Unicode characters. The similarities of glyphs provide same as alphabetic characters and the overall increase of hiding capacity. Result: The results prove that secret data, embedded in the cover text using Unicode characters preserves secrecy. The embedding and extraction done efficiently. The secret text (stego-text) is again embedded under a cover image it’s provides double security to the secret text. Conclusion, the proposed technique successfully secure the secret data and achieves the high payload capacity, the text length are unlimited.
