In all over the world maintain the security of the secret data has been a great challenge. One way to do this is to encrypt the message before sending it. Encrypted messages sending frequently through a communication channel like Internet, draws the attention of third parties, hackers and crackers, perhaps causing attempts to break and reveal the original messages. Steganography is an emerging area which is used for secured data transmission over any public media. Steganography is of Greek origin and means "Covered or hidden writing". Considerable amount of work has been carried out by different researchers on steganography. In this paper, a steganographic model combining the features of both text and image based steganography technique for communicating information more securely between two locations is proposed. The authors incorporated the idea of secret key for authentication at both ends in order to achieve high level of security. As a further improvement of security level, the information has been encoded through SSCE values and embedded into the cover text using the proposed text steganography method to form the stego text. This encoding technique has been used at both ends in order to achieve high level of security.. Next the stego text has been embedded through PMM method into the cover image to form the stego image. At the receiver side different reverse operation has been carried out to get back the original information.
