The network security is becoming more essential as the number of data being exchanged on the Internet increases.The data transmitted over the network may be detected, altered or hacked by the intruder.Therefore, privacy and data consistency are required to protect against unauthorized access and use.To overcome these problems, techniques such as Steganography and Cryptography can be adapted.This has resulted in an explosive development of the field of information hiding.This research work is a combination of Steganography and Cryptography, which provides a strong backbone for its security.In this research work, the secret message is encrypted before the actual embedding process starts.The main goal of this work is to hide a text of a secret message in the pixels of the image so that the Human Visual System is not able to distinguish between the original and the stego image.For this Image Steganography, We focus on the Least Significant Bit (LSB) technique in hiding messages in an image.This LSB technique embeds the bits of the message in the image and thus making it harder for unauthorized people to extract the original message encryption is used to protect the confidentiality of messages.Here, the sender sends the encrypted message by embedding using LSB technique with neural key.On the other end the receiver decrypts the message with the same key.The hidden message is encrypted using an encryption algorithm using secret key and hence it will be nearly impossible for the intruder to unhide the real secret message from the embedded cover file without knowing secret key.This present work focuses on enhancing the technique to secure data or message with authenticity and integrity
