Steganography is the art of hiding data within data where it is an encryption technique that can be used along with cryptography as an extra-secure technique to secure data. The security of information can be prospered by using encryption and steganography. In cryptography, at first the original form of data is encrypted into another form and then it is transferred. The proposed system improves the security system by combining these two techniques. In this system, the encrypted data is embedded in a BMP/JPEG image file and intends for data confidentiality, data authentication and data integrity. Data is encrypted with RC4 encryption algorithm and then embedded the encrypted data in the BMP/JPEG image file using LSB steganographic method where the primary goal of this system could be attained.
