In this fast paced world, electronic communication has become one of the significant media that connects different parts of the world. As a result, security has become an issue where it is increasingly susceptible to eavesdropping and malicious interventions. The need to solve this problem has led to the development of steganography schemes. Steganography which is different from cryptography is a tool for privacy and security. Steganography is a powerful technique that provides a high level of security, particularly when it is combined with encryption. Cryptography involves converting a message text into an unreadable cipher while steganography works by hiding messages in inconspicuous objects that are then sent to the intended recipient. Digital Watermarking is a technology which provides authentication and copywrite protection for multimedia contents over the internet and is basically used for intellectual property protection. In this project we propose an advanced system of encrypting data that combines the features of cryptography, digital watermarking and steganography along with multimedia data hiding. Thus even if steganography fails, the message cannot be recovered because a cryptography technique is used as well. This system provides authentication, imperceptibility, robustness and security with high PSNR (Peak Signal to Noise Ratio) value and less MSE (Mean Square Error) value. © Research India Publications.
