| Abstract | ||
| Several approaches and techniques have been proposed to make communication via the internet secure; one of these approaches is steganography. Steganography is the art and science of hiding communication, a steganographic system thus embeds hidden content in unremarkable cover media so as not to arouse an eavesdropper’s suspicion. In this research the proposed method is a public key steganography technique and it embeds a secret message in digital image with multi level of security. The proposed method uses Discrete Cosine Transform (DCT) to embed a secret message in Bit Mapped Image Format for Microsoft Windows (BMP) image with high invisibility and high correlation between cover-image and stego-image acceptable hiding data rate. | ||
