Abstract:
Steganography is the art and science of hidinginformation.The goal of steganography is to avoid drawing suspicion to the transmission of a hidden message. The success of steganography depends on the secrecy of the cover carrier.Once the steganographic carrier is disclosed then the security depends on the robustness of the algorithm and the cryptographic methods used. Therefore, to maintain secrecy either we need to make the carrier more robust against steganalysis or discover new and better carriers. This paper discusses a new steganography technique for palette based images. Secret message is encrypted using public key cryptography before hiding. The bits of encrypted message will be hidden inside the stretched palette of image.

翻譯摘要:
資訊隱藏是在隱藏資訊上的技術與科學。資訊隱藏的目標是為了避免被懷疑傳送隱藏的訊息。
成功的資訊隱藏依靠保密來保護傳送人。一旦資訊隱藏的傳送者洩漏資訊，也必須依靠強大的演算法和使用密碼的方法。因此，為了維護任一個秘密，我們要準備傳送者及更多強韌的的防護隱藏分析或尋找新的和更好的傳送者(個人覺得式傳送方式)。這個論文討論了新的在調色板為基礎的影像上之資料隱藏技術。再隱藏前，秘密訊息的編譯使用公開的密碼鑰匙。 這個用密碼編譯的訊息會隱藏在影像的調色盤結構裡面。
