中文摘要 | 本論文提出適用於軍事地圖與衛星影像疊合之藏密技術。本技術利用改良型簡單 LSB取代技術將二值化地圖隱藏在衛星影像的最低位元平面,除保有簡單LSB取代技術的實作簡單及藏密量大等優點外,還可同時抵抗統計式分析之攻擊,具有比簡單LSB取代技術更安全的特性。因本藏密技術具有上述之優點,可在低頻寛及低運算能力設備上輕易達到影像與圖層疊合的效果。實驗結果顯示,本文所提的藏密技術具有良好的不可見性,並可有效抵抗卡方攻擊及RS偵測,非常適合數位化戰場的實務應用。 |
英文摘要 | In this paper, we present a steganographic method for overlaying a military map on a satellite image. The proposed method uses a modified simple LSB replacement technique to embed a binary map in the least significant bit plane of a satellite image. The proposed method not only can maintain the properties of easy implementation and high capacity of the simple LSB replacement techniques, but also can resist the statistical attacks to gain the property of better security. Due to the above superiority, the proposed method can easily overlay a binary map on a satellite image on low-bandwidth and low-computational-power devices. Experimental results show that the proposed method have good imperceptibility and can resist Chi-square attack and RS steganalysis, and is practical for applications of digital battle fields. |
