AI总结:

针对传统隐写术固定单一载体、无法自适应的问题,本文提出基于跨模态推理(CMR)引擎的智能载体分配框架,通过评估多模态载体适配性分配秘密比特流,提升系统安全性与保密性。

摘要:

在存在多种媒体类型的当今数字世界中,隐写术这一秘密通信技术面临诸多挑战。传统方法通常固定且仅适用于单一载体媒体类型,因此无法很好地适配现有各类媒体。该系统因无法自适应而不会将数据发送至“弱”或易检测载体,导致整体安全性和保密性降低。本文提出一种基于跨模态推理(CMR)引擎的新型智能载体分配框架,该引擎分析图像、音频和文本等多种载体的隐写适配性,利用熵、信号复杂度和词汇丰富度等关键指标为每种模态生成单一可靠性评分。框架基于这些评分公平智能地分配秘密比特流,将更多数据分配给更强、更复杂的载体。这种自适应分配策略使系统尽可能难以被发现,并增强对隐写分析的抵抗力。我们证明,与静态、非自适应多模态技术相比,这种基于推理的方法更安全,在数据保护方面更优越,有助于构建更强大、更智能的秘密通信系统。

英文摘要:

In today's digital world, which has many different types of media, steganography, the art of secret communication, has a lot of problems to deal with. Traditional methods are often fixed and only work with one type of carrier media. This means they don't work well with all the different types of media that are out there. This system doesn't send data to "weak" or easily detectable carriers because it can't adapt. This makes the system less safe and less secret in general. This paper proposes a novel Intelligent Carrier Allocation framework founded on a Cross-Modal Reasoning (CMR) Engine. This engine looks at a wide range of carriers, such as images, audio, and text, to see if they are good for steganography. It uses important measurements like entropy, signal complexity, and vocabulary richness to come up with a single reliability score for each modality. The framework uses these scores to fairly and intelligently share the secret bitstream, giving more data to carriers that are thought to be stronger and more complex. This adaptive allocation strategy makes the system as hard to find as possible and as strong as possible against steganalysis. We demonstrate that this reasoning-based approach is more secure and superior in data protection compared to static, non-adaptive multimodal techniques. This makes it possible to build stronger and smarter secret communication systems.
