Cepstrum-Based Watermarking for Secure Underwater Data Transmission
Muhammad Bilal
Abstract
This research introduces a novel methodology for underwater acoustic communication, utilizing the sounds found in the diverse marine ecosystem as a source of inspiration. This unique technique utilizes bio mimicry to replicate the complex acoustic patterns observed in the ocean, enabling the secure transmission of data in the presence of possible enemies or intrusive elements. In order to achieve mimicry communication with stealthy perspective in underwater acoustic channel, we utilize a novel technique referred to as cepstrum domain watermarking. The utilization of this technique allows for the discreet integration of information inside the complex arrangements of whale vocalizations, hence enhancing the level of confidentiality within our communication medium. During our investigation, we take into careful consideration the perceptual limits of human listeners as well as the constraints imposed by the data storage capacity of the underwater acoustic medium. The study’s empirical findings provide clear evidence of the theoretical and practical viability of our proposed approach for implementation in real-world commercial and military applications for covert communication in the vast oceans. This system proposes a unique and inconspicuous approach to address the urgent challenge of guaranteeing optimal security for underwater communication, with potential applications that encompass several industries.
