Abstract

Deepfake content poses a significant challenge to cybersecurity and media integrity, exploiting advanced AI techniques to generate hyper-realistic yet deceptive visuals. Existing detection methods often lack scalability and precision, particularly in real-time applications. This study presents a novel graded-index photonic crystal fiber (GI-PCF)–based surface plasmon resonance (SPR) sensor, offering an innovative solution for advanced deepfake detection and media authentication. By integrating a graded-index core with nanostructured plasmonic layers, the sensor achieves superior light confinement, optimized refractive index sensitivity, and enhanced detection precision. Experimental results demonstrate key achievements, including a figure of merit (FOM) of 450 RIU⁻¹, sensitivity of 12,500 nm/RIU, and detection accuracy of 98.7%. These advancements highlight the sensor’s capability to detect minute optical anomalies in tampered media, establishing a scalable and robust framework for real-time media verification and deepfake mitigation.

用于先进深度伪造检测和实时媒体完整性分析的创新型分级指数pcf型SPR传感器

深度造假内容利用先进的人工智能技术生成超现实但具有欺骗性的视觉效果，对网络安全和媒体完整性构成了重大挑战。现有的检测方法往往缺乏可扩展性和精度，特别是在实时应用中。本研究提出了一种新型的基于梯度折射率光子晶体光纤（GI-PCF）的表面等离子体共振（SPR）传感器，为先进的深度假检测和介质认证提供了一种创新的解决方案。通过将渐变折射率核心与纳米结构等离子体层集成，该传感器实现了优越的光约束，优化了折射率灵敏度，提高了检测精度。实验结果证明了关键成果，包括450 RIU−1的优值（FOM）， 12,500 nm/RIU的灵敏度和98.7%的检测精度。这些进步突出了传感器检测篡改介质中微小光学异常的能力，为实时介质验证和深度伪造缓解建立了可扩展且强大的框架。

期刊介绍： Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons. Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
