Abstract
This article introduces a novel approach to address the security challenges of chipless tag systems in the context of Internet of Things (IoT) applications. The proposed technique focuses on preventing tag cloning by leveraging the inherent natural randomness in the fabrication process. A groundbreaking aspect of this research is the utilization of an affordable and portable Multiple Input Multiple Output (MIMO) antenna system in real-world scenarios to detect counterfeit tags. The study begins by validating the precision of the MIMO system, establishing its effectiveness compared to Vector Network Analyzer (VNA) equipment. Additionally, the clone detection system is thoroughly evaluated for accuracy, and improvements are introduced through various Machine Learning (ML) models. The ML techniques used were able to detect clones with 99.78% accuracy, outperforming VNA equipment. This research represents a significant advancement in chipless tag security for IoT applications, offering a cost-effective and efficient solution to the pressing security issue of tag cloning.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
