Special Issue Information

Dear Colleagues,

In recent years, the field of sensor security systems has seen significant advancements, driven by technological innovations, increasing demand for robust security solutions, enhanced wireless connectivity, improved energy efficiency, and so on. The integration of multiple sensor types enables comprehensive threat detection, enhancing reliability and effectiveness.

Despite these advancements, several challenges remain. Ensuring cybersecurity to protect sensors from attacks is crucial, especially as sensor interconnectivity grows. Continued research is essential to address these issues and further improve sensor security systems.

This Special Issue focuses on novel advances and challenges in this field. Our goal is to bring together researchers, industry, and companies operating in related fields to share recent discoveries, new ideas, and cutting-edge accomplishments.

Topics of interest include, but are not limited to, the following:

  • Emerging Technologies in Sensor Security;
  • Integration of Blockchain in Sensor Security;
  • Advanced Encryption Techniques for Sensor Data;
  • Machine Learning/Artificial Intelligence and Sensor Security;
  • Challenges in Securing IoT Devices;
  • Cybersecurity Issues, Threats, and Vulnerabilities in Sensor Systems;
  • Automotive System Security;
  • Security in Healthcare Sensor Systems;
  • Security in Smart Home.

Steganography serves a crucial role in secure communications by concealing information within non-suspicious media, yet traditional methods often lack resilience and efficiency. Distributed steganography, which involves fragmenting messages across multiple containers using secret sharing schemes, offers improved security but increases complexity. This paper introduces a novel two-phase embedding algorithm that mitigates these issues, enhancing both security and practicality. Initially, the secret message is divided into shares using Shamir’s Secret Sharing and embedded into distinct media containers via pseudo-random LSB paths determined by a unique internal stego key. Subsequently, this internal key is further divided and embedded using a shared stego key known only to the sender and receiver, adding an additional security layer. The algorithm effectively reduces key management complexity while enhancing resilience against sophisticated steganalytic attacks. Evaluation metrics, including Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index Measure (SSIM), demonstrate that stego images maintain high quality even when embedding up to 0.95 bits per pixel (bpp). Additionally, robustness tests with StegoExpose and Aletheia confirm the algorithm’s stealthiness, as no detections are made by these advanced steganalysis tools. This research offers a secure and efficient advancement in distributed steganography, facilitating resilient information concealment in sophisticated communication environments. Full article

Biometrics-based authentication mechanisms can address the built-in weakness of conventional password or token-based authentication in identifying genuine users. However, 2D-based fingerprint biometrics authentication faces the problem of sensor spoofing attacks. In addition, most 2D fingerprint sensors are contact-based, which can boost the spread of deadly diseases such as the COVID-19 virus. Three-dimensional fingerprint-based recognition is the emerging technology that can effectively address the above issues. A 3D fingerprint is captured contactlessly and can be represented by a 3D point cloud, which is strong against sensor spoofing attacks. To apply conventional 2D fingerprint recognition methods to 3D fingerprints, the 3D point cloud needs to be converted into a 2D gray-scale image. However, the contrast of the generated image is often not of good quality for direct matching. In this work, we propose an image segmentation approach using the deep learning U-Net to enhance the fingerprint contrast. The enhanced fingerprint images are then used for conventional fingerprint recognition. By applying the proposed method, the fingerprint recognition Equal Error Rate (EER) in experiment A and B improved from 41.32% and 41.97% to 13.96 and 12.49%, respectively, over the public dataset.
