“…A lightweight SE using ChaCha20 algorithm was applied for securing the videos by only encrypting key points detected through the FAST feature detector [24]. Another research proposed a solution to protect sensitive videos during streaming [25], in which chaotic-based encryption was applied and for that purpose 1-D and 2-D models were utilised. The confusion and diffusion properties of that logistic map and Arnold's cat map-based algorithm were good.…”

The purpose of smart surveillance systems for automatic detection of road traffic accidents is to quickly respond to minimize human and financial losses in smart cities. However, along with the self-evident benefits of surveillance applications, privacy protection remains crucial under any circumstances. Hence, to ensure the privacy of sensitive data, European General Data Protection Regulation (EU-GDPR) has come into force. EU-GDPR suggests data minimisation and data protection by design for data collection and storage. Therefore, for a privacy-aware surveillance system, this paper targets the identification of two areas of concern: (1) detection of road traffic events (accidents), and (2) privacy preserved video summarization for the detected events in the surveillance videos. The focus of this research is to categorise the traffic events for summarization of the video content, therefore, a state-of-the-art object detection algorithm, i.e., You Only Look Once (YOLOv5), has been employed. YOLOv5 is trained using a customised synthetic dataset of 600 annotated accident and non-accident video frames. Privacy preservation is achieved in two steps, firstly, a synthetic dataset is used for training and validation purposes, while, testing is performed on real-time data with an accuracy from 55% to 85%. Secondly, the real-time summarized videos (reduced video duration to 42.97% on average) are extracted and stored in an encrypted format to avoid un-trusted access to sensitive event-based data. Fernet, a symmetric encryption algorithm is applied to the summarized videos along with Diffie–Hellman (DH) key exchange algorithm and SHA256 hash algorithm. The encryption key is deleted immediately after the encryption process, and the decryption key is generated at the system of authorised stakeholders, which prevents the key from a man-in-the-middle (MITM) attack.

As a new energy‐supply service solution to address massive, distributed energy access to the power system, a virtual power plant has higher transmission reliability and real‐time communication requirements. To achieve collaborative optimisation, distributed load and energy resources must be aggregated using new information and communication technology. This study analyses underlying communication technologies for virtual power plant interaction from the perspective of standardisation, efficiency, reliability, and security, summarises the application of blockchain, cloud‐edge collaboration, machine learning, and other new information and communication technologies in virtual power plant energy trading, interaction, and scheduling, and proposes ideas for addressing shortcomings in interaction. To improve virtual power plant interaction, performance parameter mapping between communication and business technology, and multilevel virtual power plant interaction technology are proposed.

“…After acquiring the video stream from the webcam, the video codec encoder is used to compress the video data. The stream bits are encrypted using the chaotic encryption method [26] [27]. Then the DVB-T standard is applied to code, interleave, and map the stream data to QPSK, 16-QAM, and 64-QAM modulation, followed by error correction codes and the shuffling of the bit positions in the blocks.…”

Software-Defined Ultrasonic Communication System With OFDM for Secure Video Monitoring

Ultrasonic communication is a desirable method for information transfer through solid channels such as metallic bars, plates, or pipes by overcoming the physical barriers that prevent conventional wired or radiofrequency transmission. In this paper, we investigate the architecture of a reconfigurable software-defined ultrasonic communication (SDUC) platform that can make use of the complete channel bandwidth for real-time video transmission through a highly reverberant solid channel. Reverberations in solid channels are complex and generated by surface wave, lamb wave, longitudinal wave, shear wave, reflection, refraction, dispersion, mode conversion, and scattering phenomena. To explore the multipath and fading effects on bitrate, experimental studies were performed using an aluminum rectangular bar (ARB) of 25, 40, and 50 cm channel length. We investigated the feasibility of utilizing orthogonal frequency-division multiplexing (OFDM) combined with quadrature amplitude modulations (QAM) for peak bitrate performance. Design strategies and guidelines have been established for the best solutions to combat intersymbol interference caused by the severe reverberation inherent to ultrasonic solid channels. A practical solution for video transmission, adhering to the Digital Video Broadcasting Terrestrial (DVB-T) standard, is also examined for video streaming transmission of 240p, 480p, and 720p resolutions at 20 frames per second across an ARB channel. For experimental studies and performance evaluation, we designed a highperformance reconfigurable system-on-chip (SoC) SDUC platform for video transmission and bit error rate (BER) assessment. Through experimental studies for ultrasonic channel analysis, we achieved a peak video transmission rate of 1074 kbps with 3.3×10 -4 BER despite reverberation, the multipath effect, and signal fading within the ARB channel.INDEX TERMS Communication channels, Ultrasonic transducers, OFDM, Software radio, Multipath channels, Digital video broadcasting I. INTRODUCTIONUltrasonic communication is a viable method for transmitting information through solid communication channels, such as metal pipes, rectangular bars, or plates [1] [2][4]. This method overcomes the physical barrier that prevents conventional wired or wireless communication. For example, nuclear facilities are partitioned into different blocks for isolation and safety purposes. Each block is hermetically sealed by a thick reinforced concrete wall with an existing in-place metal infrastructure, such as pipes. Consequently, ultrasound is a promising technique for communication by utilizing embedded metal structures. Also, pipelines and chemical containers have metal structures that can be used as channels for ultrasonic communications. An 800-bps communication system [5] using multitone frequency-shift keying (FSK) was designed using steel corner posts from shipping containers as the communication channel. In our earlier work [2] [3], only a 2-Kbps bitrate with a bit error rate (BER) of 1×10 -3 was achieved for image transm...
