Crypto Deep Ring Topology Firewall in Sensitive Data Transmission and Retrieval in Cloud
IET Information Security, Volume 2024, Issue 1, 2024.The data transmission and data retrieval process from the cloud is a critical issue because of cyber‐attacks. The data in the cloud is highly vulnerable and may fall prey to hackers. The hackers tend to attack the data in the public network, deteriorating the range of confidentiality and the authentication of the data.

A Multimodal Low Complexity Neural Network Approach for Emotion Recognition
Human Behavior and Emerging Technologies, Volume 2024, Issue 1, 2024.This paper introduces a neural network‐based model designed for classifying emotional states by leveraging multimodal physiological signals. The model utilizes data from the AMIGOS and SEED‐V databases. The AMIGOS database integrates inputs from electroencephalogram (EEG), electrocardiogram (ECG), and galvanic skin response (GSR) to analyze emotional ...
