Real-time images are challenging to process with conventional technologies because they include a diversity of information with significant prolixity, high correlation among neighboring pixels, and high uncertainty due to sensor noise and environmental conditions. Therefore, the present work focuses on the secured transmission of real-time satellite images with a high Signal-to-Noise ratio. In this work, we have developed a novel hybrid encryption method that combines a six-dimensional (6D) hyper-chaotic system with the BB84 quantum key distribution (QKD) protocol for secure and efficient image transmission. The hyper-chaotic system enhances pixel scrambling and diffusion, reducing correlations in the image data, while BB84 ensures secure key exchange during transmission over Free Space Optics (FSO) channels. The integration of a 6D hyper-chaotic system with BB84 QKD protocol is capable of transmitting multichannel information in a single secured channel. The proposed technique is corroborated using a set of satellite images, as satellite images possess highly correlated information. In the proposed model, the original satellite images are taken for Gunupur, Odisha during the period of November 22, 2023, to January 23, 2024. These images’ information is confused by the hyper-chaotic system. Then, the permuted images are diffused to generate the scrambled image using the BB84 protocol. On the receiver side, the same information is recovered with reduced information loss using the proposed receiver module, which consists of an optical hard limiter followed by a low pass filter.

For these purposes, the practice of integrating data-driven models in assessing and predicting lake WQ has received wider application. Nevertheless, the optimal performance of the data-driven models depends on the model hyperparameters and hyperparameter optimization techniques have crucial role in this regard. Therefore, the research aimed to assess the impact of various optimization techniques on these prediction models in order to predict the lake WQ. For the purposes of reliable lake water state assessment, this study presents a comprehensive analysis of lake WQ prediction, integrating sophisticated Root Mean Squared (RMS)-Water Quality Index (WQI) model with eight machine learning algorithms (ML), two Artificial Intelligence (AI) techniques, and five optimization methods. Comparing five optimization methods—Grid Search (GS), Random Search (RS), Bayesian Optimization (BO), Optuna (OPT), and Tree-based Pipeline Optimization Tool (TPOT)—revealed their significant influence on model performance and computational efficiency. Based on the analysis, random forest (RF) integrated with TPOT consistently demonstrated robust performance compared to other models, achieving an impressive R² value of 0.94 during training (Root mean squared error-RMSE= 0.85, Mean squared error-MSE= 0.73, Mean absolute error-MAE= 0.48, and Percentage of absolute bias error-PABE= 2.35), testing (RMSE= 0.43, MSE= 0.18, MAE= 0.15, and PABE= 0.19), and validation (RMSE= 0.96, MSE= 0.96, MAE= 0.823, and PABE= 1.08), indicating its precision in predicting lake WQ. The results reveal that TPOT and OPT show remarkable effectiveness in optimizing the hyperparameter space to enhance model accuracy across various ML/AI model combinations.
