To resolve the trade-off between user privacy and data utility in location-based services by introducing an adaptive, quantum-inspired differential privacy framework tailored to diverse urban environments.
Designed a framework incorporating k-nearest-neighbor adaptive privacy budgeting, structured quantum-inspired noise generation, and a five-dimensional urban morphology descriptor.
Implemented a dual-task Hybrid Attention–Residual Deep Neural Network to jointly classify urban patterns and select optimal privacy mechanisms.
Evaluated performance across real-world mobility datasets against XGBoost, Tabular Transformers, and Graph Neural Networks using paired Wilcoxon signed-rank tests with Holm–Bonferroni correction across 156 comparisons.
The Hybrid DNN achieved a mean mechanism-classification accuracy of 97.35% ± 0.24 across ten seeds, with dual-task learning significantly improving accuracy by 0.33 percentage points (Wilcoxon p = 0.035).
Quantum-inspired Laplace mechanisms reduced mean absolute error by up to 33.19%, utility loss by up to 41.36%, privacy loss by up to 38.48%, and geo-indistinguishability error by up to 51.61% compared to classical baselines.
Quantum Anisotropic Gaussian reduced distortion metrics by 72% to 78%, while Quantum Exponential eliminated linkability risk; 133 of 156 cross-dataset comparisons (85.3%) showed statistically significant advantages.
