A Trajectory Privacy Protection Method Based on Random Sampling Differential Privacy
ISPRS International Journal of Geo-Information, 2021 With the popularity of location-aware devices (e.g., smart phones), a large number of trajectory data were collected. The trajectory dataset can be used in many fields including traffic monitoring, market analysis, city management, etc.

Truncated Laplace and Gaussian mechanisms of RDP
CoRR, 2023 The Laplace mechanism and the Gaussian mechanism are primary mechanisms in differential privacy, widely applicable to many scenarios involving numerical data. However, due to the infinite-range random variables they generate, the Laplace and Gaussian mechanisms may return values that are semantically impossible, such as negative numbers.

Non-equal-width histogram publishing method based on differential privacy
网络与信息安全学报, 2020 Existing histogram publishing technology based on differential privacy may show phenomenon of "retracting" and "zero bucket" when histogram is used to reflect the real distribution characteristics of data, and "too gentle" in the case of large data ...

Analysis of Particulate Systems with Numerical Inverse Laplace Transform [PDF]
Journal of Applied and Computational Mechanics, 2023 The technique of numerical inversion of the Laplace transform is applied to solve the population balance equation (PBE). The model considers the dispersed phase systems in which nucleation and heterogeneous condensation are present. The studied phenomena

The Laplace Method for Energy Eigenvalue Problems in Quantum Mechanics
Quantum Reports, 2023 Quantum mechanics has about a dozen exactly solvable potentials. Normally, the time-independent Schrödinger equation for them is solved by using a generalized series solution for the bound states (using the Fröbenius method) and then an analytic continuation for the continuum states (if present).

Optimality of the Laplace Mechanism in Differential Privacy
CoRR, 2015 In the highly interconnected realm of Internet of Things, exchange of sensitive information raises severe privacy concerns. The Laplace mechanism -- adding Laplace-distributed artificial noise to sensitive data -- is one of the widely used methods of providing privacy guarantees within the framework of differential privacy.
