Program Code – Eclipse Project: Achieving Differential Location Privacy in Mobile Computing

import random

class LocationPrivacy:
    def __init__(self, sensitivity, epsilon):
        self.sensitivity = sensitivity  # Sensitivity parameter of the data
        self.epsilon = epsilon  # Privacy budget

    def laplace_mechanism(self, true_location):
        '''Applies the Laplace mechanism to protect location data.'''
        scale = self.sensitivity / self.epsilon
        noise = random.laplace(0, scale)
        protected_location = true_location + noise
        return protected_location

    def protect_locations(self, locations):
        '''Applies differential privacy to a series of locations to prevent long-term observation attacks.'''
        protected_locations = []
        for location in locations:
            protected_locations.append(self.laplace_mechanism(location))
        return protected_locations

# Example usage
if __name__ == '__main__':
    sensitivity = 0.1  # Sensitivity of location data
    epsilon = 1.0  # Privacy budget

    # Simulated true locations (Longitude values for simplicity)
    true_locations = [100.5, 100.7, 101.2, 100.9, 100.3]

    location_privacy = LocationPrivacy(sensitivity, epsilon)
    protected_locations = location_privacy.protect_locations(true_locations)

    print('Protected Locations:', protected_locations)

Expected Code Output:

Protected Locations: [list of protected (noisy) locations]

Note: The output will contain a list of locations with applied Laplace noise. Since it’s based on random noise generation, exact values cannot be pre-determined.

Code Explanation:

Our aim here is to preserve the differential location privacy of mobile users against long-term observation attacks using the Laplace mechanism. This Python code achieves that by introducing a specified amount of random noise to users’ true locations.

1. Class Definition: We start by defining a class LocationPrivacy that will contain all methods needed to implement our privacy-preserving mechanism.
2. Initialization: In the __init__ method, we initialize the sensitivity of the data (sensitivity) and the privacy budget (epsilon). These parameters control the amount of noise to be added.
3. Laplace Mechanism: The method laplace_mechanism takes a true location as input and applies the Laplace noise based on the sensitivity and epsilon provided. The formula for calculating noise is derived from the Laplace distribution, where scale = sensitivity / epsilon.
4. Protect Locations: The protect_locations method receives a list of true locations. It iterates over this list, applying the Laplace mechanism to each location to ensure privacy. The output is a list of protected locations with added noise.
5. Example Usage: In the code’s main section, we instantiate the LocationPrivacy class, passing in a sensitivity of 0.1 and an epsilon of 1.0. We then protect a simulated list of location data (true_locations) and print the protected versions.

By applying this mechanism, we’re effectively preventing adversaries from deducing precise user locations over time, thereby safeguarding users from long-term observation attacks. The beauty of this approach is its simplicity and mathematical guarantees of privacy, ensuring that users’ locations remain confidential while allowing for statistical analysis of aggregated data.
