Privacy-Preserving Location-based Query with Encrypted Data

Problem Definition

Problem Description: With the increasing popularity of location-based services (LBS) and the widespread use of smartphones, the issue of privacy in LBS has become a growing concern. Many users are hesitant to use LBS due to the lack of privacy protection for their location data. The current solutions for privacy preservation in LBS are either inefficient or do not provide adequate protection. One common problem is that existing systems do not efficiently handle location-based queries over encrypted data. This leads to high query latency and can potentially reveal sensitive information about the user's location.

Additionally, the lack of privacy-preserving index structures in LBS queries can further compromise the user's privacy. Therefore, there is a need for a more efficient and privacy-preserving solution for location-based queries over outsourced encrypted data. The proposed project, EPLQ: Efficient Privacy-Preserving Location-based Query over Outsourced Encrypted Data, aims to address these challenges by providing a secure and efficient way to query point of interest information while protecting the user's location privacy. By implementing EPLQ, users can perform location-based queries with reduced latency and improved privacy protection. This project will enable mobile LBS users to securely access point of interest data within a given distance without compromising their location privacy.

Proposed Work

The project titled "EPLQ: Efficient Privacy-Preserving Location-based Query over Outsourced Encrypted Data" addresses the issue of privacy concerns in Location Based Services (LBS) by proposing a solution that ensures efficient and secure location-based queries. The implementation involves detecting the position of a user within a specified privacy range using encryption, and then utilizing a privacy-preserving tree index structure to reduce query latency. The use of Opto-Diac & Triac Based Power Switching, Introduction to ASP, Relay Driver (Auto Electro Switching) using ULN-20, and JAVA modules enables the development of this privacy-enhancing solution. Particularly focusing on the Android platform, which is widely used in mobile-based applications, the project aims to improve the privacy of LBS users while providing information about Points of Interest (POIs) in their vicinity. By incorporating these technologies and methodologies, the proposed EPLQ system offers a promising approach to enhancing the privacy and efficiency of location-based queries for mobile LBS users.

Application Area for Industry

This project, EPLQ: Efficient Privacy-Preserving Location-based Query over Outsourced Encrypted Data, can be utilized in various industrial sectors such as the retail industry, transportation and logistics, tourism and hospitality, and healthcare.
