Enabling Efficient and Geometric Range Query with Access
Control over Encrypted Spatial Data
ABSTRACT:
As a basic query function, range query has been exploited in many scenarios such
as Sql retrieves, location-based services, and computational geometry. Meanwhile,
with explosive growth of data volume, users are increasingly inclining to store data
on the cloud for saving local storage and computational cost. However, a long-
standing problem is that the user’s data may be completely revealed to the cloud
server because it has full data access right. To cope with this problem, a
frequently-used method is to encrypt raw data before outsourcing them, but the
availability and operability of data will be reduced significantly. In this paper, we
propose an Efficient and Geometric Range Query scheme (EGRQ) supporting
searching and data access control over encrypted spatial data. We employ secure
KNN computation, polynomial fitting technique and order-preserving encryption
to achieve secure, efficient and accurate geometric range query over cloud data.
Then, we propose a novel spatial data access control strategy to refine user’s rights
in our EGRQ. To improve the efficiency, R-tree is adopted to reduce the searching
space and matching times in whole search process. Finally, we theoretically prove
the security of our proposed scheme in terms of confidentiality of spatial data,
privacy protection of index and trapdoor, and the unlinkability of trapdoors. In
addition, extensive experiments demonstrate the high efficiency of our proposed
model compared with existing schemes.

IRJET- Secure Data Access on Distributed Database using Skyline QueriesIRJET Journal

This document proposes a methodology for secure data access on distributed databases using skyline queries. The methodology encrypts both the user's data and the database, so the distributed server has no knowledge of the stored data. It also includes "illusion data" uploaded by the user to prevent intruders from accessing the real data if a breach occurs. If an intruder accesses the stored data, they will only see the illusion data. The user and data owner will be notified of the intrusion. The methodology uses K-nearest neighbor and CNN algorithms to classify the results.

Testing spatial data deliverance in SQL and NoSQL DatabaseDany Laksono

This document summarizes research that tested the performance of delivering spatial data through SQL and NoSQL databases using a NodeJS fullstack web application. It describes testing different sized spatial datasets stored in PostGIS and MongoDB and delivered via a MEAN (MongoDB, Express, AngularJS, NodeJS) framework. The results showed that MongoDB performed better than PostGIS at delivering large spatial datasets, with response times increasing more sharply with dataset size for PostGIS. The document concludes that a MEAN framework could be used as an alternative to traditional LAMP frameworks for web GIS applications.

A time efficient approach for detecting errors in big sensor data on cloudShakas Technologies

This document describes a novel approach for detecting errors in big sensor data on cloud platforms. The approach classifies types of sensor data errors and exploits the network features of wireless sensor networks. It uses a scale-free network topology to conduct error detection on limited temporal or spatial data blocks rather than whole datasets, dramatically accelerating the detection and location process. The detection and location tasks are distributed across a cloud computing platform to fully utilize computation power and storage. Experiments on a cloud platform demonstrate the approach can significantly reduce time for error detection and location in large-scale sensor network data with accurate error detection.

Enabling secure and efficient ranked keywordIMPULSE_TECHNOLOGY

This document proposes a system for enabling secure and efficient ranked keyword search over outsourced cloud data. It summarizes that existing searchable encryption techniques only support basic Boolean search and do not consider relevance ranking. The proposed system explores using relevance scores from information retrieval to build a searchable index and develops a one-to-many order-preserving mapping technique to protect sensitive score information, allowing efficient server-side ranking without compromising keyword privacy. The system provides ranked search results while maintaining strong security guarantees.

Privacy preserving multi-keyword ranked search over encrypted cloud dataIGEEKS TECHNOLOGIES

This document proposes a system called privacy-preserving multi-keyword ranked search over encrypted cloud data (MRSE). Existing searchable encryption systems only support single-keyword or boolean keyword search without result ranking. The proposed MRSE system allows a user to search for multiple keywords and returns documents ranked by relevance. It establishes privacy requirements and uses an efficient "coordinate matching" semantic to quantify document similarity based on keyword matches. The system architecture includes modules for data owners to encrypt and upload files, for users to search and download encrypted files, and for ranking search results.

The document proposes a solution called privacy-preserving multi-keyword ranked search over encrypted cloud data (MRSE) that allows searching encrypted data stored in the cloud using multiple keywords. It establishes privacy requirements for such a system and uses an efficient "coordinate matching" similarity measure to determine relevance between search queries and documents. It first presents a basic MRSE scheme based on secure inner product computation, then improves upon it with two schemes that achieve different privacy levels while introducing low overhead on computation and communication as shown by experiments on real-world datasets.

The document describes a student project titled "Error Detection in Big Data on Cloud". The project aims to develop a time-efficient approach for detecting and correcting errors in large sensor data stored on the cloud. If errors are found, the approach also involves error recovery and storing the corrected data in its original format. The proposed method uses algorithms like cyclic redundancy check, Hamming code, and secure hash algorithm to detect and locate errors in big data sets efficiently. Design documents like data flow diagrams, use case diagrams and class diagrams were created to plan the system architecture and implementation of the project.

In attribute based encryption (ABE) scheme, attributes plays a very important role. Attribute –based encryption provides privacy protection for the users by a set of attributes. Now a days as cloud is most widely used in mostly all fields so there is need of keeping data more secure and confidential which is outsourced on the cloud. Security of the data in cloud database server is the key area of concern in the acceptance of cloud. It is required very high degree of privacy and authentication. In existing system used hierarchical authorization structure to reduce the burden and risk of a single authority .this paper proposes a hierarchical attribute based encryption which directly provides attribute value by user as well as data stored in different types of media.
