Analysis of Authentication Mechanisms for Outsourced Spatial Databases

With the growing popularity of location-based services and the excessive usage of smart phones an... more With the growing popularity of location-based services and the excessive usage of smart phones and GPS enabled devices, the practice of outsourcing spatial data to third party service providers has grown rapidly over the past few years. Meanwhile, the fast arising trend of Cloud storage and Cloud computing services has provided a flexible and cost-effective platform for hosting data from businesses and individuals, further enabling many location-based applications. However, in this database outsourcing paradigm, the authentication of the query results at the client remains a challenging problem. This paper presents an overview and analysis of the Outsourced Spatial Database (OSDB) model in spatial datasets and the security techniques suggested in literature for ensuring the authenticity of the query results obtained by manipulating these outsourced databases. IndexTerms – Outsourced Spatial Database, Security, and Authentication.

Gradual Class Evolution Detection Using Class Based Ensembles

The recent advances in hardware and software have enabled the capture of different measurements o... more The recent advances in hardware and software have enabled the capture of different measurements of data in a wide range of fields. These measurements are generated continuously and in a very high fluctuating data rates. Mining data streams is concerned with extracting knowledge structures represented in models and patterns in nonstopping streams of information. The research in data stream mining has gained a high attraction due to the importance of its applications and the increasing generation of streaming information. Mining data streams is concerned with extracting knowledge structures represented in models and patterns in non-stopping streams of information. Data Stream classification poses major challenges than classifying static data because of several unique properties of data streams such as infinite length, concept drift, concept evolution and feature evolution. While extensive work has been done in the area of concept drift, concept evolution, a phenomena that induces conc...

Spatial Query Authentication using Merkle QuadTree

Meanwhile, the fast arising trend of cloud storage and cloud computing services has provided a flexible and costeffective platform for hosting data from businesses and individuals, further enabling many locationbased applications. However, in this database outsourcing paradigm, the authentication of the query results at the client remains a challenging problem. This paper presents a novel method for authentication of query results based on the ideas of Authentication Data Structures. The idea of Merkle Hash Tree is adopted which allows a client to verify the correctness and completeness of the result set. A novel authentication scheme is suggested based on the concepts of Merkle Hash Tree and quadtree for verifying the authenticity of outsourced spat...
