Keyword Search in Decentralized Storage Systems

Keyword Join: Realizing Keyword Search in P2P-based Database Systems

In this paper, we present a P2P-based database sharing system that provides information sharing capabilities through keyword-based search techniques. Our system requires neither a global schema nor schema mappings between different databases, and our keyword-based search algorithms are robust in the presence of frequent changes in the content and membership of peers. To facilitate data integrat...

Index-Based Keyword Search in Mediator Systems

Many users and applications require the integration of semistructured data from autonomous, heterogeneous Web sources. Over the last years mediator systems have emerged that use domain knowledge to overcome the problem of structural heterogeneity. However, many users of these systems do not have a thorough knowledge of the complex global schemas and of the comprehensive query languages. Consequ...

Keyword-based Search in Data Integration Systems

In this paper we describe Keymantic, a framework for translating keyword queries into SQL queries by assuming that the only available information is the source metadata, i.e., schema and some external auxiliary information. Such a framework finds application when only intensional knowledge about the data source is available like in Data Integration Systems.

Secure Keyword Search with Public Key Encryption by Cloud storage

Secure Data Storage Outsourcing with Conjunctive Keyword Search

This thesis in the field of cryptography considers secure data outsourcing with keyword search capabilities. To ensure data confidentiality the data is stored in encrypted format. An efficient solution has been developed to enable conjunctive keyword search. Also, a protocol is applied to enable efficient and secure sharing of encrypted data. It is possible to efficiently enrol and revoke users...
