In an outsourced database service model, query assurance takes an important role among wellknown security issues. To the best of our knowledge, however, none of the existing research work has dealt with ensuring the query assurance for outsourced tree-indexed data. To address this issue, the system must prove authenticity and data integrity, completeness, and freshness guarantees for the result...

Cloud storage has rapidly become a cornerstone of many IT infrastructures, constituting aseamless solution for the backup, synchronization, and sharing of large amounts of data. Puttinguser data in the direct control of cloud service providers, however, raises security and privacyconcerns related to the integrity of outsourced data, the accidental or intentional leakage ofsensit...

The fingerprint recognition approach uses a variety of techniques, each which is based on particular criteria. Finding an effective method for the goal this work. project to provide straightforward, high-performance method. This strategy consists two main phases: first step actually collecting data from samples human fingerprints, and second focuses designing implementing highperformance featur...

One of the problems associated with outsourcing data to cloud service providers is the data integrity of outsourced data. In this paper we present data integrity techniques for the outsourced data. Data integrity encompasses the completeness, correctness and freshness of the data. This paper focuses on the Merkle Hash Tree based data integrity techniques. It also presents the techniques for sto...

Security guarantees are essential for the outsourced data, wh ich is maintained by third party cloud storage. To achieve s ecurity gu arantees f or t he out sourced data ba ckups, we design and implement a secure overlay cloud storage system called FADE. FADE achieves fine-grained, policy-based access control and file assured deletion. I t associates outsourced files with file access policies, ...

This paper examines the effect of international outsourcing of intermediate inputs on labour productivity at the level of the plant that engages in outsourcing. To do so we use plant level data for the electronics industry in the Republic of Ireland. Using a fresh perspective on international outsourcing and productivity, we focus on the nature of outsourced inputs (services or tangibles) and t...

Control of outsourced IT projects is an important topic in several research disciplines. This study brings together two approaches from auditing and IS literature in order to obtain deeper understanding of control mechanisms in complex outsourced IT projects. It is proposed that communication tools, viewed as “boundary objects”, are also useful for implementing control functions, such as risk a...

The Cloud has become a significant topic in computing; however, the trend has established a new range of security issues that need to be addressed. In Cloud, the data and associated software are not under their control. In addition, with the growing demands for Cloud networks communication, it becomes increasingly important to secure the data flow path. The existing research related to security...

Outsourcing database services is emerging as an important new trend thanks to continued developments of the Internet and advances in the networking technology. In this outsourced database service (ODBS) model, organizations rely upon the premises of an external service provider for the storage and retrieval management of their data. Since a service provider is typically not fully trusted, this ...
