A Noval Method for Data Auditing and Integrity Checking in Public Cloud

Data plays a huge role in today’s era. All business requires to deal with lot of business. So data has to be secured correctly. In this paper we aim to design a system to help to protect the data in the cloud. The public cloud is used in which the users stores the data and the data is secured by using the cryptographic method. Every customer wants to store the data and access or process the data from the cloud, but the major setback is security issues. In this paper we present a novel algorithm which helps the data to be accessed securely from the cloud

Identity-Based Proxy-Oriented Data Uploading and Remote Data Integrity Checking in Public Cloud

More and more clients would like to store their data to public cloud servers (PCSs) along with the rapid development of cloud computing. New security problems have to be solved in order to help more clients process their data in public cloud. When the client is restricted to access PCS, he will delegate its proxy to process his data and upload them. On the other hand, remote data integrity checking is also an important security problem in public cloud storage. It makes the clients check whether their outsourced data are kept intact without downloading the whole data. From the security problems, we propose a novel proxy-oriented data uploading and remote data integrity checking model in identity-based public key cryptography: identity-based proxy-oriented data uploading and remote data integrity checking in public cloud (ID-PUIC). We give the formal definition, system model, and security model. Then, a concrete ID-PUIC protocol is designed using the bilinear pairings. The proposed ID-PUIC protocol is provably secure based on the hardness of computational Diffie–Hellman problem. Our ID-PUIC protocol is also efficient and flexible. Based on the original client’s authorization, the proposed ID-PUIC protocol can realize private remote data integrity checking, delegated remote data integrity checking, and public remote data integrity checking

Bilinear Pairings Technique on Concrete ID-PUIC Protocol

We propose a novel intermediary arranged information transferring and remote information uprightness checking model in identity-based public key cryptography: IDPUIC (identity-based proxy-oriented data uploading and remote data integrity checking in public cloud). We give the formal definition, framework model and security display. At that point, a solid ID-PUIC protocol is planned by utilizing the bilinear pairings. The proposed ID-PUIC protocol is provably secure in view of the hardness of CDH (computational Diffie-Hellman) issue. Our ID-PUIC protocol is additionally productive and adaptable. In view of the first customer's approval, the proposed ID-PUIC protocol can understand private remote information uprightness checking, appointed remote information integrity checking and open remote information integrity checkin

Integrated, reliable and cloud-based personal health record: a scoping review.

Personal Health Records (PHR) emerge as an alternative to integrate patient’s health information to give a global view of patients' status. However, integration is not a trivial feature when dealing with a variety electronic health systems from healthcare centers. Access to PHR sensitive information must comply with privacy policies defined by the patient. Architecture PHR design should be in accordance to these, and take advantage of nowadays technology. Cloud computing is a current technology that provides scalability, ubiquity, and elasticity features. This paper presents a scoping review related to PHR systems that achieve three characteristics: integrated, reliable and cloud-based. We found 101 articles that addressed thosecharacteristics. We identified four main research topics: proposal/developed systems, PHR recommendations for development, system integration and standards, and security and privacy. Integration is tackled with HL7 CDA standard. Information reliability is based in ABE security-privacy mechanism. Cloud-based technology access is achieved via SOA.CONACYT - Consejo Nacional de Ciencia y TecnologíaPROCIENCI
