Cloud Storage

Cloud storage services are a lot of well-liked today . To secure information from those that don't have
access, several encoding schemes are projected. Most of the projected schemes assume cloud storage
service suppliers or trustworthy third parties handling key management are trustworthy and can't be
hacked; but, in follow, some entities could intercept communications between users and cloud storage
suppliers and so compel storage suppliers to unleash user secrets by victimisation government power or
alternative means that. During this case, encrypted information are assumed to be identified and storage
suppliers are requested to unleash user secrets. Since it's tough to fight against outside coercion, we tend
to aimed to create Associate in Nursing encoding theme that might facilitate cloud storage suppliers avoid
this plight. We provide cloud storage suppliers means that to make pretend user secrets. Given such
pretend user secrets, outside coercers will solely obtained solid information from a user’s keep cipher text.
Once coercers suppose the received secrets are real, they'll be happy and a lot of significantly cloud
storage suppliers won't have discovered any real secrets. Therefore, user privacy continues to be
protected.

E-medical systems play a quite essential role in the digital transformation of health care record, which allows a patient or the user to create, manage, and control its private Personal Health Record (PHR) through the internet [1][2]. Most of the E-Medical record services are outsourced to a third-party that is public cloud. However, such outsourcing of data may lead to a variety of privacy and security related issues because of the risk of information leakage. To avoid such problems, we are developing systems in which data will be encrypted using 3DES algorithm before uploading to the cloud. Subsequently, only the authorized client who has the key or permissions can decrypt the data. E-Medical records are basically sensitive and should be stored in database in encrypted form. Once medical records are encrypted and outsourced, the cloud server can no longer perform keyword search, because the server is not expected to obtain any information about the records. Hence, the goal of the project is to provide security to personal health records where data needs to be kept private.

Cloud Computing is seen as greatly accessible computing resources as an outward service granted from the world wide web. As an economical view, the cloud computing key is that consumers are free to use whatever they want, and pay for the services they want. The accessibility of the resources from the cloud is obtainable whenever users want and wherever they are. Therefore, users are free to purchase the IT service that they want and they do not have to be concern more about the manner that maintainable things can be beyond the positions. New model for data storage computing which considers as a web-based generation utilizes remote servers. The challenging needed to be undertook in cloud computing is the safety of information of service sources' site. Thus, this study suggests that designing new construction for the security of information storage with variety functions where information encrypted and split into many cipher blocks and disseminated between a large number of services suppliers locations instead of merely relying on only one supplier for information storage. Proposed based in the new architecture, it is applicable to ensure a better security, availability and reliability.

Cloud Storage Systems are increasingly noticed now-a-days as they are promising elastic capability and high reliability at low cost. In these services, the files are stored in an authenticated cloud storage service center. The most important feature is storage is adjusted dynamically, and there won’t be any worry about space being inadequate or wasted. This paper presents a solution for deploying an Object Cloud Storage Service System based on the open-source cloud Operating System OpenStack and Swift.

Data are one of the major and core assets of every organization. Obviously there is a need for the data of any organization to be stored. There are different types of storage devices catering for different characteristics such as capacity, scalability, reliability, performance, and cost. Navigating and selecting a suitable storage device for a given purpose requires an understanding of the different storage devices available. The objective of this chapter is to describe the various storage devices, how they have progressed from being conventional storage devices to cloud storage devices, and how data and the need for digitization have evolved.

Blockchain Technology is an emerging technology in the software world. In order to understand the applications of the blockchain, it is necessary to understand how blockchain works. Blockchain was first introduced by Satoshi Nakamoto in 2008, which serve a Peer-to-Peer ledger for registering cryptocurrency bitcoin transactions. The blockchain is a list of records stored in the form of a chain. A blockchain is a decentralized distributed ledger which means a number of records are stored in a block and the block is added to the chain. Each block consists of a number of transactions for each transaction there will be a unique hash value, all hash values of the number of the transaction are combined and made a single hash value of the block and this follows Merkle root hash method. The invention of blockchain in cryptocurrency bitcoin solved the issue of double spending. The invention of blockchain in data backup can decrease the security complexity and duplication of the data. Rather than storing the data in one single hub that is the centralized system we can store the data in the blockchain which is a decentralized distributed ledger. In this decentralized system, the file is divided into a number of chunks stored into the blockchain which makes it difficult for data hacking and data tampering. In a centralized system if a server goes down then data is lost forever and in centralized system records can easily be altered because it does not have a backup to verify the records but in the blockchain, every peer in the network has the copy of the records and it is difficult to tamper the records. The files can be divided by a technology called Reed-Soloman erasure coding, generally used in CDs and DVDs. Reed-Soloman erasure coding allows dividing files in a redundant manner, where any 1 of 3 segments can fully recover a user's file.

Cloud storage is a service where data is remotely maintained, managed and backed up. The service is available to users over a network, which is usually the internet. It allows the user to store files online so that the user can access them from any location via the internet. The provider
company makes them available to the user online by keeping the uploaded files on an external server. This gives companies using cloud storage services ease and convenience, but can potentially be costly. Users should also be aware that backing up their data is still required when using cloud storage services because recovering data from cloud storage is much slower than the local backup. Although there are downsides to cloud storage, many organizations believe the benefits to far outweigh the risks. The cost savings, disaster-recovery, security, and accessibility are just a few intriguing benefits to businesses. Cloud storage can reduce costs, simplify IT management, improve user experience, and allow employees to work and collaborate from remote locations. This simplifies sharing and collaboration among staff and easing IT logistics as a whole.

A reliability model for the hard disk drive (HDD) is developed, focusing on head-disk separation as the primary independent variable. Among the many factors contributing to reliability, the role of water vapor is described for the first time. An experimental method based on magnetic spacing loss theory is used to characterize the head-media separation as a function of temperature, altitude, humidity, and HDD operating mode. A statistical model based on these empirical data is developed to predict HDD reliability for various operating conditions. The predictive capability of the model is verified experimentally through application to HDD product reliability test data.

The present essay is organized into five main sections. We begin with a few preliminary remarks about “cloud computing, ” which are developed more fully in a later section. This is followed by a brief overview of the evolution of Helen Nissenbaum’s framework of “privacy as contextual integrity. ” In particular, we examine Nissenbaum’s “Decision Heuristic ” model, described in her most recent work on privacy (Nissenabum 2010), to see how it enables the contextual-integrity framework to respond to privacy challenges posed by new and emerging technologies. We then apply that heuristic device to questions surrounding one aspect of cloud computing – viz., “cloud storage ” technology. In particular, we focus on current practices affecting Google Docs as an instance of a cloud-storage system.

— With technological advancements and constant changes of Internet, cloud computing has been today's trend. With the lower cost and convenience of cloud computing services, users have increasingly put their Web resources and information in the cloud environment. Increasing data volume is giving the bigger task of Data Centers to provide a better quality of cloud computing. The main usage of cloud computing is data storage. It is more reliable and flexible to users to store and retrieve their data at anytime and anywhere. the security of cloud computing plays a major role in the cloud computing, as customers often store important information with cloud storage providers but these providers may be unsafe. Customers are wondering about attacks on the integrity and the availability of their data in the cloud from malicious insiders and outsiders, and from any collateral damage of cloud services. These issues are extremely significant but there is still much room for security research in cloud computing. This paper presents a framework for global data security of the cloud with two-level Security model. The proposed framework is intended for adapting a system and the framework allows the network service provider to deploy a security in different data centers dynamically while the customers need more security for increasing the data storage.

Multi-client framework for access control to datasets set away in an untrusted cloud condition. Appropriated storing like some other untrusted condition needs the capacity to check share data. Our framework gives a path of authority over the informational index away in the cloud without the supplier adventure. The fundamental instrument of access control structure is the figure content arrangement trademark based encryption plot with dynamic properties. Utilizing a blockchain based decentralized record, our framework gives the steady log of all vital security occasions, for example, key age, get the chance to strategy undertaking, change or refusal, and get the chance to ask for. We propose a huge amount of cryptographic conventions guaranteeing the security of cryptographic endeavors requiring conundrum or private keys. Just ciphertexts of hash codes are exchanged through the blockchain record. The model of our structure is acknowledged utilizing sharp contracts and endeavored on square chain sort out. Here is proposed structure as a customer if they are going to enroll in that account director will give assorted keys to each customer it takes after a private key in the wake of selecting a customer they can log in and they can exchange all of the reports what they need while exchanging time the substance everything will be encoded and for that one open key will be produce these all will be secured in cloud database. As a customer they have an alternate privet key which was given by the manager so they can log in and they can get to that account if they have to exchange they can exchange else they have to get any record they can get that record by using of cloud they can see all the customer archives if they need any record they have to send sales to executive .if overseer to recognize that request they can get that interface if the customer need that record they have to click that record in case you clicked that archive, by then it will be asked first it will ask private key. Obviously, it will ask with respect to whether two keys was composed then nobody however they can prepared to download else they can't prepared to down weight .

Today, gas leakage and detection are important issues in our everyday lives. Gas waste is also a big issue that must be addressed. LPG gas is very combustible and can endanger both people and property. To avoid such scenarios, substantial effort has been given to the development of accurate systems for detecting gas leaks. Because simply knowing that a leak exists isn't always enough to initiate remedial action, several leak detection techniques were created to provide for the potential of identifying the leak. Our goal is to use the Internet of Things to decrease hazards in the kitchen. The main goal is to propose the design and implementation of a Gas Leakage Alert System based on SMS. Gas sensors are used in kitchens to detect gas leaks. The issue of gas wastage is also checked with the assistance of an infrared sensor. When the sensor detects no vessel over the burner for an extended length of time, an alert is triggered.

Cloud storage is a service that moves user‟s data into large data centers. Here datas are remotely located, maintained, managed and backed up through internet. Cloud provides the way for check the integrity of user‟s data if he can‟t access the data physically. In this paper we provide the proof of retrievability (POR) scheme to ensure the data integrity in cloud based on SLA (service level agreement). In addition we provide a dynamic audit service for verifying the integrity of outsourced and untrusted storage of data by using method based on probabilistic query and periodic verification for improving the performance of audit services

Abstract. The ever growing technology has resulted in the need for storing and processing excessively large amounts of data on cloud. The current volume of data is enormous and is expected to replicate over 650 times by the year 2014, out of which, 85% would be unstructured. This is known as the ‘Big Data’ problem. The techniques of Hadoop, an efficient resource scheduling method and a probabilistic redundant scheduling, are presented for the system to efficiently organize "free" computer storage resources existing within enterprises to provide low-cost high-quality storage services. The proposed methods and system provide valuable reference for the implementation of cloud storage system. The proposed method includes a Linux based cloud.

Infrastructure as a Service is a form of cloud computing that provides virtualized computing resources over the Internet. This paper provides a short overview of how to create instance based on user request and how to set priority and schedule the instance. In this project use generalized priority algorithm and PSO (particle swarm optimization based scheduling) to manage the instance. The use of generalized priority algorithm is to prioritize the user requests based on size, Memory and bandwidth and also use to rank the instance based on cloudlet. The working procedure of PSO used to outsource its task to external clouds when its own resources are not sufficient to meet the demand and at the same time guarantee the QoS (Quality of Service). It is similar to outsourcing during hike period. Users also can store their data to cloud. By the help of advanced encryption standard and diff algorithm increase reliability and efficiency by encrypting user files and remove duplicate data from cloud.

The essential function of the learning management system (LMS) is to manage and the learning object. Therefore, storage capacity becomes critical component when the content and the user is growing. Some of the existing LMS experience problems to store many files because of limited storage capacity and also the inability of the LMS has scalability on the storage. This paper makes an effort to improve the LMS capability on storage capacity by integrating the LMS storage with the cloud storage. Specifically, this paper proposes low cost consumer cloud storage to be used for storage extension on the LMS. This paper discusses about the comparison between several consumer cloud storage and its integration strategy. As a result, this paper can be a consideration when choosing a cloud storage for LMS or e-learning.

The focus of this paper is to secure sensitive data on smartphones using cloud infrastructure. Nevertheless, the biggest challenge is data security. This work, therefore, addresses the issues of security of user data by using cloud storage with the development of Solo App v2.1 android application which adopted an Advanced Encryption Standard (AES) for maintaining the confidentiality of data. This will enable smartphones data to remain secure either at rest or in transit. Since numerous threats to mobile phones nowadays have made the issue of security of data on smartphones very critical, hence, the need for the development of such application. Three Android devices were used for the experiments to implement the application. The results are presented using time performance metrics that is based on encryption time and decryption time for each device. The results showed that the work can effectively protect user sensitive data with speed using cloud and when compared with existing works, the results are satisfactory.

In present day technological generation still, maximum of the housing societies use the old-age conventional technique for the administration work of the society. The bill generation is still done manually for each society member, and there can be hundreds of them, which is time-consuming. Keeping records of those bills and keeping track of their status is a harrowing process. All the information of the members and society's accounts is not safe on the papers. The proposed application is android based, which makes it easier for all the members to adopt it. This is enforced with Two-Factor Authentication making it fairly secure. The Admin can easily generate and view bills and monitor the billing status of all the members. The members will get notified of their pending bills. Other facilities provided in this app are a platform for scheduling events and meetings, making announcements and providing a summary of the meeting. So this app takes care of the overall needs of a housing society.

Cloud security is the most critical task while considering its working environment, i.e. outsourced, distributed and utility based. In such cases making the users data confidential, increases the trust over the system. Also the security procedure does not make the availability affected in any ways. The users of these kind of systems is always retained the services and securities preliminaries with respect to the data itself. As the cloud user can access its data frequently and if here some encryption is used which requires decryption and the repetitive process continues to increase the overheads. It requires some mechanism in which encryption is performed and if the user requires to perform some operations on secure file without decrypting it can be fulfilled. Thus homomorphic encryption lets the user facilitates about the performing operations on encrypted data which reduces the complexity of confidentiality operations. Also to prevent Cloud Servers from being able to learn both the data file contents and user access privilege information used to generate key along with the fastest access of secured data by using Attribute-based encryption (ABE).

Volume 2, Issue 4 July – August 2013 Page 342 Abstract: Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Instead of running programs and data on an individual desktop computer, everything is hosted in the “cloud”. It offers a major change in how to store information and run applications. One of the primary uses of cloud computing is for data storage. With cloud storage, data is stored on multiple third-party servers, rather than on the dedicated servers used in traditional distributed data storage. In cloud storage, the user sees a virtual server; it appears as if the data is stored in a particular place with a specific name. But that place doesn’t exist in reality. It’s just to reference a virtual space in the cloud. This paper gives a quick introduction to cloud storage. It discusses the need for cloud storage, the main developing requirements and the challenges to cope with the changing IT and business environment. It revi...
