Secure Data Sharing in the Cloud

With the increase in use comes a heightened demand for security and privacy. This project will conduct a thorough study of a key transport proto- col developed at NTNU, which targets strong security as its preeminent property, including a form of forward secrecy. More specifically, it will investigate how this escalation in security level affects the performance and usability of the protocol. How will the new protocol designed with security as its primary concern compare against other already established schemes when it comes to efficiency and practicality? Abstract Cloud sharing security is an important topic in today’s society. The majority of the most common cloud sharing solutions require that the user trust the Cloud Service Provider (CSP) to protect and conceal uploaded data. -
Photos Copied" Box
Our photos have never been as scattered as they are now... Do you know where your photos are? Digital Photo Roundup Checklist www.theswedishorganizer.com Online Storage Edition Let's Play Digital Photo Roundup! Congrats on making the decision to start organizing your digital photos! I know the task can seem daunting, so hopefully this handy checklist will help get your moving in the right direction. LET'S ORGANIZE! To start organizing your digital photos, you must first gather them all into one place, so that you'll be able to sort and edit your collection. Use this checklist to document your family's online storage accounts (i.e. where you have photos saved online), and whether they are copied onto your Master hub (the place where you are saving EVERYTHING). It'll make the gathering process a whole lot easier if you keep a record of what you have already copied and what is still to be done. HERE'S HOW The services in this checklist are categorized, so that you only need to print out what applies to you. If you have an account with the service listed, simply check the "Have Account" box. When you have copied all the photos, check the "Photos Copied" box. Enter your login credentials under the line between the boxes for easy retrieval. If you don't see your favorite service on the list, just add it to one of the blank lines provided after each category. Once you are done, you should find yourself with all your digital images in ONE place, and when you do, check back on the blog for tools to help you with the next step in the organizing process. -

Building Large-Scale Distributed Applications on Top of Self-Managing Transactional Stores
Building large-scale distributed applications on top of self-managing transactional stores June 3, 2010 Peter Van Roy with help from SELFMAN partners Overview Large-scale distributed applications Application structure: multi-tier with scalable DB backend Distribution structure: peer-to-peer or cloud-based DHTs and transactions Basics of DHTs Data replication and transactions Scalaris and Beernet Programming model and applications CompOz library and Kompics component model DeTransDraw and Distributed Wikipedia Future work Mobile applications, cloud computing, data-intensive computing Programming abstractions for large-scale distribution Application structure What can be a general architecture for large-scale distributed applications? Start with a database backend (e.g., IBM’s “multitier”) Make it distributed with distributed transactional interface Keep strong consistency (ACID properties) Allow large numbers of concurrent transactions Horizontal scalability is the key Vertical scalability is a dead end “NoSQL”: Buzzword for horizontally scalable databases that typically don’t have a complete SQL interface Key/value store or column-oriented ↑ our choice (simplicity) The NoSQL Controversy NoSQL is a current trend in non-relational databases May lack table schemas, may lack ACID properties, no join operations Main advantages are excellent performance, with good horizontal scalability and elasticity (ideal fit to clouds) SQL databases have good vertical scalability but are not elastic Often only weak consistency guarantees, such as eventual consistency (e.g., Google BigTable) Some exceptions: Cassandra also provides strong consistency, Scalaris and Beernet provide a key-value store with transactions and strong consistency Distribution structure Two main infrastructures for large-scale applications Peer-to-peer: use of client machines ← our choice (loosely coupled) Very popular style, e.g., BitTorrent, Skype, Wuala, etc. -

Received 15 May, 2015; Accepted 13 July, 2015 This study aims to show the present conditions about the usage of cloud computing in the department of Computer Education and Instructional Technology (CEIT) amongst teacher trainees in School of Necatibey Education, Balikesir University, Turkey. In this study, a questionnaire with open-ended questions was used. 17 CEIT teacher trainees participated in the study. The aim of this qualitative study was to determine trends about cloud technology. The cloud technology under study included “Dropbox”, “SpiderOak”, “Google Drive”, “IDrive”, “pCloud”, “OpenDrive”, “Bitcasa”, “OneDrive”, “Tresorit”, “Box” and “Yandex.Disk. The CEIT teacher trainees’ opinions about cloud storage and its purposes; their opinions about types of cloud storage and the level of importance of cloud storage were investigated. The reliability and validity were taken. The advantages and disadvantages of cloud computing were examined. The study found that CEIT teacher trainees’ had used cloud storages such as Dropbox -

Use It Wisely and Securely Cloud Storage
The Computer Corner By: George Birmingham, ET1(SS), Gold ’69-‘74 Cloud Storage – Use it wisely and securely Cloud Storage, for better or worse, is with us to stay. So what is cloud storage you may be asking? Cloud storage is a cloud computing model that stores data on the Internet through a cloud computing provider who manages and operates data storage as a service. It's delivered on demand with just-in-time capacity and costs, and eliminates buying and managing your own data storage infrastructure. So who offers cloud storage? Here are the providers as noted by PC Magazine as the Top 10 Cloud storage providers: · IDrive Review. MSRP: $69.50. ... · SugarSync Review. MSRP: $89.88. ... · Dropbox Review. MSRP: $0.00. ... · Microsoft OneDrive Review. MSRP: $0.00. ... · Box (Personal) Review. MSRP: $10.00. ... · CertainSafe Digital Safety Deposit Box Review. ... · Google Drive Review. ... · SpiderOak ONE Review. · Apple iCloud Free https://www.pcmag.com/picks/the-best-cloud-storage-and-file-sharing-services (14-Jun-2019) You will note that Dropbox and Microsoft OneDrive are in the list and they are available either natively in Windows 10 (OneDrive) or as an available app from the AppStore (Dropbox). If you decide to use a cloud storage solution, please read any and all Privacy Statements and Terms and Conditions very carefully before signing up. Since OneDrive and Dropbox are most common in Windows 10, here are some links to look at: https://www.dropbox.com/privacy (01-Jan-2020) https://www.itprotoday.com/development-techniques-and-management/ask-winobs-how-secure-are- my-onedrive-files (06-Oct-2017) Be sure to note who has access, how and with whom they share the data they hold, what kind of data they collect about you, where the encryption keys for your files are stored, who can access those keys, and if data is encrypted while in storage. -
