Decentralized Storage Systems — Offering Optimum Security and EfficiencyRepresenting decentralised cloud storageThe advancement in the digital realm has certainly streamlined and improved the way people received services. Presently, common masses have access to vast information and services on the go. However, data security and efficiency have been a critical challenge that companies across the globe are continuously dealing with. While present cloud storage options offer vast space, there are challenges that keep enterprises from completely relying on centralised data storage systems.Challenges of Existing Data Storage SystemsBelow are the fundamental setbacks of conventional data storage options:-Privacy and Security IssuesInternet privacy threats such as identity thefts, tracking, (...)

What Does Cloud #storage Mean to You?
▻https://hackernoon.com/what-does-cloud-storage-mean-to-you-78d4841b7baf?source=rss----3a8144eab
Over the past decade, cloud technologies have evolved from simple Infrastructure as a Service offerings to diversified services and middleware portfolios. One of the major areas of advancement is towards the cloud storage offerings.When discussing cloud storage, one of the common questions comes up is that what does cloud storage means to someone.If we look at modern cloud storage, it ranges from general purpose block storage comes for servers to higher level storage services such as Relational databases, NoSQL. In addition, the cloud offers different storage configurations for underlying infrastructure. As you can see, cloud storage is a broader topic which needs further understanding when selecting storages for different use cases.This article focuses on providing a higher level (...)
Getting Deep Into #ethereum: How Data Is Stored In Ethereum?

In this post we will see how states and transactions are stored in Ethereum and how it is different from Bitcoin.This post is a continuation of my Getting Deep Into Series started in an effort to provide a deeper understanding of the internal workings and other cool stuff about Ethereum and blockchain in general which you will not find easily on the web. Here is the first part of the Series:Getting Deep Into Geth: Why Syncing Ethereum Node Is SlowIn this post we will dive into Ethereum’s data storage layer. We will introduce the concept of blockchain “state”. We will cover the theory behind the Patricia Trie data structure and demonstrate Ethereum’s concrete implementation of tries using Google’s leveldb database.What do we store in storage layer?First of all we have to see that what all (...)

Storage Inspector - Firefox Developer Tools | MDN
▻https://developer.mozilla.org/en-US/docs/Tools/Storage_Inspector
The Storage Inspector enables you to inspect various types of storage that a web page can use. Currently it can be used to inspect the following storage types:
– Cache Storage (new in Firefox 47) - any DOM caches created using the Cache API.
– Cookies - All the cookies created by the page or any iframes inside of the page. Cookies created as a part of response of network calls are also listed, but only for calls that happened while the tool is open.
– Local Storage - All local storage items created by the page or any iframes inside the page.
– Session Storage - All session storage items created by the page or any iframes inside the page.
– IndexedDB - All IndexedDB databases created by the page or any iframes inside the page, their Object Stores and the items stored in these Object Stores.
For the time being, the Storage Inspector only gives you a read-only view of storage. But we’re working to let you edit storage contents in future releases.

#Dropbox #bug results in users losing data
This affects people using some older versions of the desktop app and enabling the Selective Sync option.
Typically, this would happen after a crash or forced reboot, making a bad problem worse — at least a few users found that they’d lost years’ worth of content through no fault of their own.

Snowden : Get rid of #Dropbox, avoid #Google and #Facebook
▻http://techcrunch.com/2014/10/11/edward-snowden-new-yorker-festival
Comme alternatif à Dropbox il suggère #SpiderOak ▻http://blogs.wsj.com/digits/2014/07/17/snowden-says-drop-dropbox-use-spideroak
The difference between Dropbox and SpiderOak is that SpiderOak encrypts the data while it’s on your computer, as opposed to only encrypting it “in transit” and on the company’s servers.
Il propose aussi de protégér vos SMS et appels téléphoniques avec des outils comme ceux de #Whispersystems (#Redphone, #TextSecure) ►https://whispersystems.org et #Silent_Circle ►https://silentcircle.com

INTERNET • Edward Snowden : « Laissez tomber Dropbox, Facebook et Google » | Courrier international
▻http://www.courrierinternational.com/article/2014/10/13/edward-snowden-laissez-tomber-dropbox-facebook-et-google
Pour Edward Snowden, le meilleur moyen de protéger sa vie privée en ligne, c’est de laisser tomber les services comme Google, Facebook et Dropbox. C’est ce qui ressort de l’interview que l’homme à l’origine des révélations sur la NSA a accordée ce week-end dans le cadre du New Yorker Festival. Le site Techcrunch revient sur les conseils distillés par Snowden.
Première recommandation : ne pas utiliser les services « hostiles à la vie privée », comme DropBox, qui ne permettent pas de crypter les données. Snowden précise que même si Facebook et Google ont amélioré leur niveau de sécurité, ils restent des services « dangereux ». Techcrunch souligne avec ironie que « les internautes qui suivaient l’interview en direct sur Google Hangouts ou YouTube pouvaient voir un logo Google au-dessus du visage de Snowden en même temps qu’il prononçait ces mots ». Dernier conseil de Sno_wden : « N’envoyez pas de SMS non cryptés. Utilisez les services comme RedPhone et Silent Circle [des applications de cryptage pour smartphone]. »
« _Certains disent qu’ils n’ont ’rien à cacher’, mais dire cela, c’est inverser les responsabilités », a expliqué Edward Snowden. « Dire : ’Je n’ai rien à cacher’, cela revient à dire : ’Je me fiche de ce droit’. C’est dire : ’Je ne dispose tellement pas de ce droit que j’en suis arrivé au point où je dois m’en justifier’. Alors que normalement, c’est le gouvernement qui doit se justifier de ne pas respecter vos droits », a-t-il développé, pour appuyer son appel à une réforme de la politique américaine en matière de respect de la vie privée.
Storj - The Future of #cloud #storage

World’s first #blockchain-based #decentralized storage network.(Permalink)
Apparemment ce marché du stockage distribué se développe petit à petit. Environ 5000 « clients Storj » aujourd’hui. Quelqu’un s’est lançé dedans ?
Je venais juste de découvrir Storj à travers la vidéo de Gordon Hall « The cloud is Dead - Long Live the Fog ! ». Je suis venu voir seenthis ensuite pour voir si le fil existait à ce sujet :)

Introducing BRIC (Bunch of Redundant Independent Clouds) « Bitcartel Blog
►http://bitcartel.wordpress.com/2012/10/21/rbic-redundant-bunch-of-independent-clouds
Online storage providers are handing out free storage like candy. Add them all up and soon you’re talking about a serious amount of space. So let’s have some fun by turning ten different online storage providers into a single data grid which is secure, robust, and distributed. We call this grid a BRIC (Bunch of Redundant Independent Clouds).
The BRIC solution presented here will use the open source project Tahoe-LAFS to perform the RAID like function of striping data across different storage providers. Here’s how Tahoe-LAFS describes itself:
Tahoe-LAFS is a Free and Open cloud storage system. It distributes your data across multiple servers. Even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to function correctly, including preservation of your privacy and security.

Novel #Energy #Storage Membrane
►http://english.farsnews.com/newstext.php?nn=9007100410
Dr Xie and his team have developed a membrane that not only promises greater cost-effectiveness in delivering energy, but also an environmentally-friendly solution. The researchers used a polystyrene-based polymer to deposit the soft, foldable membrane that, when sandwiched between and charged by two metal plates, could store charge at 0.2 farads per square centimeter. This is well above the typical upper limit of 1 microfarad per square centimeter for a standard capacitor.
JungleDisk and Amazon S3: Secure, Redundant, Encrypted Backup | Andy Wibbels

When first announced, S3 didn’t make much of a splash with consumers because there weren’t any applications for it yet - it was simply a service waiting for the geeks to write something fantastic for it. That fantastic application is here: JungleDisk.
