Beginning today, Bitcasa will be offering 5GB of cloud storage through a 60-day free trial. Legacy users of our 5GB Free service will be given 60 days to upgrade or move their files before their accounts are deleted. Our paid plans will remain at $99/year for 1TB and $999/year for 10TB.

This change will impact a very small percentage of the data currently stored with Bitcasa, and will allow us to better focus our engineering efforts on our larger and more active user base.

Further, this change will not impact any of our partner agreements. In fact, they better align our business with our platform partners: free trials are stickier and more profitable than free tiers.

If you have any questions or concerns, please visit our Help Center.

San Mateo, CA – March 29, 2016 – Bitcasa, the cloud drive for the device economy, today announced the new CloudFS software driver, which allows any device to access cloud storage at the OS level, eliminating the need for local storage.

Made possible by Bitcasa’s virtual drive architecture, which uses the cloud as primary storage as opposed to a sync mechanism, the new software allows partners with Portable Operating System Interface (POSIX) compliant file systems and local caching requirements to natively cloud-enable devices. Integration is as easy as adding a local drive.

“Unlocking the true potential of connected devices requires an end to the dependency on local storage,” said Brian Taptich, CEO of Bitcasa. “Our new CloudFS driver is the first step towards a platform that enables any developer to add the cloud as a ubiquitous setting in their hardware or software solution.”

The new CloudFS driver is able to securely store all data types, including media, apps, contacts, and settings, by embedding the cloud at the OS level. This allows a user’s entire digital life to be kept organized and accessible across any device regardless of local storage constraints.

Potential uses for the driver range from handsets that offer iCloud-like backup and transfer capabilities, to small IoT devices with no local storage running applications directly from the cloud, and hybrid servers created to manage elastic capacity requirements. The CloudFS driver will benefit partners and their ecosystems by providing:

  • Simple integration – a cloud drive can be mounted to a device OS as easily as a local drive, using a software driver and APIs that allow apps to communicate with the driver.
  • Native experiences – the cloud appears as another local drive to users, is managed through the device settings menu, and provides developers with direct read/write access.
  • Patented security – includes Bitcasa’s recently patented zero-knowledge encryption method that also improves network efficiency to keep data safe.

The new CloudFS software driver is currently available through Bitcasa’s product discovery program to qualified partners. The program includes a command line sample reference application and complete documentation. Interested parties can apply for access here.

About Bitcasa

Bitcasa is transforming the drive. By providing secure APIs and white label storage applications for OEMs, network operators, and software developers, Bitcasa helps the device economy create deeper relationships with their customers in over 140 countries worldwide. The Bitcasa Platform enables secure file storage, access, and sharing across all major platforms including Android, iOS, Windows, Mac OSX, Linux, and the Web. Bitcasa is backed by top-tier investors, including Horizons Ventures, Pelion Venture Partners, First Round Capital, Samsung Ventures and Andreessen Horowitz.

The United States Patent and Trademark Office (USPTO) has issued U.S. Patent 9253166, which combines Bitcasa’s industry-leading security model with more efficient bandwidth utilization using deduplication and smart caching techniques. The patent describes Bitcasa’s process of simultaneous, convergent encryption and deduplication, combined with smart caching, which is accomplished using three methods:

  • Each block of data is encrypted using its own self-generated convergent key. These keys are themselves encrypted by a self-generated master key that only each user knows,
  • The client device minimizes bandwidth utilization by determining whether the encrypted data blocks to transfer are already present in the cloud,
  • The client device informs the cloud drive which data is likely to be required in the future so it can be made available with less latency if the client device requests the data.

Bitcasa Security and Efficiency Illustration

Deduplication allows Bitcasa to benefit from the operational efficiencies resulting from the exclusion of redundant data. Cost-savings are passed on to partners, while users benefit from zero-knowledge encryption and a better user experience. Watch our video for more information about Bitcasa’s industry-leading security model.

Filed in May of 2012, and issued on February 2, 2016, US Patent 9253166 includes 162 claims, all of which are detailed on the US Patent & Trademark Office, Patent Full Text and Image Database.

Amazon Fire Devices: To Encrypt or Not to Encrypt?

Should this be a question?

Last week Amazon Fire device users learned that locally stored app data, logins, credit card credentials, photos, videos, texts, calendar and emails would no longer be encrypted.  It was strange timing to hear about deprecating encryption standards, as Apple goes head to head with the United States government over the unlocking of the San Bernadino shooter’s phone.

Amazon reversed this decision over the weekend, which is probably a sigh of relief for Amazon Fire device users.

At Bitcasa, we don’t expect users to opt-in or out of securing their content.  Encryption is not a question, it just is.

4K / UHD Content Will Drive a Significant Increase in Cloud Storage Demand

Consumers have been driving demand for 4K / Ultra High Definition (UHD) since 2014.  Now both established and new brands are entering the market, making 4K / UHD content much easier to create and access. Last week’s Mobile World Congress continued the trend, with a number of related announcements:

  • Samsung and Verizon announced the ability to transmit 4K content to a moving vehicle
  • Huawei announced GigaRadio featuring HD voice, 2K/4K HD video and virtual reality experiences
  • Qualcomm discussed the 6th generation of the Snapdragon X16 smartphone modem
  • AstroFlix announced the first 4K Zodiac Channel for horoscope delivery in 4K

However, with improved content quality comes additional local storage challenges for users who create and consume 4K / UHD files. The files are gigantic. Look at the difference versus HD on the iPhone 6s at 60 frames per second:

Screen Shot 2016-02-29 at 9.13.24 PMSo if you have a 16GB phone you better offload that content fast, or find a cloud solution – and Apple will offer that to you. Live photos generate 4 shots per picture. So at about 13MB per photo, you can see how local storage can be impacted in a matter of months. This makes cloud an obvious and relevant option to prevent exhausting local storage. In fact, we think cloud will be even more disruptive in the wake of UHD – but why should Apple be the only one that offers it?

UHD goes beyond phones, to set top boxes and storage devices. As the availability of UHD technology infiltrates film production, users can experience better color, frame rates and the authenticity of film that was captured in UHD. Those vivid, additional pixels take up a lot of storage. How much local storage will a set top box need? 500 GBs suddenly sounds pretty small if you regularly use your DVR to record movies and TV shows to watch at another time.

While content is currently limited, the higher quality files will inevitably become the standard. This will squeeze local device storage even more. The cloud is the only answer. And Bitcasa is seeing this realization across the entire device economy.

FCC Stirring it up in 2016

The FCC is stirring up the set-top-box industry, with a proposal requiring cable companies to welcome  competing devices with open arms.

The industry is heating up with consumers driving the desire for access to both digital video broadcasting and Internet  content from any device, any time. With the emergence of 4K , users will expect an enhanced viewing experience and interactive services.  All of these trends will drive innovation, demand for cloud storage, and the ability to deliver customized user-experiences.

We’ve seen the trend with strategic partnerships in 2015: Arris and Tivo,  Technicolor and Cisco, and Samsung and Telefonica to name a few.

Let’s see how the FCC votes on February 18th.
