Add to the list of known certainties: death, taxes, and the need to lower the cost of healthcare.
Neither HIPAA standards nor encryption were created with the purpose of lowering the cost of healthcare, but neither was penicillin originally purposed as an antibiotic. Both welcome side effects in the world of medicine.
Cloud Computing and Healthcare
Healthcare and medical companies are migrating to cloud computing in record numbers. The cloud offers flexibility and scalability to manage ever-growing databases of patient records. At the same time, it offers mobility to enable care providers to access patient information remotely and shareability to share data with colleagues, specialists, and labs. The cloud, perhaps most importantly, enables cost reduction on several levels.
- It eliminates the need healthcare organization have to purchase, maintain, upgrade, and replace costly computing equipment and staff.
- It saves costs of multiple providers running multiple tests by enabling them to share and track the results.
- It saves time and money by enabling paperless transmission of prescriptions and insurance claims. It also increases the accuracy of reimbursement coding.
Now, HIPAA omnibus and the American Recovery and Reinvestment Act (ARRA) requirements stipulate everyone in the healthcare industry begin migrating patient records and other data to cloud computing. Essentially, by 2015, all medical professionals with access to patient records must utilize electronic medical and health records (EMR and EHR), or face penalties.
The North American healthcare cloud computing market is expected to grow to nearly $6.5 billion by 2018.  Healthcare Financial Management recently reported that savings benefits of EMRs/EHRs can amount to upwards of $37 million over a five-year period.
These are big numbers and big savings for healthcare.
HIPAA Standards and Encryption
HIPAA advises us to encrypt our e-PHI, whether at rest or in motion, whenever it is “reasonable and appropriate” to do so. And, especially in the cloud, it is fair to say that it is always “reasonable and appropriate” to encrypt Personal Health Information.
What encryption of ePHI aims to resolve, essentially, is breaches of patient data.
And, it is succeeding!
A Ponemon Institute study recently found that healthcare data breaches declined in both number and size in 2013, which is great news because data breaches cost healthcare organizations $5.6 billion annually.
To enable organizations to both protect e-PHI and lower the overall cost of healthcare, the Secretary of Health and Human Services published guidance on “technologies and methodologies that render protected health information unusable, unreadable, or indecipherable to unauthorized individuals.” The guidance emphasizes that data encryption is not only a best practice for protecting privacy and security – it also provides a safe harbor to the organization in case of data loss.
By using accepted HIPAA encryption techniques, companies can mitigate risks and reduce their exposure to costly data breaches, thereby reducing the cost of healthcare.
Encryption Key Management for HIPAA Compliance
In the cloud, security and privacy concerns amass. Experts agree that while encryption is a critical component of a cloud security policy, it is not sufficient. To fully protect e-PHI in cloud computing scenarios, encryption keys must be managed in a way that is secure, automated, and constantly remains at the sole ownership and discretion of the covered entity or their business associate.
That is, encryption keys absolutely cannot be stored alongside encrypted data or visible to (much less, managed by) a cloud provider or other third party. An accepted best practice for encryption key management and HIPAA compliance is split key encryption with homomorphic key management.
Cloud Encryption and Cloud Key Management Lower Costs
By enabling healthcare organizations to securely enjoy the benefits of cloud computing, innovations like these reduce risk and mitigate costs associated with expensive data breaches. By enabling the covered entities to claim “safe harbor,” they also negate the possibility of additional fines, penalties, and expensive bureaucracy that can accompany a breach in the cloud.
"BSQUARE is in the business of selling software solutions for smart connected devices. It's obvious that IoT has moved from being a technology to being a fundamental part of business, and in the last 18 months people have said let's figure out how to do it and let's put some focus on it, " explained Dave Wagstaff, VP & Chief Architect, at BSQUARE Corporation, in this SYS-CON.tv interview at @ThingsExpo, held Nov 4-6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs.

Nigeria has the largest economy in Africa, at more than US$500 billion, and ranks 23rd in the world. A recent re-evaluation of Nigeria's true economic size doubled the previous estimate, and brought it well ahead of South Africa, which is a member (unlike Nigeria) of the G20 club for political as well as economic reasons. Nigeria's economy can be said to be quite diverse from one point of view, but heavily dependent on oil and gas at the same time. Oil and natural gas account for about 15% of Nigera's overall economy, but traditionally represent more than 90% of the country's exports and as...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...

We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
