The Beauty of Blockchains

A rainbow of color blocks.Last year I wrote about the Bitcoin revolution and some of the implications to our financial, currency, and trading systems. At that time, a single Bitcoin was worth $1,100 but now is only worth $379. There are wild price swings and talk of dissent among Bitcoin developers, as outlined in a recent Wall Street Journal article. Whether Bitcoin or some other crypto-currency survives in the long run, I think the most interesting story is the blockchain technology behind the rise of Bitcoin and the wide-ranging uses for this development.

Blockchain Explained

A blockchain can best be described as a ledger or database that exists simultaneously on hundreds or even thousands of systems. All of these copies are cryptographically connected to ensure data security.

In the case of a Bitcoin, every time a coin or a fraction of a coin is used, that transaction is recorded on the ledger. The database or registry records who had the coin and who now has the coin, which prevents a coin holder from spending the same coin multiple times. Because this registry is replicated in several identical databases simultaneously, someone attempting to hack into a system to steal the coin would have to hack into all of the systems at the same time. Changing only one instance of the registry alerts the other systems of the fraud and blocks the transaction. If blockchains can be used for currency, what are other possible uses for this technology?

Title Chains

Anything that requires a title could make use of blockchains. When you purchase a home or a vehicle, you need to know the person selling that property really owns it. A title tracks ownership through the life of the property. When you purchase the property, you are added to the title. This process takes a lot of resources, both human and computer, and is not immune to fraud.

When I sold stock, I had to send my paper certificate to a broker to prove that I was indeed the owner. When I bought stock, the broker sent me a newly issued certificate to prove that I was the owner. Now the exchange is executed electronically, but it can still take up to three days to complete a transaction because of all of the systems and humans involved in the process. All of these transactions could be simplified by secure blockchain technology, which would be quicker and would reduce risk and amount of paperwork.

Developing Countries

I think that developing countries could benefit greatly by using blockchain technology. Many of them do not have a secure title transfer infrastructure which limits their ability to buy and sell goods and services. Blockchains can be registered in small increments, even cents, so they can be used by entrepreneurs wanting to sell locally and worldwide without employing costly brokers.

Thinking on a larger scale, if an entrepreneur wanted to start a company, they could sell fractional shares in the company with each share secured by a blockchain transaction. The computing infrastructure does not need to reside in the community or even in the country but could be anywhere in the world. The transaction costs can be a lot lower, thus ensuring that more of the profit is kept in the community and reinvested for future growth and opportunities.

Thoughts

I am excited by the fact that technologies such as blockchains can create new opportunities. Coupled with other emerging advances, such as green power and wireless communications, this has the potential to be a game changer. Let me know your thoughts.

Advances in Wellness: Improving the Quantified Self

Conceptual image of a running man and his heart rate.New medical products and apps introduced at the recent Consumer Electronic Show Digital Health Summit (CES) present a lot of promise for keeping us healthy and safe. Often overshadowed by tech gadgets such as new cars and new artificial intelligence products, it’s time to give the medical developments their day in the sun.

Pathway Genomics OME

The Pathway OME app is powered by IBM Watson and is a comprehensive app that collects personal health information from a variety of sources including electronic health records, data from health monitoring devices, and even a DNA sample. From this data, the app will give you advice or alert you to potential health issues. Through the IBM Watson’s data intelligence power you can receive personalized information on potential interactions with food and drugs or receive a custom diet and exercise regimen.

Wisewear

Who says that health and safety monitoring can’t be fashionable? Wisewear makes a fashion bracelet that monitors vital statistics and acts as an emergency beacon. When you think you are in danger or need help, tap the stylish bracelet three times and it will connect with your phone to send out text alerts, including your location, to friends. This is a great marriage of form and function.

Quell

Neurometrix makes a pain management device that is drug free and monitors and counteracts chronic pain 24/7. This is an electrode that is worn on the upper calf just below the knee and delivers a signal that blocks pain neurotransmitters throughout the body. It counteracts pain from arthritis and other musculoskeletal issues and allows the wearer to enjoy work and activities. It synchs with a smartphone app to deliver a profile of your pain management. It is adjustable and easily rechargeable. My father used to connect leads to a voltage generator to help ease his arthritis pain. I realize now that he was just ahead of his time, although maybe his system was not quite as elegant.

Mimo

The Mimo Smart Baby Monitor uses very low voltage sensors built into a baby sleeper to deliver information about breathing, movement, and sleep/wake patterns to a smartphone app. This, in theory, lowers stress for new parents and allows them to sleep better. The same information is also available to other smartphones if a parent has to be out of town but still wants to track their baby. Definitely a quantified life right from day one.

Resound

Enzo hearing aids from Resound combine advanced technology with a sophisticated smartphone app that lets you fine tune your hearing to different conditions. Whether you find yourself in a crowded noisy room or in a quiet place trying to hear a soft voice, the app lets you discreetly adjust your hearing aids. You can also couple them to your smartphone to listen to music or voice directly through your hearing aids.

Thoughts

The health technologies displayed at CES this year are designed to help us be active, healthy, and safe and provide the capability to monitor and assist those we love.

Did you see any extraordinary products at CES this year? Let me know what caught your eye.

Clearing the Decks in the New Year

Ship sailing through rough seas from perspective of the deck.Clear The Decks

I recently came across the term “clear the decks” and it sums up well my thoughts as I begin a new year. Clear the decks is a nautical term used to warn the sailing crew to remove or secure all loose objects that might get in the way of the guns or injure the crew. It is a way of saying prepare for battle or prepare for a new adventure. The new year represents new opportunities, so why not clear the deck of anything that might get in the way? Here are some ways that I will prepare for the future.

Clearing Stuff

I have accumulated a lot of stuff over the years and occasionally I need to reduce. Last year I sold one of my motorcycles and one of my bicycles. I was surprised that getting rid of some of my stuff gave me a new perspective and fresh energy for new projects, not to mention creating room in my garage. I am also trying to clear out papers and books that I no longer need or read. Being free of this unneeded material lets me focus on things that are important to me. I still have more stuff to reduce in 2016 but this was a good beginning.

Fresh Thinking

Sometimes new learning can give me a spark to start new projects or complete old ones. I recently began a new MOOC on statistical thinking for data science. This is the first of a series of three courses which I chose to expand my thinking on some of my work. Since it is applied learning, I am gleaning new ideas that I can use immediately. Whether it is a short course such as this series of MOOCs or something as extensive as pursuing a new degree, education is a great way to clear the decks and may lead you in a new direction.

New Relationships

Another way to jump start the new year is to evaluate your network to determine who can help you in your upcoming adventures and whom you can help in return. A purposeful evaluation of your network will help you determine how you can make progress on the things that matter to you. Is it time to find a mentor? Do you need to let go of old relationships that hold you back? Conversely, is there someone out there who needs your experience and expertise?

Thoughts

Our calendar is handed down from ancient Caesers and popes and provides no magic when we turn the page to a new day or month or year. The magic and each beginning comes from us. It comes from our planning to make the next day and the next year even better than the last. One way we can do that is to clear the deck of anything holding us back as we get ready for the next journey.

Beyond Passwords: The New Face of Authentication

Black and white drawing of two fingerprints.When the Heartbleed bug was discovered in April 2015 it cast a light on the problem of password vulnerabilities. Since then, or even before, IT departments have increased password requirements for both administrators and end users. Some organizations now require passwords of 13 characters or more that must contain certain combinations of letters, numbers and symbols, and must be refreshed as often as every six weeks. These requirements have led frustrated users to reuse the same password over multiple accounts or to write down the password and keep it in a supposed safe place. The increased vigilance is causing behavior that leads to less secure systems and accounts. What is the answer? Bill Gates declared the password dead in 2004 but they are still very much alive in 2016. For this blog post I set out to find acceptable alternatives to this problem.

Two Factor Authentication

While double identification does not remove the need for a password, it does make an account more secure. This is an option available now for Twitter and other accounts and can be set up in your profile. With this system, you enter the standard password and then enter a separate six digit code that is sent to your smartphone at the time of log in. It is a step towards more secure accounts and systems.

Cryptography

Google takes two factor authentication one step further with a device that uses public key cryptography. This is a small USB device that provides a second authentication for Google apps, Gmail, Dropbox, and other applications. You plug the device into a computer to verify your identity. Near field communication or low power Bluetooth will be used soon to eliminate the physical connection.

Biometrics

Apple and Samsung are adding biometric authentication to their newest smartphones and tablets. This eliminates passwords completely by identifying you from your fingerprint. It is as easy as placing your finger or thumb on the screen before unlocking your phone or apps and would keep a lost or stolen smartphone secure.

The Myris portable retinal scanner from Eyelock allows you to log in to websites and applications via a quick retinal scan. Once you establish an image of your retina through video capture, you simply glance into the USB device to gain access to applications.

The Nymi heartbeat scanner is in development now and is another way to authenticate users via biometrics. This is a bracelet that records your heartbeat and then uses that to identify you to systems such as computers, door locks, and retail computers that would normally require a PIN or password. The software developer kit is available now and the product will be out soon.

All of these are attempts to easily identify an individual by a unique pattern and not by a password they carry around in their head (or wallet). The next logical step would be to present DNA, but I am not sure yet how that can be captured.

Thoughts

Bill Gates may have been premature in declaring the password dead but I hope that he is on the right track. I struggle to remember all of my logins and passwords and I could use help. Have you found a reliable and safe alternative to passwords? Do you use or trust biometrics? Let me know your thoughts so that I can start using the password portion of my brain for better things.
