The “Internet-of-Things” (IoT) might sound like a vague, opaque term, but that’s exactly the point for this exploding industry. In its simplest form, the Internet-of-Things is a generalized term for technology that enables one smart device to communicate with another.

Originally dedicated to making tech like phones and fitness trackers “smart,” the IoT industry has developed to the point where it can elevate even mundane household items to another level. There are currently IoT-enabled fitness trackers for your dog’s collar, smart toasters that let you know when your food has been thoroughly toasted and even smart mirrors that display on-demand workouts and show fitness statistics.

Cybersecurity Concerns in IoT

Cybersecurity Concerns in IoT

As the Internet-of-Things expands, so too do the concerns for data integrity and individual privacy. Several logical vulnerabilities in IoT devices can figuratively, and sometimes literally, open doors for cybercriminals. Hackers are able to take advantage of easy passwords, exposed IP addresses and public serial numbers that allow a criminal to take full advantage of any device.

There have been dozens of nightmarish cases reported due to the current lackluster IoT cybersecurity protocols. In one instance, hackers gained access to the camera of a baby monitor and were able to see and listen to everything going on within range. Another cybersecurity mishap occurred when a casino’s high-roller database was compromised through the hacking of a smart thermometer in the hotel’s aquarium.  

With more than 8.4 billion connected devices worldwide, the IoT industry could use a serious cybersecurity overhaul. Blockchain might be the answer to this dire need.


Benefits of Blockchain in IoT

Benefits of Blockchain in IoT

One of the most attractive characteristics of blockchain, in any industry, is its ability to secure data and thwart cyber attacks. Blockchain is a Distributed Ledger Technology (DLT) that is transparent but completely encrypted.

A blockchain is comprised of small amounts of data that is locked down with encryptions. When these “blocks” are “chained” together, members (or nodes) of the specific blockchain can easily view all data. For example, a retail company can store the credit card information of 50 of its customers in one block. The information is chained together to give the only the store a bigger-picture look at purchases. Instead of a potential hacking of the data of millions from a central database, blockchain’s decentralized chains help to keep the security risks to an absolute minimum by parceling off information.

Any changes to a blockchain are also made transparent. Each member on a chain is given a unique code that personally identifies them, but the name behind the code is not released. However, all nodes are able to see any new additions to the chain and can pinpoint malicious behavior by a specific code to quickly thwart cyber attacks.  

The main security advantage of a decentralized ledger is that if hackers somehow enter a chain, they're able to receive only a miniscule amount of data before the other nodes on the chain realize there has been a breach. Combining this decentralized security system with a transparent ledger gives blockchain the upper-hand in cybersecurity.

Blockchain can also make the IoT industry faster. With a peer-to-peer model, making payments and executing contracts are easier. Blockchain-based smart contracts eliminate the need for a third-party and approve or disapprove of an agreement almost immediately, saving countless hours and millions of dollars each year.

Distributed Ledger Technology has the potential to give the IoT industry — from fitness trackers to smart cities — the boost it needs to become a trillion dollar industry.
