The Future of Security is Biometric
With nearly eight billion people on the planet — and more than half of them on internet — verifying who’s who is one of the great technological challenges of our time. To meet this challenge, Biometric security is rising to the occasion, buoyed by technological advancements and user-friendly experiences.
Modern biometrics can seem like science fiction, but the concept is far from new. Sir Francis Galton, cousin of the famous Charles Darwin, used an analysis of over 8,000 fingerprint samples to publish what would become the first fingerprint classification system in history.
Building on the work of Sir Francis Galton, the Metropolitan Police of London used shapes like whorls and loops identify individuals based on fingerprint patterns at the beginning of the 20th century. The resulting Henry Classification System is so effective, it’s still the foundation for the most common form of biometrics used around the world today – the Automated Fingerprint Identification System (AFIS).
Today’s infographic, from Computer Science Zone, covers biometric security from a number of angles, from current use cases to the ways people are outsmarting existing security measures.
Biometric Security 101
There are three possible ways of proving one’s identity:
- Using something you possess (e.g. keys, badge, documentation)
- Using something you know (e.g. password, code, security question)
- Using an intrinsic identifying feature (e.g. fingerprint, face)
Biometrics are an example of the third type, using biological measurements to identify individuals. Typically, these measurements are derived from physical characteristics, such as irises, fingerprints, facial features, or even a person’s voice.
When used in a security application, biometrics are theoretically more secure than traditional passwords since detailed physical characteristics are unique to each person.
By now, we’re all well aware that solely using text passwords leaves our information at risk. Even in 2019, the top passwords are still “123456” and “password”.
Passwords are still the default method of accessing accounts though, so a process called two-factor authentication was introduced to add a new layer of security. The most common type of two-factor authentication involves sending an email or text message to help ensure that only the rightful owner of an account can log in.
Increasingly though, biometric security measures are replacing one or both of those steps. Apple’s introduction of a fingerprint scanner in the iPhone 5S was a high-profile example of biometrics moving into widely available consumer products. Today, every new smartphone on the market has some sort of biometric feature.
The Internet of Faces
Today, the majority of consumers are now comfortable with using fingerprint recognition to access their device, but they’re still skeptical about facial recognition — only 14% of people prefer using that method to access their device.
Soon, however, they may not have a choice. Consumer technology is bullish on facial recognition, and government entities are happy to come along for the ride. Correctly and efficiently identifying citizens has always proved a struggle for law enforcement, border control, airport security, and other highly regulated systems, so facial recognition is a very appealing option to quickly and cheaply identify people at scale.
One real world example is the Schengen Entry-Exit System, which will use a mix of fingerprint and facial recognition to alleviate security bottlenecks at European airports.
In China, a new rule that went into effect across the country making the submission of facial recognition scans a prerequisite for registering a new SIM card — just one of the ways China is populating its biometric database.
Of course, the trade-off is a loss of privacy as that technology spills over from airport security into public spaces.
According to a recent study, facial recognition accuracy jumped 20x between 2013 and 2018. Just 0.2% of searches, in a database of of over 26 million photos, failed to match the correct image.
Peering into the Digital Reflection
Another aspect of biometric security looks beyond physical features, and instead relies on changes in behavioral patterns to detect fraud or unauthorized access.
Money laundering and fraud cost the global economy upwards of $2 trillion per year, so financial institutions in particular have a big incentive to invest in early fraud detection. To this end, behavioral biometrics is proving to be an effective way of detecting suspicious login attempts earlier and flagging transfers that deviate from expected patterns.
Biometric security in consumer products is still in its early stages, so the technology is far from bulletproof. There have been several examples of fooling systems, from fingerprint cloning to using masks to unlock devices. As with any security measure, there will continue to an arms race between companies and hackers looking to slip past defenses.
Another issue raised by increasing biometric use is in the realm of privacy. Critics of biometrics point out that iris scans and FaceID don’t enjoy the same protection from law enforcement as a traditional password. Because a defendant would have to say something, text passwords fall under the protection of the Fifth Amendment, while biometric locks do not. This is a debate that will continue to rage on as consumer products continue to implement biometrics.
In the meantime, our physical attributes will increasingly become our key to the digital world.
Visualizing the Power Consumption of Bitcoin Mining
Bitcoin mining requires significant amounts of energy, but what does this consumption look like when compared to countries and companies?
Visualizing the Power Consumption of Bitcoin Mining
Cryptocurrencies have been some of the most talked-about assets in recent months, with bitcoin and ether prices reaching record highs. These gains were driven by a flurry of announcements, including increased adoption by businesses and institutions.
Lesser known, however, is just how much electricity is required to power the Bitcoin network. To put this into perspective, we’ve used data from the University of Cambridge’s Bitcoin Electricity Consumption Index (CBECI) to compare Bitcoin’s power consumption with a variety of countries and companies.
Why Does Bitcoin Mining Require So Much Power?
When people mine bitcoins, what they’re really doing is updating the ledger of Bitcoin transactions, also known as the blockchain. This requires them to solve numerical puzzles which have a 64-digit hexadecimal solution known as a hash.
Miners may be rewarded with bitcoins, but only if they arrive at the solution before others. It is for this reason that Bitcoin mining facilities—warehouses filled with computers—have been popping up around the world.
These facilities enable miners to scale up their hashrate, also known as the number of hashes produced each second. A higher hashrate requires greater amounts of electricity, and in some cases can even overload local infrastructure.
Putting Bitcoin’s Power Consumption Into Perspective
On March 18, 2021, the annual power consumption of the Bitcoin network was estimated to be 129 terawatt-hours (TWh). Here’s how this number compares to a selection of countries, companies, and more.
|Name||Population||Annual Electricity Consumption (TWh)|
|All of the world’s data centers||-||205|
|State of New York||19.3M||161|
|Walt Disney World Resort (Florida)||-||1|
Note: A terawatt hour (TWh) is a measure of electricity that represents 1 trillion watts sustained for one hour.

If Bitcoin were a country, it would rank 29th out of a theoretical 196, narrowly exceeding Norway’s consumption of 124 TWh. When compared to larger countries like the U.S. (3,989 TWh) and China (6,543 TWh), the cryptocurrency’s energy consumption is relatively light.
For further comparison, the Bitcoin network consumes 1,708% more electricity than Google, but 39% less than all of the world’s data centers—together, these represent over 2 trillion gigabytes of storage.
Where Does This Energy Come From?
In a 2020 report by the University of Cambridge, researchers found that 76% of cryptominers rely on some degree of renewable energy to power their operations. There’s still room for improvement, though, as renewables account for just 39% of cryptomining’s total energy consumption.
Here’s how the share of cryptominers that use each energy type vary across four global regions.

and the Caribbean

Editor’s note: Numbers in each column are not meant to add to 100%
Hydroelectric energy is the most common source globally, and it gets used by at least 60% of cryptominers across all four regions. Other types of clean energy such as wind and solar appear to be less popular.
Coal energy plays a significant role in the Asia-Pacific region, and was the only source to match hydroelectricity in terms of usage. This can be largely attributed to China, which is currently the world’s largest consumer of coal.
Researchers from the University of Cambridge noted that they weren’t surprised by these findings, as the Chinese government’s strategy to ensure energy self-sufficiency has led to an oversupply of both hydroelectric and coal power plants.
Towards a Greener Crypto Future
As cryptocurrencies move further into the mainstream, it’s likely that governments and other regulators will turn their attention to the industry’s carbon footprint. This isn’t necessarily a bad thing, however.
Mike Colyer, CEO of Foundry, a blockchain financing provider, believes that cryptomining can support the global transition to renewable energy. More specifically, he believes that clustering cryptomining facilities near renewable energy projects can mitigate a common issue: an oversupply of electricity.
“It allows for a faster payback on solar projects or wind projects… because they would [otherwise] produce too much energy for the grid in that area”
– Mike Colyer, CEO, Foundry
This type of thinking appears to be taking hold in China as well. In April 2020, Ya’an, a city located in China’s Sichuan province, issued a public guidance encouraging blockchain firms to take advantage of its excess hydroelectricity.
Which Streaming Service Has the Most Subscriptions?
From Netflix and Disney+ to Spotify and Apple Music, we rank the streaming services with the most monthly paid subscriptions.
Which Streaming Service Has The Most Subscriptions?
Many companies have launched a streaming service over the past few years, trying to capitalize on the digital media shift and launching the so-called “streaming wars.”
After Netflix grew from a small DVD-rental company to a household name, every media company from Disney to Apple saw recurring revenues ripe for the taking. Likewise, the audio industry has long-since accepted Spotify’s rise to prominence, as streaming has become the de facto method of consumption for many.
But it was actually the unexpected COVID-19 pandemic that solidified the foothold of digital streaming, with subscription services seeing massive growth over the last year. Although it was expected that many new services would flounder along the way, media subscription services saw wide scale growth and adoption almost across the board.
We’ve taken the video, audio, and news subscription services with 5+ million subscribers to see who came out on top—and who has grown the most quickly—over the past year. Data comes from the FIPP media association as well as individual company reports.
Streaming Service Giants: Netflix and Amazon
The top of the streaming giant pantheon highlights two staples of business: the first-mover advantage and the power of conglomeration.
With 200+ million global subscribers, Netflix has capitalized on its position as the first and primary name in digital video streaming. Though its consumer base in the Americas has begun to plateau, the company’s growth in reach (190+ countries) and content (70+ original movies slated for 2021) has put it more than 50 million subscribers ahead of its closest competition.
The story is the same in the audio market, where Spotify’s 144 million subscriber base is more than double that of Apple Music, the next closest competitor with 68 million subscribers.
Meanwhile, Amazon’s position as the second most popular video streaming service with 150 million subscribers might be surprising. However, Prime Video subscriptions are included with membership to Amazon Prime, which saw massive growth in usage during the pandemic.
|Service||Type||Subscribers (Q4 2020)|
|Amazon Prime Video||Video||150.0M|
|Amazon Prime Music||Audio||55.0M|
|Tencent Music (Group)||Audio||51.7M|
|New York Times||News||6.1M|
Another standout is the number of large streaming services based in Asia. China-based Tencent Video (also known as WeTV) and Baidu’s iQIYI streaming services both crossed 100 million paid subscribers, with Alibaba’s Youku not far behind with 90 million.
Disney Leads in Streaming Growth
But perhaps most notable of all is Disney’s rapid ascension to the upper echelons of streaming service giants.
Despite Disney+ launching in late 2019 with a somewhat lackluster content library (only one original series with one episode at launch), it has quickly rocketed both in terms of content and its subscriber base. With almost 95 million subscribers, it has amassed more subscribers in just over one year than Disney expected it could reach by 2024.
|Service||Type||Percentage Growth (2019)|
|Amazon Prime Video||Video||100.0%|
|Amazon Prime Music||Audio||71.9%|
|Tencent Music (Group)||Audio||66.8%|
|New York Times||News||60.5%|
The Disney+ wave also spurred growth in partner streaming services like Hotstar and ESPN+, while other services with smaller subscriber bases saw large growth rates thanks to the COVID-19 pandemic.
The lingering question is how the landscape will look when the pandemic starts to wind down, and when all the new players are accounted for. NBCUniversal’s Peacock, for example, has reached over 30 million subscribers as of January 2021, but the company hasn’t yet disclosed how many are paid subscribers.
Likewise, competitors are investing in content libraries to try and make up ground on Netflix and Disney. HBO Max is slated to start launching internationally in June 2021, and ViacomCBS rebranded and expanded CBS All Access into Paramount+.
And international growth is vital. Three of the top six video streaming services by subscribers are based in China, while Indian services Hotstar, ALTBalaji, and Eros Now all saw surges in subscriber bases, with more room left to grow.
