Are… are our devices about to start whispering data to each other?

(TECH NEWS) Bluetooth has been around for years, but will smartphones and other devices soon use audio to transmit data?

smartphones data whispering

Wireless technology has branched off into several different avenues over the past couple of decades, with wireless Internet, cellular data, and Bluetooth all providing similar means of information delivery. Thanks to work by Lisnr, a startup based in Cincinnati, we may soon be using a new option: sound.

Principally, delivering information via sound isn’t as bizarre as it—well, sounds. Things like dial-up have been transcoding digital information into perceptible sound and then back into information since the 90s, and the practice itself most likely goes back farther than that.

More recently, the process of pairing your phone with a Chromecast device is also reliant on data-over-sound.

The key difference between dial-up and Lisnr’s approach is that, unlike the majority of past instances of information over sound, information will be transmitted over the air rather than through a hardwired connection.

This approach would make things like scanning a card at a restaurant or a pass at a venue much more efficient, as people wouldn’t have to worry about their phones failing to use properly the Bluetooth NFD feature. Similarly, the process would likely be as quick as using Bluetooth, and it might even be more ubiquitous.

Transmitting data via sound would be a relatively cost-effective solution as well, since the bulk of card readers that can handle Bluetooth also come equipped with external microphones that would allow for audio reception if given a minor set of tweaks. This means that the average business wouldn’t have to spend thousands of dollars upgrading their equipment just to meet an upcoming trend.

Two large concerns come to mind when considering this technology, the first of which is the security aspect. It’s easy to understand why people might be skeptical about sending information—encrypted or otherwise—across radio waves, though preliminary assessments concluded that transmitting data over sound is as secure as (if not more so than) using Bluetooth or Wi-Fi.

As with any emerging technology, we’ll have to see how quickly the world can respond and adapt to its nuances.

The other concern is that data-over-sound transmissions will be too simple to differentiate between different devices, but Google’s Chromecast pairing is definitive proof that this won’t be an issue – data transmission via audio has already been proven to be more accurate than Bluetooth recognition.

Audio data transmission is still a ways off, but don’t be too surprised if you find yourself paying for your meal with radio waves instead of Bluetooth in the not-too-distant future.

Google set to release new AI-operated meeting room kit… and it’s pretty baller

(TECH NEWS) Google’s newest toy is designed to “put people first” by alleviating video and audio issues for conference room meetings.

Google Meet Series One is a new meeting kit that puts people first.

Remote meetings can be the worst sometimes. The awful video and audio quality are frustrating when you’re trying to hear important details for an upcoming project. Even with the fastest internet connection, this doesn’t guarantee you’ll be able to clearly hear or see anyone who’s in the office. But Google is re-imagining conference rooms with their new video conferencing hardware.

Yesterday, the company introduced Google Meet Series One. In partnership with Lenovo, this meeting room kit is made exclusively for Google Meet and is poised to be the hardware that “puts people first.”

The Series One has several components that make it stand out. First is the “Smart Audio Bar,” powered by eight beam-forming microphones. Using Google Edge TPUs, the soundbar can deliver TrueVoice®, the company’s “proprietary, multi-channel noise cancellation technology.” It removes distracting sounds, like annoying finger and foot-tapping noises, so everyone’s voices are crystal clear from anywhere in the room.

The hardware also has 4K smart cameras that allow for high-resolution video and digital PTZ (pan, tilt, zoom) effects. Processed with Google AI, the device knows to automatically zoom in and out so all of the meetings’ participants are framed in the camera. With an i7 processor and Google Edge TPUs, the system is built to “handle the taxing demands of video conferencing along with running the latest in Google AI as efficiently and reliably as possible.”

The meeting kit has Google grade security built-in, so the system automatically updates over-the-air. The system also works seamlessly with Google services and apps we already use. Its touch control display is powered by a single ethernet cable. From the admin controls, you can manage meeting lists and control room settings. Powered by assistant voice commands, their touch controller provides a “touchless touchability”; if you want to, you can join a meeting just by saying, “Hey Google, join the meeting.”

These new meeting kits are easy to install and are versatile. They can be configured to fit small, medium, and large-sized rooms. “Expanding kits for larger rooms can be done with just an ethernet cable and the tappable Mic Pod, which expands microphone reach and allows for mute/unmute control.”

According to the Google Meet Series One introductory video, the meeting room kits are “beautifully and thoughtfully designed to make video meetings approachable and immersive so everyone gets a seat at the table.”

Currently, there is no release date set for Google Meet Series One. However, pre-orders will soon be available in the US, Canada, Finland, France, Norway, Spain, Ireland, United Kingdom, Sweden, Australia, New Zealand, Japan, Netherlands, Denmark, and Belgium.

One creepy way law enforcement might have your private data

(TECH NEWS) Wait, geofences do what? Law enforcement can pull your private data if you’re in the wrong place at the wrong time.

Published

Man walking on crosswalk with phone, but his private data could be vulnerable.

By now, it’s pretty common knowledge that our smartphones are tracking us, but what you might not be aware of is just how much law enforcement is taking advantage of our private data. Now, the good news is that some places have gotten wise to this breach of privacy and are banning certain tactics. The bad news is: If you were ever in the vicinity of a recent crime scene, it’s quite possible your privacy has already been invaded.

How are law enforcement doing this? Well, it starts with a geofence.

At its core, a geofence is a virtual border around a real geographic location. This can serve many purposes, from creating marketing opportunities for targeted ads to tracking shipping packages. In the case of law enforcement, though, geofences are often used in something called a geofence warrant.

Traditionally, warrants identify a subject first, then retrieve their electronic records. A geofence warrant, on the other hand, identifies a time and place and pulls electronic data from that area. If you’re thinking “hey, that sounds sketchy,” you are–forgive the pun–completely warranted.

With a geofence, law enforcement can dig through your private data, not because they have proof you were involved in a crime, but because you happened to be nearby.

This practice, though relatively new, is on the rise: Google reported a 15-fold increase in geofence warrant requests between 2017 and 2018. As well as invading privacy, these warrants have led to false arrests and can be used against peaceful protesters. Not to mention, in many cases, geofence warrants can be extremely easy to acquire. One report in Minnesota found judges signed off on these cases in under 4 minutes.

Thankfully, there have been signs of people pushing back against the use of geofence warrants. In fact, there have been multiple federal court rulings that find the practice in violation of the Fourth Amendment, which protects citizens from “unreasonable searches and seizures,” including your electronic data.

If you’re still worried about your privacy, there are ways to keep your electronic data on lock. For example, turn off your location services when you’re traveling, and avoid connecting to open Wi-Fi networks. You can also work to limit location sharing with apps and websites.

These and other tips can be a great way to help you avoid not just geofence warrants, but others who want to use your electronic information for their own gain.

Incoming! Amazon drones will be dropping off packages soon (we hope)

(TECH NEWS) The Federal Aviation Administration has approved Amazon for drone delivery service, but when will the drones actually take flight?

Published

One of Prime Air's drones ready for test flights.

Amazon has finally received the stamp of approval from the Federal Aviation Administration (FAA) to deliver packages by drones. This pivotal step brings the online retailer closer to their promise of delivering packages to customers in 30 minutes or less.

In 2013, during CBS’s “60 Minutes” interview, Amazon CEO and Founder, Jeff Bezos, said drones would be delivering customers’ packages within five years. Although the estimate is a couple of years off, it seems like that day might be right around the corner.

Personally, I’m looking forward to the day when little floating presents are sailing through the sky (Animal Crossing balloons, anyone?). Despite our excitement to see our latest Amazon impulse purchase land on our doorstep, it isn’t going to happen overnight.

The Part 135 Air Carrier Certificate Amazon obtained for its fleet of Prime Air drones will allow the company to use unmanned aircraft systems (UAS) “to carry the property of another for compensation beyond visual line of sight.” Although the FAA certification is allowing Amazon to begin test trials, Bloomberg reports that the retail giant still has “regulatory and technical hurdles” to overcome.

In addition, the FAA has yet to set regulations that will “serve as a framework to expand drone flights over crowds, a building block necessary for deliveries.” Amazon hasn’t said when and where it will start testing the delivery service either.

David Carbon, Amazon Vice President who oversees Prime Air, made this statement: “This certification is an important step forward for Prime Air and indicates the FAA’s confidence in Amazon’s operating and safety procedures for an autonomous drone delivery service that will one day deliver packages to our customers around the world.”

This approval is definitely a step forward, but Amazon has been working on the drone delivery service for years. Early last year, the giant retailer revealed they would start offering one-day shipping. They have followed through on this, at least. And during a Las Vegas Conference in June 2019, they revealed their “fully electric drones that can fly up to 15 miles and deliver packages under five pounds to customers in less than 30 minutes.” But it still doesn’t answer when we can expect to see whizzing drones overhead.

I’m not sure when Amazon will fulfill their last promise. But it is getting closer. What I do know is that I look forward to the Amazon drones taking flight. I can’t wait to place my orders knowing that I will get that last-minute present I ordered just in time.
