Bluetooth-enabled technology will empower the future of hearing
The recent World Hearing Day gave us the opportunity to raise awareness and shed light on the reasons why hearing loss is a pressing, far-reaching problem that needs decisive measures. Over 5% of the world’s population, which roughly constitutes 466 million people, is affected by hearing loss. Furthermore, according to the charity Action on Hearing Loss, one-fifth of the UK society will struggle with this problem by 2035.

Apple and Google’s COVID-19 Exposure Notification API: Questions and Answers
Apple and Google are undertaking an unprecedented team effort to build a system for Androids and iPhones to interoperate in the name of technology-assisted COVID-19 contact tracing. The companies’ plan is part of a torrent of proposals to use Bluetooth signal strength to enhance manual contact tracing with proximity-based mobile apps. As Apple and Google are an effective duopoly in the mobile operating system space, their plan carries special weight.

Coronavirus contact-tracing apps a good idea — if ‘done correctly’: Canadian cybersecurity expert
They say there’s an app for everything, but does that include contact tracing for the coronavirus? According to digital security expert Ritesh Kotak, it’s a good idea, as long as it’s implemented properly. “As these restrictions start to get looser and people start to travel from province to province again, we’re going to need better data to be aggregated and talk to each other,” Kotak — a tech industry consultant who has helped develop cybercrime prevention strategies for police forces across Canada and internationally — told 680 CJOB.

iOS 13.5 Beta 3 Has Toggle to Enable COVID-19 Exposure Notifications, Skips Face ID When Wearing Mask
The new iOS 13.5 beta seeded to developers today includes a toggle that allows testers to enable COVID-19 exposure notifications. Here’s what happens when you toggle the feature on: Once enabled, users’ devices will regularly send out a beacon via Bluetooth that
includes a privacy-preserving identifier — basically, a string of random numbers that aren’t tied
to a user’s identity and change every 10-20 minutes for additional protection.

How Apple and Google will let your phone warn you if you’ve been exposed to the coronavirus
On April 10, Apple and Google announced a coronavirus exposure notification system that will be built into their smartphone operating systems, iOS and Android. The system uses the ubiquitous Bluetooth short-range wireless communication technology. There are dozens of apps being developed around the world that alert people if they’ve been exposed to a person who has tested positive for COVID-19.

What Apple And Google Need To Do To Make Contact Tracing Trustworthy
Apple and Google have announced that they are partnering on a new set of APIs to allow contact tracing to be an embedded aspect of their operating systems, rather than relying on an app to perform contact tracing. The information that has been released so far reveals a huge emphasis on the privacy-protecting anonymization of the data collected by the system, but my concern is the complete lack of any information on how they intend to do the most important part well – use Bluetooth (BLE) measurements for high-performance contact tracing.

Contact tracing apps unsafe if Bluetooth vulnerabilities not fixed
As more governments turn to contact tracing apps to aid in their efforts to contain the coronavirus outbreak, cybersecurity experts are warning this may spark renewed interest in Bluetooth attacks. They urge developers to ensure such apps are regularly tested for vulnerabilities and release patches swiftly to plug potential holes, while governments should provide assurance that their databases are secure and the data collected will not be used for purposes other than as originally intended.

LDAC, aptX, AAC… What’s the best Bluetooth audio codec?
Wireless audio is clearly the future. As manufacturers kill off the 3.5mm headphone jack and continue to flood the market with Bluetooth headphones and true wireless earbuds, one phrase keeps cropping up in reviews – Bluetooth audio codecs. But what does this technical specification actually mean? What’s the best codec for audio quality and connection stability? Allow us to explain.

Encryption system for a secure contact tracing app
In the fight against Covid-19, an interdisciplinary research team at the Technical University of Munich (TUM) has developed a model for a contact tracing app that protects personal data. The concept is based on an encryption process that prevents the temporary contact numbers (TCNs) of infected individuals from ending up on the phones of their contacts. A prototype is now undergoing testing in cooperation with the ITO Open Source Consortium. The app has also successfully completed the Bluetooth Special Interest Group qualification process.
