Researchers at the University of California San Diego (UCSD) have found a way to track a phone based on its Bluetooth signal. Scientists have focused on devices using Bluetooth Low Energy (BLE). This technology was designed to reduce the power consumption of traditional Bluteooth at the expense of low bandwidth and low range. BLE uses only 1% of the power required for traditional Bluetooth. This allows BLE-enabled devices to stream continuously.
Instead of trying to break the encryption of the data within the signal, the researchers focused on identifying the unique characteristics of the broadcast radio signal. All wireless transmitters have signal interference that is unique to each device. This interference is carried through the signal and can be isolated from the data, creating a unique marker (or digital fingerprint).
The researchers found that the rate of false positive and false negative results with this method was less than 5%. And on some devices, such as the Pixel 5, the false negative rate was 0%. This means that there has never been a single case where a digital fingerprint was incorrectly identified.
At the same time, shortcomings were immediately announced that do not allow the full use of this tracking method. Some BLE chipsets have similar interference, making identification much more difficult. In addition, digital fingerprints can vary with temperature, limiting the exploitation of this vulnerability.
If you are still worried about this vulnerability, then you just need to turn off Bluetooth when you do not need it.
Official: Huawei will unveil its second car on July 4th. Hybrid Aito M7 debuts on the same day as nova 10 smartphones
Previously, Huawei announced that the official premiere of the nova 10 series smartphones would take place on July 4, and now it has become known that the company will also introduce its second car, the Aito M7, on the same day. With one shot, Huawei will kill two birds with one stone, however, they say that this day there will be much more new products.
Aito M7 is a hybrid crossover. In terms of dimensions, it will be noticeably larger than Huawei’s first car, the Aito M5 hybrid crossover. The company has released several new teasers that suggest the Aito M7 will be positioned as a large family travel car.
Official details will be revealed on July 4, but it is already known that the car is designed for six, and its dimensions are 5020 x 1945 x 1775 mm with a wheelbase of 2820 mm.
The capacity of the traction battery will be approximately 40 kWh – on pure electricity, the crossover will be able to travel about 150 km, and the average fuel consumption will be about 7 liters per 100 km. There will be no lack of power: a 177 hp electric motor mounted on the front axle will be combined with a 272 hp engine. on the rear axle.
Samsung Galaxy S23 smartphones are unlikely to receive a sub-screen front camera
Samsung is not considering adding under-screen front cameras to the Galaxy S23 line of smartphones. They were not in the Galaxy S22 either. This is stated on the Korean site Naver. A user under the pseudonym Ianzuk, citing sources in the supply chain, claims that Samsung does not have much confidence in the quality of this technology.
The source believes that the under-screen cameras do not yet match the quality of conventional front cameras. ZTE and Xiaomi also had similar problems. They also experimented with under-screen solutions, but failed to solve all the problems.
Even with the $1,799 Samsung Galaxy Z Fold 3, the quality of selfie shots was lower than with a regular camera. Therefore, according to the source, Samsung will not release a premium line with such cameras.
It was previously reported that the front cameras in the Galaxy S23 will receive more powerful image sensors with a resolution of 12 megapixels. And these smartphones are credited with the main camera with a resolution of 200 megapixels.
