Samsung files new patent application for 3D displays.

Upping the ante in the camera department, South Korean tech giant Samsung on Tuesday brought Galaxy A9, its first smartphone with quadruple primary (rear) camera system, to India.

This is the world’s first device with quad camera system at the rear and the first from the company to feature dual tone, reflective gradient design.

The 6GB RAM and 8GB RAM variants of Galaxy A9 cost Rs 36,990 and Rs 39,990, respectively.

“Our final launch of the year has brought out four-camera phone to India,” Asim Warsi, Global Vice President, Samsung India, told reporters here.

Samsung has already launched a three-camera Galaxy A7 in the country.

Prospective buyers can pre-book the smartphone starting Thursday. The device will be available across all channels starting November 28.

A major highlight of the device is its vertically-stacked four cameras consisting of an 8MP ultra-wide sensor, a 24MP main sensor, a 5MP depth sensor and a 10MP telephoto sensor at the back.

On the front, the smartphone features a 24MP camera.

There’s a rear-mounted fingerprint sensor, face recognition support and a 3800mAh battery with Quick Charge 2.0 technology.

The Samsung Galaxy A9 sports a 6.3-inch full-HD+ sAMOLED display with a 19:9 aspect ratio.

The handset is backed by a Qualcomm Snapdragon 660 processor, coupled with 128GB internal storage that can be further expanded.

The Galaxy A9 features digital assistant Bixby, Samsung Pay and Samsung Health.

Cyber Attackers May Use Ultrasonic Waves To Activate Siri, Google on Your Smartphone

These waves, the researchers found, can propagate through many solid surfaces to activate voice recognition systems and -- with the addition of some cheap hardware -- the person initiating the attack can also hear the phone's response

Ultrasonic waves do not make a sound, but they can still activate Siri on your cellphone and have it make calls, take images or read the contents of a text to a stranger – without the phone owner’s knowledge, suggests a new research.

Researchers have previously shown that ultrasonic waves can be used to deliver a single command through the air. However, the new research from Washington University in St. Louis expands the scope of vulnerability that ultrasonic waves pose to cellphone security.

These waves, the researchers found, can propagate through many solid surfaces to activate voice recognition systems and — with the addition of some cheap hardware — the person initiating the attack can also hear the phone’s response.

The results were presented at the Network and Distributed System Security Symposium in San Diego. “We want to raise awareness of such a threat,” said Ning Zhang, Assistant Professor of at the McKelvey School of Engineering. “I want everybody in the public to know this.”

Zhang and his co-authors were able to send “voice” commands to cellphones as they sat inconspicuously on a table, next to the owner. With the addition of a stealthily placed microphone, the researchers were able to communicate back and forth with the phone, ultimately controlling it from afar. Ultrasonic waves are sound waves in a frequency that is higher than humans can hear. Cellphone microphones, however, can and do record these higher frequencies.

“If you know how to play with the signals, you can get the phone such that when it interprets the incoming sound waves, it will think that you are saying a command,” Zhang said. To test the ability of ultrasonic waves to transmit these “commands” through solid surfaces, the research team set up a host of experiments that included a phone on a table.

Attached to the bottom of the table was a microphone and a piezoelectric transducer (PZT), which is used to convert electricity into ultrasonic waves. On the other side of the table from the phone, ostensibly hidden from the phone’s user, is a wave form generator to generate the correct signals. The team ran two tests, one to retrieve an SMS (text) passcode and another to make a fraudulent call.

The first test relied on the common virtual assistant command “read my messages” and on the use of two-factor authentication, in which a passcode is sent to a user’s phone — from a bank, for instance — to verify the user’s identity. The attacker first told the virtual assistant to turn the volume down to Level 3. At this volume, the victim did not notice their phone’s responses in an office setting with a moderate noise level.

Then, when a simulated message from a bank arrived, the attack device sent the “read my messages” command to the phone. The response was audible to the microphone under the table, but not to the victim.

In the second test, the attack device sent the message “call Sam with speakerphone,” initiating a call. Using the microphone under the table, the attacker was able to carry on a conversation with “Sam.” The team tested 17 different phone models, including popular iPhones, Galaxy and Moto models. All but two were vulnerable to ultrasonic wave attacks.

Ultrasonic waves made it through metal, glass and wood. Zhang said there is a simple way to keep a phone out of harm’s way of ultrasonic waves: the interlayer-based defence, which uses a soft, woven fabric to increase the “impedance mismatch.” In other words, put the phone on a tablecloth. (IANS)
