WhatsApp may soon allow users to lock, unlock app via fingerprint sensor

WhatsApp is reportedly working on a fingerprint authentication feature to protect its users’ chats from being seen by others.

According to WABetaInfo, a fan site that tests new WhatsApp features early, the feature is current under development in Beta for Android 2.19.3 version.

“After working to implement Face ID and Touch ID features on iOS (that aren’t available yet for development reasons), WhatsApp has finally started to work on the Authentication feature on Android, using your Fingerprint!” said the report on Tuesday.

The fingerprint authentication feature will be available under the ‘Privacy’ menu. Once you enable the fingerprint feature, your WhatsApp will be completely protected from others to be seen.

“The user will need to authenticate his identity in order to open WhatsApp (from the app icon, from the notification or from external pickers). It will protect the entire app, so it’s not used to lock specific conversations,” the report added.

This feature would be available in future for any Android user (and later for iOS users too) having Android Marshmallow and newer operating systems and a fingerprint sensor.

Google Wins US Approval for Radar-Based Hand Motion Sensor

Google Wins US Approval for Radar-Based Hand Motion Sensor

Alphabet’s Google unit won approval from US regulators to deploy a radar-based motion sensing device known as Project Soli.

The Federal Communications Commission (FCC) said in an order late on Monday that it would grant Google a waiver to operate the Soli sensors at higher power levels than currently allowed. The FCC said the sensors can also be operated aboard aircraft.

The FCC said the decision “will serve the public interest by providing for innovative device control features using touchless hand gesture technology.”

A Google spokeswoman did not immediately comment on Tuesday, citing the New Year’s Day holiday.

The FCC said the Soli sensor captures motion in a three-dimensional space using a radar beam to enable touchless control of functions or features that can benefit users with mobility or speech impairments.

Google says the sensor can allow users to press an invisible button between the thumb and index fingers or a virtual dial that turns by rubbing a thumb against the index finger.

The company says that “even though these controls are virtual, the interactions feel physical and responsive” as feedback is generated by the haptic sensation of fingers touching.

Google says the virtual tools can approximate the precision of natural human hand motion and the sensor can be embedded in wearables, phones, computers and vehicles.

In March, Google asked the FCC to allow its short-range interactive motion-sensing Soli radar to operate in the 57- to 64-GHz frequency band at power levels consistent with European Telecommunications Standards Institute standards.

Facebook raised concerns with the FCC that the Soli sensors operating in the spectrum band at higher power levels might have issues coexisting with other technologies.

After discussions, Google and Facebook jointly told the FCC in September that they agreed the sensors could operate at higher than currently allowed power levels without interference but at lower levels than previously proposed by Google.

Facebook told the FCC in September that it expected a “variety of use cases to develop with respect to new radar devices, including Soli.”

The Soli devices can be operated aboard aircraft but must still comply with Federal Aviation Administration rules governing portable electronic devices.
