What about privacy? Android M will bring mobile phones into the era of "full-time monitoring"

The next generation Android operating system "Android M" launched by Google will be able to enable the anytime perception function for a series of sensor devices on smartphones, making the input of "metadata" such as Wi-Fi, microphone, light sensitivity, camera, etc. the data source of the coprocessor Sensor Hub, helping the phone to determine the user's state and environment, and thus adjust the functions of the system and application software to adapt.

This means that any smartphone or tablet device with a coprocessor will be able to monitor or even "surveil" the surrounding environment after installing Android M. According to sources, Google will support STMicroelectronics as a supplier of coprocessors. The chip manufacturer headquartered in Geneva, Switzerland, has begun to "Amway" its products to major smartphones around the world.

Currently, the two most famous smartphone manufacturers in terms of coprocessors are Apple (M series coprocessors) and Motorola (X series mobile computing systems).

For example, Apple's M7 and M8 coprocessors can keep a record of user movements at all times through motion sensors such as gyroscopes while using negligible power.

Motorola's coprocessor system is relatively more complex, including a natural language processor and a contextual computing processor, which can listen to the user's voice command "OK Moto" at any time, and call on infrared and photosensitive elements. Users can light up the screen and view notification content by waving their hands above the screen.

Android M's coprocessor, Sensor Hub, manages all sensors on the phone with lower power and captures more metadata for calculations.

This new feature of Android M will bring more data that can be obtained, calculated and called to smartphones, which will inevitably bring some new interactive experiences to users, as well as more "intelligent" functions in the future. But at the same time, considering that the Android operating system has always been developed by Google, Google's advertising system will be able to obtain a new source of data this time, so as to push more accurate advertisements and increase advertising revenue. All along, mining the value of data and bringing benefits to the advertising system have been the main intentions of Google's research on some black technologies. It is estimated that this time, people who advocate privacy protection will be restless again.
