The safest mobile phone encryption Titan M

        Google's latest Pixel 3 mobile phone has been released. The photos that have been processed by the Visual Core chip are impressive, and can be compared with multi-camera imaging. Google has once again changed the status quo of mobile phone camera hardware. This depends on the powerful algorithm behind Google. , hardware team. This time, Ptinel 3 added a new security chip Titan M, which is mainly responsible for protecting the internal data, system and personal biometric information of Pixel 3. Yesterday Google explained the main role of the Titan M chip in the blog, to see how Google is building the most secure mobile phone.
