on April 11，vivo held a new product launch conference，Launched the latest generation of business flagship phones vivo X Fold and vivo X Note at the launch event 。The performance of the two mobile phones launched by vivo、image、The screen and other aspects have a good flagship performance。besides， The two models launched by vivo this time have also made great efforts in terms of security and privacy，A series of targeted enhancements。
At this stage, smart phones have become an important carrier for more and more users to access the Internet，So on a smartphone device，Will store more or less personal privacy information，e.g. SMS、call information、fingerprint、human face、account number、A series of data such as passwords。 How to protect their own information security has become a major problem for business people and even all mobile phone users。
vivo's new flagship phones, vivo X Fold and vivo X Note, start from many aspects，A series of work has been done for user information security，Firmly add protection to the user's information security。
vivo X Fold and vivo X Note provide atomic privacy system at the application level、blurred geographic location、A series of functions such as camera detection to provide protection for user privacy and security。 In addition to adding a series of privacy protection functions on the application side, vivo X Fold and vivo X Note，Also uses a new generation of Snapdragon 8，Supported by the Secure Processing Unit (SPU) in the Snapdragon 8 platform，Provides wafer-level security guarding in hardware。
vivo also developed a password safe function based on the Snapdragon 8 SPU，Encrypt user passwords within the SPU using a hardware-protected key。 Password safe covers online shopping、office、Entertainment and other applications，Any usage scenarios where the password autofill function is enabled，Can be protected by SPU-level passwords。
vivo also added a new Qianjian security architecture，It relies on the powerful security technology of the Snapdragon 8 mobile platform，Build a "web" on the bottom of the software by combining the capabilities of the SPU security processing unit，Comprehensively improve security and privacy protection capabilities。 This set of thousand mirror security architecture can be used in every operation process of the device.，from wafer、kernel、Framework and application 4 levels，Comprehensive coverage of mobile phone operation security。
can be seen，The two flagship products launched by vivo this time have made great efforts to ensure the privacy and security of users.。 The realization of comprehensive privacy and security from hardware to system requires strong chip capability support，Qualcomm, which is located upstream of the supply, has already integrated security capabilities into the wafer design，In recent years, it has continuously strengthened the protection of privacy and security of its mobile platforms.。
Qualcomm added matching hardware to the mobile platform when it launched the Snapdragon 835、Haven Security Platform for Software and Biometrics。 On the Snapdragon 888 mobile platform launched at the end of 2020，It introduces the deep protection layer of Qualcomm Hypervisor，Independent operation under the bottom layer of the Android system，Create multiple isolated security environments between applications and services through Qualcomm Hypervisor，Protect and isolate data。And Qualcomm also announced，Qualcomm Hypervisor is now open to a range of partners，Will allow apps and services to communicate with more parts of the mobile platform，Provides more features in a virtualized environment。
on Snapdragon 8，Qualcomm also introduced a new Trust Management Engine (Trust Management Engine)，This new trust management engine runs at the lower level of the hypervisor，Additional Root of Trust can be provided for applications and services，Isolate and protect sensitive internal information。
We can see that，The password safe function adopted by vivo X Fold and vivo X Note is based on Qualcomm's trusted execution environment，Isolated from other data within the system，So as to achieve the purpose of data protection。 The thousand-mirror security architecture adopted by vivo X Fold and vivo X Note also makes full use of the Defense-In-Depth strategy continued on the Snapdragon 8 mobile platform，By setting different levels of security policies，Realize trust protection from wafer to cloud。
As the product chosen by many flagship mobile phones this year，Snapdragon 8 is also the world's first Android Ready SE-compliant mobile platform。The Android Ready SE standard was launched by Google in March 2021，Alliance for the development and promotion of SE safety wafer standards，The goal is to pass the open source SE security interface and program，Allow a series of smart devices to be used as house keys、car key、Use digital wallets and other security credentials，Digitize more physical items。
According to Qualcomm's official statement，Snapdragon 8 also supports the identification of fake base stations in an offline state、A series of security protection functions can be called to hide the ISP to check whether the user's screen has been spy on the screen，The overall security has reached the vault level。
As flagship models, vivo X Fold and vivo X Note have not only improved their security with the support of Snapdragon 8。 In fact, the same as many flagship phones powered by the Snapdragon 8 mobile platform，vivo X Fold and vivo X Note are also in video、performance、Display output and other aspects have been supported by the Snapdragon 8 mobile platform。
in imaging，vivo X Fold, vivo X Note and Zeiss have collaborated，And equipped with self-developed V1 image chip，It can achieve better picture effect in use、Color reproduction is more accurate and a series of improvements。
In addition to a series of technologies adopted by vivo，These two phones also benefit from the support of the powerful ISP performance on the Snapdragon 8 mobile platform。 Snapdragon 8 includes the first commercially available triple-core 18-bit ISP for mobile devices，Capable of shooting content at an incredible speed of 3.2 billion pixels per second，And also supports 8K HDR video shooting，is the first mobile platform to meet these specifications。 Higher bit can record more color information when shooting images，This is also a key for these two mobile phones to further restore the true natural color。
vivo X Flod also achieves a high degree of unity of internal and external screen quality on the folding screen for the first time，Both the internal and external screens use a 120Hz high-brush screen made of Samsung E5 material.，Brings a more comfortable look and feel unity in use。The 7-inch 120Hz high refresh rate screen used by vivo X Note also brings a visual improvement to many consumers.。also，The two flagship products launched by vivo have further adopted the under-screen ultrasonic fingerprint recognition solution provided by Qualcomm。
The internal and external screens of vivo X Fold also use Qualcomm 3D Sonic's second-generation fingerprint recognition sensor，Become the world's first folding screen phone that supports fingerprint unlocking under the internal and external screens。The vivo X Note uses Qualcomm's most advanced 3D Sonic Max fingerprint sensor。
vivo's two flagship products not only have a huge fingerprint recognition area，Fingers can be taken to more angles during unlocking，and more secure、Wet hand unlocks、One-time entry and many other advantages，Solve the pain points of the previous under-screen fingerprint unlocking solutions，With the cooperation of the Snapdragon 8 mobile platform，Greatly improved user experience。
vivo X Fold and vivo X Note powered by Snapdragon 8 mobile platform，Not just targeted shaping in terms of privacy and security，more in images such as、show、Performance and other aspects have brought about an improvement in experience。Powered by the Snapdragon 8 mobile platform，The two flagship products launched by vivo will surely bring a new experience to consumers。
It is worth noting that，In this year's flagship phone market，Except vivo X Fold and vivo X Note，There are also a series of flagship products that use the Snapdragon 8 mobile platform。
The reason is also very simple，It is precisely because the Snapdragon 8 mobile platform is in connectivity、AI、image、audio、Many aspects such as security and games have been carried out, and corresponding technical accumulation has been carried out.，And also has Snapdragon Elite Gaming、Snapdragon Sound、A series of technology matrices such as Snapdragon Connect，It can allow mobile phone manufacturers to carry out more targeted development on the basis of excellence，So as to present a better user experience for users，Perhaps this is the reason why many flagship mobile phone products use the Snapdragon 8 mobile platform.。
