[Huawei Developers] Martin Bieber:
In an era of the Internet of Things, our lives have been made more convenient by continuously optimized apps across distributed scenarios in contexts such as the smart home, smart office, and smart travel. Redefined product forms and enhanced cross-device collaboration have also contributed significantly to getting rid of limitations in terms of device connection. In light of this, highly reliable and accurate trusted connections between smart devices become crucial not only for improving the smart life experience, but also for protecting consumers' privacy and security of consumers' property.

Born for a converged intelligent life experience

The key factors for optimizing the smart life experience are improving the utilization rate of smart devices, removing the restrictions on device usage scenarios, and leveraging multiple types of devices. Born to address these issues, HiChain 1.0 for distributed and trusted device connections builds a software system across multiple devices to comprehensively enable trusted connections of devices using distributed technology, facilitating secure, convenient, and efficient device interconnections.

12 core functions enabling trusted connections in distributed scenarios

HiChain 1.0 securely connects core devices (such as mobile phones, tablets, and PCs), hub devices (such as tablets, TVs, and speakers), and accessories (such as watches and headsets), and performs binding, authorization, and transmission/control operations. In addition, HiChain 1.0 improves the establishment and transmission of the trust relationship, as well as data transmission and control based on the trust relationship. With the 12 core functions of HiChain 1.0 in distributed scenarios, trusted connections between the same account, across accounts, and independent of accounts become a reality, and various intelligent devices can collaborate with each other to assist people in daily life and work situations.

Remove cross-device limitations and build an interconnected life

In today's modern world where smart device forms including smart speakers, watches, TVs, and even vehicles have sprung up, consumers' demands on cross-device and multi-screen collaboration have also been soaring. HiChain 1.0 utilizes its proprietary technologies to unblock connection channels to allow different smart devices to interconnect with each other, as well as integrate device advantages for an optimized cross-device collaboration experience, forming a "1+1 > 2" synergy effect across a wide range of scenarios such as travel, mobile office, and social communication.

Intelligent travel: making journey smarter

The mission of vehicles has evolved from "making travel easier" to "making travel smarter". Closely related to this development is HiChain 1.0's enabling of secure binding between mobile phones and vehicles, end-to-end two-way authentication, and encrypted transmission to prevent attacks. This means that user privacy will not be disclosed even if data is intercepted. In this way, a seamless HiCar service scenario is implemented whereby users can project their phone screen to the vehicle screen, and seamlessly control phone apps (such as navigation, music, phone, and SMS apps) projected to the vehicle screen.

Smart office: making work more efficient

Good tools are crucial to a job being done properly. As such, HiChain 1.0 leverages its technical advantages to deliver an optimally secure screen projection and control experience by allowing mobile phones to obtain the unique identifier of a PC through scanning the QR code or using NFC to tap against the PC, and then project the screen to the PC desktop. This is especially handy for working at home efficiently and working together with colleagues.

One-tap TV projection: making connections more flexible

HiChain 1.0 also utilizes protocols such as Miracast to establish a connection between the phone and the TV (using the Miracast security mechanism), obtain the TV's unique identifier through the Miracast channel, and project video and audio from the phone to the TV and speaker. It can also return the video data collected by the TV's camera to the phone, facilitating a seamless and immersive entertainment experience between phones and TVs.

HiChain 1.0 will continue to give full play to its technical characteristics to enable trusted connections between devices using distributed technologies. Various types of smart devices will be able to collaborate with each other in a secure and trusted manner to overcome restrictions across different usage scenarios, and provide assurance for consumers to achieve a seamless and intelligent life experience with multi-screen collaboration.
