With the popularization of artificial intelligence and Internet of Things technology, smart home such as smart door locks, sweeping robots, and intelligent whole-house temperature control have gradually become popular, which have been integrated into all aspects of work and life in modern society, and have significantly improved people's quality of life. It is worth noting that if the sensitive data of smart home products is used by people with ulterior motives, it may cause information leakage and pose a threat to national security.

- "The Silent Listener". If a smart speaker device is maliciously implanted with a Trojan horse program by a person or organization with ulterior motives, it may bypass the use authorization and regulatory requirements, record the user's voice without being awakened, and upload the illegally collected user data to the cloud storage. Criminals may continue to record the user's daily conversation content through remote control, violating personal privacy and turning the smart speaker at home into a "silent monitor". Once this kind of smart speaker equipment is placed in a sensitive place involving secrets and is controlled and controlled by foreign espionage and intelligence agencies, it is very likely to invisibly leak state secrets.

- "The Snooper in the Shadows". If the smart camera does not have technical precautions in cloud video encryption, user authentication, password setting, etc., it may be possible for criminals to obtain control of the camera through technical means, which will lead to the leakage of user information or video content, and even unknowingly carry out real-time monitoring. If the video capture equipment installed in a sensitive place involves security vulnerabilities and is connected to the Internet, it will cause the risk of leakage.

- "The Invisible Inluder". Smart door locks can be switched through passwords, biometrics or mobile phone APP, and people no longer need to carry their keys with them, which provides great convenience for work and life. However, due to the design flaws of some low-quality smart door locks, attackers can crack and open them in seconds with simple tools. If such smart door lock devices are used to protect confidential places, once criminals crack them through cyber attacks or physical means, they can "travel unimpeded" in sensitive areas, posing a threat to national security.

Reminder from the state security organs

In the era of the Internet of Everything, while enjoying the convenience brought by smart homes to work and life, we should also raise awareness of prevention, establish a firm concept of confidentiality, and not give foreign espionage and intelligence agencies the opportunity to endanger China's national security through the loopholes of smart home equipment.

- Pay attention to the selection of compliant equipment. When buying smart home equipment, pay attention to choosing regular brands, through legitimate channels, and give priority to products that have passed national safety certification (such as CCC mark) or meet international safety standards.

- Properly set privacy permissions. When using smart home devices, you should set a strong password with high confidentiality for the smart home, turn off the permission and remote control function for collecting and sharing personal information that is not necessary, and install official patches to patch device vulnerabilities in a timely manner.

——Understand and master security knowledge. When using smart home devices, it is necessary to consciously improve learning awareness and risk awareness, continue to pay attention to the latest digital security risks and defense strategies, actively learn how to identify common digital security threat scenarios such as data information leakage and malicious phishing attacks, and actively popularize the knowledge of how to use smart home devices safely to family members and friends, and avoid related risks as much as possible.

Home intelligence is the trend of science and technology to change life, and it is the way to facilitate human life. To live a good life, you should also live a good life that is safe. When everyone enjoys the convenience brought by smart home products, they should also improve the safety awareness of the use of smart home products, especially to avoid the application of smart devices that do not meet the confidentiality requirements to confidential sensitive places, and jointly build a people's defense line to safeguard national security.
