Intercom-Enabled Smart Locks: Unveiling the Hidden Dangers and Safeguarding Your Home Security

In recent years, smart locks have gained widespread popularity due to their convenience, becoming the preferred choice for many households. However, beneath the seemingly secure exterior of smart locks lies a vulnerability that allows them to be opened using walkie-talkies, a seemingly unbelievable feat with a profound scientific basis. This article will unveil the principles behind intercom-enabled smart lock opening, explore the security risks associated with this phenomenon, and discuss how to ensure home safety.

I. Principles and Classification of Smart Locks

Smart locks, as the name suggests, are intelligent devices that utilize electronic technology to achieve door lock functionality. Their core principle lies in transforming traditional mechanical lock unlocking methods, such as keys and passwords, into more convenient and efficient electronic operations. Based on different unlocking methods, smart locks can be primarily categorized as follows:

1. Fingerprint Locks: These locks unlock by recognizing fingerprint information, offering relatively high security. However, ensuring accurate fingerprint collection is crucial, and if fingerprint information is compromised, the security risks are substantial.

2. Password Locks: These locks unlock by entering a password, providing a simple operation. However, they face a high risk of password disclosure, necessitating regular password changes.

3. Card Swipe Locks: These locks unlock by swiping a card, offering a straightforward operation. However, cards can be easily lost, and there exists a risk of card duplication.

4. Facial Recognition Locks: These locks unlock by recognizing facial features, offering high security. However, they are susceptible to environmental lighting influences and may be prone to photo or video deception.

5. App-Unlock Locks: These locks unlock through mobile phone app control, providing flexible use. However, they pose security risks if the phone is lost or stolen.

6. Fingerprint + Password Locks: Combining fingerprint recognition and password input, these locks offer enhanced security but involve relatively cumbersome operation steps.

7. Fingerprint + Card Swipe Locks: Combining fingerprint recognition and card swipe unlocking, these locks enhance security but require carrying a card.

8. Fingerprint + Facial Recognition Locks: Combining fingerprint recognition and facial recognition, these locks offer the highest security but come at a higher device cost.

Beyond unlocking methods, smart locks also possess various functionalities, including:

• Remote Control: You can control the door lock through a mobile phone app, enabling convenient remote unlocking or checking lock status.

• Alarm Function: When the lock is pried open, vandalized, or unlocked illegally, it will sound an alarm, alerting the user.

• Recording Function: It records information such as lock opening time, unlocking method, etc., allowing users to conveniently check the lock usage history.

II. How Intercoms Open Smart Locks?

Intercoms, as two-way mobile communication tools, are commonly found in various work environments. It might be hard to imagine that they can actually open smart locks. However, this seemingly absurd phenomenon has a scientific basis.

1. High-Frequency Pulse Signals: Intercoms operate by converting voice information into high-frequency pulse signals, which are transmitted through an antenna. Another intercom receives these signals and converts them back into audio information, enabling two-way communication. However, for the circuit board of a smart lock, these high-frequency pulse signals can have a significant negative impact.

2. Lack of Internal Voltage Regulator Module in Smart Locks: To reduce costs, some lower-end smart locks may omit the internal voltage regulator module, making them unable to withstand voltage fluctuations caused by high-frequency pulse signals. This can lead to system chaos, even misinterpreting unlocking commands, ultimately resulting in the lock opening.

3. Interaction Between Intercom Antenna and Smart Lock: When the intercom antenna is close to the smart lock's keyboard or fingerprint module, the high-frequency pulse signals interfere with the lock's internal circuitry, leading to misinterpretations of unlocking commands and ultimately opening the lock.

III. Risks and Dangers of Intercom-Enabled Lock Opening

Using an intercom to open a smart lock is both a technical vulnerability and a significant security risk.

1. Property Security Risks: Intercom-enabled lock opening signifies a compromised lock security, exposing household property to substantial security risks.

2. Personal Privacy Disclosure: During intercom-enabled lock opening, personal information stored in the lock, such as fingerprint information, password information, etc., may be compromised, leading to privacy security issues.

3. Public Security Risks: If intercom-enabled lock opening technology falls into the hands of criminals, it could become a tool for theft, burglary, and other criminal activities, posing a serious threat to public security.

IV. How to Avoid Intercom-Enabled Lock Opening?

To avoid the risk of intercom-enabled lock opening, we should take the following measures:

1. Choose Reputable Brands and Avoid Low-End Products: When purchasing a smart lock, select a brand with a good reputation and avoid buying low-end products in pursuit of cheaper options.

2. Carefully Read the Product Manual: After purchasing a smart lock, carefully read the product manual to understand its functions, usage methods, and anti-theft measures.

3. Regularly Change Passwords: Regularly change the smart lock's password to prevent it from being cracked by others.

4. Pay Attention to Installation Location: When installing a smart lock, try to avoid placing it in areas that are easily accessible to others.

5. Enhance Security Awareness: Regularly enhance your security awareness. When going out, make sure to lock doors and windows. Do not easily trust strangers and be vigilant against criminals attempting to use intercom-enabled lock opening for theft.

V. Future Prospects for Smart Lock Security

Although intercom-enabled lock opening has exposed vulnerabilities in smart lock security, security technology for smart locks is continuously improving with technological advancements.

1. Chip Encryption Technology: Implementing more advanced chip encryption technology enhances the lock's resistance to attacks, preventing them from being cracked by devices like intercoms.

2. Multi-Factor Authentication Mechanisms: Introducing multi-factor authentication mechanisms, such as fingerprint + password, facial recognition + password, etc., enhances unlocking security.

3. Intelligent Recognition Technology: Applying artificial intelligence technology to recognize user behavior can prevent illegal unlocking, improving the lock's security performance.

VI. Conclusion

The development of smart locks has brought numerous conveniences to our lives. However, we must also recognize their existing security risks and take appropriate preventative measures. Choosing reputable brands, enhancing security awareness, and maintaining vigilance are crucial for safeguarding home security and enjoying the benefits of intelligent technology.

In the future, smart lock security technology will continue to evolve. We anticipate the emergence of even more secure and convenient smart lock products, bringing further convenience to our lives.
