Car Interior Privacy Exposure Warning: How Non-Optical MEMS Sensors Safeguard Passenger Safety and Privacy （Part 3）

Data Security Reinforcement: Multi-Layer Protection for Sensor Data

Beyond the privacy benefits of the sensors themselves, data security measures must also be reinforced.

Encrypted transmission technologies (such as SSL/TLS) can ensure the safety of data during transfer. Strict access control mechanisms should be implemented so only authorized personnel can view or handle sensor data.

Data anonymization is another effective method. For example, Audi AG has developed a process that anonymizes vehicle sensor data before transmitting it to external systems. This technique calculates anonymization probabilities and substitutes measurement time and location data with anonymized equivalents — further protecting user privacy.

Future Trends: Balancing Safety and Privacy in Smart Cabins

With the continuous advancement of AI and smart cockpit technologies, the intelligent cabin has become a key innovation frontier in the automotive industry.

Starting from 2025, C-NCAP (China’s New Car Assessment Program) will include “Child Presence Reminder Function” in its evaluation criteria, rewarding vehicles equipped with CPD systems.

By that time, it is estimated that over ten million CPD-enabled vehicles will be on the road.

Balancing functional performance and privacy protection will be essential.

As a leading player in sensor technology, ADW continues to invest in R&D to overcome technological bottlenecks and empower the development of smart vehicles.

According to the Gaogong Intelligent Vehicle Research Institute, between January and April 2023, 251,200 passenger cars in China were delivered with standard Occupant Monitoring Systems (OMS), and nearly 10,000 were equipped with in-cabin biometric detection.

By 2025, these numbers are expected to exceed ten million units.

Technological choices are no longer just about functionality — they directly affect the privacy and safety of millions of car owners.

MEMS ultrasonic sensor solutions represent not just an engineering advancement, but also a commitment to social responsibility and user privacy protection.
