Privacy Protection 2.0

Privacy Protection 2.0

Privacy Protection is designed to protect the privacy and data of human face and body. It is based on deep learning algorithm and complies with GDPR.

Privacy Protection 1.0 version realizes real-time occlusion of human body and face and allows users to access recoverable video without the mosaic mask. With the fundamentals of the first version, the Privacy Protection 2.0 offers additional occlusion options (irregular polygons, mosaics, and colored blocks) and allows code exporting based on specified targets, ensuring the privacy safety of people and places.


Benefits

Non-pixelated human targets

Specified human targets from external sources or from local databases can be selected to be non-pixelated, providing privacy and security protection in evidence collection.

Irregular polygons and mosaic occlusion

Supports irregular polygons, mosaic and colored blocks occlusion methods (by camera),

Real-time privacy occlusion

Supports real-time mosaic of human face and body to protect personal privacy. In addition, it also allows face and human attributes analysis.

Video Recovery

The privacy protection system allows users to access recoverable video without the mosaic mask. It can be used as legal evidence in case of an event.

Typical Scenarios

Courtroom

Courtroom

Through the privacy protection system, the witnesses who testify in the witness room are automatically masked with real-time mosaic to protect their privacy and security. It encourages witnesses to testify in court and saves administrator’s time from the heavy manual work of privacy masking.
Nursing room

Nursing room

In nursing homes, sensitive areas such as bedrooms are not suitable for direct monitoring. With the privacy protection solution, sensitive areas can be coded by camera, which not only protects the safety of the elderly, but also reduces the labor cost of medical staff.
