Recently, public information from the State Intellectual Property Office shows that the invention patent applied for by DeNike for “a privacy protection model update method for smart home central control screens based on federated learning” has officially entered the publication stage.
The patent application was submitted in March 2026. A privacy protection model update system is built through the collaboration of cloud servers and central control screen terminals. The terminal side is equipped with local lightweight training and privacy parameter upload modules, and the cloud side is responsible for global model aggregation, updating and synchronization, achieving collaborative optimization of global general models and user personalized models.
This technology has completely solved the three major industry problems of smart home central control screens that relied entirely on cloud model computing in the past: First, all user data can complete local training without uploading to the cloud, fundamentally avoiding the risk of privacy leakage in users’ home life, and fully complying with the supervision of user data privacy protection in various regions around the world.
Second, local training can generate exclusive personalized models that fit the usage habits of different families, greatly improving the adaptability of use. Third, only model parameters need to be transmitted instead of full data, which reduces communication resource consumption by more than 60%. It is more adaptable to overseas areas with imperfect network infrastructure and can effectively reduce user costs.
As a veteran company that has been deeply involved in the fields of smart communities and smart homes for more than ten years, Dinak entered the capital market in 2020 and is headquartered in Xiamen, Fujian. It has the advantages of the entire industry chain of R&D, production, and sales of product lines such as building intercoms, smart homes, smart medical care, and smart hotels. It is one of the core suppliers in the domestic security intelligent field.
In 2025, the company’s annual revenue will reach 660 million yuan, of which building intercom products account for 50.74%, smart home products account for 21.03%, and smart ward and outpatient-related products account for 16.32%. A multi-category collaborative development pattern has taken shape.
Compared with leading companies in the industry, Dinex has outstanding advantages in customized technology for segmented scenarios and cost-effective products. It is especially suitable for the implementation needs of small and medium-sized overseas smart communities, residential projects, and smart hotels. It can provide integrated customized solutions from hardware to software.
In addition to the central control screen privacy protection patent disclosed this time, DINIKE has disclosed more than 50 invention patents and appearance patents in the past year. The technology layout covers smart home multi-device linkage, home security warning, energy consumption management,
In the fields of building intercom audio and video optimization, smart hotel non-sensory check-in, and cognitive impairment health intervention, 12 appearance patents have been authorized, and more than 30 invention patents have entered the substantive review stage. The thickness of the technical reserve continues to increase, and it can provide global customers with stable technology iteration support and product update services.
For global buyers, the entire range of Dinek products are equipped with self-developed core technologies. They have outstanding advantages in privacy protection, scene adaptation, and cost control. They can adapt to the regulatory requirements and usage habits of different countries and regions. They are a high-quality choice for procurement of projects such as smart communities, smart homes, and smart hotels.
