BEIJING, July 26, 2024 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, today announced that it utilized homomorphic encryption and federated learning building an advanced data structure architecture. The architecture integrates federated learning and partial homomorphic encryption, and this integration protects data privacy while enabling efficient data analysis and sharing.

Homomorphic encryption is a special encryption technique that enables computational operations to be performed in an encrypted state without decrypting the data. By utilizing homomorphic encryption, it is possible to compute and share data in an encrypted state while protecting data privacy and integrity, which is useful for some scenarios involving sensitive data. Federated learning is a distributed machine learning technique that enables model improvement by allowing multiple participants to train models on their respective local datasets without sharing the original data, and aggregating the learned parameters of these models into a global model. In data structuring, federated learning can address the issues of data privacy and data security.

WiMi’s data structure architecture based on homomorphic encryption and federated learning enables data collaboration, sharing and integration without revealing the original data content. Participants can train models and update parameters without direct access to the original data of other participants, providing an effective and reliable data fusion solution for secure sharing and analysis of big data. The architecture not only protects the privacy of data, but also improves the efficiency and accuracy of data integration. In practical application, firstly, the requirements of the data architecture need to be analyzed in detail, including data type, data size, and computational tasks. Based on the results of the demand analysis, the design objectives and functions of the data structure are determined. Then, homomorphic encryption technology is utilized to encrypt the user’s sensitive data to ensure that the data remains encrypted during the computation process. The encrypted data from the participating parties are then aggregated and computed using federated learning techniques. The federated learning process can be implemented using secure multi-party computation protocols or differential privacy techniques to ensure data privacy and accuracy of computation results.

The fusion application of homomorphic encryption and federated learning is of great significance in the data structure, which can provide efficient computation and analysis capabilities while protecting user privacy, bringing more possibilities for technology utilization in the technology industry. This application is expected to play an important role in medical and financial fields, promoting secure data sharing and innovative research, and promoting the continuous development of the big data field.

For example, in the medical field, patients’ medical data often involves personal privacy, and how to share and analyze medical data while ensuring data privacy has been a challenge for medical informatization. WiMi’s architecture provides a feasible solution for secure sharing of medical data by combining federated learning and homomorphic encryption. Hospitals and research institutes can work together to train and optimize medical models without disclosing patients’ personal information, improving the quality and efficiency of medical services. In the financial sector, financial institutions are faced with a large amount of sensitive data, such as customer identity information and transaction records. The leakage of these data may have a serious impact on the reputation of financial institutions. The data structure architecture based on homomorphic encryption and federated learning researched by WiMi can help financial institutions improve the accuracy and efficiency of their risk control models and effectively prevent financial risks by encrypting data sharing and analyzing them under the premise of ensuring data security. In addition, with the popularization of IoT devices and the development of social networks, data generation and sharing have become more and more frequent. How to realize the effective integration and utilization of data while protecting personal privacy has become an urgent problem in these fields. The data structure architecture based on homomorphic encryption and federated learning provides an effective solution to these problems.

In the future, WiMi will continue to conduct in-depth research and development of data structure architecture based on homomorphic encryption and federated learning and promote the application and popularization of such architecture in various fields. In the future, this architecture combining federated learning and homomorphic encryption will become an important development direction in the field of big data.

The Sleep System That Understands You Best.

BERLIN, Sept. 6, 2026 /PRNewswire/ — DUVA, created by Fitnexa, is introducing DUVA ONE at IFA Berlin 2026. This intelligent in-ear sleep system is designed to sense changes in the user and the bedroom, then personalize audio, noise control, and device behavior throughout the night.

Most sleep wearables explain what happened after users wake up. DUVA ONE is designed to help while the night is still happening. Its low-profile earbuds, environment-sensing charging case, and app work together to determine when and how to respond.

A user might start the night with a podcast over Bluetooth. After they fall asleep, DUVA ONE can introduce locally stored sleep audio and optimize power use. If a partner begins snoring or traffic grows louder, it can adjust ANC or add sound masking. In the morning, a private offline alarm wakes only the wearer, without requiring an active phone connection.

In-ear PPG and motion sensors estimate sleep stages and track heart rate, HRV, sleep position, and movement, while the case monitors noise, light, temperature, and humidity. The AI Agent interprets these signals alongside playback status and personal preferences to select an appropriate response. Users control sleep audio, playback duration, ANC strategy, and nighttime interventions in the DUVA App.

“Sleep does not happen in a static environment, so sleep technology should not remain static either,” said Diego, Founder of Fitnexa. “DUVA ONE is designed to respond while sleep is still happening.”

Key Highlights

Layered noise relief: Passive isolation, Hybrid ANC, and sleep audio provide noise reduction of up to 42 dB, with Transparency Mode and adaptive ANC calibration.Personalized AI sleep guidance: The AI analyzes the user’s real-time sleep state and generates personalized audio guidance to help them gradually fall asleep.Side-sleeping comfort: Each fitted earbud weighs approximately 3.3 grams and has an approximately 9.9 mm low-profile design. Two ear-tip shapes and multiple tip and stabilizing-wing sizes provide more than 40 fit configurations.All-night battery: Up to 16 hours in the most power-efficient configuration, including 13 hours of local audio with ANC off and 9.5 hours with ANC on. The USB-C and wireless charging case provides up to five additional recharges.Private offline alarm: Alarms gradually increase in volume and offer 5, 10, or 15-minute snooze options through the earbud controls.Privacy-first sensing: DUVA ONE does not record conversations, store ambient audio, or upload raw environmental audio. Users can disable individual sensors and delete historical data.

DUVA ONE is planned for release in October 2026 at a target retail price of US$349.99, with target markets including the United States, Canada, the United Kingdom, the European Union, and Australia.
