Building on the inaugural DataX Conference, this event aims to bring together visionaries and thought leaders interested in the circulation of data elements, the formation of data element markets, and a data-driven future. From technology to products and applications, and from policy to business and science, participants will convene for in-depth discussions on all matters surrounding data. The 2022 Second DataX Conference focuses on healthcare, collaborating with key industry leaders and cutting-edge enterprises to explore ways to promote safer, more precise, and more effective development within the healthcare sector.
In his opening remarks, Dr. Chen Xun, Chairman of Yifang Health Data, stated that human scientific and technological progress is rapidly entering the Fourth Paradigm—an innovation paradigm centered on data, following the three preceding paradigms of empirical observation, theoretical science, and computational simulation. As a practical science, medicine is increasingly transforming its practices into data. As highlighted at the previous conference, “data is knowledge,” and data derived from medical practice constitutes a treasure trove of knowledge for the advancement of medicine. Since its inception, Yifang Health Data has remained true to its original mission, steadfastly promoting and exploring the circulation and application of healthcare data. On the technical front, the company has open-sourced privacy-preserving secure computation technologies to share emerging innovations with industry practitioners. In terms of product development, its solutions have gained adoption and usage across multiple fields and industries, with its healthcare products gaining momentum and gradually maturing. Conceptually, the content and implications of privacy-preserving computation have become increasingly enriched and profound amid the wave of industrial development. Concluding his address, Dr. Chen expressed his expectation to work together with all stakeholders to co-create a “data-driven, digital, and intelligent” future for healthcare.

In his keynote address titled “Building the ‘Internet of Data and Computing’ in Healthcare,” Dr. Luo Zhen, CEO of Yifang Health Data, shared the company’s insights and perspectives on fostering an ecosystem for healthcare data circulation and developing an Internet of Data and Computing. He highlighted the “heterogeneity” challenges encountered in this endeavor, such as trust heterogeneity—which can be addressed through privacy-preserving computation technologies—referring to the mutual distrust between data providers and data consumers; the adoption of differing data standards and organizational frameworks across various data sources; the use of diverse storage and computing methods for raw data; and the utilization of heterogeneous computational resources by data sources or computing nodes.
To address these challenges, Yifang Jianshu has developed a series of independently researched and advanced technologies and products, exploring and resolving the technical dilemmas encountered in building the Data and Computing Internet.
Especially in the healthcare industry, Yifang Jianshu has developed general-purpose and multi-scenario medical product tools, such as data governance tools, knowledge graphs, and artificial intelligence models widely applied across various healthcare scenarios. By leveraging technology and tools to govern data from different nodes in a unified manner, data consumers can process data as if it were all aggregated in a single location, even in the presence of various “heterogeneous” data issues. Furthermore, Yifang Jianshu is building an open ecosystem for data applications, enabling professionals with insights, expertise, and needs related to data to participate in this open data ecosystem. Through diverse data, models, and computing capabilities, this approach creates infinite value for various industries and applications.

The “Overall Plan for the Comprehensive Reform Pilot of Market-Based Allocation of Production Factors,” issued by the State Council at the beginning of this year, mentions opening up certain high-value public data, including health and medical data, to the public to promote circulation and value creation. Meanwhile, relevant authorities have repeatedly emphasized the data trading paradigm of “raw data remaining within its domain, with data being usable but not visible.”
“Raw Data Does Not Leave the Domain” refers to a standard followed in data exchange and sharing. In the joint creation of data value among data requesters, data providers, multiple data sources, and between these sources and the requesters, raw data is not exchanged. Instead, through an “available but invisible” approach, multiple data sources collaboratively express data value via computation. This requirement effectively means that the future data ecosystem cannot evolve into an unrestricted aggregation of data. Rather, each data source should uphold its responsibilities for data security and privacy protection. By building a distributed data network, data requesters can leverage this infrastructure to generate value through computation.

Signing Ceremony at the Conference Venue
At the conference, China Academy of Information and Communications Technology (CAICT), Fudan University’s Institute of Intelligent Medicine, XtalPi, and Wingsoft Health Data held a strategic cooperation signing ceremony. In addition, the “White Paper on Privacy-Preserving Computation Applications in Healthcare (2022),” jointly compiled by the Internet Medical Health Industry Alliance, the Privacy-Preserving Computation Alliance, Wingjian (Shanghai) Information Technology Co., Ltd., together with medical institutions, technology service enterprises, and other relevant organizations, was officially released at the event. Min Dong, Deputy Director of the Cloud Computing and Big Data Research Institute under CAICT, provided an interpretation of the white paper. The document offers an in-depth analysis of the healthcare privacy-preserving computation industry from perspectives including current development status, application domains, opportunities and challenges, and future planning, while also highlighting a number of outstanding application cases. Wingsoft Health Data’s participation underscores its commitment to collaborating with industry peers to drive the rapid advancement of medical and healthcare services.
