The application discloses a security authentication method and device, network equipment, a storage medium and a program product. The method comprises the following steps: receiving a first service request sent by a distributed node SCP, wherein the first service request carries a first signature and first information, and the first information comprises a first SCU identifier and first organization information; obtaining first identity information corresponding to the first information through a block chain, and verifying the first signature based on the first identity information; if the verification of the first signature fails, sending a verification failure result to the distributed node SCP; and if the verification of the first signature succeeds, forwarding the first service request to a central node NF.

The embodiment of the invention relates to a skin disease management building system based on multi-modal medical data and a method thereof. The system comprises a data collection module, a data processing module and a federal learning module. The data collection module is used for collecting multi-modal data; the data processing module is used for generating global feature data from the multi-modal data; and the federated learning module is used for performing federated learning by using the global feature data in combination with the central server so as to obtain an auxiliary diagnosis model. According to the technical scheme provided by the embodiment of the invention, through close combination of multi-modal data integration, federal learning, real-time data processing and analysis and cross-mechanism data collaboration, a privacy-protecting, efficient and intelligent skin disease management building system is formed.

The application relates to the technical field of artificial intelligence, can be applied to business system platforms such as medical health and financial technology, and discloses a data sharing method and device, computer equipment and a storage medium, wherein the privacy leakage risk of original data in an original intelligent agent is determined according to a preset dynamic privacy risk graph; the original data is risk classified according to the privacy leakage risk, the risk level of the original data is obtained, the maximum information loss threshold value that can be accepted by a target intelligent agent is reversely mapped based on the risk level, the desensitization strategy of the original data is determined according to the maximum information loss threshold value and the risk level; the original data is desensitized according to the desensitization strategy, target data is generated; the trust level of the target intelligent agent is evaluated, and it is determined whether the target data is shared to the target intelligent agent according to the trust level evaluation result and the privacy leakage risk; therefore, the application can realize efficient and safe data sharing under the premise of protecting privacy.
