The invention discloses a cloud data security sharing method based on a block chain. The method comprises the steps that 1, a trusted certificate authorization center provides a unique global identityID and a digital certificate according to identity information submitted by a user or an attribute authorization center; the attribute authorization center assigns attribute public and private key pairs for each attribute and distributes attributes for legal users; 2, encrypting and uploading the user data; 3, downloading data by the user; and 4, data decryption: the attribute key set of the usermeets the access strategy of the data, and a decryption key can be obtained through an attribute-based decryption algorithm, so that the data to be accessed can be decrypted. The method has the advantages that the data sharing safety and the data sharing efficiency are improved in an untrusted environment, and the compliance of entity behaviors is supervised.

An embodiment of the invention provides a unified user identification generation method, device and system. The method comprises the following steps: unified application identifications distributed inadvance for applications can be searched based on application identifications via a service platform, and unified user identifications for users can be generated according to the unified applicationidentifications and user identifications. If two applications are the same in unified application identification and the user identifications are the same in corresponding associated information, thesame unified user identification is distributed for the users via the service platform; if the two applications are different in unified application identification, different unified user identifications are distributed for the users via the service platform even if the user identifications are the same in corresponding associated information, the unified user identifications are generated in sucha way, and the same users in different applications can be identified via a terminal device according to the unified user identifications; data sharing, data isolation and smooth data migration amongapplications can be realized in a flexible manner.

The invention provides a positioning sensor data sharing method and system based on a vehicle-mounted terminal, and the vehicle-mounted terminal. The positioning sensor data sharing method comprises the following steps: acquiring first positioning sensor data collected by an intelligent terminal located at the same vehicle with the vehicle-mounted terminal; acquiring second positioning sensor datacollected by a vehicle-mounted positioning module; and positioning the vehicle based on the first positioning sensor data and the second positioning sensor data. Through the positioning sensor data sharing method and system based on the vehicle-mounted terminal, and the vehicle-mounted terminal provided by the invention, the well vehicle positioning is realized by sharing the positioning sensor data respectively collected by the shared vehicle-mounted terminal and the intelligent terminal, thereby greatly improving the positioning precision.

The present invention provides a management system for utilizing code identify management insurance inoculation product. The system includes a system computer, a terminal, a printer, an input device, a product code information database, a code generator, a product code table database, a product code scutcheon, a product warehouse management system, a product financial management system, a product object picture database, a manufacturer information database, a management of vaccinate site, a safety monitoring system of vaccinate. Since using the product code scutcheon provided by the invention as identification card preventing the inoculation goods access the management system, the register product code replaces the previous sorts, factory, preparation formulation, norm, technics etc of the register goods, the working efficiency is enchanced 4 times and reducing the error, and achieving the data share of each business module of the vaccinate administration section, having important meanings to improve medical management level and the disease prevention control Strategy research.

The invention provides a navigation data sharing method, a vehicle-mounted device, a mobile terminal and a mobile terminal navigation system. The method provided by the invention comprises the following steps: collecting vehicle-mounted global satellite navigation system data obtained from a vehicle-mounted global satellite navigation system receiver; and sending the vehicle-mounted global satellite navigation system data to a mobile terminal. In addition, the invention provides a method executed by a mobile terminal, comprising the following steps: receiving vehicle-mounted global satellite navigation system data from a vehicle-mounted device; and carrying out navigation on a mobile terminal according to the vehicle-mounted global satellite navigation system data. The navigation performance of the mobile terminal during vehicle running can be improved, and traffic accidents caused by navigation error can be reduced.
