【Abstract】With the rapid development of computers and networks, more and more convenient services are provided relying on the Internet. In this paper, we focus on the data sharing in students' physical health tests. To reduce the burden of filling in information manually, physical health test service providers have designed a mode of obtaining students' information, including personal information and test results, from a trusted third-party tester for gathering all physical health items and automatically filling. This mode is called one network unified management. However, if the trusted third-party organization sends too much unnecessary information to service requester, dishonest requester will maliciously use the students' redundant information, which causes great security risk to students' information. To solve the problem, this paper designs a token distribution scheme adapted to that mode based on programmable blockchains. Secure and fast data sharing is approached. Both traceability and evidence collection are available. For a network with 500 participants and size of maximum token set is 5 x 210, data sharing can be completed within 13.04 microseconds while traceability can be completed within 3.61 microseconds of extra time consumption. Ensuring safety and traceability, the time consumption of the scheme is proved to be linear with the increasing population of participants. It is also tested with real physical health test data, proving that the scheme is available in reality.
