Embodiment
[0105] figure 2 In the anonymous authentication system for trust in the decentralized mobile crowdsourcing provided by the embodiment of the present invention, the nodes of the MCS (including mobile devices, personal computers and servers) pass through various networks (such as cellular networks, MAENT, Wi-Fi, etc.) Connected together, it mainly includes 5 types of nodes, namely MCS users, working nodes, miners, data storage nodes and cloud servers configured with SGX. Among them, the user is a node that cannot complete the data collection task, so the MCS system is used to assign the task to a group of mobile users (i.e., worker nodes) to perform the task; the worker node is a mobile user that uses its mobile device as a data collection sensor to complete the task Users; miners jointly maintain the blockchain system. For the convenience of expression, the present invention uses BC={B 0 , B 1 ,...,B k} represents the blockchain, where B i (0≤i≤k) represents the i-th bloc...
