Methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain-based storage of patrol inspection proof are provided. One of the methods includes: receiving proof information of patrol inspection at a patrol inspection site; obtaining one or more operating environment parameters of the mobile terminal at a time of the patrol inspection, wherein the one or more operating environment parameters comprise at least location information and sensor data of the mobile terminal; performing credibility verification on the patrol inspection site based on the proof information, the location information, and the sensor data using an algorithm model based on labeled identification information, labeled operating environment parameters, and historical attendance information; and in response to the credibility verification being successful, uploading verification information associated with the proof information for storing in a blockchain.

A method includes: obtaining a signal strength sequence of signals detected by a user terminal during a travel route. The detected signals are originated from signal sources disposed at different locations in the travel route, and the different location includes one or more vehicles or one or more stops. The method further includes: extracting, from the signal strength sequence, a first sequence fragment corresponding to a signal transmitted by a signal source disposed at a vehicle; determining a travel time duration of the user riding on the vehicle according to a signal strength value and time stamp information of the first sequence fragment.

This disclosure relates to network configuration using multicast address modulation. In one aspect, a method includes dividing data for completing network configuration of a device. Multiple packets are selected from the divided data. A total length of data in the multiple packets is obtained. Multicast address modulation is performed on indexes of the multiple packets to obtain a multicast target address. Data in the multiple packets is parsed based on the total length of the data in the multiple packets and the multicast target address.
