Privacy data reporting method and apparatus, and storage medium

A terminal device, comprising:

• a memory, configured to store a computer program;
• a processor, configured to execute the computer program to implement:
• obtaining to-be-reported data;
• dividing the to-be-reported data into front string data and rear string data, wherein a length of the front string data is an integer multiple of the preset step, and the rear string data is data in the to-be-reported data other than the front string data;
• and
• separately scrambling, according to a preset scrambling algorithm, the front string data and the rear string data, to generate privacy data, and sending the privacy data to a server;
• and
• a sender, configured to send privacy data generated by the processor to a server.

A server, comprising:

• a receiver, configured to receive to-be-reported data sent by a terminal device;
• a memory, configured to store a computer program;
• a processor, configured to execute the computer program, to implement:
• receiving privacy data sent by a plurality of terminal devices;
• determining N pieces of first front string data, wherein a length of the first front string data is equal to an integer multiple of a preset step, and N is a positive integer;
• obtaining M pieces of to-be-reported data based on a plurality of pieces of privacy data, the N pieces of first front string data, and rear string data of different lengths;
• and
• determining reporting rates of the M pieces of to-be-reported data based on the plurality of pieces of privacy data, and determining to-be-reported data whose reporting rate is greater than a first preset value as target to-be-reported data.
