Abstract:
A data processing method, device (600), and system, and information acquisition apparatus (201, 203, 205, 207). The method comprises: receiving target information acquired by an information acquisition apparatus (201, 203, 205, 207) (301); generating a data packet according to the target information (302); and digitally signing the generated data packet, and sending the same to a block chain network to write the target information into a block chain (303). By recording all city data information by means of a block chain, the method of the present invention ensures security and integrity of information storage, prevents information tampering, and improves information query efficiency. For information having a large data size, a hash value-based storage method is adopted to save memory space. In addition, an information query history is stored in a block chain to facilitate subsequent confirmation and queries, thus improving information security.
