The invention provides a data processing device and a data processing method. The device comprises a front-end system, an operation platform and a background core system. The front-end system is usedfor collecting data of each mechanism, performing format verification on the data of each mechanism, and generating a json file of each mechanism after the format verification is passed; and encrypting the generated json file of each mechanism, and uploading the encrypted json file to an operation platform. The operation platform is used for reading the encrypted json file of each mechanism, performing integrity check on the encrypted json file, and decrypting the encrypted json file when the integrity check is passed; and the operation platform is also used for carrying out data verificationon the decrypted json file, and sending the data of each mechanism to the background core system after the data verification is passed. According to the invention, automatic uploading, automatic dataverification, encryption and other processing of the data can be realized, automatic processing of the data is realized, and compared with manual processing, the efficiency is improved.
