Data processing method and system

A data processing method, comprising:

• providing a parallel computing system, wherein the parallel computing system comprises a mapper, a reducer, and at least an operation device, wherein the mapper receives a command and transmits a parallel computing input command corresponding to the command to the operation device, the operation device executes a calculation based on the parallel computing input command to generate an output result and transmits the output result to the reducer;
• providing a data transmitting interface, wherein the data transmitting interface is located between the mapper and the operation device, and the data transmitting interface is located between the operation device and the reducer, wherein following steps are executed via the data transmitting interface, comprising:
• intercepting the parallel computing input command transmitted from the mapper;
• determining whether the parallel computing input command is abnormal based on at least a security policy after receiving the parallel computing input command;
• transmitting the parallel computing input command to the operation device when the parallel computing input command is determined to be not abnormal;
• intercepting the output result transmitted from the operation device;
• determining whether the output result is abnormal based on the at least a security policy after receiving the output result;
• and
• transmitting the output result to the reducer when the output result is determined to be not abnormal.
