MongoDB static desensitization method based on distributed computing

The invention discloses a MongoDB static desensitization method based on distributed computing. The MongoDB static desensitization method comprises the following steps that S1, task information is submitted to a master node; s2, after reading the task information, the master node performs type identification on the to-be-desensitized data, splits a desensitization task according to the identified to-be-desensitized data of different types and stores the desensitization task in a task queue; s3, the master node sends an instruction to an idle worker to allocate tasks to the worker, the worker reads data in a task queue, each worker reads one task for processing, and in the processing process, the worker sends heartbeat information to the master node at regular time; s4, the master node carries out distributed classified storage on the desensitized data; according to the method, before the data is distributed to the task queue, data type judgment is carried out on the fragment key of the data by range division
