System and method for on-demand data cleansing

A system for on-demand data cleansing, comprising:

• a processor;
• a volatile memory communicatively coupled to the processor and comprising a data object having a plurality of data fields, each field having a tag and a value;
• cleansing module stored in the volatile memory and executed by the processor, the cleansing module comprising a library having a plurality of tag-operation pairs, each tag-operation pair comprising a library tag and an associated operation, the cleansing module configured to receive a pointer locating the data object within volatile memory, and further configured to, for each data field of the plurality of data fields:
• look up the tag of the data field among the library tags of the plurality of tag-operation pairs of the library;
• and
• execute the operation paired with the matching library tag on the value of the data field, modifying the value of the data field while it is stored in volatile memory;
• wherein, for each tag-operation pair of the library, the operation defines logic whose execution will bring information described by the paired library tag into compliance with a policy;
• wherein the cleansing module is configured to execute the operation by evaluating, at runtime, a string defining operation logic and stored in the tag-operation pair;
• and
• wherein the looking up of the tag within the library, and the executing of the operation is performed in near real-time.
