Abstract
A system including a data retirement engine (DRE) and a method are provided for retiring sensitive data. The DRE receives a sensitive data map generated by a sensitive data discovery engine (SDDE) integrated to the DRE. The sensitive data map includes locations of sensitive data of different data types in multiple data stores. The DRE generates tokens for operational data from the sensitive data map based on selectable data classifications using one or more tokenizers that desensitize the sensitive data, while retaining transactional data. The DRE determines candidates from the operational data in an entirety of a target data store for the tokenization based on rules adjustably configured based on predetermined criteria. The DRE tokenizes the candidates using the tokens on the target data store and facilitates detokenization using a soft delete mode and deletion of the tokens using a hard delete mode.
