There are a few ways to delete anonymized data. One way is to use the Data Protection Officer (DPO) in your organization’s governing body. The DPO can help you to delete anonymized data if it is not needed for the purposes for which it was collected or if it is no longer necessary for the organization’s operations. Another way to delete anonymized data is to use the Data Erasure Tool (DET). DET can be used to erase all traces of an individual’s identity from any data, including anonymized data.
