a memory configured to store one or more data elements; and
a controller coupled to the memory and configured to:
receive indication of data to be anonymized;
receive, from among the one or more data elements, a data element to be stored;
parse the data element to find one or more data portions to be anonymized;
generate a first copy of the one or more data portions to be anonymized;
delete the one or more data portions to be anonymized from the data element to be stored to generate a modified data element to be stored;
generate a second copy of the modified data element utilizing deduplication;
