Data storage and removal

A computer implemented system for data storage and removal comprising instructions for:

• providing databases, where each database is associated with a database time period;
• providing encryption keys, where each encryption key is associated with an encryption time period;
• receiving data items;
• encrypting each data item using the encryption key associated with the encryption time period that corresponds to a time associated with the data item;
• storing each encrypted data item in the database associated with the database time period that corresponds to the time associated with the data item;
• deactivating each encryption key at a predetermined time after the associated encryption time period ends;
• and,
• making each database irretrievable upon a determination that all of the encryption keys associated with the data items stored in that database have been deactivated.
