Abstract
A system and method for data storage and removal includes providing databases and providing encryption keys. Each database is associated with a database time period and each encryption key is associated with an encryption time period. Data items are received and each data item is encrypted using the encryption key associated with the encryption time period that corresponds to a time associated with the data item. Each encrypted data item is stored in the database associated with the database time period that corresponds to the time associated with the data item. Each encryption key is deactivated at a predetermined time after the associated encryption time period ends. Each database is made irretrievable upon a determination that all of the encryption keys associated with the data items stored in that database have been deactivated.
