A user retains access to a document previously generated or received by an institution system and stored in encrypted form in storage of the institution system or another entity associated with the institution system. However, the institution system does not have access to the document (in readable form) after an expiration of an amount of time. The document is encrypted in such a manner that only the user can decrypt the document, but the institution system cannot decrypt it. In this manner, the institution system may meet business or regulatory requirements or policies directed to discarding (i.e., purging) the document after a predetermined amount of time, but can still provide secure storage of the document in encrypted form to the user independent of the business or regulatory requirements or policies that mandate purging the document. |
