Abstract
The techniques described herein enable a user that sends an email message that includes encrypted content to define a time period during which a recipient of the encrypted content has decrypted access rights. To effectively define the time period, the user can set a time at which the decrypted access rights for the recipient expire. The time occurs after a time at which the email message is sent to the recipient. Upon expiration of the time period, the decrypted access rights to the encrypted content is revoked for the recipient of the email message, thereby providing a proactive element of security for confidential and/or sensitive information. Further, the techniques enable a user to revoke decrypted access rights to the encrypted content for a recipients at any given time after the email message has already been sent, thereby adding a reactive element of security for confidential and/or sensitive information.
