The invention includes systems and methods to asymmetrically encrypt audit logs, store a limited period of the encrypted audit logs, periodically send the encrypted audit logs to a central location for storage and further process in order to provide tamper-proof evidence of an activity. The system comprises a secure audit client enabled to perform various activities. A secure audit manager logs such activities in an audit log for uploading to a secure audit server. The secure audit server receives the audit logs from the secure audit manager. Finally a secure audit log consumer requests audit log data from the secure audit log manager to review the secure audit log.
