how we can track changes of email addresses in the security console ?

in HCM Console security admins can make some edits in the security console including users email addresses using the following steps :
Open the Security Console by clicking the Security Console link under the Tools heading in the Navigator. Click the user name link. On the User Account Details window, click Edit. In the Edit User Account window, edit the email address.

for audit purposes we would like track through a report or an extraction those email addresses changes "from to" and who made the changes and on which date ?
