This option is only installed on EM-J2's that are sold to the Star Army of Yamatai. It was developed by collaboration between TC R&D, KFY. TC R&D provided the design for the module, interface and programming. The KFY created the interior based on the SACN Access Nodule.
The second function is to prevent the EM-J2 from storing sensitive data. When it is activated the EM-J2 will not store sensitive information to the permanent memory. Non-sensitive information will still be stored.
The J2-E3405 has to be authenticated by KFY personnel before it becomes operational.
Note: It essentially causes the android to redact the permanent record it keeps.
