- Write User data
- Multimedia recording
Each of these security groups has one of 5 possible authorizations
levels (listed from the more restrictive to the more permissive):
- Never: The security group completely prevents access to the
protected features.
- Per use: Each time MIDlet tries to use protected feature, user is
prompted to grant access.
- Per session: First time a MIDlet uses a protected function, user is
prompted to grant access like in "Per use" authorization but
access is granted until the MIDlet terminates.
- Single confirmation: The first time in the whole MIDlet life a MIDlet
uses a protected feature, user is prompted to grant access. It
remains valid until the MIDlet is removed from the handset.
- Always: The security group unconditionally grants access to
protected features.
A MIDlet has a security status which is either "uncertified", or else
"certified".
An "uncertified" status means that the source of the MIDlet could
not be verified by the mobile phone at installation time. As far as the
phone knows, the MIDlet could have been written by anyone.
A "certified" status means that the MIDlet was digitally signed by a
known party, whose name is displayed by the mobile phone.
Security permissions are different for "uncertified" or "certified"
MIDlets.
Security configuration menu
When a MIDlet is installed in the mobile phone, default security
authorizations are applied.
This default security configuration may be altered through the
"Settings/Security" menu of an installed MIDlet.
Once in the "Security" menu, the security status of the MIDlet is displayed.
If you do not want to enter the security menu, simply select the
"Back" button. You can proceed by selecting "OK" button.
The menu displayed allows you to increase or decrease the
permissions currently applied to the current MIDlet for each of the
security groups.
