How to switch user profile based on password / lockscreen pattern

Currently, I have a family use tablet running on 4.2 Jellybean Model is [Ainol Novo7 Flame](http://www.ainol-novo.com/ainol-novo-7-flame-dual-core-1-5ghz-7-inch-1280-800-ips-screen-android-tablet.html) , a cheap Nexus7 alternative. Nexus7 is quite expensive in my country on its release so I bought this one instead. The problem is that the tablet is shared. I already set-up multi-user profiles for each of us. 1. Family mode 2. My mode 3. My sister's mode The default user set is family but I want it to automatically switch user-profiles based on the entered password or pattern lock. example: password 1358 triggers My mode while entering 2467 triggers My sister's mode profile I would also like to have an option to lock certain apps automatically when in family mode but unlocked in My mode Is there a way to do this? or is there an app that can closely do some of it?
