Biwota Cerbero|工具線上App不用買-HotApp4Game

*** Important ***

No application is allowed to mess with the default lock screen unless it has root access. This is not a replacement lock screen unless you disable your current one. It can also be used as an additional layer of security.

** About ***

Biwota Cerbero is an additional layer (or single layer, if you choose to rely on it) of security for your Android Device. It locks the screen, and unlocks it using Near-Field Communication (NFC) Technology. This means that unless you have a registered NFC Tag for the Device, it cannot be unlocked. (However, recovery is still possible if you lock yourself out).

All you need is an NFC Tag; you can find these in rail cards, smartcards, passports, university IDs, etc. Biwota Cerbero does not store this information externally in any way, and only stores the ID blocks of the NFC Tag .

The NFC tag is not written, altered or formatted in any way, so it is safe to use your everyday ID card. You can verify this by using an NFC Tag Info App by the company that makes most smartcards (NXP Communications) and comparing the xml files generated.

Feedback would be wonderful, and I will try to improve the application as much as possible. Email: apps.android@biwota.com

*** Permissions ***

- CONTROL NEAR FIELD COMMUNICATION. The application needs to use Near-Field Communication to detect smartcards and other NFC tags.

- FULL INTERNET ACCESS. It is needed to show the (small) advertisement in the main menu. Any internet use in an application requires this permission.

- READ PHONE STATE AND IDENTITY. This is a security measure; the screen lock can be circumvented by calling the device (Try this with the normal lock. Calling the device disables the lock), so Cerbero re-locks the screen after a call.

- VIEW NETWORK STATE. It allows Cerbero to improve your user experience by checking Internet access before showing the advertisement. This stops the application hanging if, say, you have a poor data connection.

- AUTOMATICALLY START AT BOOT. The application needs to know when the device boots for Cerbero to lock it. Otherwise, you could just turn the phone off and on and gain access. Every Android Device has a "magic combination" of keys to access power options.

- MARKET BILLING SERVICE. Needed to access Google Play for the premium version.

*** To get the Premium Version ***

Run the application and scroll down the main menu. Press "Get Cerbero Premium" and follow the instructions from Google Play.

*** To Remove ***

We hope that you like Biwota Cerbero, and that you don't want to remove it. If you need to, however, you must remove it from Device administrators (If you have registered it as one). You must go to your device settings, and click Security > Device administrators. Biwota Cerbero will be listed; simply uncheck it and confirm. After this, you should be able to uninstall Biwota Cerbero the same as any other application.
