Phone security has always been an issue. Android allows multiple options to try and keep your device secure: face unlock with blinking, patterns, pins, etc. Most of these options will probably keep your device pretty secure, unless you run into Jason Bourne, or an experienced hacker. Even then, there are some pretty silly ways to get around these things like pictures or gifs for the face unlock, or looking for display smudges to crack your pattern. NFC Secure Beta intends to add another line of defense to keep your device secure.
From the developer:
Our goal for NFC Secure is not a public release on the Google Play Store. This app relies on some permissions not granted to userspace apps and thus requires root. While the app functions fine this way, having a rooted device would easily allow a hacker to simply remove the .apk file from the device. This is unfortunate, but not a real issue. The target audience for this app is a company providing devices to employees, able to modify the firmware before sending out secure devices, or OEMS looking to distinguish themselves the the security field. The possible uses for this are absolutely endless.
So, in other words, this app isn’t going to make your device that much more secure unless you’re able to modify your firmware. Therefore, unfortunately this app isn’t intended for mainstream use, but I think the NFC implementation is an awesome idea. The app itself is pretty simple. Once you get past the normal lock screen and whatever security measures you use there, the app enables and won’t allow anything further until you have your key, some NFC tag, unlock the device. If you’re worried about losing your NFC tag, bracelet etc., you can enable multiple keys to make sure you can always get to your device.
So what do you think of this idea? I think it’s awesome, and can’t wait to see where this goes. If you want to check it out, you can check out and download the app from the XDA thread here. Some users have reported some minor bugs if you check out the thread like the wallpaper disappearing after unlock, but nothing major. I also ran into this on my Nexus 7 running CM10.1. You obviously need to be rooted and have a device with NFC to give it a try. If you check it out, let us know how it goes, and be sure to let us know your thoughts on this by commenting below…
