Android Upgraded Face Unlock - Liveness Check - to Access Secure

Android 4.0's "Face Unlock" features in which the phone's camera scan your face for a seconds, then compares it to series of previously clicked photo of true owner's face. Whether if it gets the match, then it's done You are zipped to the homescreen, no PIN required.But it is also very easy to trick the app with something as simple as a printed photo of the phone's true owner.

Now, Android 4.1 Jelly Bean latest upgraded version takes this idea to the next level by verifying that the face used to unlock the phone is actually that of a living, breathing human who is it's true owner.

According to a droid user on Android developer forum, the new version of Face Unlock first verifies the user's identity, and then requires them to blink after the initial scan before the phone unlocks itself. The feature is called by the name "Liveness Check" — means that no other stuffs can be used to peep an owner's phone.

A group of droid users demonstrated via YouTube how to get pass the past check with a photo previously taken by true owner's.

The Trick is simple: Find a relatively clear photo of your mark, use a photo editor to cover his or her eyes with their respective skin tone, and flash the original and modified images on a monitor. Point the Jelly Bean device towards the monitor, flip the images when directed, and bang - unrestricted access.

But despite this new layer of security, It is still advisable to use something a bit more secure by lengthy, complex password in order to lock up your sensitive information.

Egg Membrane as a new Biological dressing

An article I found online is attempted to determine the effectiveness of egg membranes as a new biological dressing to promote infection-free healing and provide pain relief. It sounds little bit wierd, but Yes egg membranes can be used to stop bleeding and prevent the wounds until you get to emergency room for medical attention. 

While the Egg membrane protects the chicken embryo wall during its grooving process, this thin tissue is containing mainly glycoprotein without cellular components. Therefor the eggshell membrane is not taken up by the wound and theoretically could be a good material for skin donor units coverage. It appeared that the parts coated with egg membrane were the ones who healed most recently. 

Results of this study showed that the egg membrane may be an ideal skin graft donor bandage, as it possesses qualities of pain relief, wound protection, promotion of healing, and low cost comparing to all the other medical treatments applied.

if you don't have any sterile bandages on hand it's an alternative worth considering. It might be difficult to remove the membrane from shell for first time, so give it a try.
