A unique system has been designed by researchers that will encrypt software in order to make it impervious to reverse-engineering. UCLA computer science professor Amit Sahaiand a team of researchers have developed a system which will only allow someone to use a programme as intended, while preventing any deciphering of the code behind it. This is known as software obfuscation in computer science and it is the first time it has been accomplished. Sahai said that the new system puts up an iron wall making it impossible for an adversary to reverse-engineer the software without solving mathematical problems that take hundreds of years to work out on today's computers. The researchers said their mathematical obfuscation mechanism can be used to protectintellectual property by preventing the theft of new algorithms and by hiding the vulnerability a software patch is designed to repair when the patch is distributed.

Rarely does a week go by without news of another hacking incident, whether it's Chinese hackers accused of breaking in to The New York Times' computer systems or Burger King finding its Twitter account taken over by pranksters. Security threats aren't new and have long been part of online life. But the increased attention on them makes now a good time to review ways you can protect yourself. If nothing here feels new, that's good, as it means you've been doing the things you need to do to keep your accounts safe from hackers. Although there's no way to completely eliminate threats, minimizing them will go a long way. One of the best things you can do is to make sure your password is strong. If someone's able to guess the password to your email or Facebook account, that person can post or send embarrassing things on your behalf. Someone was able to access Burger King's Twitter account recently and changed its profile picture to a M...
