From Indian minds comes Jarvis, an intelligent OS inspired by Iron Man

Personal technology has always been inspired by fiction. For instance, the world got its first glimpse of the mobile phone in the popular TV series Star Trek. Now, taking a cue from Iron Man, two young Indian technologists want to play Tony Stark and ask their computer to do stuff for them. To make things easy, their intelligent assistant is also called Jarvis after Stark’s virtual butler.

Delhi-based Chirag Dewan and Jaipur’s Himanshu Vaishnav, both computer science students in their early twenties, think their idea of artificial intelligence can change computing for ever. While start-ups the world over are working on solutions that make input methods for computing more natural, Jarvis Corp is working on an entire operating system that is fully automated and learns as it goes. Of course, it will interact with the user with the help of voice and gestures along with traditional input methods.

“From the origin of operating systems, everyone has been following the same thing. All of them have the same internal structure with a similar skin and flesh. With each new version of an operating system we are just seeing a new set of features being added to this legacy,” says Dewan, on a Skype call from the US. He says Jarvis is a totally redesigned OS. “We are not changing the paradigm, but we will change user experience for sure.”

New methods for password protection proposed

Researchers, including those of Indian-origin, have proposed a variety of innovative methods that can add a strong second layer of security to your password, protecting it from hackers.

Researchers from the University of Alabama at Birmingham, along with the University of California at Irvine, offered new options to increase password security against hacking.


"There have been many attacks on servers that store passwords lately, such as the breaches at PayPal and LinkedIn," said Nitesh Saxena, associate professor in the Department of Computer and Information Sciences at UAB.

Many people use the same few uncomplicated passwords repeatedly, making them easy to remember. Passwords are typically stored on servers in a hashed form.

Hackers can garner passwords either by an online brute-force attack, or by hacking a server with poor security and using a 'dictionary' of passwords to test offline.

Two-factor authentication schemes, such as Google Authenticator, or hardware tokens, such as RSA SecureID, use a second device to generate a temporary personal identification number, or PIN, that the user must enter along with their password.

But current two-factor schemes present the same vulnerabilities to server hacks as password-only authentication, Saxena said.

"If someone hacks into the server, they could learn the passwords via an offline dictionary attack," he said.


"Learning the passwords wouldn't compromise the second authentication factor, but the user might be using that same password elsewhere.


"The hacker might not be able to log into Facebook if Facebook uses two-factor authentication, but they could log into Twitter if Twitter uses the single-factor authentication using the same password," he said.

Researchers proposed and tested four two-factor schemes that require servers to store a randomised hash of the passwords and a second device, such as the user's security token or smartphone, to store a corresponding secret code.


They present these schemes at several levels of computer system bandwidth, effectively turning four schemes into 13 security options.

"Rather than requiring the user to enter both their password and a PIN generated by an app, the user could enter a password, and their smartphone could automatically send a PIN over a Bluetooth connection or through a simple QR code," Saxena said.


Saxena and his co-authors, UAB graduate student Maliheh Shirvanian, Stanislaw Jarecki and Naveen Nathan of the University of California at Irvine, have analysed each scheme in terms of security provided, usability and deployability.
