5. ABSTRACT
A USB flash drive is a data storage device that consists of flash memory
with an integrated Universal Serial Bus (USB) interface. A Cloud Storage is also
a similar case where in the data is stored remotely and is accessed whenever
needed. But a drawback of this USB flash drives is its small size cause of
which it can easily be misplaced or lost. This is a particular problem if the data
it contains is sensitive and confidential. In Cloud Storages the data can be
stolen or misused if the username and password of an account to access the
storage is hacked by someone. There are many more drawbacks like limited
storage, no security, back up, temp files, no remote disable etc.
i-Twin is a 'limitless' secure USB device that enables users to access, edit
& share all their files & media between any two online computers anywhere in
the world. The only limit is the size of your computer’s hard drive. i-Twin is an
innovative solution that allows remote file access without the security and
privacy risks of the cloud and USB flash drives. It’s very easy to access as a
USB device and no special installation is required. i-Twin uses thoroughly
analyzed crypto protocols and algorithms(AES 256 bit encryption). It has
features like bi-directional file access, no temp files, remote disable, smart key
generation, password support and twin trust authentication.

CHAPTER-1
INTRODUCTION
i-Twin is a revolutionary new file sharing and remote access device
brought to you by a company called i-Twin. It's like two ends of a cable,
without the cable. It's as simple to use as a flash drive. It’s literally plug and
play.
i-Twin can connect any two online computers anywhere in the world. i-
Twin enables you to have access to any or all of your home computer's files and
folders while you're on-the-go. Similarly, you can also use i-Twin to access to
any or all of your office computer's files and folders while on-the-go. There's no
in-built limit to the amount of storage you can access with i-Twin while you're
on-the-go. The only limit is the size of your hard drives. The only other "limit" is
the speed of your Internet connection. The faster it is, the better your
experience.
You can select files for accessing later on-the-go, or you can edit them
remotely, without the files leaving your computer. You can also back-up files to
your home or office computer while you're out on-the-go. It's so easy, it's
unbelievable.

1.1 HISTORY
i-Twin was invented by an Indian named Lux Anantharaman. After
achieving a Bachelors degree in Electrical and Electronic Engineering from IIT
in Chennai and a Masters degree from IISc in Bangalore, Lux worked first as
an IT security researcher at the Institute of Systems Science, Singapore and
then as senior researcher at Kent Ridge Digital Labs and the Institute for
Infocomm Research. Lux specializes in PKI implementations, efficient digital
certificate revocations and usable security. Lux was pursuing a part-time MBA
at NUS Business School, Singapore, but put studies on hold because of
potential of i-Twin.
Lux Anantharaman (Founder and Designer)
Electrical and Electronics Engineering from
Chennai and a master’s degree from IISC in
Bangalore.
He says i-Twin is like the two ends of a cable,
without a cable.

CHAPTER-2
WORKING OF i-TWIN
Fig 2: How to use i-Twin
 When you connect i-Twin, you'll see a regular window pop-up, just as you
would if you plugged in a regular USB flash drive.
 Drag and drop files and folders into this window to share them - as many as
you want. Leave your computer with one half of i-Twin connected to it.
 Detach the other half of i-Twin and take it with you.
 Wherever you go, you can remotely access the shared files, simply by
plugging the half you are carrying into any online Windows computer,
anywhere.
 i-Twin allows you to transfer files to - or from - your home computer. Or
your office computer. Or your friend's, or your colleague's! i-Twin also allows
you to edit the shared files on a remote computer, while keeping them on
that remote computer, (no need to transfer those files before you edit them).

CHAPTER-3
FEATURES OF i-TWIN
 Like A Limitless Capacity Secure USB Drive
i-Twin allows you to securely access your entire hard drive. It's as
if you are carrying an access-key to all your files in a device that fits in
the palm of your hand. And unlike portable storage, i-Twin lets your data
stay safely at home (or in the office).
 Remotely edit shared files
Remotely edit any shared file from any location. i-Twin allows you
to keep a single version on one computer, with you and your chosen i-
Twin partner collaborating directly on this version. Say goodbye to
multiple versions of files flying around by email.
 Backup your data from anywhere
When you are on the road, you can use i-Twin to move copies of
files from your laptop to your home or office computer. If you are
traveling and taking lots of pictures, you can free up your SD card by
moving files onto your laptop and transferring them back home. It keeps
your data safe and secure.
 One-time cost. No fees, ever
Don't pay for cloud storage. Don't pay subscription fees for file
access. Don't get locked in. You have all the storage you need on your
computer and home hard drive. With i-Twin, share it and access it from
anywhere.

11. i-Twin Technology
Dept. of E.C.E, RGMCET-Nandyal Page 5
 Data Security
i-Twin doesn't store any data on itself. It just enables a secure connection
between two computers. Your remote data can only be accessed if you have
the physical i-Twin with you. Additionally, you can set up your i-Twin to
require a password. i-Twin includes a feature that allows you to remotely
disable the connection should you lose your remote i-Twin half. So you can
rest assured that your data is safe, even if you lose your i-Twin device. If you
have ever lost a portable memory device, you know that terrible feeling. We
want to make sure this never happens to you again. It even makes use of AES
(256 bit key encryption) in order to transfer the data from one computer to
another.

CHAPTER-4
DETAILED AUTHENTICATION PROCESS
 Before allowing any data transfer every i-Twin is authenticated by i-
Twins Twin Trust Services.
 All communications between the i-Twin are i-Twin Trust is secured using
industry strength HTTPs (RSA1024 bits, 128 bits RC4) protocol.
 After successful authentication by Twin Trust assist i-Twin to discover its
other half.
 After authentication with Twin Trust, two halves of i-Twin mutually
authenticated each other using pre-shared AES 256 bit crypto key.
 If password is set, then verification is performed on both i-Twins before
data transfer is initiated.

CHAPTER-6
6.1 ADVANTAGES
 Smart key generation
Two i-Twins together generate a random 256-bit AES key, every
time they are physically paired and plugged into a computer. Smart Key
generation is assisted by the computer to add randomness. Smart crypto
key resides only on the two halves of the paired i-Twin. Smart Crypto key
is used for encrypting all data traffic between two i-Twins.
 No “Temp Files”
Unplug i-Twin and all temp files are purged automatically. This is
especially useful when using a computer that does not belong to you.
 Password support
i-Twin even provides password support. Passwords of any length
can be set. Unlike other web services, i-Twin's password is stored on
itself, not on any server. If you forget your password, simply pair both
halves of your i-Twin, plug them into a computer and set a new
password. No need for tech support!
 Bi-Directional File Access
When using i-Twin, the connection between the 2 computers is
completely symmetrical. Access, copy, backup & remotely edit files on
computer A from computer B, and on B from A. You will have access to
files on both A and B.

 i-Twin is like the two ends of a cable, without the cable.
i-Twin is just like a wireless device connecting two systems and securely
transferring data between them.
