4. It is a device that allows its users to share files from
computer to computer without installing or configuring any
software or USB’s or the cables.
It provides a simple plug and play remote file access.
Bi-Directional File Access: connection between the 2
computers is completely symmetrical.

from IIT in Chennai and a Masters
degree from IISc in Bangalore.
FOUNDER & DESIGNER
iTwin is like the two ends of a cable, without the cable
5. 1. Plug iTwin into
USB port and share
your files and
folders.
2. Detach one half. 3.Plug that half into
another computer and
files are transferred
securely via internet.
6.
7.
8. 1. Back up your data from anywhere.
2. Don't pay for cloud storage. Don't
pay subscription fees for file
access.
3. You have all the storage you need on
your computer and home hard
drive.
4. Create your own personal cloud.
Secured by hardware-grade
encryption.
5. It is cross platform. Can work with
almost all present computer
operating systems.
With AES-256 hardware-
enabled encryption It's
as secure & simple.
9. Register for your iTwin disable
code.
Disable Code:
When you physically pair
two iTwin devices and
plug into a computer,
iTwin software requests
you to create an iTwin
Disable Code. It can be
think of as a suicide
trigger for the device. If
you lose one half of your
device, you simply provide
us this Disable code
(suicide trigger) and we
remotely disable your lost
half of your iTwin,
preventing any data loss.
10. 1. When you plug iTwin into a computer for the first time,
iTwin software gets installed on the computer.
2. Requires a min 512 MB.
3. Requires 15 MB hard-disk space.
4. USB 2.0 port
5. Requires broad-band Internet access 1Mbps upload speed
recommended.
6. Need administrator rights to access. Can be uninstalled.
7. Automatic Updates.
11. No Storage Limitations
1. iTwin does not store any of your data on itself. iTwin is a
data access device between two computers.
2. The only limit is the size of your computer's hard drive. If
you have a 1 TB hard-drive and desire to access it
completely, you can do so with iTwin.
3. Any network files folders that you can access from your
computer can be shared using iTwin. Network sharing.
4. No "Temp Files“ Unplug iTwin and all temp files are
purged automatically. This is especially useful when using
a computer that does not belong to you.
12. Size and weight
•Length : 3.54 inches
(90 mm).
•Width : 0.82 inch (21
mm).
•Depth : 0.314 inch
(8.0 mm).
•Weight : 0.11 pound
(50g).
Operating Requirements
•Operating temperature:
32° to 158° F (0° to 70° C).
•Relative humidity: 5% to
95% non-condensing.
•Maximum operating
altitude: 10,000 feet (3000
m).
13. LED Indicator
LED lights indicate status.
•Constant Blue light : iTwin is fully functional.
•Blinking Blue light : on-going data transfer.
•Constant red light : error.
Transfer Limits
1. Unlike many cloud based storage services, iTwin allows
you to transfer as much data as you want.
2. The only constraint is the limit of your ISP's bandwidth
allowances.
3. With iTwin, you don't need to worry about monthly
allowances or bandwidth limits when you transfer large files
online.
14. 1. iTwin detects almost all types of proxies, firewalls and
NATs and self-configures.
2. In case, one or both iTwin are not directly accessible
(behind firewalls), iTwin encrypted data traffic is
relayed through globally distributed servers. (amazon
EC2 based).
3. iTwin uses Amazon Web Services infrastructure with
99.5% availability to ensure fast, safe and secure data
relays.
15. 1. In case of Internet disruption, iTwin file transfers pause.
2. When the internet connection is resumed, iTwin software
continues the file transfer from where it left off.
3. iTwin's progress bar indicates the amount left to be
transferred.
1. All data is encrypted before it leaves your computer.
2. Your data remains encrypted until it reaches the
computer to which the second half of iTwin is attached.
3. Your data is never stored on any iTwin SERVER. Your
data is stored only on your computer.
16. 1. As doesn't store any data on itself. Your remote data
can only be accessed if you have the physical iTwin with
you. You can set up your iTwin to require a password.
2. Two iTwins together generate a random 256-bit AES
key, everytime they are physically paired and plugged
into a computer.
3. Advanced Encryption Standard (AES) 256 bit encryption is
used to protect all data communication & its standard has
not been broken so far and many consider AES to be
military grade.
17. 1. Passwords of any length can be set. iTwin's password is
stored on itself, not on any server.
2. If you forget your password, simply pair both halves of
your iTwin, plug them into a computer and set a new
password. No need for tech support!
18. 1. Two iTwins together generate a random 256-bit AES
key, every time they are physically paired and plugged
into a computer.
2. Smart Key generation is assisted by the computer to add
randomness.
3. Smart crypto key resides only on the two halves of the
paired iTwin.
4. Smart Crypto key is used for encrypting all data traffic
between two iTwins.
19.
20. 1. Before allowing any data transfer, every iTwin is
authenticated by iTwin's TwinTrust servers.
2. All communication between iTwin and TwinTrust is
secured using industry strength HTTPS (RSA 1024 bit,
128 bit RC4) protocol.
3. After successful authentication by TwinTrust,
TwinTrust assist iTwin to discover its other half.
4. After authenticating with TwinTrust, two halves of
iTwin mutually authenticate each other using their pre-
shared AES 256 bit crypto key.
5. If password is set, then verification is performed on
both iTwins before data transfer is initiated.
