This document summarizes a technical presentation on iTwin, a device that allows users to share files between computers without installing software or using USB drives or cables. iTwin uses AES 256-bit encryption and provides limitless secure storage that can be accessed from any computer. It has advantages over USB drives like remote disabling if lost and no temp files, and over cloud storage by allowing direct editing of remote files and having no storage limits or fees. The presentation provides details on iTwin's functions, technology, system requirements and comparisons with other technologies. It concludes that iTwin is a simple and inexpensive solution for remotely accessing and updating files between computers.

4. Present Drawbacks
 Drawback of USB flash drives is it’s small size
cause of which it can easily be misplaced or lost.
 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.

8. Introduction
 iTwin 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.
 iTwin uses thoroughly analyzed crypto protocols and
algorithms(AES 256 bit encryption). 8 March 20158

12. Technology
 AES (Advanced Encryption Standard) - Established by
the U.S NIST in 2001.
 AES is a symmetric-key algorithm.
 AES is a variant of encryption family which has fixed
block size of 128,192, or 256-bits.
 AES operates on a 4*4 matrix of bytes, termed as ‘state’
.
 Key size used for an AES cryptograph specifies the
number of repetitions of transformation rounds that are
required to convert input in plain text into output in
cryptograph text. 8 March 201512

13. i-Twin vs USB
iTwin USB
Price
$ 99. $120 (approx.) for 64GB.
Capacity Access to computer's entire hard drive
& any attached storage.
2GB to 256GB (depending on model).
Remote Disable If you lose one half, you can remotely
disable it.
If you lose the device, you lose and
expose your data.
Data Encryption
AES 256-bit.
Standard USB devices don't support
encryption. Need additional software.
Creation of 2nd copy
of file
You can edit remote files directly,
with no additional copy created.
Yes. This leads to confusion due to
multiple versions of the same file.

14. i-Twin vs Cloud storage
iTwin Cloud Storage
Ease of Installation Plug 'n' Play,
install & configure it. Need to
create, remember & use login.
Storage Limit & Monthly Fees No storage limit and fee required Has storage limits and fee.
Security & Privacy
Hardware based security plus
optional password & remote
disable
Password only.
Remote Editing
Directly edit your home/office
files remotely,
Remote editing requires 2nd
copy to be created on other
computers.
Accidental Delete Protection Present. Not present
