Why
encryption is necessary? |
 |
 |
 |
Do
you have your privacy information on your
computer?
Do
you have any confidential information in a
removable device?
Although
most computers have such important
information, it is not normally protected
correctly.
Provided
you have some privacy information on your
computer, if someone access it, or if the
computer is lost or stolen*, the information
in the vulnerable PC will be easily
accessed.
Provided
you carry a USB memory that has some
confidential information and if it is lost
or stolen, the information will be visible
to anybody.
If
you encrypt such information, even if it is
accessed by someone, it looks meaningless
encrypted data.

|
*
Over 1,700 computers are lost or stolen
every day and according to FBI, 97% are not
recovered.

A
person who often carries USB flash memories
CryptShield can encrypt whole USB flash memory. After
the encryption, even if you lose the flash memory, as it is encrypted; important data in the memory cannot be accessed by anyone.
A
person
who wants to have some files protected in the
PC
You
can create an encrypted virtual drive by CryptShield. Once the encrypted drive is created, no one can access the drive. The drive does not even appear in the system until it is mounted.
If you use a PC with other family members,
if you use CryptShield, you can hide an
encrypted volume and only when you need it, you can mount it to access files in the hidden volume.
A
person
who has many important files on
the computer and does not want anyone copy them
out
CryptShield can restrict the connection of removable devices by registering only accepted devices. If a non-registered device is connected by someone,
as it cannot be detected by the system, the
important files on the computer cannot be
taken out.

Encrypt
File Based Virtual Drives (Shielded File)
You
can create a hidden virtual drive from a
file.
Example: 1.
Create an encrypted file, abc.csd of
500MB. As it is encrypted, no one can see
the contents in it. (abc.csd looks
meaningless data)

2.
Mount the file to F: drive. 
3.
F: drive is a real drive that you can
access like other drives. 
4.
Unmount it when you do not use it. After
unmounting it, F: drive will be
disappeared automatically.
Please see
more information for CryptShield
Help.
Tips:
The shielded file can be shared with
others with the following ways.
1.
After mounting it, right click the mounted
drive to enable "Sharing and
Security...". Then you can share the
drive with other network PCs.
2.
You can send the shielded file (in this
case, abc.csd) by email. If the recipient
knows the password, he/she can access the
file.*
*
Recipient's computer needs CryptShield
installed.

Encrypt
Entire Storage Drives (Shielded Drive)
You
can create a hidden virtual drive from a
disk.
Example: 1.
Create an encrypted removable disk of 125MB. As it is encrypted, no one can see
the contents in it.

2.
Mount the drive to F: drive.
3.
F: drive is a real drive that you can
access like other drives. 
4.
Unmount it if you do not use it. After
unmounting it, F: drive will be
disappeared.

CryptShield
Functions: |
 |
-
Encryption
is on-the-fly and transparent to the legitimate user.
-
Performance is minimally
affected (just about 10%).
-
CryptShield
can create file based virtual drives (Shielded File) or entire physical
disks (Shielded Entire Drive) such as hard drives and removable devices as
encrypted drives. These volumes can be automatically or manually mounted.
You can add, modify, or delete any files or folders to these volumes as
normal disks.
-
CryptShield
can also make a removable disk shielded to be carried securely (Dynamic
Detection). The legitimate user can insert the
disk into another computer that does not have CryptShield installed. The system does an authentication check (password
mechanism) and if the authentication check is passed, the disk operates
normally.
-
Level of Security can be optimized to provide better IO performance. Security
is provided by “Encryption” with two types of 256 bit encryption
algorithms, Rijndael (AES) and Twofish (AES finalist) or one 448 bit
encryption algorithm of Blowfish.
-
CryptShield
can restrict the connection of removable devices by registering only
accepted devices. If a non-registered device is connected, it cannot be
detected by the system. There
is no limitation of registering the number of removable devices.
-
After
copying important files to the volume, you can delete the original files
completely by FileDeleter (right click). It is important because if
you do not operate such deletions, the files can be recovered by file recovery
software.
-
Activity
Log
password (require administrator right) will help you when you forget the password.
-
CryptShield
application itself is password protected so that only the legitimate user can operate it.
-
Easy
to access Shielded volumes by saving their information (Shielded List).
-
Auto
mount when application running.
-
Auto
unmount when Windows log off, application closed, or certain period of
inactivity.
-
Support
shielded drive share. You can share the Shielded drives after mounting
them.
