Secure Disc Capability

Fist of all we have to explain what is the SecurDisc capability our drive supports. SecurDisc is a technology which provides data protection and content access control on media throught an optical drive-software combined solution.

The function works with Nero and LG drives only, at least for now.

SecurDisc can be used with the following disc formats:

• CD-R, CD-RW
• DVD+R, DVD-R
• DVD+RW, DVD-RW
• DVD+R DL, DVD-R DL
• DVD-RAM

Now let's take a closer look at SecurDisc features:

1. Password Protection: Protects user data against unauthorized access through password protection. SecurDisc's password protection feature uses data encryption (AES-128) to restrict access to confidential files and folders.
2. Digital Signature: Provides origin of data through digital signature verification.
3. Data Integrity Check: Detects altered data through checksum verification.
4. Data Reliability: Maximazises data reliability via redundancy storage and defect data managment system.

In order to use the Secure Disc option, we had to install Nero 7 Essentials, which was included in the retail package of the LG drive. In the future, this plug-in will be incorporated in the Nero Full package.

Though Nero 7Essensials we may select burn Secure Disc Data CD or DVD.

Now here in this screen we add our data as we usually do when burning a CD/DVD disc with the diffrence that we select the two options, available on the left side of the program's window. (Protect Data Password & Digitally sign disc). We select the "Digitally sign disc" option and SecurDisc asks us to import our digital key and in case we don't have one, it guides us to push start button in order to create a new one.

We procceed by clicking next..

In the new key creation process, SecurDisc ask us to type some text in order to generate some random data and create our new key.

We name our new key ...

Back to the main screen with the difference that we have now our new key, ready to use..

We press ok and back to the main usual screen.. Now by the time we press next button the application asks us to create a password for our data .

As we can see the application examines and informs us how secure & strong our password is ....

and below ask us to reenter our password in order to confirm it.

Finally at the end of the procedure which is the usual we burn our disc. On average, SecurDisc recording time is longer than with a non SecurDisc optical drive. This is because SecurDisc always fills the CD or DVD completely, regardless of the size of data that you are copying. The additional information stored on the CD or DVD consists of redundancy and check-sum data, included in order to increase the chances of retrieving information in case your disc gets damaged. Also, some additional time is required to prepare SecurDisc files on the hard drive.

As we can see above our data have been digitally signed.

After our disc is burned we try to access our data ... but the SecurDisc asks us for the password as our data are protected :-)

Currently, only PDFs can be protected using the SecurDis feature. In order for you, or anyone else, to view a copy protected PDF, you require a special application called SecurDisc Viewer. SecurDisc Viewer can be downloaded free of charge at www.securdisc.net. PDFs that are copy protected using SecurDisc can only be read from the original DVD that was created. That means, if a SecurDisc copy protected PDF is copied to another media, it will no longer be readable, even with SecurDisc Viewer installed. In order to read a copy protected SecurDisc, a SecurDisc compatible drive is required.

To sum up, to take advantage of SecurDisc's features, you will need the following applications: Nero Express, to create SecurDiscs Nero InCD / InCD Reader, to access content on a SecurDisc SecurDisc Viewer, to view copy protected PDFs.

InCD Reader is available at www.SecurDisc.net.
