לאחרונה נתקלתי בפרסומים וכתבות אודות הצורבים החדשים של lg עם פטנט ה-securedisk

ובעיקר על "ספינת הדגל " h55l.

האם באמת מדובר בשיפור משמעותי ללקוח מבחינת אמינות הצריבה ,הגיבוי והשמירה על הנתונים באמצעות הצפנה מקצועית או שמדובר בסך הכול בעוד גימיק שיווקי מסחרי ותו לא ?

[attachment deleted by admin]

ברור שזה גימיק, בעבר צורבים היו ניבדלים זה מזה במהירות הצריבה, כיום, שמהירות הצריבה היא לא פקטור משמעותי, צריך דברים אחרים בכדי לעשות עליהם את הספין התקשורתי שיבדיל את הצורבים זה מזה - זוהי ההגדרה של גימיק.

תחשוב על זה ככה:

חברות מוסיקה וסרטים הגדולות בעולם לא יכולות להגן על הייצירות שלהם, מה אתה כבר תוכל לעשות?

שמעו גם אני סקפטי ,אבל קשה לי להאמין שכל ההיפ סביב הצורב החדש הזה של LG הוא לגמרי משולל יסוד .להלן כמה קישורים ודעות על הצורב הזה שאני מניח אתם עוד לא מכירים.

אנא מכם קודם תקראו על הצורב ורק אחר כך תאמרו לי מה אתם חושבים .

יש לקחת בחשבון שהצורב החדש הזה הוא לא יותר יקר מצורבים של חברות אחרות והוא גם

Sata וגם ,תומך ב- lightscribe (נכון שכרגע מדיות שמאימות ל- lightscribe הן יקרות יחסית ולא כדאיות , כאשר אפשר לקחת טוש ולכתוב ישר על המדייה ,אבל להערכתי המדיות שמתאימות ל- lightscribe ירדו משמעותית בזמן הקרוב כשהתכונה הזאת תהפוך לסטנדט נפוץ ובסופו של דבר שההפרש יהיה כל כך זניח שיהיה חבל לא לצרוב על מדיות כאלו .

( אל תשכחו את החיסרון המהותי של שימוש בטוש לא מחיק מבוסס אלכוהול והוא שהכיתוב הידני דוהה מיטשטש ונעלם עם הזמן )

How to protect your data with SecurDisc

SecurDisc protects your valuable and confidential files through a range of security options you control.

Discover how SecurDisc overcomes common security problems.

Security problem #1:

How do I prevent unwanted access to my files?

I have confidential data I want to keep away from prying eyes.

SecurDisc Solution: Password Protection

SecurDisc allows you to create a password-protected disc, meaning that anyone wanting to view the contents of your files and folders must enter the correct password in order to do so. Since you set the password and you control who receives this password, you can feel safe knowing that access to your critical information is restricted.

Security problem #2:

How can I transfer sensitive data?

I need to securely transfer highly sensitive, confidential information to another party, and I want to be confident that even if I lose a disc, the information will remain secure.

SecurDisc Solution: Digital Signature

SecurDisc lets you sign a disc to ensure that the information is valid and has not been manipulated in anyway. A doctor, for example, can digitally sign confidential medical files, and then distribute a public key to the disc's recipients. The recipients can then use the key to verify the authenticity of the disc's contents and ensure they are receiving accurate, non-tampered data.

Security problem #3:

How do I retrieve data from damaged discs?

I want to be able to retrieve my files if a disc is accidentally damaged.

SecurDisc Solution: Data Reliability

After you've copied all your files onto a disc, SecurDisc uses the empty space to add redundant and checksum data. This significantly increases the chances of your files being retrieved, even if the disc itself is damaged.

Security problem #4:

How can I preserve my important data over time?

Knowing that discs decay over time or can be scratched, I want to ensure that the family photos and videos I record to CDs and DVDs are preserved for years to come and don't become unreadable.

SecurDisc Solution: Data Integrity Check

While nothing can prevent disc decay, SecurDisc can save your data by notifying you that it is in danger of being lost forever, giving you time to back it up to another disc.

Security problem #5:

How can I prevent unwanted copying of my files?

I have confidential information stored in PDF format on a DVD that I want people to be able to view, but not copy to another disc or computer.

SecurDisc Solution: Copy Protection for PDF Files

SecurDisc ensures that the only way to read confidential files is with the original DVD you save it to, meaning you control the distribution of this information.

Photographer uses SecurDisc to recover irreplaceable memories from a damaged disc

Protect the readability of files from disc decay

Phil Stamp is a keen amateur photographer who takes thousands of digital photos of family, friends, and other subjects. Because he doesn't want to use up all the space on his computer by storing photos on his hard drive, Phil burns his images to DVDs.

In order to preserve the quality and readability of his precious photos he uses a SecurDisc-enabled drive to record his files to DVDs. The Data Integrity feature built into SecurDisc protects his images against disc decay, which can affect the readability of data on discs over time.

The Data Integrity checker informs Phil if his images are in danger, allowing him to save them to another disc and preserve his priceless memories forever.

Recover valuable data from a damaged disc

While Phil has done everything he can to protect the images he saves to DVDs from disc decay, sometimes discs get damaged in other ways.

One day Phil discovered that one of his DVDs had been so badly scratched, he couldn't access the files on it. However, because he had burned it with a SecurDisc-enabled drive, he was able to recover all of his irreplaceable images thanks to the SecurDisc Data Reliability feature.

This feature uses the space left over on the DVD after Phil had saved his photos, to store redundant and checksum data. The chances of retrieving data from a damaged disc are much higher with SecurDisc. And so it turned out for Phil -- much to his relief!

Business partners secure their confidential data with SecurDisc Testimonials

Exchange confidential information safely

Andrea Smith and John Millar have a unique idea for a new business partnership. And, of course, they want to keep their idea under wraps until they're ready to launch. Worried about the security of their documents, they use SecurDisc-protected CDs to exchange files and documents, such as business plan drafts and budget information.

They burn data to CDs using NeroExpress and a SecurDisc drive, and activate the Password Protection feature. Each recipient needs just the password and the InCD Reader to access the disc. If the recipient doesn't have the InCD Reader, when the CD is launched, a message appears that tells the user where to download InCD Reader.

Andrea and John use SecurDisc to backup all their documents to DVDs, and password-protect them all in case they are lost or stolen. This helps Andrea and John safeguard all of their valuable information.

Digitally sign discs to prove their authenticity

As well as password-protecting their data, Andrea and John further protect their confidential files by digitally signing every disc they record with SecurDisc. This allows recipients to verify that the information they receive is authentic, and hasn't been tampered with in any way.

SecurDisc does this by generating a private and public key for each disc. Either Andrea or John holds the private key, and give the recipient of the disc the public key. The recipient uses the InCD Reader, which can be downloaded for free to check the authenticity of the disc with the public key.

This way, SecurDisc lets Andrea and John securely pass sensitive information between themselves and others with confidence.

Protect PDF files from unwanted copying and sharing

When Andrea and John have finished their business plan, they save it as a PDF file. They want to show the plan to a few people, but want to make sure it isn't copied and distributed to anyone else.

Using SecurDisc's Copy Protection feature, they ensure that the document can only be read from the original SecurDisc DVD they save it to. This means that the file cannot be copied or edited in any way - giving them peace of mind that the information in their business plan won't be copied and shared with others.

Testimonials

"There's so much piracy and illegal copying going about, it makes sense to make sure no-one can take all our work and pass it off as their own. SecurDisc's Copy Protection is perfect for making sure no one reproduces our info." - Andrea

"Without SecurDisc I never would have known that my disc of photos was decaying, and I would have lost hundreds of holiday photos. There's no way I could have replaced them." - Phil

"SecurDisc is priceless! Money can't replace personal photos, so I can't put a value on how much SecurDisc saved me by restoring all my photos from a damaged disc." - Julia

"SecurDisc means I can relax, knowing that if I lose a disc or someone breaks into the office, all our confidential, backed-up files are safe." - Jamie

"Being able to digitally sign our discs means I can pass documents to my business partner, and she knows it hasn't been altered by someone else." - John

Secure the files you store on CDs and DVDs against damage, theft and copying

How secure are the files you record to CDs and DVDs?

These days most people password-protect or encrypt their hard drive, but the data stored on your CDs and DVDs is even more vulnerable to theft, loss, damage, unauthorized access and copying.

Copy Protection Prevent copying of PDF documents.

Your data is your business. Securing it is ours.

SecurDisc is a breakthrough in optical media security at a time when computer users are storing increasing amounts of confidential and important data on CDs and DVDs.

Developed by Nero and Hitachi-LG-Data-Storage (HLDS), SecurDisc provides a full range of powerful security features that protect data stored on optical media against unauthorized access and copying, and helps you recover it in the event of disc failure. SecurDisc also helps ensure the integrity and reliability of data stored on CDs and DVDs over long periods of time.

Learn more about the technology driving SecurDisc's five security features:

1. Data Reliability to save your data if a disc is damaged

2. Password Protection to stop unwanted access to your data

3. Data Integrity Check to preserve your data over time

4. Digital Signature to verify the authenticity of your files

5. Copy Protection to stop unwanted copying of PDF files

Data Reliability helps rescue data from a damaged disc

While media capacity has become less expensive, reliability is still very important for today's optical storage media as discs can be scratched or otherwise damaged. SecurDisc significantly increases your chances of retrieving data from a damaged disc.

When you record data to optical media, the discs rarely fill up to their capacity. In fact, often a considerable amount of space remains unused.

SecurDisc redundantly stores information in the remaining space to safeguard your files in case the disc gets damaged. This feature is vital to the security of your files, so Data Reliability is always enabled and cannot be disabled.

Password Protection keeps away prying eyes

SecurDisc ensures the protection of confidential data by encrypting through AES-128. This prohibits access to the protected data without the password set by the original author.

When a user attempts to access password-protected data, a password prompt appears. The password is then passed to the drive through a secure channel. The drive checks the password and grants access to the protected data if it is the correct one.

SecurDisc is a hardware-software based solution, and is therefore harder to hack and more secure than software-only solutions. Not only is the password protection feature secured by the AES-128 encryption, but secret values are also implemented in a drive's firmware to provide extra security.

The password should be at least 16 characters long. Alternatively, complete sentences can be used.

Data Integrity Check protects your data from disc decay

SecurDisc provides another layer of protection through its Data Integrity Check, which warns you if the data on a disc is at risk of disc decay, giving you time to back it up to another disc.

This is accomplished by using the checksum feature. As another core security feature, Data Integrity Check is always enabled and cannot be disabled.

Digital Signature verifies the authenticity of your files

When you transfer important data from one person to another, the recipient must be able to tell that the data is authentic and has not been manipulated.

To do so, SecurDisc lets you digitally sign an entire SecurDisc disc using a trusted signing key. You can then distribute a signature verification key to anyone who receives the disc, allowing them to verify the authenticity of the data.

A private key is used for the digital signature, and the recipient verifies it using the corresponding public key. If you don't have a private-public key pair you can create one within Nero Express.

The recipient needs either InCD or InCD Reader to verify the signature using the public key, which can be downloaded here

Copy Protection prohibits PDF files replication

SecurDisc can also protect sensitive data against unauthorized duplication - allowing data to be read, but not copied or edited.

SecurDisc encrypts files and stores the keys on a copy-protected part of the media. This feature is currently only available for PDFs recorded to DVDs.

A viewer application combined with a SecurDisc drive is required to view protected files.

Look for the logo: What you need to use SecurDisc

To take full advantage of SecurDisc's features, you need a SecurDisc enabled optical drive. Look for the SecurDisc logo on optical drives to be sure your files will be protected.

The LG Super Multi Drive with SecurDisc is the world's first to support all DVD formats, and it protects your files with SecurDisc. It also offers the fastest DVD+/- write speed and incorporates LightScribe technology to print labels onto your discs.

"By adding copy protection, Nero has recognized a critical growing need and satisfied it with a cutting-edge feature that is sure to meet the needs of users in every field, as well as raise awareness of the importance of document security."

The new LG DVD Rewriter provides the ultimate defense against unauthorized access and unauthorized manipulation of sensitive data

Reaffirming its position as the global leader in optical storage drives, LG Electronics announces the XX market availability of Security Function added Super Multi DVD Rewriter. LGs new Super Multi DVD Rewriter, featuring SecurDisc technology, meets the markets need for high secure data protection and content access control when writing data in CD and DVD formats.

Super Multi DVD Rewriter featuring SecurDisc technology, GSA-H55N/L provides both professional and private users with the means necessary to protect and share data securely. While some optical disc drives support password encryption as the only security function, GSA-H55N/L offers five features to protect a disc at the user and storage level using SecurDisc technology, co-developed with Nero.

1. Password Protection

Protects user data against unauthorized access through password protection

2. Digital Signature

SecurDisc Technology Preview

SecurDisc Intro

________________________________________

One of the biggest concerns in the computer industry today is data security. Every few weeks, you hear about an employee at some company losing a laptop containing confidential information about its employees or customers. Drive encryption has been a popular solution to this problem. Without the correct key or password, the data can't be accessed by potential data thieves, even if the hard drive is moved to another computer.

While hard drive encryption may let laptop owners sleep a little more soundly at night, those that backup their data to CD or DVD still run the risk of data theft. When burned to disc, the files are usually not encrypted. If left out in the open or not disposed of correctly, a disc, and the data on it, could land in the hands of criminals.

LG Electronics and Nero are trying to tackle this problem with their new SecurDisc technology. Unveiled at this year's Consumer Electronics Show, SecurDisc protects data on optical media at both the user and storage levels. At the user level, it uses password protection and AES-128 encryption to prevent unauthorized access. While this concept is nothing new, SecurDisc adds an extra layer of security by utilizing a hardware and software-based solution. To prevent modification, a digital signature can be applied to data so that its authenticity can be verified.

At the storage level, SecurDisc uses checksums to verify data integrity and readability. Using this feature, you can check to see if your data has been altered due to the physical decay of the media. SecurDisc also increases reliability through a redundancy-based defect management system. By fully utilizing the empty space on a disc, the technology can greatly increase your chances of reading a damaged disc.

In future versions of Nero, SecurDisc will also let you copy protect PDF files. In order to view a copy protected PDF, you'll need a special application called SecurDisc Viewer and a SecurDisc ready drive. Copy protected PDF's can only be read from the original DVD and cannot be copied to other media without the correct duplication password.

At CES, LG unveiled their first SecurDisc ready drives, the GSA-H55N and GSA-H55L. Both of these "Super-Multi" drives feature 20x DVD±R, 10x DVD±R DL and 12x DVD-RAM writing speeds and, in the case of the GSA-H55L, support for HP's LightScribe Direct Disc Labeling system. While these drives won't ship in the US until May, LG was nice enough to send one over for us to evaluate.

Take note of the SecurDisc logo on the drive's tray. According to Nero, only SecurDisc certified hardware will carry this logo. While LG's new drives are currently the only ones to be certified, Nero plans to build a logo certification program so that other software and hardware vendors can take advantage of the technology.

Burning With SecurDisc

________________________________________

Right now, the only software capable of burning a SecurDisc CD or DVD is Nero 7. While the retail version of the software will eventually support the technology, Nero has not released an update to enable this feature yet. Thankfully, LG sent along a customized version of the Nero 7 Essentials suite with SecurDisc already enabled in it.

When you launch Nero Express Essentials you can see that there are two new options on the "Data" menu. If you're writing to CD-R or CD-RW disc, you'll obviously want to create a SecureDisc Data CD. Likewise, you'll want to create a SecureDisc Data DVD when using DVD±R, DVD±RW, DVD±R DL and DVD-RAM media.

To add files to your compilation, simply click on the "Add" button or drag and drop them into Nero Express from Windows Explorer or My Computer. If you look closely, you can see that there are some settings for SecurDisc. By enabling these features, you can password protect the data and digitally sign the disc.

To digitally sign the disc, you will need a private key. If you haven't used this feature before, you will first need to create one. With Nero, this a fairly straightforward process. Simply move your mouse and type on the keyboard until enough random data is generated.

The private key is what you will use to digitally sign your discs. You will want to keep this in a safe and secure location. If you want others to be able to verify the contents of the disc, you will need to send them the public key.

If you choose to password protect your data, you'll need to provide a password. Nero will tell you how strong the password is depending on its length, complexity and the characters used.

While a strong password is desired, make sure it is something you can remember. If you forget your password, you will not be able to access any of the SecurDisc protected files or folders on the disc.

Once you've provided the necessary information, Nero will burn the data to disc. As I mentioned earlier, SecurDisc will fill the empty space with redundancy and checksum data. This can cause the burn process to take longer than it normally would.

When the burn process is complete, Nero will report what SecurDisc features the disc is using. One item of interest is the data reliability level. The higher the number, the greater the chance that you'll be able to recover your data if the disc becomes damaged.

Reading and Conclusion

________________________________________

While special hardware is required to write a SecurDisc CD or DVD, nearly any drive can be used to read them back. Files that are not password protected can be read without any special software. However, if you want to verify the authenticity of the disc's contents or access password protected files, you will need to install a compatible version of InCD or InCD Reader.

If you insert a disc protected by SecurDisc into a drive without having InCD installed, a message will come up in your default browser, directing you to Nero's SecurDisc website. At this time, a SecurDisc compatible version of InCD Reader is not available for download.

When installed, the SecurDisc compatible version of InCD adds an extra icon to the system tray. From here you can check a drive's supported features, enter a password for protected data, confirm the digital signature or check for altered data.

When a disc is inserted into a drive, InCD checks to see if it contains any password protected files. If if does, it will automatically prompt you for a password. Once the correct password is entered, you will have full access to the files on the disc.

One thing I should point out is that the files on the disc are always viewable, even if they are password protected. While you cannot view the contents without entering the correct password, the file names, sizes and dates are clearly visible. Personally, I'd like to see a way to hide them, at least until a password has been entered.

InCD can also be used to confirm a disc's digital signature. To do so, you will need the public key that corresponds to the private key used to sign the disc. If the disc passes the test you can be sure that the data has not been tampered with.

SecurDisc compatible versions of InCD also feature a built in integrity checker. By comparing the files to checksums stored on the disc, you can test the integrity of your data. If your data has become altered due to things like physical decay, InCD will notify you that your data should be backed up to another disc.

As I mentioned earlier, Nero is already expanding SecurDisc's capabilities to include support for copy protected PDF's. At this time, this is the only feature that requires a SecurDisc drive and special software for the files to be read back.

Conclusion:

While LG and Nero aren't the first companies to try to protect data stored on optical media, their SecurDisc technology is one of the better solutions we've seen. What makes SecurDisc stand out is that while it prevents unauthorized access to data, it also provides ways to protect it against physical damage. The technology is also flexible enough to let you combine its various features and mix both protected and unprotected data on the same disc. Best of all, SecurDisc supports all major CD and DVD formats and, in most cases, discs recorded with the technology can be read by any drive.

As much as I like SecurDisc, there are a few things I wish LG and Nero would have done differently. In particular, I'd like it if there was a way to hide password protected files until the correct password has been entered. In some ways, the name of the file can provide nearly as much information as the contents themselves. Not to mention, it gives data thieves an idea of what they have in their hands, even though they probably won't be able to break SecurDisc's encryption to get at it.

While I have not seen any concrete shipping dates yet, the word on the street is that we should see LG's first SecurDisc ready drives in May. Nero is also planning to include support for SecurDisc in the next Nero 7 update which should be available any day now.

LG's world first DVD re-writer with SecurDisc technology

Burning CDs and DVDs just got more secure

by Amy-Mae Elliott

________________________________________

29 May 2007 11:21 GMT - LG Electronics today launches its Super Multi Security drive in the UK, the world's first DVD/CD re-writer equipped with SecurDisc technology.

Exclusively licensed from Nero and HL Data Storage (until the September this year) SecurDisc enables users to add layers of security while a disc is being burned by applying passwords, digital signatures and copy protection to data DVD/CDs during the burning process.

Passwords of a minimum of sixteen characters in length can be burnt into the disc to prevent unauthorised access. Every disc is encrypted with a unique identity to assure the recipient of the authenticity and integrity of the disc and discs enabled with this function are protected from duplication, making the data accessible only through a viewing application.

In addition, data being burned is duplicated in the spare space on a disc to increase the possibility of restoring the data if the disc is damaged and discs are automatically checked to see if written data has been altered through decay or damage, allowing users to back up vital information before it becomes unreadable.

"Most companies keep sensitive personal and business information in their files and on their computers, information such as names, financial details and intellectual property, but if this data falls into the wrong hands, it can lead to fraud or identity theft", said Suan Choi, product manager for LG Electronics.

"We believe that safeguarding sensitive data is plain good business sense and with the Super Multi Security, our customers are given that extra layer of protection and confidence that their information is authentic and secure."

The Super Multi Blue drive is compatible with Blu-ray Disc, DVD, CD read/write and HD-DVD-ROM (read), offering consumers the most universal unit available.

The GGW-H10N can record up to 50GB of data, equivalent to 4-1/2 hours of high-definition video or 22 hours or standard definition video (on a dual layer 50GB BD-R/BD-RE recordable media). Surpassing the market standard, LG is providing a 4x recording speed of Blu-ray Discs, which means that it takes only 23-24 minutes to burn a full single layer BD-R disc (25GB), compared with 46-47 minutes for conventional 2x recording.

The product will be released during the first quarter of 2007, priced under US $1,200. The core technologies of Super Multi Blue Drive are Optical Pickup technology, which supports Blu-ray disc write/playback, HD DVD playback and DVD/CD write/playback, as well as the system controlling the Optical Pickup securely and effectively. All of these are LGs proprietary technologies. The LG-developed Optical Pickup is the worlds first device supporting both Blu-ray disc write/playback, HD DVD playback, which proves the companys unsurpassed technology in the optical storage field.

Super Multi Blue, also available from LG in the first dual-format high-definition disc player (model BH-100) available in early 2007, is expected to end customers confusion caused by the format war between Blu-ray disc and HD DVD, and promote the growth of next-generation DVD market.
