CDs and DVDs serve as storage for various types of data, be it pictures, music, videos, or documents. Once the data is burned on the disc, it can easily be accessed through a CD or DVD player on your computer or portable media device. The data can also be copied over and over again to a hard drive, portable media device or another CD or DVD. If you have sensitive documents or files you may wish to keep to yourself or limit it from being copied, there are several ways to accomplish this.
- Create a Zip file and use password protection. You can protect your files from being accessed by anyone through the WinZip or WinRar program. Identify the files to be placed on the CD or DVD then launch the WinZip or Winrar program. From the program you can browse for the files and compress them, choose the best compression size you want. Another way is to right-click the file on your hard disk then select Send To, then Click Compressed (zipped) Folder. A compressed folder will be created on your desktop, and then you can add more files to the folder using the copy and paste method. Encrypt your compressed files with a password to protect the data. In the WinZip program select your compressed folder then go to the menu and select File. Under the File options click set default password, this will open a dialogue box. Type in the password you prefer then confirm by typing again on the box below. Once you’re done click ok and exit the program. The file is now encrypted with a password that you can share with select people.
- Download or purchase CD and DVD protection software. There are dozens of CD and DVD copy protection software for purchase or download. Some of the programs can encrypt all your files and protect it from being accessed or copied; they will even have their own viewer or player, so your files can only be accessed through that particular viewer or player. Others will work the same way but will have a small decryption program to be installed on your pc so it will automatically reveal your files once it is accessed. It cannot be accessed on any other system other than yours.
- Make use of Digital Rights Management technology. Most audio distribution companies use this technology on their audio products. It controls and limits how the product is used by the individuals who purchase them. The Digital Rights Management technology lets you access the original contents of the CD and allows you to backup the data for your personal use, but it won’t allow you to copy from the backed up data.
Although the DRM technology may be a good way to protect the data on CDs or DVDs, many believe it impedes on their rights as consumers.
