Generally, content publishers distribute their content via CD or DVD disc media when it comes to their important content. For over 20 years, CD and DVD discs have been the main method of distributing copy-protected media such as audio and video content. However, CD/DVD based copy protection has been challenging the limitations of what types of content and necessities of a content publisher can be stored on the discs.
In this blog, we’ll discuss three cases where CD and DVD based copy protection solutions cannot function properly when distributing content.
We cannot use it when the content is important and very high in value.
Generally, audio and video content that is distributed via CD/DVD discs are cheap(under the value of fifty US dollars). In this case, content publishers can distribute a large number of CD/DVD containing content using the CD/DVD based copy protection. It is cost-effective for content publishers to distribute in this method, even if some of their content can be copied illegally with cheap or free technological resources available on the internet. There are a lot of CD cracking tools for the general public to use such as Clone CD, which allows even the non-tech savvy people to copy content. Since such resources exist, if you want to distribute content worth hundreds or thousands of dollars, you should not use CD/DVD copy protection solution.
Sharing confidential corporate information internally.
While it is efficient to share data digitally, when sharing confidential information within the company there is crucial and almost irreparable damage if it is exposed outside of the organization. For example, the service manual of a motor company would be shared with various cooperative auto service partners and dealers to enhance their quality of service. However, the exposure of this information to customers, competitors, or outside of the company, in general, may severely damage the reputation and reliability of the company. This service manual can be updated a lot regularly and can be used in the case of internet disconnection. The level of security should be kept high on this content even if there’s a high number of a distribution involved. In this case, CD/DVD based copy protection cannot be used.
Sometimes want to distribute content which cannot be viewed with an existing standard viewing program.
Existing CD/DVD copy protection solutions generally use standard playing or viewing programs to play normal audio and video formatted files. For example, an e-book generally uses a certain viewer such as a PDF viewer. The content of the e-book would be transferred into a PDF format from the publishers’ original format. In this process, there are some issues where the content cannot function efficiently.
1. If the Content has too many HTML or PDF links.
2. PPT file is multimedia, mixed with animation, sounds, and videos.
3. Content is in the form of a .EXE file.
4. Ultra high definition video file that is not compatible with the standard/existing player.
In addition to the three cases, there are some other challenges that come from the rapidly changing IT market environment. Recently, newly released laptops started to stop providing CD/DVD drives. The capacity of a DVD disc is at most 4.7 GB. It is inconvenient to keep track of multiple discs when high-resolution files are involved.
In conclusion, CD/DVD based copy protection solutions have relatively good quality and standards as well as cost-effectiveness, but it has met some challenges with the various growing needs of digital content publishers. Nowadays, Secudrive USB Copy Protection, one of USB based copy protection solutions are used to distribute large amounts of content while providing higher security functions than CD/DVD based copy protection solutions.
