What is DRM?
Digital Rights Management (DRM) The company’s attempt to combat piracy by carefully controlling how and when media is used. There are, roughly, 10,742,489 types of DRM and copy protection, with nearly every company having their own role.
The company claims that DRM is essential to combating copyright infringement online and keeping consumers safe from viruses. But there is no evidence that DRM helps against either. On the other hand, DRM helps large companies contain innovation and competition by making it easier to stop “unauthorized” use of media and technology.
DRM has grown rapidly thanks to the DMCA of 1998 (DMCA), which seeks to block any attempt to bypass DRM.
Why do we use DRM?
Software and digital media companies spend most of their money and time on researching, developing, and marketing their products. However, in this age of technology and communication, it is not difficult for people with ill-gotten interests to produce and distribute pirated / pirated copies of applications, which can be used without paying.
Piracy leads to huge revenue losses. There are many copyright protection laws (which vary from state to state) that prohibit such works, but even they fail to prevent piracy.
This is where DRM comes in. The various technologies that fall into this category put in place mechanisms that make it very difficult, if not impossible, to steal a product. Unauthorized copying, distribution and use of the product is prohibited, due to the access controls it imposes.
How does DRM work?
Since the dawn of the digital age, copyright holders have been working to tackle the problem of piracy. It was originally software-based, in an effort to prevent people from copying computer games and operating systems. As music, movies, TV and sports move into the digital world, rights holders need to find lightweight, unobtrusive and effective DRM technology solutions to protect their intellectual property.
Many DRM tools work through encryption, or computer code embedded in digital content, to restrict access or use. This tool can control how often, devices, people, or time period content can be accessed or installed. Here is an overview of how DRM technology works:
- Digital content is encrypted (also known as “packets”) and can only be opened with a secret encryption key
- This key is attached to a digital license that contains rules regarding the use of the content
- When a user requests to view content (for example, clicking on a show to watch), the DRM client verifies the license
- If satisfied, the user receives a validation code
- This token tells the encryption key that it is acceptable to open the content
DRM Use Case
DRM technology appears in a wide variety of digital materials, from videos, music, and e-books to business information, database subscriptions, and software. The creators of these works are concerned with DRM not only to prevent unauthorized copying, but also to prevent people from changing their work or using it in ways they don’t want to. Here are some examples of DRM use cases
The Apple iTunes Music Store uses digital rights management (DRM) to limit the number of devices songs can be played on. Audio files downloaded from iTunes Music Store include data about purchases and usage activity, and songs will not be played on unauthorized devices. Apple iBooks are protected by Apple’s FairPlay technology, which requires iBooks to be read on Apple devices.
Microsoft users must agree to a user license and key entry before installing Windows or Office software. Furthermore, their DRM technology called PlayReady is used to make the distribution of audio/video content over the network more secure, to help prevent unauthorized use.
A variety of companies use digital rights management technology to protect sensitive documents, from contracts and strategic plans to confidential employee data. DRM tools can control who can access files and how they are used. They can prevent files from being changed, saved, duplicated, printed, and tracked when viewed.
Individuals who purchase digital content can help prevent unauthorized, unwanted use by tracking and complying with associated license information. Non-royalty images, videos, or audio files often come with restrictions on how, when, and even where the content can be used.
So what is DRM? DRM stands for DRM It is a technology designed to protect copyright and prevent unauthorized modification or distribution. It is useful for manufacturers of applications and digital media to enforce access control over their products.
