What is digital rights management?
The growth of digital media and modern technology has significantly increased organizations’ and individuals’ worries about copyright ownership. With a few mouse clicks, countless copyrighted photos, films, and music files are downloaded or shared without prior authorization. Furthermore, current techniques and technologies have made it simple to convert media (mainly copyrighted) into numerous digital formats for convenient transport and distribution. This is known as ripping, and the best approach is to use DRM technology. This, along with the internet and hundreds of file-sharing applications (such as Torrents), greatly facilitates the illicit large-scale dissemination of copyright media copies (digital piracy).
Digital Rights Management (DRM) is the technique of securing digital information, such as video, to prevent illegal use and piracy of copyrighted material. Accessing the material necessitates user authentication as well as the specified time duration.
History of Digital Rights Management (DRM)
Piracy existed prior to the development of the internet in the 1990s, although it was less common. However, when digital music and internet films grew more popular, nations scrambled to implement regulations to combat digital piracy. New regulations were enacted, and new business models were tested, such that by the 2010s, digital rights management was a priority rather than an afterthought.
Not only did governments intervene, but technology firms began developing technologies to help content creators track and prevent digital theft. Since 1983, when the first example of DRM software was created to allow payments to be transferred to the copyright holder, new technologies have been produced on a regular basis, including software to impose copy limits, runtime restrictions, regional lockouts, and tracking.
Why Is DRM Important?
While stealing or duplicating information is an age-old practice, modern technology has made copying much easier. Many copyrighted photographs, films, and music recordings may be shared or downloaded on the internet with a few mouse clicks, frequently without the owner’s permission. According to research conducted by the United States Chamber of Commerce’s Global Innovation Policy Center, internet piracy costs the US economy at least $29.2 billion in lost income each year.
Digital Rights Management is crucial for organisations because it allows them to regulate access to copyrighted digital materials. The extent of control includes monitoring how the public utilises its material, tracking who has viewed it, and combating piracy and unauthorised usage.
DRM Is Vital to Data Security
Digital Rights Management can help businesses limit access to important documents. DRM’s restrictive technologies also serve to secure a company’s proprietary information. DRM assists organisations, particularly those in the healthcare or financial sectors, in maintaining regulatory compliance, particularly with relation to privacy rules for personally identifiable information.
When Digital Rights Management systems are used, auditors and other investigators are better able to track down data leaks.
Provides Protection from Legal Liability
A primary goal of Digital Rights Management is to provide copyright owners control over what their consumers may do with their works. As a result, DRM offers broad protection by encompassing a wide range of digital items, including e-books, music, video, software, and many types of private information.
Copyright holders have a compelling obligation to preserve their intellectual property since unauthorised usage has legal consequences for them. As a result, DRM aims to prevent unauthorised copying of these materials. So, Digital Rights Management is critical for providing owners control over their work and prevents it from being used, updated, or altered in ways that were not intended.
Licensing Provisions and Agreements
Digital Rights Management technology helps content providers to preserve ownership of their work while also exerting greater control over their goods. Licensing contracts and agreements legally define what users may and cannot do with their creations.
Ensures Compensation from Intellectual Property (IP)
The most obvious purpose for Digital Rights Management is to safeguard copyright owners’ financial interests. This enables them to realise the benefits of their labour and investment in innovation. One of the most important ways Digital Rights Management does this is by guaranteeing that digital material or files are not transferred or stolen without proper pay to its authors, producers, and publishers.
How does Digital Rights Management (DRM) work?
Although digital content is protected by copyright rules, policing the internet to detect unlawful behavior is difficult. So DRM takes a proactive approach to securing digital content by preventing theft in the first place.
There are several techniques to DRM, with ongoing efforts to develop new solutions. Many Digital Rights Management technologies utilize encryption, or computer code placed in digital files, to restrict access or usage.
- Control how many times, devices, individuals, or time periods the content can be accessed or installed.
- Establish ownership and monitor content usage.
- Set expiration dates or viewing limits on material.
- Prevent viewers from taking screenshots, modifying, printing, sharing, or saving your materials.
- Restrict access by IP addresses, locations, or devices.
Copy Protection
These tactics limit access by prohibiting users from creating copies of a material. They are often implemented via encryption, which encodes digital content in a code that can only be read by devices or applications that have the necessary key to open it. This method is sometimes referred to as scrambling. Other forms of copy protection include digital watermarks, fingerprinting, and restricted copying characteristics, such as rootkit software.
Permission management
This type of restriction restricts who has permission to utilize a certain work. Software licenses and keys, user authentication and IP authentication protocols, proxy servers, virtual private networks (VPNs), regional limitation or geo-blocking, and engineering things to work exclusively with specific hardware or software are all examples of Digital Rights Management tactics.
Many digital content makers use numerous DRM tactics to limit or control the usage of their work.
The Technology Behind DRM
With a mixture of encryption, licensing system and access control, Digital Rights Management (DRM) technology serves to protect the digital content form unauthorized use and piracy. At its core, DRM encodes digital media files (e.g. videos, music, eBooks or software) so that they are inaccessible without having an inValid decryption key. These are typically tied to a user’s specific license, which will define how the content can be used, for example, only on certain devices, or not shared at all.
As an example, streaming services like Netflix, Disney+, and Spotify relies on a proprietary Digital Rights Management systems like Google Widevine, Microsoft PlayReady, and Apple FairPlay which protection the content that can only be used by authenticated users. These systems also dynamically repurposes for various platforms and devices and yet provides security throughout. The advanced features such as digital watermarking provide protection to the content owners by tracking the unauthorized copies.
The current trends in Digital Rights Management take full advantage of it’s scalability, user experience, and futurizing against piracy. One example is that newer codecs such as AV1 and HEVC are already able to be integrated into DRM frameworks to enable high definition streaming with lower bit rates. On top of that, cloud based DRM solutions have progressed, more specifically, taking advantage of secure cloud environments to make digital license distribution and management as efficient as possible, especially for large scale content delivery networks (CDNs).
On the other hand, blockchain is making a name of itself as a promising technology in Digital Rights Management as well, providing the decentralized means of handling digital rights and licenses in a secure and transparent way. These innovations are exactly what is needed to deal with the challenges of an increasingly global and integrated digital ecosystem between content protection and legitimate access for users.
DRM Technologies
There are different types of Digital Rights Management technologies designed to protect various digital content:
- Encryption-based DRM: Encrypts the content, making it unreadable without a decryption key.
- Watermarking-based DRM: Embeds a unique identifier into the content, allowing tracking of its distribution.
- License-based DRM: Requires users to obtain a license or key to access the content, which can expire or be revoked.
- Cloud-based DRM: Stores content in the cloud and controls access through a cloud service.
These Digital Rights Management systems are used in industries such as media, publishing, software, and gaming to safeguard intellectual property while also generating income.
Digital Rights Management (DRM) Types
Platform Based DRM
DRM systems can be specific to different platforms and devices. The reason for this is that other platforms and devices have their own unique software and hardware capabilities, security mechanisms, and content distribution channels. As a result, DRM systems need to be tailored and implemented accordingly to ensure compatibility and effectiveness.
A typical DRM Content Protection consists of multi DRM, these different DRMs caters to different devices and browsers. The major ones are:
Google Widevine: Developed by Widevine Technologies, bought by Google. Google’s content protection system for premium media. Widevine is used by major content services around the world, including Google Play, YouTube, Netflix, Hulu, Amazon, and more. Widevine is embedded in web browsers such as Chrome and Firefox, and devices with Android OS and other various OTT devices.
Apple Fairplay: Apple’s FairPlay Streaming (FPS) DRM can safely distribute streaming video to client devices via the HTTP live streaming protocol. FPS technology enables content producers, encoding suppliers, and content delivery networks (CDNs) to encrypt material, securely share content, and safeguard playback on iOS, tvOS, watchOS, and the Safari browser on macOS and iOS. Services wise Apple TV, iTunes uses Apple Fairplay.
Microsoft Playready: Microsoft PlayReady content access and protection technology is a suite of technologies that may be used to transport audio/video material more securely over a network while also preventing unauthorised use. Tight integration with Microsoft platforms including Windows 8+, Xbox, Windows Phone, Mediaroom, and Microsoft Silverlight for Windows and Mac.
But some DRM can also be used on multi-platform, such as:
Marlin: Developed by the Marlin Developer Community, which is a consortium of various companies including Intertrust, Panasonic, Philips, Samsung, and Sony. It is designed to be platform-agnostic and interoperable across different devices and platforms. It supports a wide range of operating systems, including mobile, desktop, and embedded systems.
ClearKey: Developed by the World Wide Web Consortium (W3C) as part of the Encrypted Media Extensions (EME) specification for web browsers and provides a basic level of content protection.
Device-Based DRM
This sort of DRM binds the material to certain hardware or devices, guaranteeing that it can only be accessed through approved devices.
Sony DRM for PlayStation: Ensures games can only be played on PlayStation consoles.
Nintendo DRM: Used to restrict games to specific consoles or user accounts.
Xbox DRM: Similar to PlayStation DRM, tied to Xbox consoles.
Watermarking DRM
Watermarking is a DRM technique that embeds visible or invisible identifiers into information to track its origins in the event of illicit distribution.

DRM allows content providers to develop revenue streams by controlling access and distribution. Creators can monetise their material through subscription models, pay-per-view, or timed access. DRM also provides for variable price choices, allowing producers to target different audience segments while maximizing revenue.
Securing Copyrighted Works
DRM protects copyrighted goods of authors and publishers by encrypting digital content and restricting access to it. This inhibits illicit copying, sharing, and dissemination, allowing authors to retain ownership and control of their work.
Copyright Law Compliance
DRM enables content makers and distributors to comply with copyright laws and regulations. Implementing DRM allows them to safeguard their digital material from piracy and illegal usage, avoiding legal complications and significant fines.
Enhancing the User Experience
DRM can both safeguard digital material and improve the user experience. Creators may increase user engagement and happiness by offering a secure access point to information. DRM can also allow features like as offline access, multi-device support, and tailored content suggestions, which improves the user experience.
Flexible Pricing Options
Allows for subscription models, pay-per-view, timed access, and flexible pricing
Drawbacks and Challenges of DRM
While DRM has advantages, it also has significant drawbacks that might affect the user experience, compatibility, and create privacy issues.
User Access Restrictions
One disadvantage of DRM is that it restricts how people access and utilize digital content that they have purchased. By restricting access, DRM may hinder users from exercising their fair use rights. For example, a user who purchases a digital movie may be unable to watch it on specific devices or share it with family members. These limits might irritate consumers who believe their rights are being unfairly constrained.
Device and Platform Compatibility Issues
DRM software may not operate on all devices and systems. This lack of interoperability can be quite frustrating for consumers who expect to be able to access their paid material effortlessly across many devices. For example, a movie purchased on one platform may not play on another owing to differences in DRM technologies, resulting in an uncomfortable user experience.
Privacy Concerns
DRM can cause privacy problems since it involves monitoring and tracking user activity. This raises concerns regarding data privacy and the potential abuse of user information. Furthermore, DRM systems may be prone to hacking or workarounds, exposing users to security hazards.
Implementation and Maintenance Costs
Implementing and maintaining DRM systems may be costly and time-consuming. Content makers and distributors need to spend in DRM technology, infrastructure, and staff to manage and upgrade their DRM systems. These fees might be excessively high, particularly for smaller content providers and independent publishers.
Performance Impact
DRM can degrade system performance, resulting in delayed loading times or failures. This might result in a difficult user experience, particularly for individuals with slower internet connections or older devices.
The Future of Digital Rights Management
Emerging Technologies and DRM
Blockchain is a potential technology for digital rights management. It maintains clear and tamper-proof records of content distribution and use. Smart contracts may automatically enforce license conditions, lowering costs and increasing security. Additionally, artificial intelligence (AI) and machine learning will improve the security and effectiveness of DRM solutions.
Balancing Protection with User Experience
Content makers and distributors must discover strategies to safeguard intellectual property while maintaining user experience. This necessitates the use of technologies that efficiently protect material while enabling fair usage and assuring cross-device and platform interoperability. By finding the correct balance, DRM technologies can protect intellectual property rights while also fostering productivity and creativity.
DRM systems will need to adapt to future patterns in digital content access, such as streaming services and mobile device usage. Businesses that embrace DRM advances may safeguard the integrity and accessibility of digital information, protect intellectual property, and foster a secure and collaborative environment.
We conclude that Digital Rights Management (DRM) is valuable in protecting intellectual property in a host of industries, including gaming and streaming platforms, eBooks, and enterprise security. Content protection by different types of DRM such as content protection, device based restriction, and license based access is used by creators and organization to maintain their content free to pirate and unauthorized use.
However, DRM’s inherently fine balance between security and user convenience often determines its effectiveness as well as its acceptance. DRM solutions are having to evolve with the technology, while building an open standard and responding to the user concerns will be key to building the trust to ensure large scale adoption. At the end of the day, DRM is a vital property protection tool in a world ever more connected.
