What exactly is meant by the phrase "digital rights management"?
By utilising digital rights management, owners of content copyrights have the ability to monitor how and by whom their content is used, as well as place restrictions on the methods in which the work is duplicated or spread (DRM).
The term "digital rights management," or "DRM," refers to a system that protects the copyrights of electronic media and makes certain that content creators are paid properly for their efforts.
Over-the-top (OTT) services include Netflix, Hulu, and Amazon Prime. Video digital rights management (DRM) industry leaders including Microsoft's PlayReady, Google's Widevine, and Apple's FairPlay employ it.
The digital rights management (DRM) technology can be useful for many different types of high-tech devices, including personal computers, mobile phones, smart televisions, gaming consoles, ebook readers, and many more.
Netflix protects its high-quality digital content from being pirated and restricts access to it in a number of different ways. Two examples of these methods are the PlayReady digital rights management system from Microsoft and Video watermarking.
Packaging for content that is secured by digital rights management (DRM).
Media content can be encrypted and protected against unauthorised use through the use of a technology called digital rights management (DRM).
It is feasible to package content protected by digital rights management (DRM) in formats such as real-time HTTP streaming or Dynamic Adaptive Streaming over HTTP (DASH), which can then be used to safeguard the content that was originally created (HLS).
Due to the fact that the Moving Picture Experts Group was the organisation that initially developed the DASH format, it is often referred as as MPEG-DASH (MPEG).
When it comes to encrypting digital content in various formats, the use of the Advanced Encryption Standard, or AES, has become the industry standard.
The data that will eventually be viewed by the end user is decrypted and sent to the device that will display it to the user.
A customer is required to possess both a Digital Rights Management (DRM) licence and the encryption key that was granted by a DRM licence server in order to view the material. The management of this procedure is taken care of by a multi-DRM service.
AES-128 is the name of the standard that refers to the encryption algorithm's 128-bit length.
Because of the superior level of protection that they offer, encryption standards such as this one are highly recommended by the National Security Agency (NSA).
AES-128 is used for the encryption of video files by HLS, Adobe's Real Time Messaging Protocol (RTMP), and content that is secured by DRM.
According to the opinions of those knowledgeable in the relevant industry, files encrypted with AES-128 cannot be decoded unless the appropriate decryption key is available.
The Advanced Encryption Standard (AES) is a symmetric key algorithm, which means that it encrypts and decrypts data utilising the same private key.
Blocks are the fundamental unit of encoding for video files when using the HLS technique.
The ciphertext from the previous block is utilised in the encryption process for the next block.
In order to maintain its confidentiality, the chain cypher decryption procedure is used to the decryption of the video file on a block-by-block basis.
It is possible for an unprotected decryption key to leak out of the AES algorithm, which is a strong method for encrypting a video file. However, it does this by allowing an unprotected decryption key to fall into the hands of an unauthorised user. This makes it possible for an unprotected decryption key to leak out of the AES algorithm.
OTT service providers are aware of this issue, which is why they employ a multi-DRM service to safeguard their content and guarantee that their customers receive their licence keys in a safe and secure manner.
Because of this, the over-the-top (OTT) business needs a reliable multi-DRM software as a service that is capable of managing DRM licences issued by worldwide leaders such as Widevine.
Conclusion
It is utilised by major players in the video DRM business such as Microsoft's PlayReady, Google's Widevine, and Apple's FairPlay. It is used on over-the-top (OTT) platforms such as Netflix, Hulu, and Amazon Prime. When it comes to encrypting digital content in various formats, the use of the Advanced Encryption Standard, or AES, has become the industry standard.
