What is DRM and How's it works?

DRM, or digital rights management, is a technology used to control access to digital content. It is typically used by companies to prevent unauthorized access to or copying of their content.

DRM technology works by encrypting the digital content and requiring users to obtain a license or key in order to access the content. This license is typically tied to a specific device, so the content can only be accessed on that device. When the user attempts to access the content, the DRM technology checks the license and only allows access if the license is valid.

Some common types of DRM include:

• Encryption: This is the most basic form of DRM, in which the content is encrypted using a secret key. To access the content, the user must enter the correct key or password.
• Trusted computing: This type of DRM uses a hardware-based security system to control access to the content. The content is encrypted and can only be decrypted on a device with a trusted hardware component, such as a Trusted Platform Module (TPM).
• Watermarking: This is a technique in which a unique identifier, such as a user's name or device ID, is embedded in the content. This allows the content to be traced back to the user if it is shared without permission.

Overall, DRM technology is designed to protect digital content from unauthorized access and copying, but it can
