DRM
Digital Rights Management (DRM) is a copyright protection mechanism that restricts the use of digital content through techniques such as encryption and license verification. It is widely applied across digital content platforms including game consoles, streaming services, and e-book distribution systems.

If Readwise wants to build a bookstore, it must either negotiate licensing with publishers one by one (which is costly) or sell only DRM-free independent publications (which means a limited catalog).
Under the licensing framework, DRM makes the "license" enforceable: platforms can remotely revoke activation, limit the number of concurrently online devices, or make already-downloaded content unusable after service termination.
DRM (digital rights management) refers to technical means used by vendors to control access to, copying of, and distribution of digital content, with common forms including online activation checks, encrypted executables, and hardware binding.
Digital games rely on server verification, DRM protection and continuous updates, so how to define genuine "ownership" technically is an enforcement challenge.
The modern DRM framework is jointly composed of the kernel-mode KMS (Kernel Mode Setting) and the user-mode libdrm library.
The amdgpu driver interacts with hardware through the DRM subsystem, device trees, and standardized bus interfaces.
Sony employs a hardware-bound encryption scheme in which game content is stored in encrypted form, and decryption keys are dynamically delivered via online verification with Sony's servers and stored in a secure enclave.
The Asahi team needed to implement an entirely new memory management backend within the DRM subsystem to accommodate the cache coherency protocol and address space layout unique to Apple hardware.
Technical heritage in the digital age faces unique preservation challenges, including software dependency on specific hardware and operating systems, the transience of data formats, proprietary file formats, DRM encryption, and cloud service dependency.
