What process is Aaron tasked with implementing in the albums distributed by his record label?

The correct answer is watermarking. Watermarking is a process that involves embedding information into digital media, such as audio files, without degrading the quality of the original content. This technique is particularly useful in the music industry for protecting intellectual property, as it allows record labels to assert ownership over their distributed albums and deter unauthorized duplication or distribution.

Watermarks can serve various purposes, including identifying the owner of the content or providing information about usage rights. This embedded information is typically difficult to remove without significantly altering the original media, making watermarking an effective method for tracking and protecting creative works in a digital format.

In contrast, options such as encryption and digital signatures serve different functions. Encryption is primarily aimed at securing data by making it inaccessible without the right decryption key, while digital signatures verify the authenticity and integrity of the content but don't provide a means for tracking usage or ownership in the same way watermarking does. Access control, on the other hand, pertains to limiting who can view or interact with the media rather than embedding information within the digital files themselves. Each of these processes serves essential roles in data security but does not specifically address the need to assert ownership and protect intellectual property in the same manner that watermarking does.
