Question: What is the primary purpose of assigning a unique Lawful Interception Identifier (LIID) for each target identity or a group of target identities related to the same target in the context of lawful interception?
Option 1: To facilitate direct billing of intercepted communications to the Law Enforcement Agency (LEA).
Option 2: To enable the interception of all communications within a specific geographic area.
Option 3: To maintain confidentiality and limit knowledge about a specific target within authorized parties, while facilitating identification and correlation across handover interfaces.
Option 4: To automate the process of obtaining lawful authorization for interceptions.
Explanation: The correct answer highlights the key benefit of using LIIDs: maintaining confidentiality by limiting knowledge about a target while ensuring effective identification and correlation across interfaces between authorized operators and LEAs, aligning with minimizing access to sensitive information.
