What is defined as publicly available information obtained lawfully?

The term that encompasses publicly available information obtained lawfully is "open-source information." This type of information can include data derived from publicly accessible documents, reports, academic publications, and online platforms that are easily available to anyone. The distinction of being lawful is key; it emphasizes that the information must be obtained without violating any legal or ethical guidelines.

In contrast, terms like "free-source information" could imply access issues or might refer to materials that are free but not necessarily open and lawful. "Confidential-source information" pertains to data that is not meant for public access, often protected due to privacy or proprietary concerns, thus contradicting the idea of being publicly available. "Wide-source information" does not have a recognized meaning in this context and does not align with the concept of lawful, publicly available data. Therefore, open-source information is the most accurate and relevant terminology in this situation.
