What constitutes 'unauthorized use' of City Data?

Data mining for commercial purposes is considered unauthorized use of City Data because it typically involves leveraging sensitive or proprietary information for economic gain without the proper authorization or agreement from the city. This practice may violate terms of use outlined in data-sharing agreements and can potentially compromise the integrity, confidentiality, and security of the data.

City Data is often intended for public service initiatives, research, or improving municipal operations, rather than for exploiting the data for commercial gain. As such, utilizing this information for profit-making activities is generally prohibited to ensure that the data is used ethically and responsibly.

In contrast, the other scenarios do not align with the characteristics of unauthorized use: using data for service delivery aligns with the intended purpose of City Data, while data processing for security analysis is generally viewed as a legitimate operation to protect public interests. Data mining for personal benefits might raise ethical concerns, but it does not inherently carry the same level of violation of policy as commercial exploitation does.
