The effective date of privacy rules varies depending on the specific regulation under discussion. The Children's Online Privacy Protection Rule was updated in 2013, the GDPR took effect in 2018, and changes to Ozone standards in the US became effective on December 28, 2015.
Step-by-step explanation:
The privacy rule that the student is likely referring to would depend on the specific context, as several privacy-related rules and regulations have been enacted over time. If the student is asking about the Children's Online Privacy Protection Rule, according to the information provided, it was enacted in 1998 and has seen various updates, the latest one being in 2013.
The European Union has also enacted extensive data protection laws, like the General Data Protection Regulation (GDPR), which took effect on May 25, 2018, and applies to all member countries. In the United States, specific privacy rules with a broader scope such as changes to Ozone standards were implemented, with the final rule signed on October 1, 2015, and effective December 28, 2015.
Discussing the privacy rule within the context of privacy and surveillance, the USA PATRIOT Act's Section 215 and the operations of the Foreign Intelligence Surveillance Court are also significant points of reference.
