Which of the following acts is particularly focused on internet safety for children under 13?

The Children's Online Privacy Protection Act (COPPA) is specifically designed to protect the privacy of children under the age of 13 in the digital space. Enacted in 1998, this U.S. law requires that websites and online services directed toward children must obtain verifiable parental consent before collecting personal information from children. It aims to ensure that parents have control over what information is collected from their children and how it is used.

By establishing guidelines for the collection, use, and disclosure of personal information from children, COPPA emphasizes the importance of internet safety for minors, focusing on their right to privacy in an age where digital exposure is commonplace. This act addresses concerns related to children's vulnerability online, making it a critical piece of legislation regarding child safety on the internet.

The other options address different aspects of technology and data privacy but do not specifically target internet safety for children under 13. For instance, Common Criteria deals with security assurance for IT products, the Computer Fraud and Abuse Act focuses on crimes involving computers, and the Personal Information Protection and Electronic Documents Act is Canadian legislation aimed at protecting personal information in the private sector.
