Under the California Consumer Privacy Act (CCPA), a business that collects personal information of California residents must notify them of a data breach if their personal information is subject to unauthorized access and exfiltration, theft, or disclosure as a result of the business's violation of the duty to implement and maintain reasonable security procedures and practices. However, the CCPA excludes encrypted or redacted personal information from the definition of personal information, unless the encryption key or security credential is also compromised. Therefore, Privacy Is Hiring Inc. would need to notify the affected individuals only if the encryption keys were also taken along with the credit card information, as this would render the encryption ineffective and expose

the personal information to unauthorized access. The other options are not relevant to the CCPA notification requirement, although they may be relevant to other laws or best practices.Reference:CCPA(Section 1798.150),IAPP CIPP/US Study Guide(p. 63-64)
