[Reference: https://www.isaca.org/resources/isaca-journal/issues/2016/volume-6/an-ethical-approach-to-data-privacy-protection, Consent is a privacy principle that requires obtaining the permission or agreement of the data subjects before collecting, using, disclosing or transferring their personal data for specific purposes. Consent can be explicit or implicit, depending on the context and nature of the data processing activity and the applicable laws and regulations. An email opt-in form on a website is an example of obtaining explicit consent from the data subjects who voluntarily provide their email address and agree to receive marketing communications from the website owner or operator. The other options are not relevant to an email opt-in form on a website. Accuracy is a privacy principle that requires ensuring that the personal data is correct, complete and up-to-date. Transparency is a privacy principle that requires informing the data subjects about the identity and contact details of the data controller, the purposes and legal bases of the data processing, the rights and choices of the data subjects, and the safeguards and measures to protect the data. Integrity is a privacy principle that requires protecting the personal data from unauthorized or accidental modification, deletion or corruption. , p. 97-98 References: : CDPSE Review Manual (Digital Version), ]
