This document summarizes key aspects of data privacy protection based on a journal article. It discusses how data privacy can be achieved through technical and social solutions, as well as complying with relevant laws and regulations. International Data Privacy Principles are proposed that draw from standards in Asia, Europe, the US and internationally. Hong Kong's Personal Data Privacy Ordinance is used as an example, outlining its six data protection principles. Protecting data privacy is seen as urgent and complex due to issues like socio-techno risks from technology use and the need to balance various parameters in contractual agreements regarding data use.
