The rapid development of technical technologies used by offline and online retailers has made consumers' concerns regarding privacy increasingly heightened. With that comes countless tensions for retailers and consumers, trade-offs and compromises just to personalize the shopping experience. In this article, we study privacy regulations when businesses use artificial intelligence in retail systems in the United States - a leading country in artificial intelligence, the European Union - the European Union. The region has the strictest privacy legal policies and Vietnam - a developing country with great potential in artificial intelligence. Based on the mentioned legal regulations, we provide an overview of the data privacy risks that artificial intelligence can bring in the retail industry and the reasonable ways in which Governments of developing countries should react so as not to unintentionally inhibit the development of the digital economy by their strict legal policies. Along with that, our research direction also lays a promising foundation for academic research on privacy rights and a model for building privacy protection laws that take into account the balance between the law and the law. and economic development orientation.
