Following the impressive development of networks, information technologies have entered the age of large volumes of data. The development of technology has created more and more databases and has allowed individuals to access it easily. Databases are essential tools in an economy founded on knowledge. The protection of investment in making databases is not harmonized internationally. Electronic networks such as the Internet, which represent a fantastic instrument of communication and sharing tool at the worldwide scale, sometimes lead to a violation of fundamental rights such as the right to privacy. Laws that protect personal data and privacy are still present almost everywhere in the world. However, in Vietnam, no specific law exists on the protection of personal information. The same lack appears for the protection of databases. Furthermore, although the world has been interested in Cloud Computing and Big Data for several years, Vietnam only began dealing with these subjects in 2008 for Cloud, and 2013 for Big Data. Due to its membership in the Trans-Pacific Partnership, laws to protect databases and personal data and the legal status of Cloud and Big Data, Vietnam will surely have to drastically change its legal system.
