Overview of the Data Protection Act in Thailand
This document is intended to provide a summary of the data protection legislation in Thailand, known as the Personal Data Protection Act (PDPA).
Background
Data privacy has become a critical issue for individuals and businesses around the world as the digital age has made it increasingly easy to collect, store, and process personal data. In response to growing concerns over data protection and privacy, several countries have implemented comprehensive data protection law.
In Thailand, the Personal Data Protection Act (PDPA)1was enacted in 2019 and has been fully enforceable since June 2022. 2
The Personal Data Protection Committee (PDPC) is the regulatory authority that is responsible for the regulation of personal data and enforcement of the PDPA.
Overview of the PDPA
The PDPA is Thailand's first comprehensive data protection legislation and is largely influenced by the European Union's General Data Protection Regulation (GDPR).
The PDPA's primary goal is to protect the personal data of individuals (referred to as “data subjects”) by regulating the collection, use, disclosure, and transfer (collectively, the “processing”) of personal data.
Further, “with the PDPA in place, Thai businesses can satisfy the EU’s strict requirements on data export measures under the Thailand-EU FTA,”3 thus expanding the reach of their businesses to the Europe and beyond.
Currently, the PDPA does not have an official English translation. Knowing this, Pragma has collaborated with official Thai translators and put together this guide for reference.
Definitions
There are a total of nine (9) definitions set out in the PDPA; these are listed in the table below.
Term | Definition |
---|---|
Personal data | “Any information relating to a Person that enables the identification of such Person, whether directly or indirectly, but not including the information of the deceased Persons in particular.”5 |
Data Controller | “A Person or a juristic person having the power and duties to make decisions regarding the collection, use, or disclosure of the Personal Data.”6 |
Data Processor | “A Person or a juristic person who operates in relation to the collection, use, or disclosure of the Personal Data pursuant to the orders given by or on behalf of a Data Controller, whereby such Person or juristic person is not the Data Controller.”7 |
Person | “A natural person.”8 |
Committee | “The Personal Data Protection Committee (PDPC).”9 |
Competent Official | “Any person appointed by the Minister to perform acts under this Act.”10 |
Office | “Office of the Personal Data Protection Committee.”11 |
Secretary-General | “Secretary-General of the Personal Data Protection Committee.”12 |
Minister | “The Minster who is in charge under this act.”13 |
Principles Relating to Use of Personal Data
There are several principles upon which the PDPA is based. These dictate that personal data must be:
- Accurate and up to date;
- Used or disclosed only when used for the purposes that have been stated by the company as consented by the data subject;
- Protected with the implementation of reasonable security arrangements that prevent risk and loss of data; and
- Disposed/deleted once: (a) data is no longer considered necessary for legal/business purposes, or (b) at the request of the data subject.
In addition, the Data Controller shall be responsible for, and be able to demonstrate compliance with, the PDPA. The Data Controller holds the greatest responsibility for ensuring compliance to the PDPA.
