What is Data Localization?
Data localization or data residency laws require that data about citizens or residents of a certain country should be collected, processed, or stored within that country, before being transferred overseas. Typically, the data can only be transferred after meeting local privacy or data protection laws, such as informing users how the information is used and obtaining their consent.
Data localization is based on the concept of data sovereignty, which states that data is subject to laws and governance rules of the nation or region where they were collected. Data sovereignty may require records relating to citizens or residents of a country to comply with that country’s personal or financial data processing laws. By contrast, data localization requires that the initial collection, processing and storage of those users first occur within their country’s borders.
Another aspect of data localization is that under certain circumstances, data relating to citizens or residents of a country must be deleted from foreign systems before being deleted from systems in the data subject’s local country.
This is part of a series of articles about data security.
Why Is Data Localization Important?
There are several reasons why data localization is considered important by various governments, businesses, and individuals. Some of the main reasons include:
One of the main motivations for data localization is the desire to keep sensitive data within the borders of a particular country to enhance its security. This can be particularly important for governments and businesses that handle sensitive information, such as personal data, financial data, and intellectual property.
Data localization can also be used to ensure that data is subject to specific privacy laws and regulations. For example, the European Union’s General Data Protection Regulation (GDPR) requires that personal data of EU citizens be stored and processed in a way that ensures appropriate protection of their privacy.
Economic considerations
Some countries see data localization as a way to boost their domestic economy by requiring companies to store and process data within their borders. This can create local jobs and stimulate economic growth.
National sovereignty
Some governments may see data localization as a way to assert their national sovereignty and control over their citizens’ data. They may view data stored abroad as being outside their jurisdiction and therefore less subject to their laws and regulations.
Improved performance
Keeping data closer to users can also improve the performance of certain services, such as online applications and websites. This is because data has to travel a shorter distance, resulting in faster access and lower latency.
What Is the Difference Between Data Residency, Data Sovereignty and Data Localization?
Data residency, data sovereignty, and data localization are all related concepts that involve the storage and processing of data within a specific geographic location. However, they can have slightly different meanings depending on the context in which they are used.
Here is a brief overview of each concept:
Data Residency
Data residency refers to the physical location where data is stored. It refers to the actual location of the servers and other infrastructure that are used to store and process data. Data residency can be important for compliance with laws and regulations that require certain types of data to be stored within a specific country or region.
Data Sovereignty
Data sovereignty refers to the legal authority of a government or other entity to exercise control over data within its borders. It involves the ability of a government or other entity to regulate the collection, storage, use, and transfer of data within its jurisdiction.
Data Localization
Data localization refers to the practice of storing and processing data within a specific geographic location. It can be motivated by various factors, such as national laws or regulations, security and privacy concerns, or the desire to keep data closer to users. Data localization can involve both data residency and data sovereignty, as it involves the physical storage of data within a specific location and the legal authority to exercise control over that data.
How Does Data Localization Work?
Data localization involves storing and processing data within a specific geographic location. There are various ways in which this can be done, depending on the type and volume of data involved, as well as the specific requirements of the laws and regulations that apply. Some common approaches to data localization include:
On-premises Storage
One way to store data locally is to keep it on physical servers or other storage devices that are located within the borders of a particular country. This can involve building or renting a data center within the country, or using servers and storage devices that are owned and operated by a local company.
Cloud Storage
Another option is to store data in a cloud environment that is located within the borders of a particular country. This can involve using a cloud provider that has data centers within the country, or setting up a private cloud that is operated by a local company or organization.
Data Transfer
In some cases, data may need to be transferred from one location to another in order to comply with data localization requirements. This can involve moving data from one data center to another, or transferring data between different storage or processing environments.
Data Processing
Data localization may also involve processing data within a specific geographic location. This can involve using local servers, storage, and other infrastructure to process data, or using cloud-based processing services that are operated within the country.
In order to implement data localization, companies may need to invest in additional infrastructure, such as servers, storage, and networking equipment. They may also need to comply with various laws and regulations that govern the storage and processing of data within a specific location.
Data Localization: Pros and Cons
There are both advantages and challenges to implementing data localization, depending on the specific context in which it is used. Here are common advantages and challenges to consider:
Pros of data localization:
- Data security: One of the main advantages of data localization is that it can enhance the security of data by keeping it within the borders of a particular country. This can be particularly important for governments and businesses that handle sensitive information.
- Data privacy: Data localization can also help to ensure that data is subject to specific privacy laws and regulations, which can be important for protecting personal data and other sensitive information.
- Economic considerations: Data localization can also have economic benefits, such as the creation of local jobs and the stimulation of economic growth within a particular country.
- Improved performance: Data localization can also improve the performance of certain services, such as online applications and websites, by keeping data closer to users.
Cons of data localization:
- Cost: One of the main challenges of data localization is the cost involved in implementing it. This can include the cost of building or renting data centers and other infrastructure, as well as the cost of complying with laws and regulations.
- Complexity: Data localization can also be complex to implement, particularly if it involves transferring data between different locations or complying with multiple laws and regulations.
- Limited access: Data localization can also limit access to data, as it may not be easily accessible to users or businesses located outside the country in which it is stored.
- Trade barriers: Data localization can also create trade barriers, as it may make it more difficult for companies to operate across borders or to access data stored in other countries. This can have negative implications for global trade and economic growth.
