Data Protection Act

Data Protection Act (1998)

As the quantity of sensitive data stored about users increases, it is important that legislation is in place to protect it.

Purpose of the DPA

The DPA was first published in 1998.
It determines what organisations can do with the personal data that they have collected.
The DPA also defines the rights of the individual over the data that is stored about them.
In 2018, the DPA was strengthened by the introduction of a new act called General Data Protection Regulation (GDPR).

Principles of the DPA

There are eight principles (rules) in the DPA.
The first four rules are:
- Data must be used and processed in a fair and lawful way.
- Data must only be used for the stated purpose.
- Data must be adequate, relevant and not excessive for the specified use.
- Data must be accurate and kept up-to-date.

Principles of the DPA

There are eight principles (rules) in the DPA.
The second four rules are:
- Data should not be kept longer than necessary.
- Data should only be used according to the rights of the data subject.
- Data should be kept safe and secure.
- Data must not be transferred to organisations within other countries that do not offer a similar level of protection.

The Data Protection Act 2018

The Data Protection Act 2018 is an updated data protection law, that brings the EU GDPR to UK law.
The Data Protection Act 1998 formed the origins of the GDPR law, but each act has its differences.
- The 'right to erasure' in each act is different - there are more exemptions in the 2018 version.
The Data Protection Act 2018 requires companies to run a GDPR audit.
