Data Protection Act 1998 

The Data Protection Act (DPA) is a United Kingdom Act of Parliament. It defines a legal basis for the handling in the UK of information relating to living people. It is the main piece of legislation that governs protection of personal data in the UK. Although the Act does not mention privacy, in practice it provides a way in which individuals can enforce the control of information about themselves. Most of the Act does not apply to domestic use,1 for example keeping a personal address book. Organisations in the UK are legally obliged to comply with this Act, subject to some exemptions.

Compliance with the Act is enforced by an independent government authority, the Information Commissioner's Office (ICO). The ICO maintains guidance relating to the Act.2

The Act defines eight principles of information-handling practice.

The UK Data Protection Act is a large Act that has a reputation for complexity.3 While the basic principles are honoured for protecting privacy, interpreting the act is not always simple. Many companies, organisations and individuals seem very unsure of the aims, content and principles of the DPA. Some hide behind the Act and refuse to provide even very basic, publicly available material quoting the Act as a restriction.4 The act also impacts on the way in which organisations conduct business in terms of who can be contacted for marketing purposes, not only by telephone and direct mail, but also electronically and has led to the development of permission based marketing strategies.

Plain-language summary of key principles

This section provides a quick overview of what the Key Principles of information-handling practice mean. The Key Principles themselves are discussed below in the context of their definition in law.

Also subjects are allowed/have the right to make changes to wrong information

Personal data

The Data Protection Act covers any data which can be used to identify a living or of an ethical race person. This includes names, birthday and anniversary dates, addresses, telephone numbers, Fax numbers, e-mail addresses etc. It only applies to that data which is held, or intended to be held, on computers ('equipment operating automatically in response to instructions given for that purpose'), or held in a 'relevant filing system'.

It should be noted that an ordinary paper diary can be classified as a 'relevant filing system' if it can be demonstrated that the diary is used to support commercial activities (eg, a Salesperson's diary).

Subject rights

The Data Protection Act creates rights for those who have their data stored, and responsibilities for those who store or collect personal data.

The person who has their data processed has the right to5

Data protection principles

  1. Personal data shall be processed fairly and lawfully and, in particular, shall not be processed unless-
    1. at least one of the conditions in Schedule 2 is met, and
    2. in the case of sensitive personal data, at least one of the conditions in Schedule 3 is also met.
  2. Personal data shall be obtained only for one or more specified and lawful purposes, and shall not be further processed in any manner incompatible with that purpose or those purposes.
  3. Personal data shall be adequate, relevant and not excessive in relation to the purpose or purposes for which they are processed.
  4. Personal data shall be accurate and, where necessary, kept up to date.
  5. Personal data processed for any purpose or purposes shall not be kept for longer than is necessary for that purpose or those purposes.
  6. Personal data shall be processed in accordance with the rights of data subjects under this Act.
  7. Appropriate technical and organisational measures shall be taken against unauthorised or unlawful processing of personal data and against accidental loss or destruction of, or damage to, personal data.
  8. Personal data shall not be transferred to a country or territory outside the European Economic Area unless that country or territory ensures an adequate level of protection for the rights and freedoms of data subjects in relation to the processing of personal data.

Conditions relevant to the first principle

Exemptions

The Act is structured such that all processing of personal data is covered by the act, while providing a number of exemptions in Part IV.1 Notable exemptions are:

Offences

Apparent flaws in the Act

Several apparent flaws may be found in the text of The Act. The definition of personal data is data which relates to a living individual who can be identified:—

This is a subjective definition since whether particular data is personal data depends on which data controller is referred to in the definition. Elsewhere in the act the definition of what constitutes personal data is generally treated as objective.

The effect of this is that personal data encrypted with asymmetric cryptography using a third party's public key is not itself personal data. Such encrypted data alone cannot be used to identify an individual, and the necessary private key is not likely to come into the possession of the data controller. Since the encrypted data is not personal data, none of the provisions of The Act apply.

Another issue arises from the mutually recursive definition of data controller. The data controller is a person who determines the purposes for which and the manner in which any personal data is, or is to be, processed. However the personal data is defined above according to the likely availability of information available to the data controller. This mutual recursion makes the determination of what is and what isn't personal data formally undecidable in some circumstances.

One potential effect of such flaws is that data processing systems can readily be devised which circumvent the spirit but not the letter of The Act.

Personal data which is normally held for under 40 days may be legitimately denied in Subject Access Requests under The Act. This is a consequence of the time limit Data Controllers must meet in making their response. If the data has been deleted by the normal procedures of the business by the time the Data Controller responds to a request, that data cannot be supplied. For data such as CCTV images which are routinely overwritten, it may be impossible for a subject to exercise their data access rights.
