How to collect and use big data
Big data can be collected by an organisation from a large number of sources.
An organisation may seek to leverage big data using data analytics for a range of purposes.
Big data often constitutes personal information if any individuals to whom it relates are identifiable from the big data.
Data analytics often involves the collection and analysis by an organisation of big data that comprises the personal information of various individuals.
As it may not be possible or viable for an organisation to obtain the required consents from each individual whose personal information is being collected or analysed, the organisation may decide to utilise data anonymisation (or personal information “de-identification”) methods or techniques, to enable the organisation to collect, analyse and process big data that comprises personal information without breaching the Privacy Act 1988 (Cth) (Privacy Act) or confidentiality.
