1. Data-Mining and Record-Matching

2. Whenever you fill out a form for an organisation, business or government, the information usually ends up being stored in a database on a computer somewhere. Data-Mining involves analysing the information to determine the types of people that have filled out the form. In order to build an electronic profile, records from various databases need to be collated and this is done through matching a particular item of data (or field) that is common in both databases. This is the reason why some governments insist that all citizens have an ID number to make the matching of records easier. This process is called Record- Matching.

3. The goal of data-mining is to discover hidden facts contained in databases by finding patterns and relationships in data, and inferring rules that allow the prediction of future results. Typical application include customer profiling for the purposes of advertising and the identification or patterns of behaviour for fraud detection. The natural extension of data-mining is sharing or selling of information stored in databases, record-matching and the building of electronic profiles.

4. Easy way finding records. Getting someone’s detail with ID numbers. Life's is actually all about codes (Lisa's quotes) Hackers – people can hack into the files without authorisation. People can get details which is private and not permitted. Random people could call you and stalk you.
