Code of Data Matching Practice
The use of data for data matching purposes is governed by the C&AG’s Code of Data Matching Practice, the purpose of which is to help ensure that the C&AG, the Northern Ireland Audit Office, and all persons and bodies involved in data matching exercises comply with the law, especially the provisions of data protection legislation, and to promote good practice in data matching. The original Code was prepared in consultation with the Information Commissioner and other stakeholders and was laid by the Department of Finance and Personnel before the Assembly on 25 July 2008. The following link will take you to the Code of Data Matching Practice.
The Code of Data Matching Practice is currently being updated for changes to data protection legislation and for developments in data matching arrangements. A copy of the draft Code for consultation is at the link below. Anyone wishing to provide comments on the draft Code may do so by emailing firstname.lastname@example.org by 1st October 2018.
