The Scottish Government has published its guidance document on Identity Management and Privacy Principles. The guidance is aimed at both public sector policy makers and with those involved in devising or operating systems for proving or recording identity. Key principles include:

  • For services which are used frequently and for which identification is needed, users should be required to register only once. Thereafter, unless there is a statutory requirement to prove identity, a person should generally be able to access the service by authenticating themselves using a token (such as a bus pass or library card) that proves their entitlement without revealing personal information. In other circumstances, a user name and a password may be required.
  • A Privacy Impact Assessment (PIA) or proportionate equivalent should be conducted and published prior to the implementation of a project which involves the collection of personal information.
  • Where a public body has a contract with the private sector or the third sector, the contractor must be contractually bound to adhere to best practice as outlined in the guidance.
  • The creation of centralised databases of personal information is to be avoided.
  • If a public service organisation needs to link personal information from different systems and databases (internally or between organisations), it should avoid sharing persistent identifiers. Instead, other mechanisms – such as matching – should be considered.
