This is the most recent and up-to-date book on data protection in Ireland. This book is a comprehensive guide as to what data protection is and the implications and obligations for holders and subjects of such data. It covers the many changes that have occurred in Irish data protection law in recent times, including developments in areas such as 'social networking' and the implications of technologies, such as 'cookies.' The data protection regime applies internally to organizations, their employees, agents, contractors, etc. It also applies when an organization focuses outward at customers, potential customers, and users. Both 'inward' and 'outward' data protection issues are examined. Particular consideration is given to security, data loss, data breach, and penalties. The book also provides the first reference in Ireland to the many sources of data protection law, essential for keeping abreast of data protection issues. The draft EU Data Protection Regulation will bring large changes to the data protection regime, and these are referred to in detail. The recent changes to the data protection regime in the UK are also considered.
