Data Protection and Privacy in detail
Data protection laws, such as the GDPR in Europe and the Data Protection Act in the UK, control how organisations collect, store and use personal data. Principles include that data is processed fairly and lawfully, collected for a specific purpose, kept accurate, kept no longer than necessary and held securely.
Individuals have rights, such as seeing the data held about them, correcting it and asking for its deletion. Organisations must get consent and report breaches. Privacy means control over your personal information. Understanding these laws helps you protect yourself and use data responsibly.
