The UK Data Protection Act 2018 emphasizes the principle of data minimization, which requires that the data collected and processed should be adequate, relevant, and limited to what is necessary in relation to the purposes for which they are processed. The Act also underscores the importance of data accuracy, obligating organizations to ensure that personal data is accurate and, where necessary, kept up to date. Lastly, the Act introduces the principle of accountability, stipulating that the controller is responsible for demonstrating compliance with these principles
Organizations must also ensure that personal data is accurate and up to date, taking reasonable steps to erase or rectify inaccuracies without delay. Furthermore, organizations must guarantee they are not retaining personal data for longer than necessary in relation to the purpose for which they were collected.
Under the UK Data Protection Act 2018, organizations must obtain explicit consent from individuals before processing their personal data, unless there is another lawful basis. This consent must be freely given, specific, informed, and unambiguous, and must be made by a statement or a clear affirmative action. In sensitive personal data, explicit consent is required, and blanket consent without specifying the purpose of processing is unacceptable. Individuals have the right to withdraw consent at any time, and organizations must inform them about their right to withdraw before consent is given.
Beyond this, the UK Data Protection Act 2018 requires the implementation of appropriate security measures, including protection against unlawful or unauthorized data processing, access, accidental loss, destruction, or damage. These measures include encryption and pseudonymization, maintaining ongoing confidentiality, integrity, availability, and resilience of processing systems and services, regularly testing and evaluating the effectiveness of these measures, and restoring availability and access to personal data in the event of a physical or technical incident
