The privacy lifecycle is the sequence of stages that personal data moves through, from the moment it is first collected until it is finally distributed or deleted. These stages are usually defined as collection, aggregation and analysis, storage, use, and distribution. Each stage raises unique risks for human dignity and personal rights, which must be addressed if technology is to be fair and accountable.
Understanding the privacy lifecycle is essential in the age of artificial intelligence, where massive amounts of personal data are used to train and operate systems. At the collection stage, people deserve protection against unnecessary or invasive surveillance. During aggregation and analysis, the danger lies in unfair profiling or drawing conclusions that reinforce bias. Storage creates risks of breach, theft, or loss of confidentiality. The use of data raises the question of whether it is applied in ways that respect consent and legitimate purpose. Finally, distribution must be controlled so that individuals are not exposed to harmful or exploitative data sharing.
Recognizing privacy as a lifecycle, rather than a one-time event, reinforces the principle that human beings should never lose ownership of their data. Every stage of this process requires safeguards that uphold privacy, data protection, and accountability.
