Description: Graph anonymization refers to the techniques used to protect the privacy of data represented in graph structures, which are sets of nodes and edges representing relationships between entities. This process involves modifying the structure of the graph in such a way that the utility of the data for analysis and studies is preserved while hiding the identities of individual nodes. Anonymization techniques may include generalization, where similar nodes are grouped, and perturbation, which introduces random changes to the graph structure. Graph anonymization is crucial in contexts where sensitive data is handled, such as social networks, healthcare data, and recommendation systems, as it allows for analysis without compromising the privacy of individuals represented in the graph. The relevance of this technique lies in its ability to balance the need for useful data for research and analysis with the obligation to protect personal information, which is especially important in an increasingly privacy- and data security-conscious world.
