GNNs utilize graphs to construct an embedding that includes details about the nodes and edges in a graph\u2019s neighborhood. In this work, a set of Region Adjacency Graphs (RAG) derives the attribute values from Static Signature (SS) images. These attribute values are used to label the nodes of the complete graph, which is formed by considering each signature as a node taken from the sample of signatures of a specific signer. The complete graph is trained by using GraphSAGE, an inductive representation learning method. This trained model helps to determine any newly introduced node (static signature to be tested) as genuine or fake. Standard static signature datasets, notably GPDSsynthetic and MCYT-75 are used to test the prevailing model. Experimental results on genuine and counterfeit signature networks demonstrate that our computed model enables a high rate of accuracy (GPDSsynthetic 99.91% and MCYT-75 99.56%) and minimum range of loss (GPDSsynthetic 0.0061 and MCYT-75 0.0070) on node classification.<\/jats:p>","DOI":"10.3233\/jifs-231369","type":"journal-article","created":{"date-parts":[[2024,1,30]],"date-time":"2024-01-30T11:44:00Z","timestamp":1706615040000},"page":"6977-6994","source":"Crossref","is-referenced-by-count":0,"title":["Region
