| Abstract: | Using the design idea of the structure of graphs and number theory, we applied the labelling to the study of graphical password, gaveand proved the set ordered graceful labelling, the strongly graceful labelling, properties of some vertices and the odd graceful labelling which was formed by adding the leaves of each vertex. |

| Keywords: | set ordered graceful labelling strongly graceful labelling hierarchical graph odd graceful labelling graphical password |
