3D Reconstruction of Face Image Authentication Technology in Electronic Transaction Authentication

In order to improve the reliability of electronic transactions, it is necessary to study more stringent and effective methods of identification and authentication. Face recognition technology has been applied in electronic trading, but it has not been widely promoted on a global scale. In view of this, based on the 3D modeling technology, this study combines the actual situation to carry out the demand analysis. Moreover, on this basis, the face feature recognition process is set. In addition, based on the needs of network finance for identity recognition and authentication and the characteristics and deficiencies of face image identification and authentication methods, this paper proposes an image-based identity recognition and authentication method for systems to be more strictly authenticated. Finally, this paper sets the comparative experiment to compare the performance of the algorithm. The results show that the proposed algorithm has certain practical effects and can provide theoretical reference for related research.
