A Person Retrieval Solution Using Finger Vein Patterns

Personal identification based on finger vein patterns is a newly developed biometrics technique and several practical systems have been deployed recent years. We developed a finger vein verification system for checking attendance and have collected a database of 0.8 million finger vein samples. Based on the database, we proposed a person retrieval solution for searching an image in the database and can get the response in an acceptable time. To fit for the retrieval solution, we designed a new encoding method. The experimental results show that our solution can get a result in about 10 seconds when working on a database of 50,700 samples. In the same time, the error rate is nearly the same as the linear searching.
