Fingerprints are used to identify human and for crime discover. They are used to authenticate persons in order to allow them to gain access to their financial and personal resources or to identify them in big databases. This requires use of fast search engine to reduce time consumed in searching big fingerprint databases, there for choosing searching engine is an important issue to reduce searching time. This paper investigates the existing searching engine methods and presents advantages of AVL tree method over other methods. The paper will investigate searching speed and time consuming to retrieve fingerprint image. Experiment shows use of AVL tree is the best searching algorithm.
