Footprint Identification: Review of an Emerging Biometric Trait

Biometric systems are progressively replacing traditional password‐based and token‐based validation systems. Security and acknowledgment precision are the two most significant viewpoints to be considered in developing a biometric system. Today, biometric has been effectively conveyed in different fields like criminological science, security, distinguishing proof, and approval systems. In this study, a complete survey is introduced to reveal insight into the most recent advancements in the investigation of footprint‐based individual recognition covering different angles that have been utilized by scientists to improve this biometric modality. The paper presents various techniques developed so far for recognizing a person's identity using foot geometry and footprint structure. Because of a careful examination and conversation, impediments of existing exploration work are discussed and recommendations for future work are given.
