本文探讨手部生物特征在数字取证中的应用,通过手部几何验证方法解决指纹或掌纹不可用时的身份验证问题,并分析了多种单模态与多模态手部生物特征识别技术。

摘要:

数字取证现已成为保护数字世界免受身份盗窃的不可或缺的环节。面对更高阶的犯罪,处理海量数据库对任何智能系统而言都是极具挑战性的难题。生物特征识别是克服数字取证所遇问题的更优解决方案。过去数十年来,多种生物特征在取证领域发挥了重要作用。本文通过阐述手部几何验证方法,探讨了基于手部模式的取证应用的优势与前景。当有效的生物特征证据无法获取时,例如手套破损,以及污垢或任何液体可能降低指纹或掌纹的可获取性与可靠性时,该方法便可发挥作用。由于在超大规模数据库中手部特征缺乏绝对唯一性,该方法可能仅适用于验证。本文还讨论了多种单模态与多模态的基于手部的生物特征识别方法(如手部几何、掌纹和手部静脉),涵盖了多种特征提取、数据库和验证方法,并涉及2D、3D及红外图像。

英文摘要:

Digital forensic is now an unavoidable part for securing the digital world from identity theft. Higher order of crimes, dealing with a massive database is really very challenging problem for any intelligent system. Biometric is a better solution to win over the problems encountered by digital forensics. Many biometric characteristics are playing their significant roles in forensics over the decades. The potential benefits and scope of hand based modes in forensics have been investigated with an illustration of hand geometry verifi-cation method. It can be applied when effective biometric evidences are properly unavailable; gloves are damaged, and dirt or any kind of liquid can minimize the accessibility and reliability of the fingerprint or palmprint. Due to the crisis of pure uniqueness of hand features for a very large database, it may be relevant for verification only. Some unimodal and multimodal hand based biometrics (e.g. hand geometry, palmprint and hand vein) with several feature extractions, database and verification methods have been discussed with 2D, 3D and infrared images.
