论文摘要
指纹身份验证技术已在各种物联网（IoT）应用程序（IoT）应用程序中用于访问控制以保护私人数据，但是未经保护的物联网应用程序中的RAW指纹模板泄漏可能会使身份验证系统变得不安全。可取消的指纹模板可以有效防止隐私漏洞并为原始模板提供强大的保护。但是，为了适应资源约束的物联网设备，过度简化的模板会严重损害身份验证性能。此外，通常修复了现有的可取消指纹模板的长度，因此很难将其部署在各种内存限制的IoT设备中。为了解决这些问题，我们建议在各种资源约束的物联网应用程序中，为隐私保护身份验证系统提供一个新颖的长度轻巧的可取消指纹模板。提出的可取消模板设计主要由两个组成部分组成：1）基于设计的重新索引方案的长度柔滑偏度偏度特征生成； 2）基于设计的编码nest-nest-Difference-XOR方案的轻巧可取消功能生成。公共数据库的全面实验结果〜FVC2002 DB1-DB4和FVC2004 DB1-DB4表明，提议的可取消的指纹模板可实现等效的身份验证性能，以与IOT环境中的最新方法相同，但是我们的设计大大降低了模板存储空间和计算成本。更重要的是，提出的长度可轻巧的可取消模板适用于各种商业智能卡（例如，C5-m.o.s.t。CantConfince Micropopersess智能卡CLXSU064KC5）。据我们所知，提出的方法是第一个用于资源受限的物联网应用程序的轻巧，高效的可取消指纹模板设计。
Fingerprint authentication techniques have been employed in various Internet of Things (IoT) applications for access control to protect private data, but raw fingerprint template leakage in unprotected IoT applications may render the authentication system insecure. Cancelable fingerprint templates can effectively prevent privacy breaches and provide strong protection to the original templates. However, to suit resource-constrained IoT devices, oversimplified templates would compromise authentication performance significantly. In addition, the length of existing cancelable fingerprint templates is usually fixed, making them difficult to be deployed in various memory-limited IoT devices. To address these issues, we propose a novel length-flexible lightweight cancelable fingerprint template for privacy-preserving authentication systems in various resource-constrained IoT applications. The proposed cancelable template design primarily consists of two components: 1) length-flexible partial-cancelable feature generation based on the designed re-indexing scheme; and 2) lightweight cancelable feature generation based on the designed encoding-nested-difference-XOR scheme. Comprehensive experimental results on public databases~FVC2002 DB1-DB4 and FVC2004 DB1-DB4 demonstrate that the proposed cancelable fingerprint template achieves equivalent authentication performance to state-of-the-art methods in IoT environments, but our design substantially reduces template storage space and computational cost. More importantly, the proposed length-flexible lightweight cancelable template is suitable for a variety of commercial smart cards (e.g., C5-M.O.S.T. Card Contact Microprocessor Smart Cards CLXSU064KC5). To the best of our knowledge, the proposed method is the first length-flexible lightweight, high-performing cancelable fingerprint template design for resource-constrained IoT applications.
