概括
本研究介绍了一种安全的,可取消的生物识别系统,使用表面电肌图 (sEMG) 信号从手势来验证无线身体区域网络 (WBAN). 新的框架通过使用户能够重置受损的生物识别令牌来增强安全性和隐私.
科学领域:
- 生物识别和网络安全
- 信号处理和机器学习
- 物联网 (IoT) 安全 安全 物联网
背景情况:
- 像指纹这样的传统生物识别数据,由于其不可取消的性质,会带来隐私风险.
- 暴露的生物识别模板无法更改,导致潜在的隐私侵犯.
- 基于无线人体区域网络 (WBAN) 的物联网 (IoT) 应用程序需要强大而安全的用户身份验证.
研究的目的:
- 提出一个新的安全EMG框架,用于WBAN-IoT中可取消的生物识别身份验证.
- 通过使用手势编码的表面电肌图 (sEMG) 信号来增强信息安全和用户隐私.
- 让用户能够重置受损的生物识别令牌,从而提高系统的安全性和可靠性.
主要方法:
- 在16次静态手/手腕运动中,从前臂肌肉 (flexor carpi ulnaris) 收集的sEMG信号.
- 应用纯频击波器 (5-500 Hz) 来降低噪音,并提取时间域特征.
- 实现了调整式提升完美分类器,用于准确的分类和匹配得分计算.
主要成果:
- 实现了99.72%的高认证准确率.
- 获得了96.0%的F1得分,表明了强大的分类表现.
- 记录了一个非常低的等错率 (EER) 0.0037,证明了稳定性.
结论:
- 安全的EMG框架为WBAN-IoT认证提供了可靠和安全的可取消生物识别解决方案.
- 使用sEMG信号与手势相结合,提供了一个独特的,保护隐私的生物识别令牌.
- 拟议的方法有效地解决了传统生物识别的局限性,提高了整体系统的安全性.

Hand hygiene
5.6K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

The American Nurses Association (ANA) created and implemented the first nationally accepted Code of Ethics for Nurses with Interpretive Statements. The Code of Ethics is a living document regularly updated by the ANA and establishes an ethical standard that is non-negotiable for nurses in all roles and settings.
The Code of Ethics provisions outline the nurse's duty to the patient, the healthcare team, the profession, and society. The Code's fundamental principles include advocacy,...
