SARS-CoV2 pandemic is heavily affecting our lives. Many actions have been undertaken to slow down its expansion and, among the others, contact tracing applications are the less invasive to monitor the spread of the virus. The idea behind contact tracing is to track contacts between people by the exchange of identifiers, not linked to individuals, exploiting the use of Bluetooth Low Energy (BLE) technology to estimate the duration and proximity of contacts. The data collected in this way is used for the sole purpose of notifying a potential contact with an infected person without revealing their identity and location. This paper presents a contact tracing protocol based on technology that exploits for reporting contacts at risk of contagion. The novelty of the proposed solution is the use of Non Fungible Tokens (NFT) to guarantee user privacy through a decentralized approach, equipped with a reliable non-proprietary notification mechanism that allows public access to anonymous infections data.
新冠疫情严重影响着我们的生活。人们采取了许多行动来减缓其传播，其中，接触者追踪应用是监测病毒传播侵入性较小的方式。接触者追踪背后的理念是通过交换不与个人相关联的标识符来追踪人与人之间的接触，利用低功耗蓝牙（BLE）技术来估计接触的持续时间和距离。以这种方式收集的数据仅用于通知与感染者的潜在接触，而不透露其身份和位置。本文提出了一种基于 技术的接触者追踪协议，该技术利用 来报告有传染风险的接触。所提解决方案的新颖之处在于使用非同质化代币（NFT），通过去中心化方法保证用户隐私，配备可靠的非专有通知机制，允许公众访问匿名感染数据。
