Wisekey provides IoT early warning for Covid-19

Swiss firm Wisekey is partnering with global technology organisations to provide an IoT early warning system that can be used to facilitate early detection of viruses and future outbreaks.
 
Wisekey is teaming with several partners to develop the IoT early warning system (EWS) designed with the objective of saving lives through early detection as one of the main technology integrations to help prevent the spread of Covid-19. As a result, cyber security, IoT and artificial intelligence (AI) are being used to help predict future outbreak areas.
 
Leveraging IoT sensors equipped with the WIShelter app capable of measuring temperature and providing geolocation of targeted quarantines, the technology can help mitigate the spread of the coronavirus. IoT, a network of interconnected systems and advances in digital certification, data analytics, AI and connectivity, can help by providing an early warning system to curb the spread of infectious diseases.
 
The simple answer might for enterprises, cities, and national governments to create collectively a massive global network of sensors. This network could detect the spread of viruses by combining the anonymised digital identity with the behaviour of a person. However, this would require standardisation, planning and implementation on a global scale and a special focus on privacy to develop the early warning system.
 
Lack of security increases the risk of users’ personal information being hacked while the data are collected and transmitted to the IoT device. IoT devices are connected with a consumer network, and sometimes unauthorised users might exploit existing security vulnerabilities if the infrastructure is not properly secured.
 
EWS is a core type of data driven IoT systems. The potential benefits of using a semantic-type EWS include easier sensor and data source plug-and-play, simpler, richer and more dynamic metadata-driven data analysis, and easier service interoperability and orchestration.
 
The IoT can live up to its promise only if the connected devices, the data they generate, the business applications that control these devices and the services around them can be fully secured and trusted. In today’s environment, where cyber attacks have become more common and increasingly sophisticated, there is an urgent need to rethink the security stack for the IoT cloud.
 
IoT-enabled services and products will generate vast amounts of data which, when well analysed, will be very valuable to government organisations, product manufactures, corporations and end-users. Users can take advantage of this in the market by remotely being able to identify uniquely and control an IoT edge device, securely provision the IoT edge device credentials, and secure the messages in motion between edge devices and business applications.
 
The first phase of the low-power Bluetooth 5 secure beacon implementation was developed using Wisekey’s Vault IC407, the RSL10 and N34TS108 temperature sensor from On Semiconductor, as well as Tatwah’s BLE IT-005 IP68 class beacon. The device has a long battery life, with no compromise to security. The secure implementation allows replay attack protection, device clone protection, Vault IC absence detection, revocation capability, measurement validity check and true temperature display.
 
Wisekey has combined a complete set of technologies to guarantee health data integrity and confidentiality.
 
A secure element is added to the RPM device to protect the data at source and encrypt and digitally sign them over a Bluetooth Low Energy (BLE) connection to a local communication gateway. This secure element is either a certified Vault IC407 added to the device microprocessor or a secure enclave of this microprocessor based on Wisekey’s security IPs.
 
Patients’ drugs containers and other sensitive consumables can be equipped with Nano Seal RT, Wisekey’s NFC product, to provide any object with a communication channel for authentication, tracking or interactivity purpose.
 
A local gateway connects all medical devices at home to the HDO server through a 5G network. Similarly to connected devices, the gateway contains a Vault IC407 or Wisekey’s security IPs to protect the local BLE network of medical devices and guarantee the health data integrity and confidentiality until the HDO server.
 
Wisekey’s VaultiTrust service for secure data generation and injection into secure elements is at the heart of this infrastructure. It provides any object with a strong digital identity.
 
On the HDO server, patient’s medical data are still managed under a consistent security scheme with Wisekey’s public key infrastructure (PKI) based on the Oiste Foundation root-of-trust. Blockchain technology is used whenever a secured distributed ledger must assure the ubiquitous availability of the data.
