Screen4 are one of the world’s leading providers of health screening services, and have been involved in drug and alcohol testing for the aviation sector, as well as other operators of safety-critical services, for many years. With operations at 140 locations in 40 countries they have a truly global reach from their headquarters in Barnsley, Yorkshire.
When the Covid-19 pandemic hit Europe in March 2020, Screen4 developed a range of testing services to establish whether individuals had become infected with the coronavirus, or indeed had developed antibodies against the virus. During the latter part of 2020 a project was initiated through S4Encrypt to apply the highly secure Safe4 vault capability as a means of delivering Covid-19 test results to people who had been tested for travel purposes. This application went live in December 2020.
The process is initiated when a traveller purchases a PCR test from the Screen4 website. This sends a call via the Safe4 API to invite the individual concerned to create a secure account. The unique barcode for the test is entered into the account when the test is taken, and the sample sent off to the laboratory in Cambridge. When the result has been determined by the lab it is sent back to Screen4 and placed into the individual’s secure account, again through the Safe4 API. The individual is sent a notification advising that the test result is available in their account, from where a PDF certificate can be printed. Alternatively, the result can also be downloaded to the e-wallet on a smartphone. Both the certificate and the e-wallet carry a QR code that, when scanned, will provide independent verification of the result direct from the Safe4 secure website.
More than 200,000 tests have been processed since December 2020. The service will shortly be extended to include lateral flow tests, again with a focus on international travel.
The security of the Safe4 personal vault is the key to the success of this project. Highly confidential personal health information is delivered without recourse to unsafe methods, such as email. The international traveller, whether travelling to or from the United Kingdom, is thus able to comply with public health regulations conveniently and very efficiently.
