Abstract
The COVID-19 pandemic changed the lives of millions of citizens worldwide in the manner they live and work to the
so-called new norm in social standards. In addition to the extraordinary effects on society, the pandemic created a range of
unique circumstances associated with cybercrime that also affected society and business. The anxiety due to the pandemic
increased the probability of successful cyberattacks and as well as number and range. For public health officials and
communities, location tracking is an essential component in the their efforts to combat the disease. The governments
provide a lot of mobile apps to help health officials to trace the infected persons and contact them to aid and follow up on
the health status, which requires an exchange of data in different forms. This paper presents the one-time stamp model as a
new cryptography technique to secure different contact forms and protect the privacy of the infected person. The one-time
stamp hybrid model consists of a combination of symmetric, asymmetric, and hashing cryptography in an entirely new way
that is different from conventional and similar existing algorithms. Several experiments have been carried out to analyze
and examine the proposed technique. Also, a comparison study has been made between our proposed technique and other
state-of-the-art alternatives. Results show that the proposed one-time stamp model provides a high level of security for the
encryption of sensitive data relative to other similar techniques with no extra computational cost besides faster processing
time.
