A Chameleon Hash-based Method for Proving Execution of Business Processes

Remote work is becoming common for many companies due to the impact of COVID-19 pandemic. Companies need be able operate every business process with high reliability, even in circumstances where lack direct conversation or cross-checking makes it difficult confirm verify works have been done correctly. In recent years, cloud-based electronic contract services emerged, and by executing processes accordance workflows cloud, possible prove execution a remote environment. However, when person uses service that signs digitally without his/her own signature key, there problem associated reliability; nobody can really executed based on person's intention. One way solve apply principal-signing client-side trivial digital scheme. these do not provide proof pre-assigned members. this paper we propose chameleon hash-based method proving processes. This very easy verifier series workflow, including identity authentication, document edits approval, “the principals who are designated advance”. addition, since principal has intention editing document, show authenticity interpretation Act Electronic Signatures Certification Business. We developed prototype system implemented method. confirmed compute proposed at speed burdening PC during documents our daily works, easily
