Trusted Electronic Signature According to Thai Laws using UTXO Blockchain

Utharn Buranasaksee, Pitchya Tangsombatvichit

Abstract


Before the COVID-19 epidemic, getting the document printed and signed among the parties in the company are not that difficult. Since everyone is working onsite, taking several hours in the company collecting for the signature on paper is worth legal enforcement. During the epidemic, many government agencies and companies have adopted a new working style by having the employee remotely work from home. However, the employees do just have only online meetings, or can the employee remotely work become a real concern. In this case, getting the signature might take several days to weeks since the parties are remotely located. According to Thai laws, signing on important matters such as accounting or legal would still require a signature on the paper or a trusted electronic signature.  The general solution is to leverage digital certificates issued by Certification Authority (CA) to provide trusted electronic signatures. In this paper, we analyze the cost and security of the existing solutions. A novel trusted electronic signature solution is proposed. We show that the proposed approach greatly reduces the cost while the security level is maintained.
