Design of heterogeneous integrated digital signature system for ensuring platform independence

Recently, digital transactions in real estate, insurance, etc. have become popular, and researchers are actively studying digital signatures as a method for distinguishing individuals. However, existing digital signature systems have different methods for making signatures depending on the platform and device, and because they are used on platforms owned by corporations, they have the disadvantage of being highly platform-dependent and having low software extensibility. Therefore, in this paper we have analyzed existing digital signature systems and designed a heterogeneous integrated digital signature system which has per-user contract management features and can guarantee platform independence and increase the ease of software extension and maintenance by using a browser environment.
