Types of electronic signature in Paraguay
Electronic signature
Electronic data identifying the signer. It is valid; if challenged, whoever invokes it must prove authorship — Firmiu's audit trail plays that role.
Qualified electronic signature
Created with a qualified certificate from a provider accredited before MITIC (Law 6822/2021). It equals a handwritten signature and enjoys presumptions of authorship and integrity.
