A digital certificate-based signature, or DCBS, is a legally-binding way to authenticate and sign documents without the need for physical authentication. It uses cryptographic techniques to provide secure and reliable digital signatures that are accepted by courts of law in many jurisdictions. With DCBS, individuals can securely transact business online, prove their identity, and verify messages and documents. DCBS also allows organizations to regulate access to systems, networks, and confidential data, helping ensure data security and privacy.
