COS (Connected Open Signatures)

Connected Open Signatures (COS) is a technology that allows digital signatures to be securely linked to a network or blockchain, ensuring the authenticity and integrity of the signed data. When a document or message is signed using COS, it creates a tamper-proof record that can be independently verified online. This guarantees that the signature is genuine and has not been altered, providing trust and transparency in digital transactions. COS is particularly useful for industries requiring secure digital certifications, legal agreements, and sensitive communications, enabling reliable validation across connected digital environments.
