How Surety’s hash-and-link trusted time-stamp technology compares with the most commonly used data-level security procedures. An overview comparing AbsoluteProof® to secure hashing, PKI timestamps, or PKI digital signatures shows that not all timestamp technologies are the same.
AbsoluteProof® offers trusted time value, is portable, offers long-lived integrity, detects tampering, is independently verifiable, is standards-based and is non-reputable— a package of capabilities that secure hashing, PKI timestamps and PKI digital signature cannot offer.
