Prior art disclosure. This specification defines the Regulated Professional Identity Key Composite (RPIKC), a multi-factor identity architecture in which a regulated professional's cryptographic key forms an irremovable component of every user's digital identity within a distributed computational system. The primary embodiment uses a lawyer (the Lawyer Identity Key Composite, or LIKC), but the architecture extends to any regulated professional whose practice is governed by a jurisdictional regulatory body — including accountants, bookkeepers, auditors, financial advisors, notaries, and other professionals whose regulatory obligations create the accountability and trust properties the architecture requires. The RPIKC addresses three problems simultaneously: identity verification (eliminating bots, trolls, and synthetic identities through real-world professional relationships), identity protection (placing user identities under professional privilege from the point of creation), and identity lifecycle management (providing every user with a professional relationship that persists across the full lifecycle of their digital identity including succession and recovery). The architecture is further specified as a social media sign-on protocol, enabling RPIKC-verified identity to serve as a universal authentication mechanism across platforms, applications, and services — replacing existing sign-on protocols (OAuth, OpenID Connect, SAML, social login via Google/Facebook/Apple) with an identity that is verified by a regulated professional, protected by professional privilege, and managed across its full lifecycle. The mechanism is described within the context of a broader computational identity standard which provides globally unique, immutable hash-chain addressing for computational functions. However, the RPIKC is architecturally independent and applicable to any distributed system requiring verified, privileged, recoverable digital identity, and as a social media sign-on protocol for any platform requiring robust identity verification. The RPIKC is, to the author's knowledge, a novel contribution to the fields of digital identity, distributed systems, social media authentication, and computational law. No prior art combining regulated professional credentials as cryptographic identity components with hash-chain concatenation, nor using such credentials as a social media sign-on protocol, has been identified.
