# **not.bot™ Use Cases: Index** This index is the top-level catalog of not.bot use cases: each use case in one line, grouped by category, with links to the six detail documents that give each its full treatment. The catalog grows as new use cases surface. --- ## **Mechanisms** The use cases draw on a small set of underlying mechanisms. The definitions here are referenced from each detail document. **Signature.** A cryptographic stamp on content or an action, biometric-gated at the moment of signing, bound to a passport-verified human. Visible as a QR or JAB code embedded in the content. **Site pass.** A per-human, per-site identifier derived through multiparty computation. The same human cannot create two site passes for the same site even using different aliases. **Credential.** A verifiable claim issued by an identity (human or Business DID) about another identity. Credentials carry validity windows, scope, and revocation rules. Holders present credentials to verifiers on a selective basis. **Alias.** A separate identity under the same passport-verified human, cryptographically unlinkable to the human's other aliases. Lets a person maintain different presentations across different contexts. **Business DID.** An organizational identity governed by human signers through delegation. Actions under a Business DID trace back to a specific human key-holder. --- ## **Categories** ### **Enterprise** → [Enterprise Use Cases](http://doc_31_use_cases_enterprise.md) - **Human-level permissions auditing.** Map all permissions a specific human holds across systems without operational reconciliation. - **Prevent account sharing.** Bind authentication to biometric verification of a passport-verified human. - **Comprehensive offboarding.** Close all accounts associated with a departing human in one operation. - **Banning across an organization.** Surface a banned human at next authentication attempt, regardless of agency or business unit. - **Physical access control.** Replace badges and key fobs with biometric-gated cryptographic identity at each door read. - **Cross-system authorization.** Issue permission credentials to employees through Business DIDs. - **Time-limited vendor and contractor access.** Built-in expiration removes the offboarding ticket. - **Hiring and recruiting.** Verifiable employment history, education, certifications, and reference letters. - **Customer service authentication.** Replace knowledge-based authentication with cryptographic identity at support contacts. - **Supply chain attestations.** A verified human signs at each handoff for chain of custody. ### **Content signing** → [Content Signing Use Cases](http://doc_32_use_cases_content_signing.md) The unifying thesis: once a person signs every piece of content they publish, unsigned content is fake by default.
