vyplnn

Vyplnn is a fictional term used in this article to describe a hypothetical protocol for automated, privacy-respecting form filling across web services. The concept envisions a lightweight standard that allows a user’s verified data to be securely populated into online forms with explicit consent, reducing manual data entry while preserving control over which data is shared and with whom.

Origins and naming: The term vyplnn is inspired by the notion of filling in forms; in this article it is treated as a coined concept rather than a real-world standard. The concept is used here for illustrative purposes in discussions of data privacy, identity, and interoperability.

Overview and design: Vyplnn proposes a modular architecture comprising: 1) a data wallet that stores verifiable claims, 2) a consent and policy layer that governs which attributes may be shared, and 3) a form-translation layer that maps form schemas to compatible data sets. It emphasizes user consent, minimal data disclosure (data minimization), and cryptographic proofs to validate data without revealing raw values when possible.

Applications and status: In speculative use cases, vyplnn could streamline account creation, checkout flows, and government forms, while enabling cross-domain reuse of data. Prototypes exist in educational settings and toy implementations; no official standard has been adopted, and the concept remains primarily theoretical.
