Medicaid and SNAP Need Different Rules, Not Separate Verification Infrastructure

As states implement HR1, Medicaid and SNAP can share verification infrastructure without sharing eligibility rules, reducing duplicate verification while preserving privacy and user control.

What Is State-Endorsed Digital Identity (SEDI)?

State-Endorsed Digital Identity (SEDI) is a rights-first approach to trusted digital identity, pioneered in Utah and gaining interest across states. In this post, we explain what SEDI is, the rights at its center, and our interpretation of how an endorsement framework can work in practice.
Digital Identity Is Becoming Policy Infrastructure

Digital Identity Is Becoming Policy Infrastructure

Digital identity is becoming core policy infrastructure. Across benefits, financial regulation, privacy, and elections, better verification can strengthen trust while reducing unnecessary data collection and giving people greater control over their information.
Medicaid Work Requirements Are a Verification Infrastructure Challenge

Medicaid Work Requirements Are a Verification Infrastructure Challenge

Medicaid’s new community engagement requirements expose a broader challenge for digital government: how to verify facts across fragmented systems. A better model combines data-first verification with portable, privacy-preserving, standards-based digital evidence.
Recommendations to CMS on Medicaid Verification

Recommendations to CMS on Medicaid Verification

SpruceID submitted comments to CMS on implementing new Medicaid community engagement requirements. Our recommendations focus on maximizing ex parte verification, expanding reliable evidence options, and keeping digital pathways voluntary, interoperable, and privacy-preserving.

What Is Device Binding, and How Does It Keep a Stolen Digital ID From Being Reused?

Device binding is the cryptographic layer that turns a verifiable digital credential from something that can be copied into something that can only be used by its rightful holder.

What Is Public Key Infrastructure and Why Does It Matter for Government Digital Services?

Every time a mobile driver’s license is verified in seconds, it’s PKI doing the invisible work of turning cryptographic keys into trusted digital identity.

Why Signing Keys Are an Important Part of Your Credential Program

A verifiable digital credential program's trustworthiness depends not only on the credentials it issues, but on how the signing keys behind those credentials are protected, managed, and governed throughout their lifecycle.
