What is ZeroH Disclosure?

ZeroH Disclosure is a selective disclosure platform for cloud document storage. It uses BBS+ cryptography to isolate PII before documents are uploaded to Google Drive, Outlook, or SharePoint. Sensitive data stays on your own infrastructure. Cloud providers receive only cryptographically redacted proofs. Role-based disclosure profiles control what each user role can see.

How is BBS+ different from standard document redaction?

Standard redaction replaces sensitive text with "[REDACTED]" or a black bar. BBS+ (Boneh-Boyen-Shacham) signatures create a cryptographic proof that reveals specific fields from a document while mathematically concealing others. Recipients can verify that the fields they see are authentic and unmodified. Standard redaction can be disputed or reversed. BBS+ proofs cannot.

Which data residency jurisdictions are supported?

ZeroH Disclosure ships with pre-built compliance profiles for Qatar PDPL, Malaysia PDPA, EU GDPR, UK GDPR, and CCPA. On-premise processing ensures sensitive data never crosses jurisdictional boundaries before BBS+ isolation is applied. Additional jurisdictions can be configured with custom disclosure rules.

Do my teams need to change how they work?

No. ZeroH Disclosure integrates with your existing tools (Google Drive, Microsoft Outlook, and SharePoint) and operates transparently. When a user saves a document to Google Drive, ZeroH Disclosure processes it on-site, applies the relevant disclosure profile, and syncs the BBS+ redacted version to Drive. From the user's perspective, documents sync as normal.

What types of sensitive information does ZeroH Disclosure classify?

ZeroH Disclosure automatically classifies three categories: PII (personally identifiable information: names, IDs, addresses), SPI (special personal information: health data, religion, biometrics, as defined in data protection law), and SFI (sensitive financial information: account numbers, transaction details, credit information). Classification is continuous. New documents are scanned automatically.

How does ZeroH Disclosure work with ZeroH?

ZeroH Disclosure has a native ZeroH Space integration. Compliance documents processed through ZeroH Disclosure, including contracts, Shariah board papers, and audit evidence, feed directly into ZeroH compliance workflows. The BBS+ proofs generated by ZeroH Disclosure become the selective disclosure artifacts used in Trust Center for regulator and auditor sharing. The three products form an integrated data governance stack.

ZeroH Disclosure is currently in alpha. This page describes the product vision. Features are under active development and not yet generally available.

Deterministic Privacy for Cloud.Your Documents. Your Rules. Zero Compromise.

Fully rule-based regulatory compliance. No AI. No probabilistic outputs. Data never leaves on-premise infrastructure. Every document is version-controlled, stored on Qatar IPFS nodes, and anchored on Hedera before touching any cloud platform.

Deterministic Privacy for Regulated Cloud Workflows

Rule-based. Auditable. Every decision traceable to a specific regulation article.

On-Premise Data Residency

Sensitive documents are stored on-site or on-soil. Original files are kept on Qatar IPFS nodes. Only cryptographically redacted versions are uploaded to cloud providers. Data sovereignty preserved by architecture, not policy.

Selective Disclosure by Role

Same document, different views. An auditor sees financial terms but not client PII. An external party sees only the redacted version. Views are determined automatically by who is signed in. BBS+ enforces the rules cryptographically.

Ali Insights: Deterministic Document Analysis

Regulation-based document analysis. Every suggestion is traceable to a specific regulation article (AAOIFI FAS 4, Qatar PDPPL, QFC DPR). Not AI. Not probabilistic. Fully rule-based with human-in-the-loop control.

Proof Pack

The evidence package that gets cloud approved by your regulator. Every document action produces cryptographically verifiable artifacts: Data Processing Agreement, Privacy Impact Assessment, Data Classification Report, ROPA Entry, AI System Risk Assessment.

Continuous Compliance Monitoring

Documents uploaded or edited directly in the cloud are automatically scanned for unclassified PII. Non-compliant files are quarantined with access revoked. Compliance officers are notified.

Version Control and Anchoring

Every document passes through Draft and Anchored states. Each version is stored on Qatar IPFS nodes and anchored on Hedera with a Verifiable Credential. Full audit trail from creation to cloud distribution.

Why ZeroH Disclosure Instead of Cloud DLP Tools

Cryptographic Isolation, Not Redaction

Traditional DLP tools redact sensitive text with black bars or replace it with "[REDACTED]". ZeroH Disclosure uses BBS+ cryptography to create a mathematically sound selective disclosure proof. Recipients verify what they can see is authentic, not just edited text.

vs. alternatives: Microsoft Purview and Google DLP redact text. BBS+ creates cryptographic proofs. Text redaction can be reversed or disputed. Cryptographic proofs cannot.

On-Premise Residency by Architecture

ZeroH Disclosure processes sensitive data entirely on your infrastructure. Cloud providers receive only BBS+ proofs, never the source documents. Data residency compliance is enforced at the architectural level, not by contract clause or data processing agreement.

vs. alternatives: Cloud-native DLP sends data to cloud provider infrastructure for analysis. ZeroH Disclosure analyzes on-site and sends only cryptographic proofs to the cloud.

Works With Your Existing Cloud Stack

ZeroH Disclosure integrates directly with Google Drive, Microsoft Outlook, SharePoint, and ZeroH Space. Your teams keep working with familiar tools. ZeroH Disclosure operates transparently: documents sync to cloud storage, but only the cryptographically redacted version arrives.

vs. alternatives: Replacing cloud storage creates adoption friction. ZeroH Disclosure sits in front of existing integrations, with no workflow change for end users.
