A zero-knowledge identity, credential, and verifiable data platform for SIM registration and mobile identity.

Telecommunications & SIM Registration

Challenges: Telecom operators must perform SIM registration and subscriber identity verification at massive scale to combat fraud, abuse, and security threats. Many jurisdictions legally require KYC for mobile SIMs and mobile money, while regulators demand strong auditability and data protection. At the same time, telcos are expanding into digital services such as mobile wallets, OTT apps, and super-apps where user identity and account linking depend on querying large subscriber and risk databases correctly and securely. They need seamless, high-assurance onboarding and login for millions of users, without building new data honeypots or leaking sensitive records.

ZAKAPI for Telecom: Zakapi provides specialized modules for SIM Registration, Mobile ID, and Telco KYC that streamline compliance while improving customer experience. Under the hood, SIM-KYC and subscriber checks are expressed as SQL-style policies over your subscriber, risk, and entitlement databases, with each decision backed by a non-interactive zero-knowledge proof that the query was executed correctly on the right, up-to-date dataset, without revealing underlying rows.

Instant SIM Registration

Instead of photocopying IDs in-store or uploading documents for a new SIM, customers verify identity with a Zakapi proof. At purchase or eSIM activation, the operator backend triggers Zakapi to request a proof that a valid government ID exists and age is at or above the required threshold from the customer wallet and, where relevant, an authoritative registry. Zakapi turns this into an authenticated SQL-style check over a committed identity database, for example national eID, MNO KYC records, or a partner registry, and returns a non-interactive proof that the conditions hold. The system logs the proof and decision, not copies of passports or IDs. This eliminates manual entry errors, shrinks stored PII, and gives regulators cryptographic evidence that the correct checks were performed.

eKYC for Mobile Services

As operators launch mobile money, micro-lending, and value-added services, they must reuse or extend SIM KYC without repeatedly collecting documents. Zakapi lets you express eKYC rules as SQL-style policies over customer and transaction datasets, for example "KYC completed within last 12 months and not on sanctions list and risk_score is below threshold". When a prepaid user activates a payments app, Zakapi evaluates these policies on committed KYC and screening databases and returns a reusable proof of compliance, so the user does not need to resubmit documents or revisit a store.

Mobile ID and Authentication

Leverage SIM and device as strong factors, combined with Zakapi verifiable credentials and proofs. On a partner website or app, users choose "Login with Mobile ID". The relying party receives a non-interactive proof that:

• This device or SIM is bound to a specific subscriber record, and
• The subscriber identity credential satisfies the required policy, for example "subscriber verified to LoA high".

The underlying checks, such as SIM status, subscriber record consistency, and ID validity, are implemented as SQL-style queries over your subscriber databases and policy tables, with proofs that the queries ran correctly against the committed snapshot. This reduces dependence on SMS OTPs, mitigates SIM-swap risk, and turns login into a simple, high-assurance interaction.

Fraud Prevention and SIM Swap Protection

Zakapi can bind a verifiable credential to a device or eSIM profile that expresses policies such as "this MSISDN is active, not blacklisted, and bound to identity X". When a SIM swap or remote eSIM provisioning is requested, the system can require a fresh Zakapi proof that evaluates fraud and risk rules over internal databases and reveals only a yes or no result. Attackers who have stolen passwords or screenshots cannot forge the underlying non-interactive proof or fake the committed database state, which reduces identity fraud and abusive SIM churn.

Regulatory Alignment and Data Sovereignty

Telecom regulators expect strong evidence that every SIM, mobile money account, or high-risk service activation followed KYC rules and local data laws. Zakapi maintains cryptographically verifiable logs of each verification event, capturing which SQL-style policy was applied, which committed database version was referenced, and the resulting non-interactive proof. Operators can deploy Zakapi in national data centers, keep keys and commitment logs under local jurisdiction, and present regulators with proof-based audit trails that show checks were executed correctly, without replaying queries on live subscriber data or exposing underlying tables. Cross-border scenarios, for example roaming eSIM profiles, can leverage compatible eID and trust frameworks so that a telco in Country A accepts proofs rooted in identity systems from Country B while still preserving local compliance and privacy.

Value-Added Identity and Data Services

Telcos can also become identity and verification providers. Using Zakapi, operators issue "telco-verified" credentials, backed by their own KYC and network data, that other services such as banks, wallets, and government portals can rely on. Each relying party receives non-interactive proofs that its specific SQL-style policy over the telco committed data, for example "MSISDN active for more than 6 months and KYC completed and not high-risk", evaluates to true, without learning the raw subscriber record. This unlocks new revenue streams around mobile ID and fraud-screening services, grounded in transparent, auditable cryptography rather than opaque scoring APIs.

Value Proposition for Telcos

Comply with SIM registration laws and mobile-money KYC efficiently while gaining customer trust by never over-collecting or over-sharing data. Reduce the operational and legal burden of storing ID documents and large amounts of PII. Cut fraud and SIM-swap abuse by tying activation and high-risk actions to proofs over your real subscriber and risk databases, not screenshots and manual checks. Position your organization as a core trust anchor in the digital ecosystem, offering Mobile ID and proof-based verification services built on the same non-interactive zero-knowledge techniques that enable verifiable SQL in modern systems, while keeping sovereignty and control over your infrastructure.
