Technical Standard for Zero-Knowledge, Privacy-Preserving Application Design.
SecureX is an open, consensus-driven security standard designed to govern how modern client-server applications handle, store, and transmit user-generated data. By implementing the SecureX specifications, software developers and organizations commit to absolute data isolation, zero-knowledge storage architecture, and the complete elimination of third-party user tracking.
Products complying with this specification are authorized to claim SecureX Compliance and display the official validation badge.
All user-generated data, credentials, and sensitive parameters must undergo cryptographic encryption on the client device prior to transport or remote storage.
- Encryption-at-rest must utilize AES-256-GCM (Advanced Encryption Standard in Galois/Counter Mode).
- Cryptographic key derivation from user credentials must be handled via Argon2id.
- The server-side infrastructure must have no access to raw plaintext keys, ensuring a zero-knowledge architecture where data remains unreadable even in the event of a full server infrastructure compromise.
The backend infrastructure must enforce strict boundary isolation between distinct user sessions and datasets at both the logical and database levels.
- Every database query, API transaction, and file system read operation must execute a server-side authentication check using a cryptographically signed token (e.g., JSON Web Token).
- Access control must enforce the matching condition:
request.auth.uid === resource.owner.uid. - Cross-tenant data leakage or unauthorized horizontal privilege escalation must be prevented by design.
Rule 3: Elimination of Third-Party Tracking (No Hidden Eyes)
Applications must operate without any third-party analytics SDKs, advertising pixels, or persistent cross-site tracking systems.
- The embedding of external surveillance frameworks (such as Google Analytics or Meta Pixel) is strictly prohibited.
- Fingerprinting techniques, heuristic behavioral analysis, and unauthorized user interaction logging must be blocked at the application engine level.
System administrators, support teams, and application developers must not possess master keys, backdoor access, or administrative override capabilities to decrypt or view user data.
- No "impersonation tokens" or administrative bypass flags may exist within the authentication schema.
- Database administrative access must require multi-factor authentication (MFA) and be restricted purely to operational metadata and system telemetry.
When a user requests account termination, the system must trigger a synchronous, cascade deletion of all associated data.
- All relational rows and document-store objects linked to the user's unique identifier must be permanently pruned using hard
DELETEcommands. - Cached instances, session states, and temporary disk storage must be invalidated across all distributed nodes immediately.
All data in transit over public or untrusted local networks must be encapsulated within encrypted transport protocols.
- Systems must enforce TLS 1.3 or higher, dropping support for depreciated cipher suites and insecure legacy protocols.
- Applications must transmit strictly via HTTPS and secure WebSockets (
wss://), accompanied by enforced HTTP Strict Transport Security (HSTS) headers.
The core cryptographic modules, data-routing pipelines, and authorization middleware must be hosted in public, open-source repositories.
- Development teams must support deterministic and reproducible builds, allowing external auditors to verify that the distributed binaries match the public source code line-by-line.
Users retain absolute sovereignty over their data. Systems must provide a built-in extraction routine that allows users to export their entire digital footprint on demand.
- Export files must be structured in non-proprietary, machine-readable formats such as JSON, CSV, or SQLite.
Automated application crash reporting and system performance diagnostics must be disabled by default.
- Telemetry may only run upon explicit, manual user consent (Opt-In).
- Prior to ingestion, all client-side diagnostic payloads must be scrubbed of IP addresses, hardware identifiers, and personal parameters.
The authentication module must enforce password complexity requirements to mitigate brute-force and dictionary attacks.
- Passwords must meet a minimum length of 12 characters, requiring alphanumeric and special character entropy.
- Integration with secure breach-checking APIs (e.g., Have I Been Pwned k-Anonymity API) must be utilized during credential registration to block compromised passwords.
Decrypted payloads, temporary variables, and cryptographic keys must reside strictly within volatile memory (RAM) and only for the duration of the operational process.
- Buffers and memory spaces containing cryptographic material must be explicitly cleared or overwritten with zero-bytes immediately after execution to prevent cold-boot or memory-dump exploits.
Every subsystem, microservice, or internal application process must execute using the minimum set of permissions necessary to complete its task.
- Database connections dedicated to public content delivery must not have read or write permissions to the user authentication database tables.
User authorization and consent policies are non-perpetual.
- Any modification to the data handling schema, architectural framework, or privacy policy must immediately invalidate existing consent states.
- The system must halt further data processing and prompt the user to re-authorize under the updated specification.
