QDocSE

Lifecycle Data Self-Protection for Servers, Databases, and Critical Workloads

QDocSE is BicDroid’s integrated data-protection product combining two cooperating cryptographic mechanisms — the FS Cryptographic Module and BCEI-CERI — with a centralized, hardware-rooted control plane, the QDocSE Server. The result is a property no encryption-only or access-control-only product can match: data that stays protected even when the operating system, the application, or the privileged user account has been compromised.

How it works
Tap to enlargeQDocSE architecture — three concurrent access types, the protected machine with FS Cryptographic Module and BCEI-CERI, and the QDocSE Server with certified HSM.
Three concurrent access types resolve at the kernel FS module on the protected machine; a hardware-rooted QDocSE Server governs keys, policy, and audit.

QDocSE assumes the attacker is already inside. Its guarantees begin where conventional defenses end.

Architecture

On every protected machine, the FS Cryptographic Module and BCEI-CERI cooperate to enforce data self-protection at the kernel level. Across the deployment, the QDocSE Server provides centralized hardware-rooted control through a certified Hardware Security Module.

Module 1

FS Cryptographic Module

A kernel-resident engine implementing source encryption at the file-system layer, with anti-tampering and anti-uninstall properties. Supports AES, RSA, ECC and the SM2/SM3/SM4 national standards; a unique key per file; typically under 5% overhead on database servers.

Module 2

BCEI-CERI

BCEI is a cryptographically verified identity for every running program — a hash composition of its binary, dependencies, configuration, and runtime. CERI uses it to govern three concurrent access types: plaintext for authorized apps, ciphertext-only for backup/replication/audit tools, and full denial for everything else.

Control plane

QDocSE Server

A hardware-rooted control plane the customer owns: HSM-anchored key generation and storage, centralized policy, multi-administrator separation of duties, real-time audit-log aggregation, and mutually authenticated channels to every protected machine.

What QDocSE protects against

QDocSE’s defense does not depend on detecting attacks. It depends on the cryptographic invariant that plaintext access requires an identity the attacker does not possess.

AI-driven zero-day exploitationData stays encrypted regardless of the vulnerability used — signature-, detection-, and novelty-independent.
OS & kernel-privilege escalationRoot does not, by itself, grant usable plaintext access.
Supply-chain implantsDeviation from the canonical authorized form fails BCEI verification.
Lateral movementA pivot reaches protected machines, but the data on them remains ciphertext.
Insider exfiltrationFiles copied at the disk level are ciphertext, useless outside the authorized context.
RansomwareA payload outside the authorized context cannot read the plaintext it needs to encrypt.

Compliance & defensibility

QDocSE makes regulatory defensibility a structural property: cryptographic protection by default supports the technical-measures expectations of regimes such as PIPEDA, PHIPA, and GDPR; cryptographically anchored audit trails let auditors verify what was accessed, by which identity, when, and under which policy; and data residency can be enforced by execution context rather than operational policy alone.

Deployment

  • No application source-code changes — the module operates beneath the application layer; existing databases and middleware see data through their normal interfaces.
  • Coexistence during transition — a hybrid mode lets protected and unprotected data coexist for incremental migration.
  • Automatic learning of authorized programs — a learning mode derives BCEI authorization rules from observed legitimate access.

QDocSE has been deployed across government, healthcare, airport operations, finance, and electric-power infrastructure, where its cryptographic components have been formally evaluated and certified by national cryptographic authorities.

The BicDroid family

Each product enforces its guarantee without depending on perimeter trust, host integrity, or the correct behaviour of the software it protects. Deploy one, or combine them for the complete cryptographic lifecycle.

When root itself is compromised, what still holds?

QDocSE protects what every other layer can no longer be trusted to protect: the data itself.
