Enterprise Rights Management (ERM)

Unlike traditional perimeter-based security, ERM applies AES-256 encryption directly to the document payload. This cryptographic wrapper remains intact whether the file is at rest in a vector database, in transit to a language model, or cached on an end-user device. The decryption keys are managed by a central policy server, ensuring that even if a document chunk is exfiltrated, it remains cryptographically useless without real-time authorization.

• File-level encryption independent of storage infrastructure
• Persistent protection across retrieval, download, and sharing workflows
• Key rotation support to revoke access retroactively

ERM policies define not just who can access a document, but what they can do with it. Administrators can enforce granular permissions such as disabling copy/paste, preventing screen capture, restricting printing, and setting automatic expiration dates. When a RAG system retrieves a rights-managed document, these controls are evaluated in real-time by the Policy Decision Point (PDP) before the content is injected into the prompt.

• View-only mode with clipboard restrictions
• Time-based expiration for ephemeral access grants
• Print and export limitations to prevent analog exfiltration

A critical differentiator of ERM is the ability to enforce policies even when the consuming device is disconnected from the network. A locally cached license with a configurable lease period allows authorized users to open protected documents offline. The license enforces the same usage restrictions and automatically expires, requiring re-authentication against the policy server to refresh access rights.

• Configurable offline lease duration (hours to days)
• Local policy enforcement without cloud dependency
• Automatic revocation upon lease expiry

ERM systems generate immutable audit logs for every document interaction, including open attempts, permission changes, and access revocations. This telemetry is critical for forensic analysis and regulatory compliance. In a RAG pipeline, this extends to logging which chunks were retrieved, by which identity, and under what policy context—providing a complete chain of custody for data injected into generative AI prompts.

• Tamper-proof logging of all access events
• Identity-attributed retrieval tracking for AI pipelines
• Compliance-ready reports for SOC 2, HIPAA, and ITAR audits

Access rights can be revoked in real-time at the user, document, or policy level. When a revocation command is issued, the central policy server immediately denies new decryption key requests. For sensitive documents already cached locally, a remote wipe command can be pushed to the agent on the device, rendering the encrypted content permanently inaccessible. This is essential for offboarding employees or responding to data spillage incidents.

• Instant key revocation via policy server
• Remote wipe of locally cached protected files
• Bulk revocation by user group or document classification

Modern ERM solutions integrate directly with Policy Enforcement Points (PEPs) in retrieval-augmented generation architectures. Before a document chunk is passed to the language model, the PEP queries the ERM policy server to validate the user's entitlements. This ensures that chunk-level authorization respects the same rights management policies as the source document, preventing sensitive data from leaking through AI-generated responses.

• PEP integration for pre-retrieval authorization checks
• Entitlement propagation from identity providers to ERM policies
• Consistent policy enforcement across human and AI access paths
