Define acceptable use
Associate protected data with rules covering authorised purpose, identity, device, environment, time or other approved conditions.
PastWipe addresses the stage conventional cybersecurity cannot guarantee: what happens after protected data is copied, exposed or exfiltrated. It combines policy-aware control, cryptographic validation, identity and device context, and evidence records to reduce the usable value of data outside approved conditions.
PastWipe complements existing identity, endpoint, network, DLP, monitoring and incident-response systems. It does not replace them.
Associate protected data with rules covering authorised purpose, identity, device, environment, time or other approved conditions.
Evaluate whether current conditions still satisfy the policy before protected content is released, rendered or accepted.
Support review, audit and incident analysis with evidence showing what was requested, evaluated, permitted, denied or degraded.
Firewalls, EDR, IAM, DLP, SIEM and incident response are essential. But once a usable copy leaves the protected environment, the organisation can lose practical control over how long it remains useful, where it is used and who can rely on it. PastWipe is designed for that unresolved stage.
The objective is not to promise that every breach can be stopped. It is to reduce the consequences when prevention, detection or human behaviour fails.
The implementation can vary by sector and system. The core principle remains consistent: protected data should not be treated as permanently trusted merely because access was valid at the moment it was first obtained.
Apply PastWipe to information and workflows where post-breach misuse would create material financial, operational, legal or public harm.
Define the conditions under which the data may be opened, validated, rendered, transferred or relied upon.
Use available identity, device, environment, time, purpose and attestation signals to test whether the use remains legitimate.
Permit, deny, restrict or degrade the result, then create evidence suitable for operational review and investigation.
PastWipe is the deployable post-breach control approach. RepSec is the optional protocol framework intended to help different systems express policy, validation, evidence and non-reusability in a more interoperable way. PastWipe does not depend on universal RepSec adoption.
PastWipe can be integrated into selected applications, data flows and enterprise controls without waiting for a new internet-wide standard.
RepSec describes a direction for consistent policy, validation and evidence exchange across participating systems. RepSec-Q extends that direction toward post-quantum resilience.
Credible security requires clear boundaries. PastWipe reduces risk in supported, policy-aware workflows; it does not claim to remove every form of copying, disclosure or misuse.
PastWipe is not a substitute for access control, endpoint protection, network security, DLP, monitoring, backup or incident response.
An authorised viewer may still photograph a screen, retype content or create another physical representation. No software can eliminate that risk completely.
The strongest control applies before or during authorised use. Once data is exported into an unsupported, unrestricted format, enforcement may be reduced or lost.
Results depend on integration depth, supported applications, connectivity, device trust, identity signals and how much control the organisation retains over the workflow.
The practical objective: materially reduce the value, reliability and legitimate usability of protected data after trust is lost—without pretending that software can defeat every human or physical copying method.
PastWipe is most relevant where the value of copied data remains high long after the breach itself: regulated information, financial records, citizen data, intellectual property, operational documentation and sensitive evidence.
Apply policy-aware controls to selected internal, customer, contractual or intellectual-property workflows where persistent misuse would be material.
Support stronger control around sensitive records, regulated processes, evidentiary confidence and post-breach exposure.
Address citizen data, sovereignty-sensitive information and higher-assurance workflows where unauthorised reuse may create lasting public harm.
Provide clearer technical evidence and a more measurable post-breach control story for security leaders, incident responders, legal teams, underwriters and technology partners.
The useful evaluation is whether PastWipe can reduce exposure for a defined data class, within a defined workflow, under measurable operating conditions.
Start with high-value information rather than attempting to protect every file in the same way.
Assess identity, device, application, environment, time, connectivity and attestation requirements.
Define success before deployment and test against real attack, misuse and operational scenarios.

A concise explanation of where PastWipe fits, what RepSec means and where the technical boundaries remain.
No. Those controls remain essential. PastWipe adds a separate layer aimed at maintaining leverage after protected data has already moved beyond the original trust boundary.
No universal claim is credible. The achievable outcome depends on the protected format, integration, workflow, policy, available context signals and whether an unrestricted plaintext copy already exists. The objective is measurable reduction of utility and legitimate acceptance under unsupported conditions.
No. PastWipe can operate without RepSec. RepSec is the optional protocol direction for more consistent interoperability between participating systems.
Offline operation may be possible for defined periods and policies, but it changes the trust model. Local validation, cached authority, device integrity, expiry, reconciliation and failure behaviour must be designed and tested for the specific environment.
No. Encryption protects confidentiality when keys and access remain controlled. PastWipe addresses the additional question of whether data should still be usable when the surrounding conditions, identity, device or purpose are no longer trusted.
Define the data, threat, operating conditions and measurable outcome. PastWipe can then be assessed as an additional control layer—without replacing the security systems already in place and without relying on unrealistic claims.
