VETO: Towards Protecting Images From Frontier AI Editing

A subtle image cloak that disrupts how modern unified editors attend to a protected reference image.

Reference attention shield
VETO adds a subtle cloak to a source image, diffusing attention between reference and canvas tokens so faithful editing breaks down.

01 / Key message

Modern editors repeatedly read a reference image through joint attention. VETO protects the image by diffusing that attention before a faithful edit can form.

02 / Method

How it works

01

Read the source

Track where canvas tokens retrieve information from protected reference-image tokens.

02

Diffuse attention

Optimize a subtle image perturbation that maximizes entropy across the reference-canvas attention blocks.

03

Break faithful editing

The editor can no longer preserve the source reliably, while the protected image remains visually close to the original.

03 / Abstract

Abstract

Frontier image editors such as FLUX.2 can move identities and objects into entirely new scenes, extending misuse beyond predictable localized edits. Existing anti-edit defenses target the encoder bottleneck used by legacy diffusion pipelines, but unified editors repeatedly access source-image tokens through joint attention. VETO instead optimizes a subtle per-image cloak that maximizes the entropy of canvas-to-reference and reference-to-canvas attention, disrupting source information as it flows into the generated output. The accompanying VetoBench evaluates both conventional closed-frame edits and open-frame recontextualization across general, defamatory, and graphic scenarios.

What this adds

  1. 01

    Attention-level protection

    Targets the joint-attention mechanism used by native DiT editors instead of attacking a legacy encoder bottleneck.

  2. 02

    Stronger protection-fidelity trade-off

    Consistently leaves fewer successful edits while preserving more of the protected image than prior cloaking methods.

  3. 03

    VetoBench

    Adds 300 curated cases spanning closed-frame edits and open-frame recontextualization across general, defamatory, and graphic scenarios.

05 / VetoBench

Protection against open-frame misuse

Twelve examples from the 300-case benchmark: two closed-frame and two open-frame edits across each evaluation category.

VETO Objective and Benchmark

Explore the mechanism VETO targets, then inspect how VetoBench divides modern editing misuse into six balanced settings.

VETO Objective

From localized attention to a diffuse field

This canvas-to-source head initially attends to the cat's face. VETO raises its entropy into a broad but imperfect field, weakening the localized correspondence needed for a faithful edit.
