Can We Trust What We See? — Assessment

Vendor A embeds a detectable signal in generated image pixels. Vendor B attaches a signed C2PA manifest recording generation and subsequent edits; procurement is using supplied guidance requiring robust, machine-readable marking without prescribing one technology.

Which procurement conclusion is best supported?

• AOnly A qualifies because marking must be embedded within the image pixels.
• BOnly B qualifies because a cryptographic signature is the required marking method.
• CEither approach could qualify, subject to evidence that its implementation meets the criteria.
• DBoth qualify automatically because each uses a recognized origin-signaling technology.

A newsroom receives two files: one has a detectable generation watermark but no edit log, and the other has a validated signed manifest listing a creator and two edits. The editor wants to know what each mechanism contributes.

Which distinctions are justified? Select all that apply.

• The watermark can signal artificial origin without supplying a complete edit history.
• The signed manifest can support verification of recorded creation and editing claims.
• The watermark can substitute for the manifest when verifying the sequence of edits.
• A validated manifest establishes that every earlier action was captured in its history.

A technical review finds a pixel-level generation signal, a signed creation-and-edit manifest, a visible 'AI image' caption, and an unsigned author field. Reviewers must distinguish technical evidence from labels and unverified metadata.

Match each finding to the strongest interpretation it supports.

A procurement reviewer rejects a proposed marking method solely because it is not C2PA. The supplied European Commission guidance describes criteria for robust, machine-readable marking without mandating a particular standard.

Assertion: Rejecting the proposal solely because it is not C2PA is justified. Reason: A method-neutral requirement evaluates relevant capabilities rather than requiring one named technical standard.

• ABoth A and R are true and R is the correct explanation of A
• BBoth A and R are true but R is NOT the correct explanation of A
• CA is true but R is false
• DA is false but R is true

A vendor supplies only a validated embedded generation signal. Its marketing team wants the product specification to promise a cryptographically verifiable record of every edit.

The evidence supports origin detection, but not the promised creation-and-edit ___ .

A team compares watermark-only and signed-provenance-only products. Both vendors claim that adopting their technology removes the need for further technical evaluation.

Which procurement requirements remain appropriate? Select all that apply.

• Require evidence that machines can reliably extract and interpret the marking.
• Accept successful detection on vendor originals as sufficient robustness evidence.
• Test relevant distribution transformations rather than relying on the method's name.
• Examine detector or validator failure modes and operational dependencies.

An editor exports a generated image through software that removes its signed manifest. A compatible detector still recognizes its embedded watermark.

What should the verification report say?

• AAn origin signal remains detectable, but the distributed file lacks the previous signed history.
• BThe surviving watermark is sufficient to report the previous signed history as verified.
• CThe missing manifest invalidates the detector's otherwise successful watermark result.
• DThe retained watermark establishes that no meaningful edits occurred during export.

A procurement committee hears four claims: 'C2PA is mandatory,' 'signed means complete,' 'embedded means indestructible,' and 'machine-readable means publicly disclosed.' It needs a targeted correction for each.

Match each claim to its most direct correction.

Six source files each have detectable watermarks and accessible signed manifests. After platform upload, downloaded copies retain detectable watermarks but no longer expose the manifests through the same inspection tools.

Which conclusions are supported? Select all that apply.

• The missing manifests indicate that the platform rejected the source signatures as invalid.
• The platform path may have removed or failed to preserve provenance metadata.
• Watermark detectability and manifest availability behaved differently in this test.
• The retained watermarks show that the full origin record survived in an embedded form.

A team has six media files and wants to determine whether compression, cropping, or upload affects origin evidence. It can preserve originals and create separate transformed copies.

Which test design best supports interpretable comparisons?

• AApply all transformations in sequence, then compare the final copies with originals.
• BPreserve baselines and test separate transformation copies, recording both evidence channels.
• CGroup samples by visual realism, then test the least realistic member of each group.
• DTest only files whose provenance viewer already identifies them as synthetic.

An analyst will test six originals using compression, cropping, and platform upload. The lab requires immutable originals, baseline measurements before transformations, and a final sample-by-sample comparison.

Arrange the lab stages in the required order.

In a six-file lab, sample A loses watermark detection after heavy compression, B loses its manifest after upload, C looks photographic despite known generation, and D produces different detector outputs across versions. Each result needs a distinct interpretation.

Match each observation to the most appropriate limitation to record.

A known watermarked original tests positive, but its compressed derivative tests negative. The analyst can rule out a file mix-up and has retained the original result.

Relative to the derivative's known marked origin, the negative detector result is a ___, not evidence that it became a camera recording.

A lab dashboard currently reports only 'four of six files passed verification.' The engineering lead wants results that another team can reproduce and interpret after compression, cropping, and upload.

Which additions materially improve the record? Select all that apply.

• A row linking each sample's original and transformed-copy identifiers.
• Separate fields for detector outcome and provenance-metadata availability.
• A single authenticity percentage averaging metadata and detector results.
• Transformation settings, tool versions, and explicit errors or inconclusive outcomes.

All six test images remain visually unchanged to reviewers after upload. Metadata inspection shows that five manifests disappeared, and watermark detection fails on two downloaded files.

Which summary best represents the test?

• AThe upload preserved origin evidence because reviewers saw no visual changes.
• BThe two detection failures establish that upload removed the watermarks, rather than weakening them.
• CThe five missing manifests indicate signature validation failures rather than metadata loss.
• DVisual similarity concealed losses in machine-readable evidence on this upload path.

A benchmark uses six known-generated images, including an exported version whose watermark is no longer detectable after cropping. The report retains the original generation records.

Assertion: The cropped image's negative detector result should not override its documented generated origin. Reason: Cropping can remove or weaken evidence needed by a watermark detector.

• ABoth A and R are true and R is the correct explanation of A
• BBoth A and R are true but R is NOT the correct explanation of A
• CA is true but R is false
• DA is false but R is true

A clearly watermarked AI illustration accurately reproduces figures from an audited transport report. A genuine camera photograph is captioned as showing today's protest, but independent archives place it five years earlier.

Which assessment correctly separates origin from accuracy?

• AThe audited figures validate the illustration, while camera origin makes the photograph's current-event claim credible.
• BThe illustration may convey accurate facts, while the photograph's current-event claim is misleading.
• CBoth are factually unreliable because neither is an untouched recording of today's events.
• DBoth are reliable because one has an origin marker and the other is genuine photography.

An analyst reviews five items: a marked generated chart, an unmarked viral clip, a signed camera image, a signed generated reconstruction, and a repost with no metadata. Each is accompanied by a factual claim.

Which assessment rules are sound? Select all that apply.

• Require a camera-derived version of the chart before accepting its figures as factual.
• Treat the unmarked clip's origin as unresolved unless other evidence establishes it.
• Evaluate the signed reconstruction's factual claims separately from its recorded origin.
• Seek corroboration for the camera image's caption even if its provenance validates.

A signed camera photograph has a validated creation record. A publisher uses it to claim that a particular factory caused a nearby illness outbreak.

Assertion: The photograph's validated provenance establishes the publisher's causal claim. Reason: Cryptographic provenance can verify integrity and attribution of recorded creation-history claims.

• ABoth A and R are true and R is the correct explanation of A
• BBoth A and R are true but R is NOT the correct explanation of A
• CA is true but R is false
• DA is false but R is true

An editor reviews five examples: a marked evacuation simulation, an unmarked explosion clip, a signed camera photograph, a signed generated portrait, and an old authentic flood video labeled as today's news.

Match each example to the most defensible interpretation.

A generated medical illustration has a valid origin marker. A reviewer approves all its anatomical claims solely because the marker validates.

The reviewer has confused production-origin evidence with evidence of ___ .

A viral clip has no detectable watermark and no accessible provenance manifest. Its caption alleges election interference, and the original uploader has not been identified.

Which statements are warranted? Select all that apply.

• The caption's claim still requires evidence independent of marker inspection.
• The allegation merits higher confidence because both origin checks returned negative results.
• The missing markers are compatible with several different production histories.
• The absence of both mechanisms indicates that the creator deliberately concealed the clip's origin.

A supplier's signed provenance record validates for an image claiming that a bridge has collapsed. The signature belongs to the supplier, but no independent reporting confirms a collapse.

What is the most appropriate publication assessment?

• APublish the collapse as confirmed because a validated signer accepts responsibility.
• BTreat the signature as failed verification because the event lacks independent confirmation.
• CTreat the signature as equivalent to independent eyewitness corroboration.
• DRecord the provenance result but leave the collapse claim unconfirmed pending corroboration.

A product team proposes replacing its fact-checking queue with origin checks. It would approve signed camera images, reject marked generated images, and send only unmarked files for review.

Which objections identify substantive flaws? Select all that apply.

• Signed camera images can still be staged or attached to misleading claims.
• Marked generated images can contain accurate, independently verifiable information.
• A validated camera signature should narrow review to captions, excluding possible scene staging.
• Unmarked files are not the only files whose factual claims need examination.

A workshop investigates a purported train-crash image and a mayor's alleged resignation video. Its reporting template requires metadata inspection, reverse lookup, source-provenance verification, and contextual evaluation in that sequence, followed by a qualified assessment.

Arrange the work packages to follow this workshop protocol for both items.

An unfamiliar storm image has no accessible metadata, and reverse lookup finds no match. The uploader says it was captured locally this morning, but their identity and the location have not been checked.

What is the best next assessment step?

• AVerify the uploader's source trail and examine location, timing, and independent weather evidence.
• BClassify it as newly captured because reverse lookup found no earlier publication.
• CRepeat the same two checks with more tools before investigating the uploader or local conditions.
• DPublish it as provisionally authenticated because two technical checks found no contradiction.

A team has verified the metadata and reverse-search results for an alleged factory-fire image and an executive audio clip. Both were supplied by newly created accounts claiming to represent established news organizations.

Which actions address the remaining source and context checks? Select all that apply.

• Verify the accounts by matching their profile details to the organizations' public branding.
• Contact the organizations through independently located official channels.
• Compare the image and audio claims with independent event and timing evidence.
• Accept matching organization names in metadata as verification of the supplying accounts.

For a tunnel-collapse photo and a purported ministerial announcement, investigators validate a manifest, find an older image match, confirm an uploader through official contact, and compare the announcement with the full speech. They must place each result under the right checklist step.

Match each investigative action to its primary checklist step.

A video genuinely records a director saying, 'We will close the plant,' but the full speech continues, 'only if the safety tests fail.' Metadata and source checks validate the recording.

Before assessing the shortened clip's claim, the missing verification dimension is ___ .

Investigators complete all four checklist steps for an unfamiliar rally photo and a leaked audio clip. The photo's date is corroborated, but its caption overstates attendance; the audio's uploader remains unidentified and no original file is available.

Which reporting choices are appropriate? Select all that apply.

• State separately which photo claims are supported and which remain unsupported.
• List the unavailable audio original and unresolved uploader identity as limitations.
• Label both items authenticated while placing remaining uncertainties in a separate limitations section.
• Record the evidence, tool outputs, and scope of conclusions for each item.

Reverse lookup finds the same earthquake image on twenty sites posted within ten minutes. Metadata is absent, and all sites cite one anonymous social account.

How should the investigator treat these twenty appearances?

• AAs corroboration from multiple publishers, even though their attribution leads to one account.
• BAs corroboration of the earthquake's timing because the publication timestamps are clustered.
• CAs a likely shared-source chain that still requires source and context verification.
• DAs verification of the earliest site's authenticity because it appears first.

A team completes all four verification steps for a station-evacuation video but cannot establish its recording date. Its report says that the claimed date remains unresolved.

Assertion: The report is appropriately qualified rather than a failed verification effort. Reason: Provenance metadata may be stripped during platform uploads.

• ABoth A and R are true and R is the correct explanation of A
• BBoth A and R are true but R is NOT the correct explanation of A
• CA is true but R is false
• DA is false but R is true

A vendor markets a generative-video system under its own brand. An advertising agency uses that system to publish a realistic fabricated endorsement by a real athlete; assume the relevant Article 50 duties apply and no exception is available.

Which allocation of responsibilities is most appropriate?

• AThe vendor handles marking; the agency has no further duty if that mark remains embedded.
• BThe agency handles disclosure; its disclosure removes the vendor's marking duty.
• CThe agency takes over both duties because it controls the final published video.
• DThe vendor addresses machine-readable marking; the agency clearly discloses the deepfake.

A provider offers spelling correction, exposure correction, scene replacement, and face-swapped interviews. Counsel asks engineering to identify functions potentially within the standard-assistive-editing exception rather than treating all editing alike.

Which functions are the strongest candidates, assuming they do not substantially alter the input or its semantics? Select all that apply.

• Correcting spelling in a user-supplied paragraph without changing its meaning.
• Replacing an empty street with a plausible crowd while preserving the street's layout.
• Adjusting exposure in an existing photograph without changing depicted content.
• Replacing an interviewee's face for anonymization while preserving their spoken statement.

Four organizations need an Article 50 triage: a branded image-generator vendor, a company publishing an unexceptional deepfake address, a publisher releasing unreviewed AI-generated public-interest text, and an editor publishing such text after substantive review with editorial responsibility. Assume applicability and no other exception.

Match each organization to the most relevant obligation or exception assessment.

A publisher releases AI-generated text about a public-health policy. A named editor substantively checks and revises it, but the workflow also needs an identified person or entity accountable for publication.

For the relevant text-disclosure exception, the plan must address human review or editorial control and ___ responsibility for publication.

A news app publishes AI-generated election explainers after an employee checks formatting only. No person or entity has accepted editorial responsibility, and the team wants to rely on the human-review exception.

Which conclusion is most defensible?

• AThe exception applies because any human interaction before publication counts as review.
• BThe stated workflow does not establish the exception; plan disclosure unless its conditions are met.
• CThe exception applies because election explainers are text rather than audiovisual media.
• DThe provider's embedded origin mark permits the publisher to treat the text as already disclosed.

A communications firm uses an external generator to publish a realistic synthetic CEO apology and unreviewed AI-generated commentary on a public referendum. The vendor has embedded machine-readable output marks; assume no disclosure exception applies.

Which conclusions follow for the communications firm? Select all that apply.

• Its use of an external system makes it a deployer in these scenarios.
• The synthetic CEO apology calls for clear deepfake disclosure.
• The unreviewed public-interest commentary calls for applicable text disclosure.
• The vendor's embedded marks satisfy all audience-facing disclosure duties.

A generative-image provider proposes making machine-readable marking an optional customer setting. Its justification is that publishers, rather than system suppliers, decide how content will be used.

Assertion: Applicable provider-side marking duties are not generally removed by a customer's publication choices. Reason: Article 50 addresses provider-side machine-readable marking separately from relevant deployer-side disclosure.

• ABoth A and R are true and R is the correct explanation of A
• BBoth A and R are true but R is NOT the correct explanation of A
• CA is true but R is false
• DA is false but R is true

A software company both supplies its branded generator and uses it to publish a realistic fabricated interview. Its publication team argues that the organization must be either a provider or a deployer, but cannot be both.

Which corrections are appropriate? Select all that apply.

• Provider status automatically absorbs any deployer duties for the same organization.
• The organization can occupy different roles through its supply and use activities.
• The fabricated interview needs a separate assessment of public-disclosure duties.
• Internal use preserves provider-only status because no external customer operates the system.

A team plans to publish a synthetic candidate interview on 20 November 2026. Its supplied briefing, dated 1 July 2026, lists 2 August 2026 as Article 50's general application date, identifies no applicable transition for this project, and requires checking subsequent official updates.

Which scheduling decision is best supported by this briefing?

• APlan for applicable duties at publication and verify whether later official guidance changes the analysis.
• BAssume all AI Act transparency duties are deferred until the end of 2026.
• CTreat content generated before 2 August as exempt even if first published in November.
• DDefer publication controls until the generator vendor confirms completion of its own compliance rollout.

A studio will publish a realistic satirical video of a public official through a platform that requires visible synthetic-media labels. The producer claims that artistic satire removes every marking and disclosure requirement.

Which elements belong in the publication plan? Select all that apply.

• Treat the satire description as a blanket exemption for the studio and its generator vendor.
• Assess the qualified artistic or satirical disclosure treatment rather than assuming no notice is needed.
• Check provider-side marking separately and satisfy the platform's applicable labeling rules.
• Specify an appropriate disclosure that does not unnecessarily hamper enjoyment of the work.

A November 2026 synthetic-media release uses a review workflow with dependencies: classification must precede exception analysis; legal timing and exceptions must be resolved before platform checks; final notices and educational caveats are approved last. The dated guidance pack requires checking whether any transition actually covers the project.

Arrange the approval packages according to this workflow.

A brand publishes a realistic synthetic testimonial. Its production file has a valid invisible origin mark, but viewers see no notice and no disclosure exception applies.

The publication plan still needs clear public ___ rather than relying solely on the hidden mark.

A publication plan contains five unresolved claims: the vendor owns all duties, satire needs no notice, a police-themed campaign qualifies for a law-enforcement exception, an internal November migration date delays the law, and legal compliance guarantees platform acceptance.

Match each claim to the required corrective action.

A private security consultancy produces a synthetic suspect appeal for a police client. The project manager claims a law-enforcement exception based only on the client's identity; the file contains no documented legal authorization or scope analysis.

What should the publication plan require?

• AAccept the exception because a police client commissioned the content.
• BApply the exception whenever the video could assist a criminal investigation.
• CVerify the relevant legal authorization and conditions before relying on the exception.
• DRely on the police client's approval email without checking the applicable legal basis.

A release pack dated 10 November 2026 contains an old legal summary, a platform notice offering a labeling rollout grace period until 1 December, and an internal migration target of 25 November. No document establishes that either later date postpones an applicable Article 50 duty.

Which planning decisions are justified? Select all that apply.

• Verify current official requirements and any project-specific transition before approving publication.
• Keep the platform grace period distinct from the legal application analysis.
• Align legal disclosure readiness with the platform's 1 December grace period for this distribution channel.
• Approve publication on 25 November because completing the internal migration demonstrates transition compliance.

A workshop team submits a synthetic-media publication plan with role assignments, qualified exception analysis, dated implementation checks through November 2026, and platform requirements. A manager wants to circulate it as definitive professional clearance.

The cover note should state that this is an educational assessment, not ___ .
