Deepfakes and Digital Evidence: Why Verification Matters Before You Rely on What You See

DLI Investigative Brief

Digital information appears in nearly every modern investigation.

A photograph may arrive by text message. A video may be downloaded from social media. An audio recording may be attached to an email. A screenshot may become important in a lawsuit, insurance claim, employment dispute, business investigation, or confidential private matter.

At the same time, artificial intelligence has made convincing synthetic images, video, audio, identification documents, social profiles, and written communications increasingly accessible.

The practical question is no longer simply whether digital information can be found. It is whether that information can be verified, placed in context, and documented responsibly before important decisions are based on it.

Convincing does not necessarily mean verified

The FBI reports that scammers are using fake social profiles, cloned voices, fraudulent identification documents, and believable videos depicting public figures or loved ones. The FBI’s Internet Crime Complaint Center recorded more than 22,000 complaints involving artificial intelligence in its latest reporting, representing nearly $893 million in reported losses.

These developments do not mean every unusual photograph, recording, or message is fraudulent. They do mean appearance alone should not automatically be treated as proof.

A digital item may be relevant without necessarily being reliable.

Why provenance matters

One important concept in digital investigations is provenance—where information originated and what may have happened to it afterward.

Depending on the material and circumstances, useful questions may include:

Where did the original file come from?
Is the available file an original or a copy?
Was it forwarded, edited, downloaded, or recompressed?
Is metadata available?
Can the date, location, sender, or source be independently corroborated?
Are there witnesses, records, or other facts supporting what the material appears to show?

The National Institute of Standards and Technology identifies metadata, digital signatures, watermarking, content credentials, and other provenance techniques as potentially useful tools. NIST also cautions that watermarks and metadata can be removed or manipulated and that synthetic-content detection continues to present technical limitations.

No single test resolves every authenticity question.

Why attorneys should pay attention

Authentication is already a familiar evidentiary requirement.

Louisiana Code of Evidence Article 901 requires evidence sufficient to support a finding that a matter is what its proponent claims it to be. The article recognizes several possible methods, including testimony from a knowledgeable witness, distinctive characteristics, voice identification, and evidence describing a process or system that produces an accurate result.

The Federal Rules of Evidence contain a similar authentication requirement. Federal Rule 902 also addresses certain certified electronic records and data copied from electronic devices, storage media, or files.

These rules do not make every questioned photograph, recording, screenshot, or video automatically admissible or inadmissible. The result depends on the particular evidence, foundation, objections, circumstances, and applicable law.

The practical investigative question often arises much earlier:

Can the source, circumstances, timeline, and supporting facts be documented before litigation decisions are made?

Insurance and claims investigations

Insurance professionals frequently encounter digital photographs, video, online posts, repair documentation, recorded statements, and electronic records.

Artificial intelligence does not make this information useless. It makes context and corroboration more important.

An inconsistency may justify additional investigation, but an apparent inconsistency should not automatically be treated as fraud. Independent information may help clarify what a digital item represents.

Depending on the assignment, relevant information may include documented observations, public records, witnesses, timelines, property or vehicle information, business records, and other lawfully obtained facts.

Business investigations

Businesses face related risks involving impersonation, false identities, fraudulent requests, altered documents, and business-email compromise.

When a questionable communication could affect money, employment, business relationships, internal investigations, or litigation, preserving the original material and verifying the request through an independent channel may be more reliable than trusting its appearance.

Urgency itself can be a warning sign. The FBI recommends resisting pressure to act immediately and independently assessing suspicious requests before providing money or personal information.

Private matters

Private clients may encounter questionable social-media profiles, photographs, recordings, text messages, screenshots, or online identities.

Two assumptions can lead to mistakes:

Believing something must be true because it appears on a screen.
Believing something must be false simply because artificial intelligence exists.

Neither assumption is a substitute for investigation.

The more useful question is whether the information can be corroborated through lawful and reliable sources.

Human investigation still matters

Artificial intelligence can search, organize, compare, and generate information quickly. Investigations frequently require something more: context.

A database may identify a possible person. A photograph may suggest a possible location. A digital record may suggest a possible connection.

The investigator’s role may include determining whether that information actually relates to the subject or matter, documenting relevant facts, identifying inconsistencies, and reporting findings clearly to the client.

Professional investigation increasingly requires separating:

Information from evidence
Possibilities from verified facts
Digital appearances from documented reality

Practical steps when digital material may be important

When a digital item may affect a legal, insurance, business, or private matter:

Preserve the original available file whenever practical.
Record where, when, and how it was received.
Avoid unnecessary editing, conversion, or repeated forwarding.
Preserve related messages, attachments, and contextual information.
Identify people who may have firsthand knowledge.
Look for independent facts that corroborate or contradict the material.
Consult qualified legal counsel regarding preservation and evidentiary obligations when litigation is involved.

A practical principle

The growth of artificial intelligence does not mean photographs, recordings, video, social-media content, or other digital information can no longer be trusted.

It means that high-stakes information should not be trusted without appropriate context and verification.

That distinction matters whether a client is preparing litigation, evaluating an insurance claim, investigating a business problem, locating a witness, or addressing a confidential private matter.
