Fight Deepfakes: Verify Digital Content with On-Chain Provenance

Deepfake technology has emerged as a significant threat. The ability to create realistic images, videos, and audio that are indistinguishable from real creates serious problems.

From altered political speeches to false celebrity endorsements, deepfakes get to erode trust and spread misinformation. They also tend to disrupt social and political forces.

Erosion of trust becomes a huge issue when traditional forms of fraud detection like fact-checking and watermarks because of the sheer volume of deepfakes.

On-chain provenance is a new method of tracking and proving the authenticity of digital assets through blockchain technology.

Understanding On-Chain Provenance

On-chain provenance refers to the process of inscribing specific details about a digital asset directly onto the blockchain.

Unlike a traditional centralized system where records can be changed, removed, or counterfeited, a blockchain records are immutable as well as being permanently time-stamped.

This provides robust assurances of security for digital media records. Therefore, each digital media asset can be associated with a permanent record of its creation, ownership, and alteration history as well as associated metadata that can be independently verified.

Examples of this type of metadata can include the name of the creator, date of creation, name of the device or software that created the digital asset, as well as any cryptographic references to the media and its location.

Because the metadata that is associated with the media is altered to create a permanent record of the asset’s provenance, this information can be used to verify the authenticity of the asset.

What is on-chain Provenance?

On-chain provenance encompasses the tracking of a digital asset’s history, sources, and ownership, directly on a blockchain.

Provenance saves the details of its creation, records of modifications and custody, and the metadata that timestamps the history, ensuring that the asset can always be verified as authentic. The history of the asset can be verified or authenticated.

It allows tracking of the asset to its sources, and, as a result, provides a secure, transparent, and trustworthy means of verifying digital assets. It removes the potential for alteration or forgery of the asset and enhances the verification of digital assets in the media, art, and legal fields.

Deepfakes and the Threat of Misinformation

Deepfake tools allow the manipulation of real and fictional audio-visual content for artistic and entertainment purposes.

However, the malicious potential of deepfake tools for spreading false narratives, damaging reputations, and influencing the majority’s opinion and beliefs poses a significant threat.

The problem is further exacerbated as the malicious content created using deepfake tools goes viral much faster than fact-checkers or digital platforms combat the false narratives and the potential damage that may arise from them.

Existing deepfake detection methods, which are largely based on forensic detection and watermarking, are limited in their effectiveness.

Watermarks are also easily altered, added, or removed, which diminishes their effectiveness. On-chain provenance detection is much more effective in that it prevents forgery from the source of the digital asset, which also provides on-chain traceability.

The digital trail created includes the creator’s identity, creation time, the device and/or software used, cryptographic hashes of the created digital asset, and even the geolocation of the creator.

Once this information is written to the blockchain, it is permanent and cannot be altered, which preserves the provenance of the digital asset.

How Metadata Combats Deepfakes

Encryption is like a digital fingerprint. Each time a digital asset is created metadata is generated, which can then be time-stamped and recorded into the blockchain.

If the digital asset is ever deepfaked, no matter what the source is, the deepfake will be unable to be passed off as the source asset and will fail the verification as the deepfake asset will not be congruent to the source blockchain hash.

This allows verification to be done by any platform, journalist, consumer, etc. and eliminates the need to rely on any centralized entity.

Also, metadata can record the chain of custody. In journalism and scientific research, for example, all the editors, collaborators, and AI, etc., can be recorded on the chain.

This transparency increases accountability by reducing the risk of content tampering. Users are able to trace the content back to the beginning to see whether and how it was altered.

Who Benefits from using on-chain Provenance?

Journalists – With on-chain provenance integrating within web3 technology, journalists can now securely publish content and have articles or media assets verified, traced, and authenticated.

Digital artists & NFT creators – Provenance protection secures the initial creation of an asset and protects the rights of the creator, especially against unauthorized duplications or deepfake alterations.

Legal authorities – Courts and law enforcement can digitally authenticate evidence, including the chain of custody, details of modifications, and history prior to and during litigation.

Social media platforms – By implementing blockchain technology, social media platforms can identify and authenticate fake or manipulated content, ultimately limiting the spread of deepfake videos and other types of misinformation.

Real World Applications

Numerous industries are already researching potential applications of on-chain provenance in efforts to fight deepfakes and misinformation:

News Media: Due to the presence of deepfakes and misinformation, the media is losing credibility. However, they can regain consumers trust by attaching blockchain metadata to verified multimedia, allowing consumers to trust the authenticity of the media.

Legal Evidence: Courts and law enforcement can use on-chain provenance to verify the authenticity of the digital evidence. This means that the videos and images that are presented in the case have been tampered with.

NFTS & Entertainment: Digital artists are able to protect themselves from having their work deepfaked or duplicated by attaching metadata to the nft. Additionally, they can sell the digital work as an nft, allowing consumers to own the work or video.

Social Media: Verification of social media on an ongoing basis is possible using on-chain provenance.

Challenges and Limitations

It is important to note that, although on-chain provenance can provide numerous advantages, the absence of widespread adoption will ultimately limit its potential.

All content creators and platforms are required to record and verify metadata. There are also concerns regarding privacy, as the creator’s identity could be exposed along with sensitive information, such as their location.

Another significant issue that needs to be addressed is improving user access. It is possible that not all consumers possess the technical skills needed to verify the metadata on the blockchain.

User interfaces will need to be designed to integrate the verification tools in ways that make the verification process as easy as possible.

What are the limitations of on-chain provenance?

• Adoption: Both creators and platforms need to participate for the system to work widely.
• Accessibility: Non-technical users may need intuitive tools for verification.
• Cost & scalability: Writing large amounts of data on some blockchains can be expensive.
• Privacy trade–offs: Balancing transparency with sensitive data protection is critical.

The Future of Digital Trust

Record-keeping with metadata remain immutable like time capsules, as described by the author, where the creator of the media is the only person

Who can keep the record of the media fully confidential, and combine the media with cryptographic technology transparently, accountably, and trustworthily implicates the record will keep all the produced media trustworthy.

This technology will not only record the instances where media have been altered, deceived, or altered, deceived, or otherwise manipulated

But will also have the potential to supplant the extant regulations of media alteration, deception, trickery, and manipulation, as gone will be the days of the media.

Increasingly, and as the media continues to evolve, accurate and trustworthy evidence is needed. Provenance within the media, as described by the author

Will allow all subsequent media to be displayed to combat the continuum of media deception, with the media and the technology of the blockchain as the authors’ greatest source of confidence.
