Review Questions

• How does blockchain technology enhance the trustworthiness of digital images?
  • Blockchain technology enhances the trustworthiness of digital images by providing an immutable record of all transactions related to the image, including its creation and any modifications. This means that photographers and users can verify the authenticity and history of an image easily. By linking images to unique identifiers on the blockchain, any manipulation or alteration can be detected, thus maintaining photo integrity.
• In what ways can photographers utilize blockchain technology to protect their work from digital manipulation?
  • Photographers can utilize blockchain technology to protect their work by securely recording each image along with its metadata on a decentralized ledger. This ensures that any changes made to the image are transparent and traceable. Additionally, attaching copyright information directly to the blockchain allows photographers to maintain ownership rights, making it more difficult for others to misuse or alter their work without permission.
• Evaluate the impact of blockchain technology on the future of news photography and ethical practices in digital media.
  • The impact of blockchain technology on the future of news photography could be transformative, promoting higher ethical standards in digital media. By providing verifiable proof of authenticity and origin for images, blockchain fosters accountability among photographers and news organizations. This could lead to greater trust from audiences as they receive content that is less susceptible to manipulation. As ethical concerns about fake news grow, implementing blockchain may help uphold journalistic integrity by ensuring that visual evidence is both credible and reliable.
