A security officer at an organization that makes and sells digital artwork must ensure the integrity of the artwork can be maintained. Which of the following are the best ways for the security officer to accomplish this task? (Choose two.)
o Hashing: Using a cryptographic hash function like SHA-256 creates a unique fingerprint for the artwork. Any changes to the artwork will result in a different hash, allowing the security officer to easily detect tampering.
o Watermarking: Embedding a subtle watermark within the artwork allows for identification of the original source and can help prevent unauthorized modifications.
Implementing hashing and watermarking provides a comprehensive approach to maintaining the integrity of digital artwork. Hashing allows for verification of file integrity through checksums, while watermarking embeds ownership and authenticity information directly into the artwork, deterring unauthorized use and providing proof of ownership. Together, these measures help protect the organization's digital assets and ensure that customers receive genuine and unaltered digital artwork.
