Neville wishes to ensure that his forensic work cannot be repudiated. How can he verify his statements and documents to guarantee non-repudiation?

Although encrypting the output will secure its confidentiality, it alone will not establish non-repudiation. While MD5 checksums are typically collected for images, they must also be signed to be verified and ensure they have not been altered.
