Bank of America appears on both legitimate first-generation output and downstream re-save flows — context (the other tool on the same document) is what flips the signal.
Back to all statisticsForensic verdictBased on this tool’s share of the HTPBE? corpus.
Corpus profile
Bank of America is one of the PDF-handling tools surfaced in the HTPBE? corpus. Bank of America appears predominantly as the original Creator (93% of its occurrences) — i.e. on documents that started life inside Bank of America rather than passing through it as a downstream re-saver.
In the HTPBE? corpus the contextual signal we look for is a producer/creator mismatch: when Bank of America appears as the latest Producer on a document whose Creator was an institutional source (e.g. Adobe PDF Library, Microsoft Word, a banking back-end), the document was rebuilt or re-saved after its original creation. That mismatch is the marker — never the tool itself.
On documents where Bank of America acts as Creator, 86% carry modification markers; on documents where it acts as Producer, 100% do. These are observed rates inside the HTPBE? corpus and should be read as base-rates, not as accusations against Bank of America or its users.
Role in the workflow
Every PDF carries a Creator (the application that produced the original document) and a Producer (the engine that wrote the PDF). The same tool can appear in either slot, with very different modification profiles.
Distributions
The PDF versions Bank of America writes when acting as Producer, and the other tools that appear in the same documents.
Most output is PDF 1.6 (100% of files where Bank of America is the Producer).

Long tail
Smaller cuts of the Bank of America corpus — useful context, but treat each row as a single data point rather than a strong signal.
