DeepCheck

DeepCheck scans a WhatsApp export for anomalies. It reads its digital fingerprint and surfaces anything that needs to be reviewed. Add optional chain of custody details and they are logged, with a trusted timestamp, against this DeepCheck in your dashboard.

Matter for your internal labelling only, not sealed

Chain of custody sealed with the analysis

The chain of custody details are optional. They are sealed into the analysis, under the trusted timestamp, at the moment you run it, and cannot be added or changed afterwards. The matter name and reference are not part of the analysis: they are your own filing labels and can be changed at any time.

Running DeepCheck uses one DeepCheck credit. The file's SHA-256 hash, the chain of custody details you enter and the moment of analysis are sealed under an RFC 3161 trusted timestamp and form a permanent part of the analysis itself — a chain-of-custody record fixed at a verifiable point in time.

Your export is deleted as soon as it has been read. Nothing is kept unless you run DeepCheck: otherwise the reading is discarded when you leave this page, or after an hour.

What DeepCheck does

Examines the export file
DeepCheck forensically analyses the WhatsApp export itself. The metadata inside it forms the export's digital fingerprint, and DeepCheck tests that fingerprint's internal consistency for signs of irregularity.
Gives a clear result
The export either passes every integrity check, or an anomaly is surfaced for review, pointing to the messages or media files concerned.
Issues a report for the file
The result is set out in a Chatsward DeepCheck Report, a document separate from any PDF of the chat, kept in your audit trail under its matter if you give it one.
Stays private until you share it
Only you can see the result. You can share it on Verify, so that anyone holding a PDF of this export can see it too, and stop sharing at any time.

DeepCheck does not establish the identity of the person operating a WhatsApp account. It addresses the integrity and provenance of the export itself, leaving questions of attribution to the wider evidential picture.

Run without chain of custody details?

The chain of custody details are blank. They are sealed into this analysis with the trusted timestamp at the moment it runs — they cannot be added or changed afterwards.
