DMC-FZ1000
What this fingerprint profile shows
Every photo taken by a DMC-FZ1000 carries a consistent set of metadata patterns — written automatically by the firmware at the moment of capture, regardless of any app or privacy setting. The signals below are derived from 7 analysed files and document exactly what this device embeds in every image it creates.
GPS rate — how often this device records your precise location in the file, even when you don't realise GPS is active
DQT compression fingerprint — a unique 64-value matrix baked into the firmware that identifies this camera model even after EXIF metadata has been stripped
MakerNote & firmware strings — proprietary manufacturer data and firmware version tags that reveal processing history, lens details, and scene settings
Privacy risk signals — owner name, body serial number, and lens serial number fields that may contain personally identifying information

Your DMC-FZ1000 embeds these signals in every photo you share.
Strip with VaultifyEmbedded ThumbnailA small JPEG preview stored inside the EXIF APP1 segment, written at capture. May differ from the full image if the file was post-processed.
Rate at which this device embeds a thumbnail in the EXIF APP1 segment.
IPTC Metadata RateInternational Press Telecommunications Council — an editorial metadata standard for captions, copyright, and keywords. Usually added by software rather than written by cameras at capture.
Percentage of files that included IPTC metadata (typically editorial or copyright data).
APP14 SegmentAdobe colour transform marker — a JPEG segment storing a single byte that tells decoders how to interpret YCbCr colour channels when converting to RGB.
APP14 (Adobe color transform marker) presence rate.
Color transform values observed:
| Observed value | |
|---|---|
| 1 |
SOF Compression TypeStart of Frame marker — identifies the JPEG compression algorithm. SOF0 = baseline DCT (most common); SOF2 = progressive DCT (multiple passes, common in web-optimised images).
JPEG compression markers (SOF0 = baseline, SOF2 = progressive).
| Observed value | |
|---|---|
| SOF2 |
DQT Quantisation Table FingerprintsThe 64-value matrix that controls JPEG lossy compression. Baked into firmware — consistent across units of the same model — and distinctive enough to act as a camera fingerprint.
JPEG quantisation table fingerprints. Identical patterns across devices indicate shared hardware or firmware lineage.

JPEG Segment InventoryThe set of JPEG markers consistently present in output from this device. Marker presence and order are firmware-determined and can help distinguish camera lineages.
APP and SOF segments consistently present in output from this device.
| Observed value | |
|---|---|
| SOSStart of Scan — marks the beginning of the compressed image data stream. | |
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| DQTDefine Quantization Table — the 64-value lossy compression matrix. Consistent per firmware; useful as a fingerprint. | |
| DHTDefine Huffman Table — the compression lookup table baked in by the encoder. | |
| APP2ICC colour profile or FlashPix extension data. | |
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |
| APP13IPTC data container — used by Photoshop and some cameras for editorial and copyright metadata. | |
| SOF2Start of Frame, Progressive DCT — encodes in multiple passes; common in web-optimised images. | |
| APP14Adobe colour transform marker — stores a byte indicating how YCbCr channels map to RGB during decoding. |
Metadata Block TypesThe metadata container formats found in files from this device — EXIF, IPTC, XMP, JFIF, and others. Different devices and software pipelines embed different combinations.
| Observed value | |
|---|---|
| Exif | |
| IPTCInternational Press Telecommunications Council — editorial metadata: captions, copyright notices, keywords. | |
| XMPExtensible Metadata Platform — Adobe's XML-based metadata layer for editing history, rights, and additional descriptive data. | |
| Photoshop 3.0 | |
| ICC_PROFILE | |
| Adobe |
EXIF VersionThe EXIF specification version string written by the device's firmware. Not user-adjustable — a firmware constant that can indicate manufacturing era.
EXIF specification version string encoded by this device's firmware. Not user-adjustable — firmware constant.
| Observed value | |
|---|---|
| 0230 |
Software / Firmware StringsValues written to the EXIF Software tag — may reflect firmware version, in-camera processing software, or the desktop application used to export the file.
Values written to the EXIF Software tag by this device or its associated software.
| Observed value | |
|---|---|
| Adobe Photoshop 23.1 (Windows) |
ICC Colour ProfilesInternational Color Consortium profile — an embedded colour space definition telling displays and printers how to reproduce image colours accurately. Profile name often encodes the camera's target colour space.
Colour profile names embedded by this device.
| Observed value | |
|---|---|
| sRGB IEC61966-2.1 |
Y/CbCr PositioningSpecifies how chroma channels (Cb, Cr) align with the luma channel (Y) during colour subsampling. Centred (1) or co-sited (2) — a firmware preference. Canon typically writes 2; Nikon and Sony write 1.
Colour channel alignment encoded by this device (1 = centred, 2 = co-sited). Manufacturer-determined — Canon typically writes 2, Nikon and Sony write 1.
| Observed value | |
|---|---|
| 2 |
XMP NamespacesXML namespace URIs present in XMP metadata from this device. The set of namespaces reveals which software pipeline created or processed the file.

Your photos carry this device fingerprint.
Vaultify strips device metadata before sharing — and can hide a private message inside your photo, invisible to forensic scanners like these.
