GPS Metadata RateThe proportion of files where this device embedded GPS coordinates — from an on-board receiver or a paired smartphone.
Percentage of files from this device that contained GPS location data.
MakerNote PresenceA proprietary manufacturer block inside EXIF whose format is largely undocumented. Contains settings not in standard EXIF — focus mode, scene detection, lens data, processing flags.
Rate at which this device embeds a MakerNote block (proprietary manufacturer metadata).
Output DimensionsImage resolution values (width × height in pixels) observed across analysed files from this device.
Image resolution values observed for this device.

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).

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 | |
|---|---|
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |
| DHTDefine Huffman Table — the compression lookup table baked in by the encoder. | |
| DQTDefine Quantization Table — the 64-value lossy compression matrix. Consistent per firmware; useful as a fingerprint. | |
| SOF0Start of Frame, Baseline DCT — the most common JPEG compression type. | |
| SOSStart of Scan — marks the beginning of the compressed image data stream. | |
| APP0JFIF application marker — identifies the file as JFIF format and may carry thumbnail and pixel density info. | |
| APP2ICC colour profile or FlashPix extension data. | |
| EOIEnd of Image — the 2-byte marker that closes every valid JPEG file. | |
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| TRAIL |
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 | |
| JFIFJPEG File Interchange Format — a baseline format header. Often absent from camera-original files; common in scanned or web-converted images. | |
| ICC_PROFILE | |
| XMPExtensible Metadata Platform — Adobe's XML-based metadata layer for editing history, rights, and additional descriptive data. |
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 | |
|---|---|
| 2.2 | |
| Exif Version 0.022 |
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 | |
|---|---|
| Display P3 |
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.

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.
