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.
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).
Output DimensionsImage resolution values (width × height in pixels) observed across analysed files from this device.
Image resolution values observed for this device.
| Observed value | |
|---|---|
| 384x256 | |
| 512x512 |
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.

| SOF0Start of Frame, Baseline DCT — the most common JPEG compression type. | |
| SOSStart of Scan — marks the beginning of the compressed image data stream. | |
| DQTDefine Quantization Table — the 64-value lossy compression matrix. Consistent per firmware; useful as a fingerprint. | |
| EOIEnd of Image — the 2-byte marker that closes every valid JPEG file. | |
| DHTDefine Huffman Table — the compression lookup table baked in by the encoder. | |
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |

| CHRM | |
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| APP13IPTC data container — used by Photoshop and some cameras for editorial and copyright metadata. | |
| APP0JFIF application marker — identifies the file as JFIF format and may carry thumbnail and pixel density info. |
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. | |
| Photoshop 3.0 | |
| XAPEarly Adobe XMP namespace prefix (xap:) used before xmp: was standardised. Seen in older cameras and Photoshop CS versions. |
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.

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.
