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.
Restart Interval (DRI) RateDefine Restart Interval — a JPEG marker that splits the compressed stream into independently-decodable blocks to aid error recovery. Canon cameras include it consistently; most others do not.
Rate at which this device writes a DRI (Define Restart Interval) marker. Canon cameras consistently include this; most Nikon, Sony, and smartphone output does not.
Output DimensionsImage resolution values (width × height in pixels) observed across analysed files from this device.
Image resolution values observed for this device.
| Observed value | |
|---|---|
| 4032x1816 |
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 | |
|---|---|
| SOF0 |
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 | |
|---|---|
| DQTDefine Quantization Table — the 64-value lossy compression matrix. Consistent per firmware; useful as a fingerprint. | |
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |
| EOIEnd of Image — the 2-byte marker that closes every valid JPEG file. | |
| SOF0Start of Frame, Baseline DCT — the most common JPEG compression type. | |
| SOSStart of Scan — marks the beginning of the compressed image data stream. | |
| DHTDefine Huffman Table — the compression lookup table baked in by the encoder. | |
| APP5 | |
| DRIDefine Restart Interval — written by some cameras (notably Canon) to enable mid-file error recovery. | |
| APP4 | |
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| APP0JFIF application marker — identifies the file as JFIF format and may carry thumbnail and pixel density info. | |
| 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 | |
| debuginfo | |
| JFIFJPEG File Interchange Format — a baseline format header. Often absent from camera-original files; common in scanned or web-converted images. |
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 | |
|---|---|
| Exif Version 2.2 |
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.
