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 | |
|---|---|
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |
| APP2ICC colour profile or FlashPix extension data. | |
| 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. | |
| EOIEnd of Image — the 2-byte marker that closes every valid JPEG file. | |
| SOF0Start of Frame, Baseline DCT — the most common JPEG compression type. | |
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| SOSStart of Scan — marks the beginning of the compressed image data stream. |
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 | |
| XAPEarly Adobe XMP namespace prefix (xap:) used before xmp: was standardised. Seen in older cameras and Photoshop CS versions. |
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 2.31 |

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.
