SM-A530F
What this fingerprint profile shows
Every photo taken by a SM-A530F 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 16 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 SM-A530F embeds these signals in every photo you share.
Strip with VaultifyMakerNote 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.
| Observed value | |
|---|---|
| 4608x3456 |
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 | |
|---|---|
| SOF0Start of Frame, Baseline DCT — the most common JPEG compression type. | |
| 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. | |
| SOSStart of Scan — marks the beginning of the compressed image data stream. | |
| APP1Primary metadata container — holds EXIF camera data (make, model, GPS, settings) and optionally XMP. | |
| APP4 | |
| SOIStart of Image — the 2-byte marker that opens every valid JPEG file. | |
| EOIEnd of Image — the 2-byte marker that closes every valid JPEG file. | |
| APP0JFIF application marker — identifies the file as JFIF format and may carry thumbnail and pixel density info. | |
| APP5 | |
| APP11 |
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. |
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.
| Observed value | |

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.
