Prove Every Job Photo With Tamper-Proof Data
Can you really trust a job photo? Was it actually taken on-site, at the time it claims? Research from the National Institute of Standards and Technology shows that image metadata such as GPS coordinates, dates, and times can be incomplete, missing, inaccurate, or quietly altered without changing the picture itself.
As highlighted in further industry research, there is a clear "need for lightweight authentication solutions to detect basic tampering in field-collected images." That is exactly where TimeMarkerGps comes in: it works as your on-site photo authentication tool, sealing secure capture data like a digital fingerprint so you and your clients can confirm authenticity instantly, straight from the camera.
