McAfee later claimed to have edited the Exif data from his phone to provide a false location. [26] According to documents leaked by Edward Snowden, the NSA is targeting Exif information under the XKeyscore program. [27] The privacy problem of Exif data can be avoided by removing the Exif data using a metadata removal tool. [28]
ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, video, and PDF metadata.As such, ExifTool classes as a tag editor.It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application.
File renaming, single-click background copy/move to preset location, single-click rating/labeling (writes Adobe XMP sidecar files and/or embeds XMP metadata within JPEG/TIFF/HD Photo/JPEG XR), Windows rating, color management including custom target profile selection, Unicode support, Exif shooting data (shutter speed, f-stop, ISO speed ...
The Samsung SH100 can connect using Wi-Fi to get position data from a GPS-enabled smartphone. [5] Generally the relevant GPS data is automatically stored in the photo's Exif information when the photo is taken. A connected GPS will generally remain switched on continuously, requiring power, and will then have location information available ...
Exif Since many JPEG editing software used to destroy Exif metadata stored in digital photos, some photo cataloging applications can extract the Exif data and store that in an .exf file, so that the metadata can later be re-inserted into the JPEG file. Raw + JPEG
Similarly, images containing Exif GPS location information [21] can be grouped together according to a user-specified distance criteria. This feature does not requires a reference point (i.e. it does not "search" for images taken near a given time or near a given location) but instead looks at the time taken or location of all images together ...
XnView can show IPTC, Exif and XMP metadata, and write IPTC metadata (It can also do batch writing of IPTC metadata). [15] [16] It can write XMP metadata partly together with IPTC metadata. It also supports file comments (4DOS descript.ion). XnView can search files that have the same filename or data, and can search for similar graphics as well.
The NavPix, therefore, effectively provides a Georeference of the location where the image was taken, which is not necessarily the same georeference as the object being "NavPix-ed". The NavPix image can then be used to define a destination or point of interest on compatible Navman devices.
