ExifEraser

JPEG Exif eraser application for Android 6.0+

How does it work?

• Exif uses TIFF to store data
• Exif sits in the APP1 segment and uses the following data structure (shortcut of this lengthy description):
  0xff 0xd8 SOI Marker
0xff 0xe1 APP1 Marker
0x45 0x78 0x69 0x66 0x00 0x00 Exif Header
...
• This application detects the presence of the Exif header in JPEG files,
  and proceeds to strip the entire Exif segment using Apache Sanselan internally
  (without requesting any permissions)
