Detailed Description

Ingest module to parse image Exif metadata. Currently only supports JPEG files. Ingests an image file and, if available, adds it's date, latitude, longitude, altitude, device model, and device make to a blackboard artifact.

boolean org.sleuthkit.autopsy.modules.exif.ExifParserFileIngestModule.parsableFormat ( AbstractFile  f )

private

Checks if should try to attempt to extract exif. Currently checks if JPEG image (by signature)

Returns

true if to be processed

ProcessResult org.sleuthkit.autopsy.modules.exif.ExifParserFileIngestModule.process

(

AbstractFile

file

)

Processes a file. Called between calls to startUp() and shutDown(). Will be called for each file in a data source.

Parameters

file	The file to analyze.

Returns

A result code indicating success or failure of the processing.

void org.sleuthkit.autopsy.modules.exif.ExifParserFileIngestModule.shutDown

(

)

Invoked by Autopsy when an ingest job is completed (either because the data has been analyzed or because the job was canceled - check IngestJobContext.fileIngestIsCancelled()), before the ingest module instance is discarded. The module should respond by doing things like releasing private resources, submitting final results, and posting a final ingest message.

void org.sleuthkit.autopsy.modules.exif.ExifParserFileIngestModule.startUp

(

IngestJobContext

context

)

throws IngestModuleException

Invoked by Autopsy to allow an ingest module instance to set up any internal data structures and acquire any private resources it will need during an ingest job. If the module depends on loading any resources, it should do so in this method so that it can throw an exception in the case of an error and alert the user. Exceptions that are thrown from process() and shutDown() are logged, but do not stop processing of the data source.

Parameters

context

Provides data and services specific to the ingest job and the ingest pipeline of which the module is a part.

Exceptions
