Digital pic date

[ailie]

Is it possible to alter or fake the date & time shown on the imageof a digital picture? I have been e mailed a JPG in Quick time PRO. The date & time are important & I wonder if they could have been tampered with. Thanx

Well it would be relatively easy to turn the date and time off before taking the picture, and using a simple paint program to add the information afterwards.

And it depends on the settings of the camera the pic was taken on - the camera will show the date it is set to show and the user can set this to anything.

Thanx for that confirmation ladies

There is a date held INSIDE a JPEG file called the EXIF data.

This again would use the date that the camera was set to.

If you can get hold of the original JPEG file, then edit it wth say notepad, near the top will be a string of data including the camera it was taken on, and the date and time.

You could at least confirm the date INSIDE the file is the same as that shown on your QT file.

Here is a picture of the sort of information held INSIDE a JPEG file as EXIF data

VHG - that assumes the user has set the camera date correctly, doesn't it? If you were to set out to deceive, you'd change it

the date and time is subject to the camera being set up correctly - I must have had a hell of a time on the first of january 2000 - 16 holidays - trips to the beach .... that incedent in the park ;o/
and all on the same day!

that's why photographic evidence isn't used unless it's from a reliable source

Which is why I said:

But it may be still worth checking to see if the EXIF date is the same as the date shown on the QT image.

The person may not be aware that the EXIF data exists (maybe)
