Please remove all EXIF data

[FreezerBoy]

gosh!
I've not been safe at all on here. I am not that good at all this computer stuff to begin with and it was a feat for me just to post. But now can I go back an do any of the suggestions on this thread to pics that i have posted already

Maybe not. While I strip data, the closest it came to incriminating is the camera model. There must tens of thousands of my model out there. If you're "not that good at all this computer stuff to begin with" chances are you never figured out how to add the camera data needed to pick you out of a crowd.

Do a "Get Info" or PC equivalent on your photos and see what comes up.

interesting........now ya got me think, again...hmmmm.

 

[Oklekt]

Anyone know how to wipe the info off an iPhone camera pic?

Shouldn't we have a sticky about posting photos?

there are several freewares that can wipe info off pictures like
JPEG & PNG Stripper and BatchPurifier LITE

I would be very surprised if LEO couldn't easily trace the sale of any serial numbered product to the actual store it was sold in.(for at least 7yrs in Canada...a business is required by law to retain records for 7yrs).
So no matter what, they can easily find out what store it was sold at. That hits close to home if you're the hunted.

If you payed in any way other than cash...your name is on it.
If you registered the product...your name is on it.
Even if you payed cash at a membership store(like Costco)...your name is on it.

What are the odds of LEO givin' a shit via the internet? Slim IMHO.

So since I bought mine today and paid with cash and did NOT buy a warrenty and I did NOT go to cosco then I should be ok with posting my pics correct?

 

[FreezerBoy]

You may have been safe already. Take a shot, put it on your puter and "Get Info" or PC equivalent. Mine displays no serial number, the camera model displayed is a very popular model from a very popular manufacturer and only narrows the field to 1 of 100,000 or more. Not very incriminating.

I still strip the data with Image Ready (part of Adobe CS aka Photoshop) but mainly because it knocks a 1MB pic down to 40K.

Well it's a start But ya...your name isn't attached to that camera.
As mentioned...a bunch of different programs will erase the camera data from the pic file...but one thing I like to do as well is turn off the date stamping...it should be an option on most cameras.

Speaking for my camera only, every time I change batteries, the clock resets to several years ago, midnight, Jan 1st.

 

[SKUNK420]

I use THIS

Not only does it remove the EXIF info, it also can add a watermark/logo of your your choice, and it reduces the byte size in 3 popular web sizes. (which saves bandwidth/cost for site owners) Nifty. It is shareware, but in over a year now I havent as so much even seen a nag screen.

worked for me, thanks. free 30 day trial.

I leave the batteries out of my camera entirely until Im ready to take pics. After pics the batteries are removed again.
An idle camera will drain batteries just from storing date and time and stuff. Saves batteries and wipes some of the stored data like user configured settings.

 

[GivaDogaBone]

In windows, I right click on the picture, then click properties.

Click details, then "Remove personal info"

Does this work?

 

[Holmes Slice]

Am I missing something here? How dangerous is it that people might know the camera model and settings when I took the pic? As long as I am not stupid enough to set up my camera with my Author name, who cares?

 

[ItsGrowTime]

It's not really dangerous unless you're doing other stupid stuff like posting identifying info in the pics themselves. There's a little too much paranoia over stuff like this IMO.

 

[Skip]

Does this work?

Yes, that should. You can check by viewing the properties of the image again. Your personal data should be removed.

 

[TooNormal]

One other thing to be sure of...

ICMag tends to reduce/compress photos further, so it doesn't apply here as much, BUT...

If the site allows full- or near-full res photos to be posted - DON'T DO IT. Forensic camera identification via pixel defects IS possible (Google the phrase - I'm not going to post links, since many docs/abstracts are hosted at .gov addresses).

Always downsize that 8M-pixel image to something more web-friendly (like 800x600) to minimize the ability of doing image analysis based on noise/defect patterns.

Removing your Exif data from pictures

Removing your Exif data from pictures

Hey guys!

I didn't find much info on how to remove the Exif files from pictures and what programs to use, so i decided to make a little list of programs to use.

For those of you who don't know what Exif files are its a part of your image file that tells you more info about the picture, such as what camera was used and much more.
So when uploading pics from your harvest its pretty important to be as safe as possible, and deleting your Exif data removes any info about you/ your camera from the image file.

Note that i'm not a pro when its comes to metadata etc, i just got this idea to make a list of programs to use.


For more info on Exif – Wikipedia


Check if your pictures contain Exif data

Exif Reader

exifpro

there is also an addon for Firefox that can view pictures Exif data


Programs to delete your Exif data with

Jhead - (Howto)

I have been using it for years, and I have tested the metadata afterwords to make sure it removed all. There is a neat Firefox add-on that can be used to read metadata on any pic on a website, I have tested pic members have uploaded and it works, showing the metadata.

The code used to run Jhead is important, if the wrong code (batch) is used then all metadata might not be removed. This is my simple batch file I use; this way I can remove metadata in lots of pics (inside the same directly) very easily by simply running the bat file:

"purge_metadata.bat"

@echo off

jhead -purejpg *

pause

Quick Image Resizer – Good program that will strip your image, can also add a watermark (i think its called) on the picture

Batch Image Resizer

Jstrip

JPEG & PNG Stripper

JPEG Cleaner

FastStone

There is also some other methods ive heard people using, like viewing the picture and pressing Print screen and then copying it to paint to save it as normal, apparently this removes the Exif file.

Photoshop also has the option to "save to web" or something like that, this will also remove the Exif file they say.


Keep it safe!

FG

Glad you beat me to it! I was gonna write this tread this week

Exif data is metadata, there is more to remove than only Exif data IIRC.

AFAIK and from my testing Jhead removes dangerous metadata, etc. Who/where is it claimed that Jhead doesn't remove dangerous metadata? I have been using it for years, and I have tested the metadata afterwords to make sure it removed all. There is a neat Firefox add-on that can be used to read metadata on any pic on a website, I have tested pic members have uploaded and it works, showing the metadata.

The nice thing about metadata is up until recently most camera's didn't include GPS data, now many do. Thus turning off GPS is important in all cameras and video cameras and phone cameras.

The code used to run Jhead is important, if the wrong code (batch) is used then all metadata might not be removed. This is my simple batch file I use; this way I can remove metadata in lots of pics (inside the same directly) very easily by simply running the bat file:

@echo off

jhead -purejpg *

pause

I wrote a how to for using Jhead a few years ago, I can post it here if you like. My how-to is easy for people to follow, unlike the Jhaed site that most people see as Latin.

 

[spurr]

Hrm. It looks like

BB code is not enabled here at ICmag. Lame...

@echo off

jhead -purejpg *

pause

Haha well nice to see theres interest

Jhead removes all metadata, etc. I have been using it for years, and I have tested the metadata afterwords to make sure it removed all.

I guess its safe to say that it DOES remove all the data then?

There is a neat Firefox add-on that can be used to read metadata on any pic on a website, I have tested pic members have uploaded and it works, showing the metadata.

Is that the same one as i posted in the first post?

The nice thing about metadata is up until recently most camera's didn't include GPS data, now many do. Thus turning off GPS is important is all cameras.

Yeah its pretty scary, heard from a cop that works with busting growers (fucker) that alot of times they just go on the net looking for people who have been taking pictures of their grows with iphone etc, and all the GPS localizations are there

I wrote a how to for using Jhead a few years ago, I can post it here if you like. My how-to is easy for people to follow, unlike the Jhaed site that most people see as Latin.

Would be great if you could post it! Ill add it to the first post.

 

[Freedom Grows]

Did my thread just get merged with this one or did i fuck it up?

Anyway updated my first post, hope its no problem that i quoted you spurr!
