. . is it dangerous to post in public pictures that are taken with a digital camera that I own?
Posting in public, pictures or no, is one of the most dangerous things a person can do in the 21st Century-- ownership details of the camera notwithstanding. . . If you can think of other ways a user's security could be compromised through the process of them posting a picture they took publicly, please tell me. Thanks! I can. Suppose you were to post a picture of yourself standing in front of your car and house. I can read your license plate and your street address, and notice there's a copy of the 'My Town, USA' Gazette on the front steps. Hey! What's that over there in the corner? Why, it's a street sign with the name of your street on it! And suppose further that you were reading your bank account and credit card statements when that picture was taken, and that account details are easily discernable within the photo. Well, I think it's easy enough to see where this could potentailly create a problem if you were to post said photo in or at a public place. I rest my case. Have a nice day.  That's some panoramic shot ya got there! |

While the OPs concerns may be slightly unfounded, I did learn a lot from that online EXIF viewer.
I run every image through CS2 which creates a new thumbnail. However, the EXIF data contains the RAW conversion values that I used (which really isn't a big deal).
Some folks may not want to give away the date/time of the original image so they should be concerned with the EXIF data. |

Do any cameras include GPS info with them?
I could see some potential problems if coordinates were included with every picture... |

Ricoh makes a GPS capable camera. I'm not aware of any "hidden" GPS capabilities in any cameras, though.
Since cell phones use GPS to locate for 911 service, I could see where the built-in cameras could be configured to include coordinates in the EXIF data. At the least, the time and date EXIF data could be matched to location history if that is stored somewhere in the provider's system, which I believe it is - at least for a short time.
Cell phone experts, whaddya think? Are there any such phones out there that trap coordinates in the camera's EXIF?

I remember when Cat Schwartz from techtv had a problem where she cropped a topless photo of herself and didnt realize the whole photo was viewable in the exif thumbnail...Kevin Rose had a funny post on his site about how to not be like her and remove the EXIF info. |

said by dolphins :Here's a shortened low resolution video I took from a local fire with sound.(DUH!) See what you can do with it? . . . You're right, that video has sound. This is one of the first things I deduced while examining it.
It was also shot from a residential neighborhood near the Delaware River where the houses date from the '50's, the speed limit is 25 mph, and the road could use repaving.
The neighbor three doors down has a little yappy mutt that never shuts up. Lots of guys named 'Vinnie' & 'Rocco' live nearby. Most of the neighborhood kids do surprisingly well in school, except for that one kid a couple of streets over who seems to be a reject from a "Deliverance" casting-call.
The air is generally smoggy, but gets even fouler during the occasional chemical factory fire or when the Phillies lose, which is often.
The camera-person was male, right-handed, had eggs for breakfast, and is not professionally employed as a videographer.
This is for starters. Believe me-- some of the gorier details, you don't even want to hear.
I didn't hear any sireens, either.  |

This article »www.eurekalert.org/pub_releases/···1806.php talks about uniquely identifying digital cameras based on the different ways each individual camera distorts the images.
This does not enable anyone to find you or your camera based on having only a photo from it. However, it could enable technicians to prove that two digital photos came from the same camera; and if they located the camera they could match the photos to it. |

said by Steve :said by NetFixer :Unless you have privacy issues with someone knowing the brand/model of the digital camera you use and/or the timestamp information, the EXIF information is in no way a privacy or security issue. Oh yah? EXIF can contain a thumbnail of the image, and it's often maintained even after the full image has been mucked with in photoshop. I recall a headshot that a pretty girl posted of herself on Craigslist, and though it had been cropped, the original uncropped thumbnail was still in the EXIF. Let's just say we got to see a bit more of the pretty girl than she intended. Woot! Likewise, that racy picture that you pixellated or added black bars to? The thumbnail didn't get those edits. Surprise! See the above sample taken from this site (examples are easy to find, but it's harder to find a "good" one that's nevertheless suitable for posting in a public forum). It's fun to investigate pictures with my brother's online EXIF viewer, which will show thumbnails if the EXIF contains them. This is a classic example of hidden metadata, and photographs are not immune; this makes it a security issue. Steve Wow this is something I did not know! so when you think you have blocked something out it still can be seen? is there a way to get rid of the thumbnails |

Re: Digital camera a security risk?

Obviously, nobody (I would hope) is going to take a picture of their bank statement or whatever and post it publicly.
I think your concerns (*Edit- or should I say the O.P.'s concerns) are completely valid. Some laser printers now include 'unique' tracking numbers/devices/whatevers.
Though I think, at least for now, most cameras or imaging programs come with settings to where you can disable at least most of that stuff if so inclined.
Tracking is big nowadays. Microsoft wants a clear channel into the computer, RFID chip talk is the latest fashion, you've got GPS & Lojack on cell phones, computers, and in your car.
Surely a 'unique identifier' or tracking chip of some sort on your personal digital camera is not out of the question.
Much less the gathering and dissemination of less-than-public info with cloaking and user ignorance serving means of transferral.
I'd keep a sharp eye on my image-related settings & what-not. Just on G.P.'s. |
