There are dozens of such tags, and each one can help tell a very distinct story this is why understanding how rich metadata is can better help protect the identities of sources who have shared their digital media with you. Other interesting tags include the “Make” and “Model” tags, which can tell you what type of camera or computer was used to create the media. One of the simplest tags is “Creation Date,” which naturally points to the time when its creator pushed the shutter button, or pressed record. But if you pry into any digital artifact, you can see metadata as a list of keys (or tags) and their corresponding values. Metadata exists in the parts of images, videos, or music that we can’t experience as humans. But in the wrong hands, this same information could be damaging. This information comes in handy sometimes, like when you’re flipping through old pictures by date, or by location. It describes the who, what, when, where, how, and sometimes even, why, for any document, video, photo, or sound clip. the 'unrestricted access' phrase is throwing me off kilter, as you can see.Metadata is data about data. I install many apps which ask for my login info in order to install portions of themselves into protected directories, but in that case the language is quite a bit different. since your app-once installed-should have the same privileges as my user, i don't quite see why it can't run my user doesn't have root access, but is able to access What bothered me is the line about requesting 'unrestricted access' which to me means root.
#EXIFTOOL MAC VERIFY INSTALL DIRECTORY UPDATE#
The certificate and the update function don't bother me at all-especially since you are publicly posting and answering questions. and i do really appreciate you coding a gui frontend for the exiftool that runs on the mac. PhotoGrok is signed with a certificate I generated Java Web Start automatically updates PhotoGrok when a new version is available. PhotoGrok needs to call another program (ExifTool) so it needs additional privileges. It's normally unobtrusive and fast and I'd like to take advantage of this feature to keep all clients up to date with the latest features. This happens whenever the app is started. To do this it does a timestamp check of the PhotoGrok components on my web site. Either way, you're making a decision about whether to trust the developer.Īs far as contacting the developers site, Java Web Start automatically updates PhotoGrok when a new version is available. Trusting the certificate is not any different from downloading an exe or other utility (like ExifTool itself) from the web. If you agree to trust the certificate, there is an option on the dialog so you don't have to see the warning again.
#EXIFTOOL MAC VERIFY INSTALL DIRECTORY SOFTWARE#
PhotoGrok is signed with a certificate I generated because I cannot afford to pay several hundred dollars for a code signing certificate from Verisign or one of the other vendors.at least not for software I'm making available for free. In order for any Java Web Start or Java applet to access features outside the security sandbox it needs to be signed with a certificate.
