Protect files from manipulation

Hi,
I have a question about JAR deployment. In my program, I have a lot of properties, and I want to externalize them (e.g. in an XML file, or similar) to make manipulation for the rest of the team easier.
However, in the final state, I don't want the customer to access this data.
How can I protect my data from manipulation? Can I forbid the decompression of the JAR file, and still allow execution of it? Or is there another way to achieve what I want?

It's all about making it harder. I know that. People that post these questions don't always know that. This OP seems to know that, but the way he talked about this case left me unsure whether he realized it just makes it very hard, or thought it actually made it impossible.
It's nonesensical to
talk of "do this, but it's still possible to get
around ..." in terms of security implemetation. No, it's not. It's worth driving the point home to people that think that encrypted classes, etc. will make their Java code impossible to reverse engineer. It's worth clearing up that little misconception.
Yes,
it's possible, but yes it's also now harder then it
used to be. Keep adding these things on and it
becomes harder and harder and harder. You don't get
anywhere if you just kill the whole idea from the
start.I'm not killing the whole idea from the start. I'm merely attempting to make sure the OP (and anyone else who happens to be perusing this thread) is clear that it's only hard, not impossible. Like I said, I think this OP gets that, but it doesn't hurt to be sure.

  • How to to transfer protected files from one computer to another

    i was wondering how to transfer protected files from my small computer and delete them to free up space and put the on my new larger comptuer.

    Locate them in the Windows Explorer, move them to the new computer as you would any file, and then drag them into the open iTunes window. They can then be deleted from iTunes on the old computer.

  • How can I protect files from being uploaded to the internet/web-based email or being written to a disc/flash drive?

    I work for a company that want to update itself to this century.  I got all our PC upgraded to Windows 7 and networked into a homegroup.  We want to use a web-based appointment scheduler but this means giving our users web access.  The main
    concern is our .mdb files.  We have anti-virus/anti-spyware to protect us from infiltration but we want to safeguard against personnel selling our client list; At least make it more difficult, just a precautionary measure.  Do I need additional software
    or is it something that I can do in Windows setting?  Or do I need a file encryption service that works in conjunction with Windows Access?  Sorry for my ignorance and thanks in advance.

    There is technology known as RMS which you could set series of policies like only members in the company could access certain documents and if someone copy them and attempt to run them in another PC or outside company, it won't work. Take a look at:

  • Opening a hyperlinked password protected file from another Adobe File

    I have a user that has a table of contents pdf file. This file links to other files in the same directory. Originally in XP she would click on the link and a password box would open. She would type in the password and was able to read the file. She has now been replaced with a Windows 7 machine and this is not the case. She is able to open the individual files (without actually knowing the contents) in the directory. The password box will pop up when this occurs. When she tries to access the PDF file from the toc.pdf file she cannot.
    Is there some sort of security permission that is not allowing a pdf file to open a hyperlinked password protected PDF file in Windows 7.
    She is and has been using Adobe Reader X on both machines.
    Thank you.

    I think this may have something to do with your dns settings.  From a shell type ipconfig /flushdns and try again.

  • Sorting DRM copy protected files from an iTunes library

    I want to copy my iTunes library, without picking up the DRM copy protected files.
    Is there a way I can copy the files using a script that will skip the copy protected files?
    Looking at get info the file type is different, unfortunately my scripting skills are remedial.
    Thanks!

    The easiest way to do this doesn't require AppleScript. In iTunes create a new "Smart Playlist". In the dialog that appears, select "Kind" from the first pull down menu, "does not contain" from the second pull down menu, and type "Protected" without the quotes in the text field. This will create a smart playlist of all of your non-DRM items. From there, select all of the items in the playlist and drag them to a folder in the Finder. Might be a long copy but it should do the job.

  • Individually Password protected files from OSX 2.8 not opening in OSX 4.6

    I have a few files that I password protected in OSX2.8 that will not open now in OSX 4.6. The are not part of the vault type protection. It seems that the feature of individually password protecting files in the earlier OSX system do not open, nor give the option to even give the password. In the get info window there is no option to change or type in the password. The password is not related to the administrator password and it seems that it was a feature that did not follow through to the later OSX version. The only alternative I can think of is to install OSX 2 on an external and hope it gives me the option.
    Does anyone know how to deal with this type of individually protected file in OSX 4.6? I have tried the vault, and the get info, but nothing seems to work to even give me the option to enter a password for an individual file. They are jpeg, and QuickTime, and Photoshop .psd files.
    Any ideas?

    Then it's probably not 100%-compatible with the PDF security standard. You
    should post this question on an iText forum.

  • Protecting files from being dowloaded but not from being listened.

    I was wondering if there were any way of protecting audio files on iweb from being downloaded. The only way i found was to auto play file and remove transport bar, is there any other way?
    Thank you.
    David

    Roddy,
    I'll delete your file soon after this message is posted. I only did it to prove my point.
    If the file is served via http and a browser is used to view/listen to it, people can borrow it.
    Your Flash Player format does make the file more difficult to borrow than the QuickTime format found in iWeb. The page design and the Flash Player integration takes only a "few more steps" in the design process.
    Since iWeb uses QuickTime formats it's a bit of a reach to include Flash formats for the average user.
    It may be better for the original poster to protect their page with a password (known visitors), use copyright protection or to add "watermarks" or "DRM" on their files to discourage downloading.
    There's really no method to "protect" anything posted on the Web. If they want it (without paying for it) then posting full quality audio files or videos without watermarks is the best method of discouraging file downloads.

  • Best practices for protecting files from ransomware?

    If you don't know what CryptoWall and such ransomware is, you are lucky. For now.
    This os probably more of a Desktop security issue but I'd like some ideas for file server protection.
    A corporate office got lucky today with just the files on one PC infected and network file shares the user had access to lost - but they were backed up, hence the "lucky".
    But it was scary enough they want to know what Microsoft wants us to do to prevent this in the future. The user was not admin on the local machine and so we are not sure how it was installed (I've read people get it different ways).
    We have SCCM EndPoint protection and obviously it didn't help. It did actually stop a password stealing utility from installing around the same time but didn't stop us from having thousands of files rendered useless for many hours today.
    It was suggested not using mapped network drives but I think one share was hit without a mapping (still waiting for confirmation). But I think anywhere it finds it, ie., under Favorites, could be attacked.
    Suggestions please.
    Thank you!

    You can try this.

  • How do i retrieve file vault protected files from an external hard disk that used to be my mbp's hard drive? the hard disk got corrupted and will no longer boot. I put it in an enclosure and attempted to copy my files but failed because of FV encryption.

    This external hard disk used to serve as the main drive of my mbp. It got corrupted and the OSX would no longer load. I upgraded to a 500gb hd and used the old hd as an external drive. I tried to copy my files but i could not access them because of the filevault encryption. 110gb of hd space appears as used which means that my files are still in the drive. Is there a way to retrieve these files? thanks

    According to your post, you're using Leopard, so FileVault only encrypts your user folder (unlike Lion). On the mounted external drive, in your user folder, you should see a file called username.sparsebundle, with username being your user name. Double-click that file to open it and it should prompt you for a password. Type in your password and the file will mount as a volume in Finder. You should be able to copy all of your files over.

  • Is there a way to protect files from access of the users? (No cxt or dxr method).

    I need to have a lot of files under several directory.
    I need also to allow the projector to access the directory but not for the users..
    I cant' in this case to make an extenal cxt or dxr file.
    Is there e way to prevent the acces to directory, end/or file, by the users?
    Thanks.

    No. The Camera Connection Kit (USB and SD Card adapter) if used for import only. There is no way to save to an external device natively.

  • How do I batch delete all my protected music files from iTunes.

    Hi, in a moment of stupidity, while I was working on a backup folder of my friends files (from his broken computer - copied them to my PC so he could get them back onto his new PC) I managed to copy all of his songs from his iTunes folder into my iTunes library. I don't know how I managed to do this, maybe it was the fact that I was really tired at the time.
    I own all my music - none of my music is copy protected (it is either downloaded from legal sites where the bands themselves [usually unknown or alternative artists] release their music, or I ripped the music from CD's I bought) and all of his music is copy protected.
    Now thing is, I have upgraded my PC before realising I did this, so now I don't have the original iTunes library (formatted PC and reinstalled XP from scratch) - is there any tools out there that will find and delete all your copy protected files from iTunes?
    I could go through song by song and when it comes up with the "Authorise computer - This computer is not authorised to play "******" Would you like to authorise it" and delete those songs, but as this is a very slow and time consuming process and considering I have 8,551 songs, I would prefer a faster way.
    I would go and re-rip all the songs, as I have the original discs, but this would take very long, and put quite a bit of strain on my CD drive, and this would not account for all the songs I have spent years finding on the internet/demo songs from friends bands.
    Any help is appreciated, as I would love to be able to remove all of his songs so they don't keep popping up in my iTunes library
    Thanks in advance.
    Dale.

    I have never tried this and am not at a computer with iTunes, but can you delete from a Smart Playlist? If so, you could make a smart playlist that shows songs that are of kind Protected ACC. Then select all and delete from that playlist. But I am not so sure if you can delete from a smart playlist.
