Free invisible digital watermark?

Does Lightroom or Photoshop has some form of invisible watermarking tools? I am looking for a free digital watermark app that doesn't involve visible text or images being placed on the image. I used to use Digimarc when it is free (years ago), but now there are subscription prices, although there is a free plug-in download for Photoshop.
I only want to use it on 2 photos that I am emailing to someone. Does anyone know whether Lightroom can do it? Or know of any such apps?
Thanks!

If such a plug-in exists for Lr the developer is keeping very quiet about it.
This is a link to a earlier thread asking the same question http://forums.adobe.com/message/1396376;jsessionid=FD45A6F5A4EC61B35FC14DFBA586C07B.node0 As you can see there wasn't much help back then either.

Downloading e-pub with digital watermarking protection

Hi all; I always bought e-books for my Nook and successfully downoaded them. The format was e-pub with DRM protection. Downoadings are addressed to 'bought books' directory in Adobe Digital Editions and then they're readable on 'my documents' in my Nook. The last one I bought, was an e-book e-pub with digital watermarking protection. I don't know if different protection is the cause, but this time the downloading is automatically addressed to 'reading now' in ADE. This time the e-book is not in the list of 'bought books' (in ADE). When I disconnect Nook, the book is in 'my documents' list (of Nook), but when I try to open it, I only see the cover for a couple of seconds, and the page is reverted again to 'my documents'.
How to do? I can open it in ADE on my PC, but not on Nook. I'll appreciate any help!

I moved your posting from the Workspaces forum to the Digital Editions forum.

Digital Watermarking

hi,
Searching for help in Digital Watermarking. I hardly find java source code from the web. Hope can get some help here.
if anyone have java source code of digital watermarking, please send me a copy at: [email protected]
thanks a lot

I do not know of any java digital watermarking. There is alot of it being done in C. You would just have to write JNI to get this working. I would also be interested in finding out if there is java digital watermarking being done.
Another solution would be to port the C code to java. I am sure that the JAI libs would help.

Custom Digital Watermark

Is there a way to add a custom digital watermark to a labview front panel? Thanks.

There is a way, but it won't be easy...
You can put a picture control (or a decoration) as top most object. Now,
there is your watermark! Problem is that this watermark will block all mouse
clicks, so everything behind it will be useless.
You'll have to catch mouse clicks on the picture control, and make the
controls behind it behave like they would if you'd clicked them directly.
This will be very difficult, unless you only have one or two boolean buttons
beneath it. For a numeric, you have to give it key focus when click in it,
but also calculate the text position of the cursor, increment and decrement
if that is where the user clicked, and don't forget about dragging the mouse
to select text!
Then you have the transparency problem... You can apply a mask to an image
in the picture control, but it is either on or off. So you have to make it
look transparent, by alpha blending everything behind the VI with the
picture... A hole new set of problems...
You might try to use GDI functions to draw a picture above the VI. In
general, this works poorly, since the objects disappear when LV updates it's
panel. But in this case, it could work. but if it doesn't, you're lost.
I'm not shy about hacking stuff like this, but in this case, I'll pass.
Perhaps if you explain more about your mmi, we could figure out another
clever scheme. For instance, a watermark over a graph area is a lot
easier...
Regards,
Wiebe.

Digital Watermarking on image in frequency domain

I am working on a Project which aims at studying the digital watermarking on image, with both spatial domain and frequency domain.
I have finished the spatial domain but is frustrated with the frequency domain right now. I have no idea on how I can possess the frequency domain of a image. Is there a built-in function which can help us to do so?
Thank you for your help.

I am not able to download the free Adobe Digital Editions in order to view the 2012 Master Tax Guide

Once I tried and got done on the status bar but it was not downloaded. The next time the status bar had error on page. Please advise.

Diana, there's a process to follow here, and there can be some technical
issues as well.
First the technical issues. If you have a Windows PC with Windows 7, you
may need to adjust its security settings to allow the download and also the
interface to the tax guide.
Next, while Digital Editions is free, you need to register with Adobe and
obtain an Adobe ID in order to use it properly with most sites. I'd start
there if you have not done so already.
After you've registered, obtained an Adobe ID and downloaded/installed
Digital Editions, go to the site where the tax guide is to be downloaded
from and try to do that. If you get 'strange' messages, Digital Editions
may be telling you that your security settings need adjustment to allow
downloads from this site.
Hope this helps!

Invisible digital signature acrobat x

is it possible to sign a PDF more than once with a digital signature that is invisible? After one invisible signature is on on the page, the invisible signature command is grayed out.

Hi Jay,
There are a couple of ways to go about this. When you are creating the signature form fields, or even later you can edit them, and set the field to Hidden.
You are looking for this:
Another way is to make the first signature invisible using the Sign > Certify without Visible Signature (version 9) or Tools > Sign & Certify > Without Visible Signature (version x) and then clear the signature from the Signature Navigation Panel. Repeat that process for as many invisible signature fields that you need to create. You could then right mouse click on the invisible field in the Signature Navigation Panel and either sign or certify (with the caveat that a certifying signature must be the first signature and a document can contain only one).
Good luck,
Steve

Request for THE dolby digital answer from Apple

My old set up was component video and optical into AV reciever. All worked well, HD movies had DD 5.1 soundtrack.
Now my new HDMI set up doesn't seem to send 5.1 across.
1. I have dolby digital set to on
2. I played a known DD HD film 'In Bruges' but no matter what could not pick up DD 5.1 via HDMI, my AV reciever Sony 2400ES (brand new model) just piccks up stereo
3. The soundtrack worked beautifully when sent via optical in full DD 5.1
4. I tried to select the 5.1 audio track via play/pause button which seemed like a great solution just in case both stereo and DD 5.1 were being sent via hdmi and confusing amp, but no selection option exists.
what worries me is the lack of response (that I can find) from apple on what as usual seems to be a huge amount of postings on this subject.
What would be handy Apple are:
1. A FREE dolby digital 5.1 movie/tv episode to 'play with' on with a selectable soundtrack option to allow you to check every option on your home cinema set-up without wasting £4-£5 every 48hrs. And I know the start up movie is said to be 5.1 but it lasts for a few seconds!!
2. A definitive answer on this issue
3. A difinitive LIST of movies and their soundtrack options, why does it take the pre buying screen to confirm/deny that the HD movie is indeed in 5.1, can't you use the same nomenclature as years and years worth of DVD covers, PUT Dolby Digital 5.1 and the little 6 speaker logo not just the double D's, which in DVD land usually just denote dolby stereo.
4. some administrator postings, I can't remember (apologies if wrong) seeing OFFICIAL responses in these forums, just loads of confused owners. And I remember a couple of years ago when my 80GB firmware update rendered my ipod dead, and it took WEEKS to find out how to fix it, which was a roll back until the new firmware was released.
I love 720p movies in 5.1 DD via HDMI, or rather I love the idea of them. It seems daft that to get it all as it should be I need to revert to component and optical

{quote}I played a known DD HD film 'In Bruges' but no matter what could not pick up DD 5.1 via HDMI, my AV reciever Sony 2400ES (brand new model) just piccks up stereo{quote}
In Bruges - in 5.1 works fine on my ATV with it connected to my AV receiver via HDMI
{quote}The soundtrack worked beautifully when sent via optical in full DD 5.1{quote}
It seems that your HDMI input on your receiver has not been configured to accept 5.1. You may need to check the settings of the receiver.
{quote}I tried to select the 5.1 audio track via play/pause button which seemed like a great solution just in case both stereo and DD 5.1 were being sent via hdmi and confusing amp, but no selection option exists.{quote}
This option only exists in 2.3 if you have extra audio tracks (e.g Director's Commentary, Alternate Language). If you have the "default" 2 tracks of AAC Stereo and AC3 then the Audio tab does not appear.

However, no matter if it is a few seconds or not it still plays in 5.1. Again, my ATV to my receiver via HDMI flips over to 5.1 when playing the startup movie, back to Stereo when negotiating the menus then back to 5.1 when i play a movie
{quote}2. A definitive answer on this issue{quote}
Would be nice as it has affected a lot of people

I have plenty of DVD's where the Double D logo is shown and then right after it the words: Dolby Digital. Anyway, head on over to www.appletvjunkie.com if you want a list.
{quote:} I love 720p movies in 5.1 DD via HDMI, or rather I love the idea of them. It seems daft that to get it all as it should be I need to revert to component and optical{quote}
Again, no issues here with 5.1 over HDMI. You say you have a brand new receiver - perhaps the settings are not quite right on it to accept 5.1 over HDMI. Just a thought.
I can't see how a "known' film that plays in 5.1 over Optical but does not over HDMI be a problem for Apple. It's not like they can add "Do not send over HDMI" flags.
Yes, there is a big thread on AC3 not working with the 2.3 update, but that is down to the lack of AAC track on peoples own converted movies, and nothing to do with it being sent over Optical or HDMI. I don't believe Apple would be missing the AAC track on a movie they rent.

Multiple logos or watermarks on a photo

I am trying to figure out how to put multiple logos and or watermarks on multiple photos as a batch in CS6 or LR5. I'm pretty sure that LR5 can only do one png at a time. But I am doing shots of local bands and would like to be able to put their logo in one corner and mine in the other. I just don't know how to make it happen on both landscape and portrait style photos. Any help would be nice.
Thank you in advance.
Jared

Hello Jared,
the problem "watermarks" was discussed very often in the Dreamweaver forum (see Dreamweaver support forum).
In addition to Steve's hint, here is the LR forum: Photoshop Lightroom. The LR-"cookbook" finds there Lightroom Help | Using the Watermark Editor
Should we really do that? Thereover there is a wonderful philosophical discussion:
http://webhome.idirect.com/~bowers/copy/copy1.htm.
If you really want to try it, I'll give you here the link to a German website (no problem to adapt the source code) where you can create an alert box:
http://www.6webmaster.com/homepagetools/klicksperre/do.php
And by the way there is the misconception that we can protect our graphics (or videos). With little effort interested people can get to their destination. Under some circumstances it simply is a question of browsers technique.
You will see, that in the end it is still difficult to protect images from unauthorized copying. So you should use best (quote): "To discourage theft, use watermarks, lower quality images and/or digital watermarking like http://www.digimarc.com/digimarc-for-images."

Digital Recorder

Evening everyone.
I have unfortunately had to terminate my mothers subscription to BT broadband and TV due to a berievement. I was told that i would be able to keep the digital recorder. It has never been used as my deceised mother was unable to work it. My question is can the unit be connected to a TV set without subscribing to BT and used as a free standing Digital recorder.
Any advice would be greatly appreciated.
Thanks

If the contract has been terminated early, then you may be asked to return the BT Vision box and hub, otherwise you may be charged for them.
Please check with BT first.
There are some useful help pages here, for BT Broadband customers only, on my personal website.

Digital image protection

What are other togs doing to protect their images online?
Obviously the baby stuff like adding a watermark layer in photoshop is useless and so is the "disabling right click in html" trick. I was wondering more about digital watermark solutions like digimarc provide
Would love to hear everyone else's views
(and apple, seriously you gonna fix the EXIF export bug in 1.1 or what?)

You can spend a huge amount of time and money adding speed-bumps but there really isn't a way to get around the fact that anyone who can see something can copy it (anyone who claims otherwise is at best uninformed). Just think about how much effort the music industry has gone to, how many thousands of lawsuits and the enormous ill-will they've generated simply to get us to the point where original-quality bootlegs are reported to be in circulation within a few minutes of hitting one of the commercial stores.
So - we're basically left with two options: figuring out how to make money without controlled distribution (probably by making it easy for honest people to stay that way by giving them faster and cheaper options) or simply not circulating anything valuable in digital format. It's going to be interesting to see how people combine the two approaches.
