Make a printed digital signature disappear if the document changed

We have created a document and digitally signed.  We then modified the document.  When the document is displayed on the screen the shows signature as invalid.

When the document is printed, however, the signature is the same.

Is there a way of showing the status of the signature (valid / invalid), or what in fact disappear in a printed document?

Note, I have noticed a similar question here, but the response was a link that no longer works.

Thanks for your help.

Here's a good tutorial to add a custom menu item: http://acrobatusers.com/tutorials/2006/add_custom_menu_items

The script that you create in the folder level JavaScript using the method doc.addScript (http://livedocs.adobe.com/acrobat_sdk/9.1/Acrobat9_1_HTMLHelp/JS_API_AcroJS.88.440.html) to add the script to the level of the document for the document. So start writing the scenario at the level of the document that defines the signature does not print if it is not valid. Once you have this work you can use it with the script to the folder level that adds the menu item.

If you're stuck with code, post again and include your script.

  • How to make an electronic digital signature?

    How to create an electronic digital signature?

    @

    If you want to create a digital signature based on certificates, you start to get a digital certificate. If you want to take advantage of the feature complete of digital signatures and then you get a reputable certification authority certificate. If you only want to ensure the integrity of the documents, you can create a certificate self-signed in Acrobat Pro. When you have a certificate add you it to the Acrobat digital IDs. After that you can start to sign your PDF documents using this certificate. In Acrobat XI go you to sign-> work with certificates-> sign the Document. Since version 11.0.7 that adobe Reader can also sign. Earlier versions of Reader requires that PDF is already ready to be signed by its author: includes fields from signature signed and is Reader extended for the signature.

    Make sure that when you get a certificate which is encrypted password, do you remember the password you may need several times.

  • problem with multiple digital signatures by deactivating the fast web view

    Hello, I use acrobat pro 9.1 and have questions regarding a problem with several signatures on a pdf document.

    Why I ask the question below? My job is to prepare PDFs for submission to the FDA. The FDA requires, among other things, the documents submitted electronically have quick view active web.

    I am currently exploring ways to use digital signatures to sign pdf reports and always make sure they are spec FDA compliant. My question concerns a document which would have several signature fields. What I do, it is to create at least two signature fields in the doc and then save and optimize everything for fast web viewing. When I connect the first box and save, the file retains the fast web view state. Yet, when I apply and signatures past one, the file is then left for quick web display with no obvious way to turn it back on. I'm confused as to why it gets disabled after the second, and not just after even the first condition has been signed. And, of course, I would like to know if it is possible to maintain the fast web view and how to do it. I will gladly accept "tinker under the hood' suggestions file if they exist as well.

    Please let me know if something is not clear or you would like more information.

    Thanks for your time and your help.

    Hi Vlad,

    Real Michael has got the right answer. A "Linearized" file (which is a file that has been optimized for fast Web view) aims to get the first page to display as soon as possible so that you can start playing without waiting for the rest of the file to download. Incidentally, the first designated page should not necessarily be page 0 (use of PDF has zero according to the pages counting system), but it usually is. The PDF specification, "the main objective of linearized PDF is optimized PDF documents viewing read-only. It is expected that the linearized PDF generated once and read many times. Incremental update is still permitted, but the PDF is is more linear and subsequently is treated as ordinary PDF. »

    When you open a PDF file the first time that the backup process is a full 'save', it is the whole document is rewritten, so there is no more than two percent markers EOF (end-of-file) inside. The first expressions of folklore means what page to see the first and the second EOF designates the end of the rest of the file (so the browser knows when to stop downloading). However, when you add a second signature (or even longer) the file is saved as a "record growth" and new data is appended to the original file. It is that you can do a restore to the previous signed version and allows Acrobat/Reader verify the integrity of each signature regardless of any other signatures. It's the incremental save, breaking the linear optimization of the file.

  • I don't know any password for the digital signature or the different menu options to remove the same. I need a new digital signature file, or the possibility of placing my signature on a document, as I did for years.

    Remove a digital signature, you need some other password that I do not have. It is clearly not the same as the one I use to connect to this Web site.

    I want to remove the old one and put in a new one, with a new password.  I have Acrobat XI running on a mac with OS 10.10.3.

    Hi Jimster,

    You can create a new without deleting the existing one.

  • Combine several Digital Signatures in a single Document

    I have a document that I send to several people at the same time. I need these people to sign this document at the same time. Once they sign the document, it is sent to me. Makes me to have multiple copies of the same document, but with different signatures. I need to then consolidate these multiple documents into a single document with all the signatures. I tried to make it circulate and then merge the document, but it does not work. Can someone please?

    Hello

    Acrobat does not support parallel signature where several people can sign a single document at the same time. A document can only be signed sequentially where a person sign and then sends it to the next person to sign.  If you have a single document requiring multiple signatures and you need all the signatures on one page, so you have to work with a single copy. However, working with several copies of the document that you are doing now, you could consolidate each copy signed in a portfolio. If for example you have 10 signatures need your file portfolio eventually containing 10 copies signed individually of the same PDF file.

    The key is that you cannot merge files signed into a single pdf.

    I hope this helps.

  • My toolbar Adobe Reader that lets save you, print, e-mail, etc. as the document in the browser window/tab is gone and I want to know how to get it back.

  • OfficeJet 7610 Printer Wizard option disappears from the list of options

    After having initially installing my 7610, clicking the printer from devices and printers would bring a window with an image of the printer up and four options - Assistant printer, see what's printing, set preferences, and customize your printer. Today, there was a message in the upper part of the window indicating there was an update to be applied, so I said to apply. After the update is complete, the window has changed and now there are only three options - Printer Wizard disappeared. It's the same thing with a 6500 printer on my network.

    I use the Printer Wizard to manage all my printers and especially to control scanning. I tried to uninstall all the drivers, then by downloading a new copy of the full of HP and reinstalling software, but the option is still missing. HP did move it somewhere else and not tell anyone?

    What happens when you click on the HP Officejet 7610or 6500 from the desktop or the start menu icon? You can access the HP printer Assistant or you would see any different behavior during the launch of the software?

  • Windows Aero became invalid after installation of my HP printer, it has disappeared from the list of themes.

    Hello, I use Windows Vista Home Premium and since I bought my laptop Windows Aero worked fine on it. However, recently I installed the HP printer software on my laptop and after I finished I opened a Web page explore. When I did that an error has occurred, which I don't remember right now but I'm sure it had to do with the installation of the printer, because it was the first time I came across him and it contained the letter HP. I pressed OK and then the theme is back from Windows Aero to Windows Vista Basic and now I'm stuck here without the possibility of return to Aero. I've been looking around and try different solutions, but nothing worked again. Any help is appreciated, thanks.

    With the display card drivers button to complete an install/uninstall/reinstall is to restart the computer. There is no directive specific beyond what you've already done (remove via the control Panael/programs and Freatures). You just need to restart normally to clear the system before performing the next step.
