A problem about digital signature authentication

Hi all:
I just want to know how to implement the digital signature in the adobe form as well as its theroy, processing and the server condition. Please inform me any document available for reference.
Thanks.

The Digital Signature User Guide and Acrobat Security Administration Guide are of particular interest at the location Simon pointed to.

    The best solution for your scenario would be to "Certify" the PDF that you send to your customer.  A certifying signature is a digital signature applied to a PDF (typically by the author of the document).  Adobe partners with various Certificate Authorities that provide "Certified Document Service" credentials.  If a PDF is certified by one of these credentials, the validation on the client side occurs seamlessly with no configuration required on the client as Acrobat and Reader ship with the Adobe Root Certificate installed.
    For more information on the this, check out: http://www.adobe.com/security/partners_cds.html

    and, http://blogs.adobe.com/security/2008/11/livecycle_digital_signatures_t_1.html
    Technically, you could certify a PDF with any credential, but you would need to distribute the certificate (public key) with instructions on how to install it and configure the trust settings in Acrobat or Reader.

  • Problem with Digital Signature strategy in Document Managment System

    Hello ALL,
    I am facing problem with Digital Signature strategy in DMS. If any help its greatly appreciated.
    I have senario where Approvers in DMS will review the document and approve the document and put on their digitial signature. if i have multiple approvers maintained in the characterstics it has to check weather it has been approved by all approvers otherwise it has to reset the status to for approval.
    My problem is i am able to reset the status back from approved to for approval using the badi document_status01 but when the next approver logs in to the document and change the status to approved he is not able to get the digital signature pop up which it comes only first user approves it.
    can any one help me out on whats going wrong in it.
    Thanks
    Srikanth Aduri.

    Hi,
    maybe the reason for this is that the status of the digital signature is not changed. Then the system thinks that the digital signature is still completed and therefore the user is not getting the pop-up again. The database table for the digital signature for documents is TC77. I hope this information is usefull for you.
    Best regards,

  • Digital Signature Authentication

    We have developed a form that requires multiple digital signatures. With each signature, it is forwarded on to the next manager via a submit button and the form attaches to a new email. Last week I updated the form and added a new person's email address to the drop-down menu along with their email address. I extended the rights for users and it seemed to be working beautifully. However, as of late yesterday users were getting a message stating they could not sign and some previous signatures had the ? mark as those signatures could not be authenticated. HELP! I don't know if its a problem with the digital signature or I did or didn't do something??

    Hi Sandi,
    First up, I highly doubt that this is related to the validity of the Reader Extension credential, nor is that something you even need to worry about.
    If one of the signatures is in an unknown state (the question mark icon) then there is a prompt to warn the next signer that they are signing a file with signature problems, but it doesn't prevent signing from occurring. Let's get some background information to help figure this out.
    First up, do you know what application is being used (e.g. Acrobat or Adobe Reader)? Next, what is the version of the application? Finally, this message that users are getting, can you tell me what it says verbatim?
    Thanks,
    Steve

  • Confused about digital signatures

    Please refer to this archived thread:
    http://www.adobeforums.com/webx?128@@.59b4d8d6
    I'm researching digital signatures because we have a request form that was created in Acrobat 7.1, and that a user signed by creating his own signature in Reader 8.x. In Acrobat 7.1, I see a message when the file is opened that it has been digitally signed, and it verifies the signature. I'm trying to figure out whether that signature process would satisfy an auditor as to its authenticity.
    But according to the above thread, I'd need at least Acrobat 8.0 to "enable" a PDF to be signed. What does that mean? The form I received, by all appearances, *was* signed. It didn't need a special signature field... the signature was added over a standard text field and it was recognized and authenticated, and appeared in the signature pane in both Acrobat 7.1 and Reader 8+.
    Also, what does the 500 signature limit mean? By what process is it determined how many times a form has been used and signed? There is no tie, as far as I can see, from one copy of the form to another. The user simply saves a copy, fills it out, and sends it in. Many different people use that form (it's a work request form for IS services). Does the 500 limit apply in this scenario?
    If anyone could please advise and point me toward documentation that would help me understand how all this should work, I'd be deeply grateful.

    >But according to the above thread, I'd need at least Acrobat 8.0 to "enable" a PDF to be signed. What does that mean?
    It means that you need to use Acrobat 8.0 Professional or above to
    prepare a PDF in a special way.
    If this is not done, Reader cannot sign it.
    > The form I received, by all appearances, *was* signed.
    One possibility is that the person who signed it was not clear about
    what software they actually have.
    >
    >Also, what does the 500 signature limit mean?
    The EULA gives the legal details that lawyers would apply. It has
    seemed that each copy used counts towards the 500. If there is ANY
    POSSIBILITY of this limit being reached it is prudent to use Adobe's
    server enabling software instead.

  • Question from worse than Newbie about digital signatures and Adobe Reader.

    1st, thanks for taking the time to even look. 2nd, We are trying to use digital signature pads with PDF documents created by Documaker 11.4. In Adobe Pro there is a setting "Extend features in Adobe Reader" that will allow users with Adobe Reader to sign the PDF documents, however our "guy" creating the forms cannot find anything like this in Documaker. I've never used Documaker before and dont have a copy to even play with, but I was hoping there was a simple "go here, click this" answer.
    Any and all help is greatly appreciated.
    Thanks for you time,
    Jeff Holt

    I'm not expert on Documaker, but I'm close to them and will try to find an answer if I can be sure of the question.
    Documaker is capable of creating PDF signature markers in the output PDF. Those markers are compatible with tools like Acrobat which can sign the documents. Is your question about how to create the markers or are you doing that and finding that Acrobat Reader will not allow you to sign them?
    I'd have to research Adobe's licensing for Acrobat and Reader to see if that was the issue. I know certain features in Acrobat Reader are locked down by Adobe so you have to have another product license from them to enable the feature. If that is the problem, then I'm pretty sure that Documaker has no mechanism to provide a license token to specifically enable the Acrobat Reader product.
    If you can provide more specifics, I'll try to follow up. You may also contact Customer Support, if you haven't already and open a case there requesting a specific question be answered.
    Best Regards.

  • Mac G3 w/ Tiger 10.4.3 update problem/issue "digital signature incorrect"

    I have an old G3 on which I reloaded 10.4.3 yesterday (Retail copy). It did not go very smoothly. This is the 3rd install; 1st install was several months ago with this chip, 2nd install was shortly after that with a PowerLogix chip which didn't work. I put the old chip/processor back in yesterday and reinstalled again. I don't remember if I messed with the firmware or not with the previous installs.
    PowerMacG3, Model 1.1, PowerPC750, 256meg, BootRom 1.1.1f4
    The software updater tells me I need to update to 10.4.8. When I proceed with this, the system downloads the software OK, but when it attempts to install the update I get the following error:
    The update "Mac OS X Update Combined (PowerPC) can't be installed.
    The digital signature for this package is incorrect.
    The package may have been tampered with or corrupted since being signed by "Apple".
    Any ideas as to how I resolve this? Could the problem be with the OS registration, and the different chips?
    Thanks in advance.

    Thank you for replying to my post.
    Yes, I can do a nozzle check with the USB unplugged,
    and I still get poor results on the C82 and nothing
    on the C86. I just can't believe both printers are
    broken. The C86 is new, and they were both working
    fine previously.
    Epsons are notorious for getting their print heads clogged. Run the clean print head routine a few times. If that doesn't work, return the new printer 'cause it's dead out of the box. The old printer, well, once Epson print heads get to a certain level of clogging, nothing will unclog them. Toss the printer and get a new one. Hint: HP and (some) Canon printers put the print heads in the ink cartridges, while Epson and (some) Canons have the print heads in the printers. Machines which have the heads in the carts also have an easy fix for severe clogs: toss the cart. Warning: HP printer drivers stink.
    If you don't need colour, you might think seriously about getting a low-end laser.
    I just got the C82 to print readably, but still
    completely missing magenta and with minimal
    fuzziness. This was just dumb luck though, from
    letting the printer sit idle for several hours.
    It's still clogged. Clean the heads a few times again, or just toss it.
    And yes, I've tried setups through the Print & Fax
    pref pane, which usually works better than going
    through the Printer Setup Utility which tends to
    freeze and crash.
    I wish I could afford to just buy another printer.
    But I'm still worried it's something to do with my
    computer, since both printers are having problems
    simultaneously, and they're both really good
    all-purpose printers.
    It's not your machine. It's Epson.

  • Problems with digital signatures (adobe reader)

         I am a Government contractor that develops documents for my customer.  We are in the process of ascertaining the viability of digital signatures. I have developed a signature form with Adobe Pro 9.0.
         I have several issues. When someone digitally signs the document with their Common Acess Card (CAC), the warning appears "At least one signature has problems. Please fill out the form. If you are the form author, choose distribute form in the forms menu to send it to your recipients."
         I tried using several options using the distribute section, and I am unable to make this part work. I truly need assistance with doing this correctly.  I require that the signatures to be processed in sequence (#1, #2, #3, and then the approval signature).  I did not comprehend that option in the distribute form section.
         However, the recipients that use Adobe Acrobat Pro are able to sign the document when submitted to them (however, the prviously stated warning appears). If they use Adobe Reader, they are not able to sign the document.
         Please help.
         Is there anyone that can assist with the signature feature of Adobe Pro?
         I would appreciate any suggestion/guidance.
         One area that I don't understand is the feature where i 0send the form out for signature.

  • Does any have problem viewing digital signature from PDF?

    I have this problem, when viewing digitally signed PDF from iBooks app, all the signatures are gone.

    I sign the pdf with a digital signature which includes a picture of my written signature.  When I attach it to Apple mail or upload to mobileme, the signiture disappears.  My clients see nothing.  When I go back to the email in the sent box and open the pdf in the email there is no signature.  When I open the original pdf the signature is there
    This problem does not exist in outlook 2011, but would have liked to use mail as outlook does not support caldev
    I don't know if I can explain it any better.

  • Problem with digital signatures in Acrobat 8

    Is it true that the ability to directly create a digital signature field is available in Acrobat 7 & 9 but not in 8?
    I have Acrobat Standard 8.0.0 and want to create blank signature fields before I certify a document, but can't find a way to do this directly. I can add a signature then delete it to create a blank field, but this is a very slow way of doing it.
    I have read Forum articles saying choose Tools > Forms > Digital Signature Tool to create a blank field, but I have no Forms item in my Tools menu. Am I missing something, or do I need to upgrade to Acrobat 9 (or downgrade to 7!)?

    Hi Brian,
    It's not that version 8 per se cannot add a signature field, it's that you cannot create or edit form fields in the Standard version. If you had Acrobat 8 Professional, or you buy Acrobat 9 Pro, then you would have the capability to add and edit form fields (a signature fields is just a special purpose form field).

  • Problem validating digital signature

    Hi!
    When I try to validate a digital signature in Adobe Acrobat, I get two different responses, given the path I choose to validate the signature.
    If I go through "Signatures panel" and check the validity of the certificate that signed the document, it tells me it's OK. If I click directly on the signature, and go through "Signature properties", it tells me the certificate signature can't be verified.
    Can you help me?
    Thanks in advance!
    Mariana

    Which Acrobat version, which OS? Could you, provide screen shots indicating where do you see discrepancy?
    Also, please do the following.
    1. Close and reopen Acrobat. Open your PDF. Look at the Signatures pane and record info in it. Then click on the signature. When you click on the signature it revalidates it and then offers you to open :Signature Properties" dialog. If you cancel this offer and look a the Signatures pane again, does it show the same info as the first time?
    2. Close and reopen Acrobat. Open your PDF. Look at the Signatures pane and record info in it. Right-click on the signature and select "Show Signature Properties". The "Signature Properties" dialog comes up (without revalidating the signature as in #1). Does it say the same as in #1?

  • Question about digital signature

    How I can create digital signature for document by some OAS tool in Java servlet? If yes, then how?

    Excuse me my English.
    Maxim

    you add a signature field to your form --> then watch the properties
    you can define collections of fields to tell the document which fields should be regarded/disabled by signing the document
    ads can check signatures (digital signatures) serverside (methods for the pdf object)
    with signature pads its special, you need hardware (pads) and software (plugins for the reader) and so on...

  • Created a user account for my daughter but itunes will not open, just says something about digital signature policy

    Hi there, newbie here. Wondered if anyone can help, opened another user account for daughter on windows 64, and when we tried to open itunes a message came up saying it could not open because of digital signature policy, when i go back to my user it opens ok.
    Could anyone help.
    Cheers

    am not prepared to enter my credit card also on her account application.
    You can enter it on the registration page then delete it immediately after you complete the registration.
    If I purchase a iTunes card with some credit, can I open the account for her just with the code?
    If you wish. Instead of going to Create new accout, go to Redeem on the main iTunes store screen, enter the code, then select *Create new account*.
    What will happen if the credit on the card gets to zero?
    She will not be able to make a purchase until another gift card is entered or a CC is linked to the account.

  • Questions about digital signatures

    We have about 100 people in our organization all using Acrobat X Pro. We currently sign PDFs (only used internally--we don't sign things to be sent out to customers, vendors, etc.) using the self-signed, self-generated PKS#12 option. This has worked well for us in the past, but we find ourselves having to backup each user's signature in case it gets lost, deleted, hard drive crashes, etc. Is there a more central way to sign documents so our users don't generate their own signatures, email them to other users, etc.? We'd like to use something that can incorporate the users' domain credentials so they don't have to remember a separate password. We're on a 2008 R2 domain. Thanks!

    Eline,
    Yes, you can connect the wireless headphone to the player. Infact you can connect it to any stereo devices with the audio transmitter as long it's using a 3.5mm minijack. It shouldn't be a problem for the audio even if the player is inside the bag. It works about the same way as a mobilephone to a Bluetooth headset. Unfortunately, the Zen Xtra player does not support remote control feature.
