Digital signature all pages

How I can put a digital signature on every page?
For example I have a 10-sheet document and want to put the digital signature appears once in all the leaves.
Only one signature and you really are signed all the pages (so visible in all pages).
Do I need another software? ¿What?
Is it only can be done with scripting? A few examples?
PS: I have Adobe Acrobat Pro X
Thanks.

Yes, I need a digital signature field on every page, but exactly the same digital signature on every page. Impossible?
Document signed on all pages with the same digital signature

Digital Signatures per page rather than per document

I am looking for some type of solution allowing for digital signatures for pdf files using a certificate authority.
These documents will have signatures on each page.
Am looking for a solution which would be able to validate on a page-by-page basis rather than the entire document.
For example, if we had 10 pages with one signature on each page, and page 7 was changed, would only expect that the signature on page 7 be validated when making changes and not forcing the signatures on all the other 9 pages to be resigned.
Is anyone aware of such a solution?

I have a similar problem. Firstly, I understand the "flawed" comment above but reality is flawed.
I have a number of documents in excess of 1000 pages which I am attempting to manage digitally. However, they need to be available for inspection by my regulator who still requires a paper format. I would like to be able to print, (or have my regulator print), the digitally signed document but still have something, even a small code or watermark, that would be printed on each page to tie the paper to the digital signature on the front of the document.
Is there such a feature?

Digital Signature crashes Acrobat 9 Pro

An error occurs when trying to Sign any PDF document, even when opening a very simple, one word (Times New Roman text only) PDF document. After opening the PDF in Acrobat Pro (WinXP Pro SP3), selecting Sign, Sign Document, Acrobat allows proper placement of the signature box, and accepts the password for the selected Signature ID. When <Sign> is then selected, Acrobat offers to save the document, and when the save location (any location) is selected, Acrobat returns the error below.
Adobe Acrobat 9.3 has encountered a problem and needs to close. We are sorry for the inconvenience.
Error Signature
AppName: acrobat.exe AppVer: 9.3.2.163 ModName: acrobat.dll
ModVer: 9.3.2.163 Offset: 00135fb9
The same source PDF document can be modified, or password protected, and then saved without a problem. Only when a digital signature is applied does the error occur. Acrobat has successfully Signed and saved documents on this PC previously, but starting experiencing this error about week ago. I have uninstalled Acrobat, reinstalled ver. 9.0 and applied the two updates to 9.3.2, and have generated new Digital Signatures, all with the same resulting error when signing a document. The new, signed PDF document is actually created, and a Digital Signature is found in the document, but is invalid, reporting:
Error during signature verification.
Signature contains incorrect, unrecognized, corrupted or suspicious data.
Support Information: SigDict /Contents illegal data
I have tried the troubleshooting steps in http://kb2.adobe.com/cps/403/kb403613.html, but without any progress; the error continues to remain. Any advice on how to resolve this will be greatly appreciated. Thanks.

Hi Mike,
After the Save As operation was done, did you see the signature appearance displayed in the signed signature field before you closed the doc? And if did see the signature appearance, did you happen to notice if there was a green check mark displayed in the blue message bar at the top of the file?
Thanks,
Steve

Can I bring digital Signatures and with a page when I extract it?

I have a client who is adding their own digital signature to documents after reading them. Our current methodology involves extracting the page with the signature and adding said page to another adobe document for our records. However, the digital signature never follows. I am thinking this is by design, but I cannot find unequivocal confirmation. Does anyone have documentation or knowledge on this topic that will clearly state whether digital signatures cannot be copied when extracting pages, or if it can. Of course, if they can, I would also like to know how. Thank you very much.
Eric

You are correct that this is by design. A digital signature provides an assurance about the entire contents of the document, not just the page that it is on (e.g., the signature field is on the last page of the contract, but the signature covers the entire contract).
Extracting just the page with signature would never leave you with a valid signature because all the other bytes of the file would be missing so the signature would not validate.
If you want a validatable record of the signature, you will need to save the entire document. If all you really need is an informal, non-verifiable record, you could try printing the page with the signature to another PDF file which should show what the page looks like. But that is all you'd have so make sure that meets the legal requirements of your situations.

Digital Signatures getting lost when page presence set to hidden

HI All,
My project uses a multi page PDF which has signature fields in different pages. Because of performance issues i am showing only one page at a time and using navigation buttons to browse through pages. So when the PDF loads it displays Page1 and i sign the Digital Signature field and Click the next button which has event like
Page2.presence="visible";
Page1.presensce ="hidden";
Now page2 is visible and if i move back to the Page1, the digital signatures are lost.
But if i dont click the button , and save the PDF, the signature field is retained.
I am not sure how can i retain the signature in this scenario
Any help on this greatly appreciated.
Thanks in advance.

What viewer are you using for showing the PDF?

Visible digital signature on different pages

We assemble closing documents which individually require a visible digital signature. We would like our client to sign only once the pdf document containg all such documents (resolutions, receipts, agreements, notices, etc) but have the visible digital signature show up at the various pages that require signer's approval. Is there a way to have such signature place holders preconfigured for a specific signatory that only signs (electronically) once the document ? If so, is it also possible to have mutliple signatories with multiple place holders in a lenghty document ? I use Adobe Pro 9.2.
Thank you in advance.

This is a common question, but I'm afraid it's almost certainly the wrong question. It usually comes from trying to translate a system of paper signatures into digital signatures without really examining how different they are.
The key is that digital signatures always, without exception, apply to the whole document. Yes, they might have an appearance on one page, but that is of no importance - in fact I think appearances should be banned because they lead people into the trap of looking at the page to see if it is signed - but this is trivial to fake, and of no security value.
If you have a need to overlap a paper based and digital system, you could use a stamp (not a signature) on each page, THEN sign.

How do I delete all existing digital signatures in Adobe Acrobat?

There must be a way to do it. Can anyone assist? Thank you.

Thanks so much for the detailed explanation!
Let me give a little more detail and better explanation of what I have done.
1.      I digitally signed (with a digital id” I had created) a document to be filed with an agency.
2.      This “signature” ( digital id) had information that included my name, time, date and an acrobat watermark in red.
Essentially typed information that proved the document came from my computer (me?).
3.      I was informed that I would have to sign in ink, scan to PDF, and upload it to them, or
4.      Create a “digital signature” that had my name, address, phone, fax, email, etc., and upload that to them.
5.      I tried to create such a digital signature (after reading your email perhaps I was off base a bit) without success- the place I was attempting this using “PKCS#12 digital ID File” but it allowed only limited information to be input and required a password.
6.      I then deleted my old digital id in “security settings” in order to again try to create a new digital “signature” using the “PKCS#12 digital ID File” format.
7.      I now am still attempting to create a new digital “signature” and when I get to the last set up page for the “PKCS#12 digital ID File” (where it asks for a file location and password “for your new digital ID file”), by selecting “add digital id” and hit the bullet for “a new digital id I want to create now.” In the last page of these creation pages there is a “file name” box and a “password” box.
I think this is asking for my forgotten password which I cannot remember. If it was asking for a new password, I recall two password boxes to insure the password it typed correctly.
So I am stuck, I cannot create a new “digital id” which I thought was a digital “signature” and have deleted my old digital id.
In the past I have use a scanned “signature” as in read below but became afraid it could be manipulated in some fashion in important documents and that is why I started using the digital id in Acrobat X, which I thought was a digital “signature”.
So, how far off base am I? What do I do now that I have deleted my digital id in security settings?
Thanks so much for your help.

Digitally Sign All Signature Fields in the Active Document

I have a script which will sign a single digital signature field by the field name.
I need to revise the script so it will sign multiple/all signature fields in the active document without having to put the field name in the script, as the field names will vary with each document.
Can anyone please advise how to modify the script to sign all fields in the active document regardless of the field name?
function myOtherTrustedFunction()
app.beginPriv();
// Get and login to security handler
var oSigHdlr = security.getHandler( "Adobe.PPKLite" );
oSigHdlr.login( "123","/c/Documents and Settings/name/Application Data/Adobe/Acrobat/10.0/Security/FirstNameLastName.pfx");
// Setup Signing Properties
var chk = this.getField("Checked");
if (chk != null) {
// Apply Signature and save back to original file
var bRtn = chk.signatureSign({oSig:oSigHdlr, bUI:false, oInfo:{password:"123"}});
app.endPriv();
Any assistance will be most appreciated.

Thank you for your help, the script will now count only the signature fields which have not been signed.
I have added the second part of the script to then sign all of the blank signature fields.
The script is only signing one of the digital signature fields instead of all of the blank signature fields.
Can you please advise how I can modify the script to sign all of the blank signature fields?
var count = 0;
for (var i = 0; i < numFields; i++) {
    // Get the current field object
    f = getField(getNthFieldName(i));
    // If it's a signature field and not already signed, increment counter
    if (f.type === "signature" && !f.value) {
        count++;
var myEngine = security.getHandler( "Adobe.PPKLite" );
myEngine.login( "123", c/Documents and Settings/name/Application Data/Adobe/Acrobat/10.0/Security/FirstNameLastName.pfx" );
// Sign the field
f.signatureSign( myEngine,{password: "123"});

Adding Digital Signature Fields to Multiple Pages in a Document

Hello,
I have a batch processing java script which will place digital signature fields in a drawing.
Sometimes the drawing could have multiple pages and the script needs to place the digital signature fields onto each page.
The problem with the script I have is that the digital signature fields are only appearing on the first page.
Can anyone please provide assistance with modifying my script so that the digital signature fields appear on every page?
// Drawing signature field rev 0
var numpages = this.numPages;
for (var i=0; i < numpages; i++) {
var a = this.addField("Checked", "signature", i, [1783, 174, 1724, 198]);
var b = this.addField("Designed", "signature", i, [1783, 149.5, 1724, 173.5]);
var c = this.addField("Design App", "signature", i, [1783, 125, 1724, 149]);
var d = this.addField("Proj App", "signature", i, [1783, 101, 1724, 125]);
Thanks very much.

Just index the field names:
var numpages = this.numPages;
for (var i=0; i < numpages; i++) {
var a = this.addField("Checked"+i, "signature", i, [1783, 174, 1724, 198]);
var b = this.addField("Designed"+i, "signature", i, [1783, 149.5, 1724, 173.5]);
var c = this.addField("Design App"+i, "signature", i, [1783, 125, 1724, 149]);
var d = this.addField("Proj App"+i, "signature", i, [1783, 101, 1724, 125]);
Tho there's no point in signing each page in the same document, tho I also see engineering folk do this. They just love signing every data sheet.
And the result will not be good. Each signature will cause a problem/alert for the previous signatures.
Care to indicate your engineering company?

Print pages with digital signatures

My printer refuses to print any page that contains a digital signature. This is true of MS .doc as well as .pdf. Anybody know why?

Google is your friend.
You could also make your frame on a master page.

Cannot insert pages into PDFs after signed with a digital signature in adobe 9

Is there any workaround that allows me to insert additional pages into a SIGNED pdf?
Background:
Author of a form create a form that needs multiple signatures and pages appended and converts to PDF for signing. Person 1 signs it, and sends it to person 2. Person 2 needs to include additional documentation and inserts the pages before signing.
In the new version, I noticed that it changes the document security which may prevent the insert after you sign it. How do I disable this?

Hi Bob,
You may not like the answer, but it cannot be disabled. In previous versions, when you added a page it invalidated the signature. Starting with Acrobat 9, once the PDF file is signed you can no longer make changes that effect the content of the core PDF. The change was made to protect the integrity of the signature. You can still add comments, but (without getting too geeky) comments are not part of the core PDF like pages are, they live in a separate level. Also, you can still add form data, but like comments, what you type into a form field is not part of the core PDF.
The bottom line is, we made the change to protect the integrity of the signture, and the signature protects the integrity of the document. Thus, changes to the document are no longer allowed in signed files.

How (if at all) can Portal be used with Digital Signatures

We are looking at how to handle a web based Digital Signature/Digital Certificate application. If it was simply client/server the answer is pretty clear using OAS and the "Wallet Manager" on the client side.
Now, we have a potentially vast number of users who might logically use the web to access and submit information requiring a digital signature. Since they could be any where, we can't be in the business of handing out their certs, but we will have to be able to accept their certs. I'm glossing over the details here.

Multiple digital signatures in one file

I have a client who wants me to combine 4 different forms into one--then--require a digital signature by the same person after each independent form. So that would be 4 digital signatures total. And all identical. I'm using a different name per each field so there's no conflict.
It appears to work fine until I have it submit dynamically with a PHP script via email inbox.
When I open the PDF (having crunched the info back in from an FDF) the data is there EXCEPT the digital signatures.
Can someone point me to a tutorial?
Best regards,
Mare

Hi Mare,
You cannot merge files and expect that the digital signatures will be preserved. When you sign a file you are signing all of the bytes in that file, and only that file. Once you combine files you are creating a new unsigned file. If someone were to sign the new file they are signing all of the bytes in the new file, not just some of the bytes. There is no "page level" signing in PDF files, only whole file signing.
You can however put the signed files into a Portfolio file. A Portfolio keeps the files separate. Think of a Portfolio like a file cabinet in the physical world. Just because you put different files into the file cabinet drawer, they don't merge.
