Forms and Signatures

My goal is to utilize a Form in order to collect attendance, as well as individual meeting information for activities. A signature needs to be added as validation of the meeting. Is there a way to add a signature collection/ feature at the end of the form? What options do I have for collecting the information easily and ensuring a signature is accepted and stored?

Unfortunately signatures are not a supported field type in Formscentral at this time. You might want to look into Adobe's Echosign product that supports the type of workflow you describe.

Forms and Signatures in Acrobat Reader

I am trying to create a form that can be filled out and signed in Acrobat Reader. I am creating the form in Adobe Pro 9 and have No Security set for the document and have enabled the extended features in Adobe Reader under the 'Advanced' menu. The document security does indicate that signing and filling in forms is 'allowed'.
When the form is then opened in Reader X, when the "Sign" menu is selected, the user is receiving the error message that the document's security settings do not allow for signing of this document and it must be printed.
Does anyone have any idea what I am missing?

Please verify the following:
1. The system date on your machine.
2. The PDF properties post opening the PDF in Adobe Reader. If possible please post as screenshot of the same.
3. If you are getting a panel in Adobe Reader X with the label "Extended".
4. If you are on the latest version of Adobe Reader i.e. 10.1.4.

Using Adobe LiveCycle Designer ES and secure parts of form using signatures.

Hi to all ...
I have upgraded to new LiveCycle Desinger 8.1 few days ago, and still do not know all the new features.
I was requested to develop new LiveCycle Form, but this time it has to be secured by Digital Signatures or what every appropriate method.
The form has exactly 2 sections and 2 Digital Signatures:
1. The first section/part is to be filled by the Staff (let us call him the Authoring Staff).
Any one can fill the first part.
After the first part is signed, the Data Entry on the first part should be locked, and no one on Earth should be able to change the data on the first part. Only the signer of the first part is allowed to update/clear the signature but only and only of the Second part is not yet signed.
The staff should not be allowed to sign the form unless all mandatory fields and other validation logic is statisfied.
Only the Signer of the Form and special authorized staff/group of staff will be allowed to open the form. Let us call them Group01.
2. The second section/part is to be filled by special authorized staff/group (say Group02), they are basicall HR Staff (this is a secret).
The second part can only be filled if the first part is filled and signed by the Authoring Staff.
The second part can be signed only if the validation logic on the second part is true (no errors, and all mandatory fields are filled).
Once the second part is signed, the first part the the second part should be locked, and no one on earth should be able to change anything on the form.
Only the signer of the form should be able to clear the signature of the 2nd part and make any changes requried.
If the 2nd part is signed, the Authoring Staff should not be able to change anything on the form.
*****End of Requirements.*****
I have just started, and I am requested to desing the form and implement the required security in 10 days only.
Can any one please help me ?
I am doing my research now.
Thank you.
Tarek.

Dear Dfoto,
Thank you so much for being so kind to spend the effort and reply back, I though my question was left behind the sun... but now I am very happy in deed.
To be more specific, the Form has 2 parts. The first part "Subform1" any one can fill and sign.
The second part "Subform2", only certain users can fill and sign.
I think I found a very strong lead to my solution, when I was playing with LiveCycle Desinger few days ago.
On the Singature Field Advanced Setting, there is a place you can attach the public part of a certificate (Digital Signature) of any user, one or more.
In this part, you tell LC that only those users "signing parties" can sign the field. I tested it and it worked.
Now, if I can use this feature via JavaScript to find out if the user who is filling the form, can sign this field, then he can fill the form. If he cannot sign the field, then he cannot fill the form. I can do that by setting the "access" property of the Subform. Another solution is that I can prevent the user from hitting the "Submit" button unless he signes the designated Signature Field.
I have another small issue:
I found out that if the Signature field is part of a repeating dynamic Subform, it will not work during run-time. Very bad in deed. While I cannot understand why ?, I tool this as "By Desing" feature.
Now, if the Signature is locking parts of forms which has dynamic content (repeating subforms), it will always show somthing like "Signature is corrupted or form was changed after it was signed".
Is this normal ? Is there a way to control Dynamic Forms using Digital Signatures without such annoying issues ?
Thank you.

Ipad app that will fill in pdf form and capture signature with stylus

Hello. I am looking for an application which will allow me to read, edit and fill out pdf forms AND capture a signature on the pdf form with a stylus. Any help would be greatly appreciated. I currently am using an ipad, second generation.

hullo there, i would personally recommend writepdf, i use this myself and you can do all of the above more or less, you can also create customized signatures and insert them into pdfs. i think what i like even more about writepdf is that you can directly edit docs, anyway, definitely look for it on the app store!

Adobe Interactive Forms and Digital Signature

Adobe Interactive Forms and Digital Signature
Hi, I’ve a question if it works to digital sign interactive PDF documents created by an SAP BPM System? So is it possible just to sign the content, and not the interactive components like layout and buttons e.g.?
Thanks for your help.

serverside or at the client??

We now use Acrobat xi for special active forms we created that include certifications and signature fields, some of the forms are programmed to create other forms, will we have a problem upgrading to DC

We now use Acrobat xi for special active forms we created that include certifications and signature fields, some of the forms are programmed to create other forms, will we have a problem upgrading to DC
Our users use a form template to create other adobe forms with calculated fields, signature fields (using digital signatures)
, and buttons. Will we be able to continue developing these forms if we upgrade to Acrobat DC?

Hi Alex ,
In general ,you would not have any issues and problems moving to Acrobat DC .It has a different user interface and with more enhanced features .
You would be able to develop the kind of forms you are referring to .
You could refer to the following document to get more information about Acrobat DC .

What are the security settings to lock down a form with fillable fields and yet allow someone with Reader to fill in the fields as will as save the form and print it?

What are the security settings to lock down a form with fillable fields and yet allow someone with Reader to fill in the fields as will as save the form and print it?

You want to allow someone to open your document and fill out the form (in the fields you have created), but not change or edit the form, right? Here's the answer - assuming you are using Acrobat Pro and someone will be opening the PDF using at least Acrobat Reader 9 and up:
Tools > Protection > Encrypt < Encrypt with Password
Answer YES to change the security.
A new window opens:
     Do NOT select Document Open (or that will require a password to open the document.)
     Select: Permissions (Check the box next to "Restrict editing and printing of the document.")
     Change the following 2 settings from the drop-down box:
          Printing Allowed: Select High Resolution
          Changes Allowed: Select Commenting, filling in form fields, and signing signature fields
          Leave selected: "Enable text access for screen reader devices for the visually impaired"
          Change Permissions Password (insert a strong password)
          Leave all other settings alone in "Options"
          OK - OK
          Re-enter the Permissions Password (the one you entered above)
          OK - OK
          Save the PDF to apply the security [notice that (SECURED0 will appear after the document title]

Certifying and Locking file Invalidates Certification and Signatures in Acrobat 9.0.0

I am running Adobe Acrobat Professional 9.0.0. After creating a PDF document from within Microsoft Word, and it opens in Adobe Acrobat Professional, I performed the following steps:
Select Forms => Add or Edit Forms.
Select the digital signature tool and create three forms.
Select Close Form Editing.
Right click the first form and select Certify with Visible Signature.
Set Permitted Actions After Signing to Form Fill in and digital signatures.
Select Sign.
Save the document, replacing the original file.
Click on the second field, to sign it, and select sign.
Save the document, replacing the original file.
Click on the third field, to sign it.
Select Lock Document After Signing, and select sign.
Save the document, replacing the original file.
I then find that the certification and the first signature are invalid. Only the last field to be signed is valid. Why is the previous signature and certification invalid? This only appears to occur if I both certify and lock the document when signing the last field. If I view the document in Adobe Reader 9, the result is the same. However, if I view the document in Adobe Reader 8 the certification and all the signatures are valid, as expected.
Any assistance much appreciated.

Thanks for the responses Geo & Atin,
Geo,
Maybe I'm misunderstanding what you're saying, but http://www.adobe.com/devnet/reader/articles/reader_compatibility/readercomp_digitalsignat ures.pdf seems to indicate otherwise. Specifically:
"In Acrobat 9, when additional signatures are applied to a document, the earlier signatures continue to have the Valid status, subject to the certificate validation rules that have been part of Acrobat's signature processing for a number of releases.
In Acrobat 8, all signature appearances except the last one would have changed their status to "Valid with subsequent changes" (green check with a yellow warning triangle) if their certificate was still valid."
So I read this that in neither version should the signature be "invalidated" by simply applying another signature, but in version 8 it showed the triangle warning, and in version 9 nothing would change. Indeed nothing does change in version 9 and it works EXACTLY as described above providing I don't both certify AND lock the document. I still don't understand why just the extra locking step violates the "certificate validation rules".
Atin,
I carried out the steps that you described, and it works thank you. I notice that the lock option is not present when I sign the last field now, but presumably this is because by the time the last field in signed, with the settings you describe the document is effectively fully locked anyhow?
Now my problem is, is there any way of setting up templates of the signature fields laid out in the correct position, with the settings that you describe that I can use repeatably on many documents? I wish to use this function to electronically sign technical drawings which are drawn in a CAD package using a template based title block with 'drawn by', 'checked' and 'approved' fields etc. Each drawing may also have many sheets, each with the same fields in the title block. My concern is that to manually place digital signature fields in these 3 spaces in every title block after creating the PDF's, and then apply the settings you describe before certifying (at 'drawn by') and distributing for sign off at 'checked' and 'approved' is going to be a very time consuming and inefficient process. Am I missing something?
Regards & thanks again,
David.

Adobe form Digital Signatures

Hello SDN,
I have to implement Digital signatures in my Webdynpro interactive forms. In sdn I found one example related to online Interactive form security but for offline I couldnt find.
In offline scenario, a user will send pdf form to customer or employee etc to fill the form and send it back.
1) Here how a receiver will know that he got the form, from an authorized person?
2) Once the form is filled and send it back, how receiver can validate whether the filled form came from an authorized person?
3) Also how exactly I can use digital signatures? what are the technical requirements for implementing digital signatures?
4) For implementing digital certificates do I need to have SSL configured for my j2ee?
Can some one guide me on this?
Appreciate your help.
With regards,
Ravi.D

Hi Ravi,
I am impleting a similar scenario.
Can you please let me know the link to the example of an Online Interactive form with digital signatures.
Thanks,

Locking "Clea Form" with signatures

I've created a fillable form and have inserted 3 sections. At the end of section one an employee is required to add their signature. In that signature box property I have set it so that once the signature is applied all form fields selected become read only. The form is then passed onto the next employee to fill out section two and I don't want them to be able to edit the first section of the record. etc. The final signature in section three should lock all form fields.
These signatures lock the fields from being able to be edited, however it's kind of pointless when anybody after signing the document can hit "Clear Form" and all the form fields are removed - hence leaving me with a document that contains no records, just signtaures.
How can I prevent the use of "Clear Form" from being used?

Hi,
If you choose to host your site on Business catalyst, then you can add the file attachment uploader button to your form depending on your site plan. For signatures, there isn't really an option to add signatures. However, you can add a check box button to the form in BC and serve it as the "I accept to terms and conditions" or something like that. You can make it a mandatory field to enforce the submitter's consent.
Hope this helps.

Aish

Forms, digital signatures, cross platform issues

I am trying to implement pdf forms in an educational environment to utilize digital signatures and reduce paper. The form data does not need to go anywhere. It just stays in the form at this point. Some people on campus have Windows machines, others have Macs. All the Windows machines have Acrobat Pro installed and not Reader. The Mac people are more likely to have Reader. There have been problems with emailing these forms between platforms. Does anyone have any ideas about how to solve this? My IT department will not support Reader on Windows machines, so the forms have to work in Acrobat and Reader! How should the orginal document I put online be saved to work in both programs and platforms? What direction should I give the users about how to save the forms they fill out and sign? I've looked all over for this kind of info, but can't seem to find it. Any and all help is greatly appreciated. FYI, I am not an IT person. Thanks!!!

For Mac users, it will be important that they don't use the Preview application to work with the forms. Preview is the default Mac PDF viewer out of the box, and it corrupts PDF forms when it saves them, so it really needs to be avoided.
In order for Reader to save a filled-in form and apply digital signatures, the forms need to be Reader-enabled, which can be done with Acrobat Pro. Acrobat Standard can Reader-enable documents too, but it doesn't apply the digital signature usage right.
The problem with this is if you will be getting the forms returned to you, you can only use data from no more than 500 instances for the form, including hardcopies. This is an Acrobat License Agreement restriction. If they won't be returned, there won't be a problem. Also, the Acrobat users don't need to use a Reader-enabled version, so you can collect all the forms you want from them.
Email will be most reliable if the user manually attaches the file to an email, as opposed to setting up a button on the forms to submit to an email address. You'll find many threads here discussing the emailing difficulties with forms that are set up this way. The problems can be minimized with user education, as the manual process is available in either case. A submit button provides convenience, unless it doesn't work, and it won't for some users.

Problems with Apple Preview filled forms and compatibility with Windows?

Anyone else having problems with Apple Preview filled out forms and compatibility with Microsoft Windows after Lion?
I've had it happen recently with two different people, where the data I had entered on a fillable PDF form could not be seen by Microsoft Windows, but I saw my data just fine.
I don't know what version of Adobe Acrobat they were running.
Thanks,
kt

You will get that first message when the document has been changed in a way that invalidates the internal digital signature that's applied when a document is Reader-enabled. Certain changes are allowed (e.g., filling fields, commenting, signing) and will not invalidate the signature, but others are not. The exact cause of the change is often hard to track down, but it can be due to font problems, some type of file corruption, or something that Acrobat/Reader attempts to correct when the file is opened/saved. You will also get the message if the users system time is not correct and is currently set to some time before the document was Reader-enabled. It seems best to use the most recent version of Acrobat to enabled the documents and recent versions of Reader to work with them.
It problem is probably not related to the user using anything in the Sign pane.

Submitting information on Form and then forwarding the form

I am attempting to automate a process which requires filling out a form and then submitting to a team lead for approval.
Currently a configurator submits a hare copy of a request to enhance code or table.
I want to automate so that configurator loga into portal fills out form and then submits. The request is filled out and submitted via portal to approval authority.
Do I use ADS with portal via Visual composer or some other tool.
Thanks

Hi,
I am also trying to to do something similar . As from Ottos's reply I understand that the second WDA (Approvers screen) will also have a Interactive Form which is created based on data that was stored on the first screen.
Apart from the data, is there a way to make all attrributes of a form persistent so that we can use this to generate the PDF form when ever needed ?
Reason I am asking is because, apart from the data I may have to capcture signature etc., on the form.
Thanks,
Arpitha.

here is a code from
http://www.exampledepot.com/egs/java.security/GetKeyFromKs.html
This example retrieves from a keystore, the private and public key associated with an alias.
private and public key are having the same alias ?
i know a alias for my key but i believe thats for private key not for public key ......is it true that both private and public key have the same alias ?
and KeyPair is an interface and so its difficult to get a key out of it
public KeyPair getPrivateKey(KeyStore keystore, String alias, char[] password) {
        try {
            // Get private key
            Key key = keystore.getKey(alias, password);
            if (key instanceof PrivateKey) {
                // Get certificate of public key
                java.security.cert.Certificate cert = keystore.getCertificate(alias);
                // Get public key

Dynamic xfa form - digital signature becomes invalid

Greetings forum,
I have question regarding dynamic xfa forms and hope, that you can help me.
I filled a pdf form based on a dynamic xfa form (with extended rights for Reader user) using iText. When the content of the PDF is changed, the digital signature becomes unvalid, so that the rights are no longer vaild.
Therefore Adobe Reader (9.0) does not save the PDF. I get the following error message:
"This document contained certain rights to enable special features in Adobe Reader. The document has been changed since it was created and these rights are no longer valid. Please contact the author for the original version of this document."
I tried the following workaround with itext:
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(RESULT), '\0', true);
(http://1t3xt.info/tutorials/faq.php?branch=faq.itext&node=enabled_form),
but I doesn't seem to work.
As a result, the rights are valid but the content of the PDF wasn't changed.
Is there any workaround for that or does it only work static xfa forms/acroforms?
Many thanks for you support!
Irina2000

Sounds like you tried to fill in a form using Acrobat without the form feature use. Actually iText from what I can see is not using Acrobat, but a third party product. To fill in the form, you simply use the hand tool to move over a form field where the tool will change to an Ibeam or similar pointer tool. Select the field and type in the data. That should not make any changes to the PDF in the sense that has been stated. I have no clue where iText comes into the picture.
