Creating multiple digital signatures

When I create multiple freehand signatures in an adobe acrobat document there is an issue.
Can I create multiple signatures and place them on the document without having the original signature be listed as part of an older revision? It marks a new signature as a change to the document and creates a second revision.

>As a business process when would people be approving the other's signatures?
As a normal business process maybe not. But consider: a signature can
have a visual aspect. This visual aspect might be large and not just
an written name: so someone could be tricked into signing something
different than the original document, maybe.
Anyway, this is moot. The signature becomes a part of the PDF. Each
signature certifies the entire PDF, not what a document looks like,
but byte for byte everything in the PDF, whether you can see it or
not. Hence, each signature encapsulates the previous signatures.

Multiple Digital Signatures on single profile.

Hello,
I have a question. Can I create multiple digital signatures on a single system.
If Yes, I can create digital signature of any "Signature required person" and I can sign for him, If I have his email id and Organization name, correct?
It means we can easily sign for any other person in the world. If so, how does this system mean to be safe ?
Thanks

Please repost this issue in Acrobat forum.This is reader forum.

Creating Documents to Support Multiple Digital Signatures

I am currently working on creating a paperless business process utilizing Adobe Acrobat's Digital Signature Feature. However, I'm having a lot of problems utilizing it.
Can somebody please explain the entire process from document creation in Word to creating the digital signature fields to distributing the document and receiving signed versions back?
Also, how can I enable this feature so coworkers with Adobe Reader can sign and send back to me?
Thank you very much,
Jeff

A tip: if you want "multiple signatures" to mirror a paper workflow
where someone signs a document in more than one place, this does not
fly in PDF. In PDF, a person does not sign the same document more than
once (except perhaps to countersign after they signed, then someone
else changed).
Also bear in mind that if you have the idea that you will send out a
document, that it will be signed separately by multiple people, then
you will merge the signatures back into a single document, that this
flies even less well.

How to do Multiple digital signatures?

I have created a form in Acrobat 9 Pro with multiple digital signatures. This is an approval form that is emailed "up the chain of command". I have enabled extended features in Adobe Reader so that users without Acrobat 9 can digitally sign the form. I created the form and did a certified signature. I then emailed it to a typical user who filled in the form and emailed it to her boss for a digital signature. Her boss digitally signed it and emailed it to the CFO. The CFO does not have Acrobat 9. When she gets it, she gets the error message "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document." How do I correct this?

Steve,
I wanted to test how cumbersome it would be to have the 2 staff members open with Adobe Reader instead of Creative Suite; however, I have not been able to find any option like "open with" in my outlook email. Every time I try to open it defaults to my Acrobat 9 Pro to open the document. Would the 2 staff members have to save the email and then use "open with" in order to by pass Creative Suite?
Also I am not sure if you answered my question last time - Is it possible to just upgrade the Acrobat portion of Creative Suite or do you have to upgrade the entire Creative Suite just to get the newer Acrobat? I will also be checking the upgrade link you sent. Thanks.

Form Size issue with multiple Digital Signatures

I have created a form (liveCycle 8) with multiple digital signatures required. When each user signs the form, that section of the form is locked using collections. The form is workflow through email after each user signs it. Each time the user signs and forwards the form, the form's size becomes too large.
How can the form be optimized to compress each time an users signs the form?
Thank you,
Lori

Steve,
After your request to post the form, I wanted to removal some company items like the Logo. Once I removed the Logo, I found the biggest issue was a Logo image size that was making the file so large. Once I reduced the image size, the signatures only added 46kb at each signature level.
Thank you for your help,
Lori

How do I create a digital signature on a TCP or a UDP flow?

I am trying to convert samples of a voice signal, which is intercepted from the microphone, into fixed length digital signature bytes (using Hash, or) and attach these fixed length bytes to a communication session between two terminals (UDP or TCP "HTTP"). The other receving end should be able to identify the person at the sending side.
Any thoughts how I could do this?
Any help is most appreciated.
Sam

Sam,
If you have the Sound and Vibration toolkit it may make some things easier for you regarding the voice-recording aspect, but if you aren't recording and playing back the actual sounds, just using this for detection and digital signatures, you shouldn't need to worry about this.
1. For this you are going to be doing some form of Analog Input. Then you will be storing this data to a file. There are examples for both of these aspects in the NI Example Finder from within LabVIEW.
2. If you are going to be doing the FFT, there is a VI under the Mathematics Palette that performs this operation. Again you can use the same example for saving data to the file.
3. You would need to figure out what needs to be done to create a digital signature for this. There may be something in the Sound and Vibration toolkit for this, but I do not know.
4. For the UDP or TCP transfers, there are several examples for doing this and they cover how to create the connection and transfer / receive data. These too are in the NI Example Finder
5. This goes back to number 4, this would indeed be a separate program, but everything else would just be one project and one program.
6. This would depend on how the ID was created in step 3, again whether you do the algorithm on yourself or not. For comparing to the table, you would use a Search Array and some comparison functions, all depending on how you stored the data initially.
7. Graphs are all available on your Front Panel of your VIs and you would just wire up the data that you'd like and have it displayed on the graph.
There will not be an example for everything that you are wanting to do. The examples are meant to help you get started. Have you used LabVIEW before? I would recommend doing the 3 Hour LabVIEW Introduction Course to help you get started. This will cover some of the basic concepts that you will need to know in order to create your application.
Unfortunately I cannot write the code for you, only guide and direct you. LabVIEW is a programming language and does require the user to lay out and create their own program. You will not be able to just find three or four pre-built code-snippets and connect them together to get your appliction working the way you want it. You will need to develop the applications yourself.

In Adobe X Pro, how do I create a digital signature in my document so that my receiver is able to sign it electronically.

In Adobe X Pro, how do I create a digital signature in my document so that my receiver is able to sign it electronically.

If the other person will be using Reader, you should first add a digital signature field and then Reader enable the form. In Acrobat 10 you'd select: Tools > Forms > Edit
to get into form editing mode. You'd then select the signature field tool to add a signature field.
Once you have the document finalized, Reader-enable the document by selecting: File > Save As > Reader-Extended PDF > Enable Additional Features
being sure to save to a new file so you don't overwrite the original. If you don't Reader-enable, Reader users won't be able to digitally sign.

Pdf fillable form - multiple digital signatures

I have a fillable pdf form that requires multiple digital signatures. Is there a way to send the form to multiple parties and merge it back to one form upon receipt of the signature from each party? Does that be accomplished with a javascript or do I need to use a different software? Thank you.

That's not how digital signatures work, so the answer is "no". When multiple people need to sign a document, they need to sign the same document in sequence.

Create electronic-digital signature for data

Hello
As possible create electronic-digital signature for data, referred through HTTP form internet explorer?
Thank you very much for your support.

George,
Thank you for your submission. It was helpful. This allowed me to create the signature block without having to place my own digital signature in the block. However, when I send it to my client (who has Adobe Reader but not Acrobat) she is unable to input her digital signature … I’m now half-way there but I continue to pursue a solution.

How to create a digital signature error

Hello,
hope i do my post in the right forum (if not i'd be grateful if it could be displaced to the correct forum). I've to do create some incidents to have a look at the output of Security Audit Log (Transaction sm20).
I want to create a digital signature error (SAL Identifier AUV) and i've no clue how i could get it done. First I thought about an invalid single sign on ticket but apart from I would have no clue about how to create such, I don't know if that's a way to make the error, mentioned above, occur.
Maybe you could give me a hint or you have an idea how I could get that done!?
Thanks in advance
Tobias

I was able to create a digital signature for someone else and use it. How is that protected??

I was able to create a digital signature for my boss who's on vacation using his email address. I figured when I used the signature he would get some sort of email confirmation letting him know, but he got nothing. So it seems like I could create a signature for anyone and use it on any document without their knowledge. What's the protection against anyone creating a signature for anyone else and using it whenever?? Am I missing something??

A digital signature can not be used to verify someone's identity. I can create a signature using anyone's name and email address. In fact, those things are irrelevant to the signature. The only thing that matters is the key used to create it, and therefore to verify it.
