Digital signature : how the implement it ?

Hi,
I'm looking for documentation on digital signature on interactive forms.
I've understood that the customer must sign the PDF with a digital signature to prove that the entered data has been added by him. But what kind of signature will it be ? A kind of certificate bought on internet ?
When the customer will send the form back by mail by clicking on submit, how could i check the signature ? Does the customer has to send me the certificate before ? How does my SAP program will check it ?
Thanks

many questions, perhaps you try -->

Need a Suggestion For implementing the Digital Signature For the Documents

Hi,
Currently I am working in a Document Management System. I need a Good Suggestion for how to implement a Digital Signature For the Documents.
Thanks in Advance

Hmm, if you are not using Oracle Payroll, what are you using for payroll? I am wondering why you could not use your payroll system, whatever it is, to handle this reimbursement program.
Well, you may want to talk to Oracle support about how to handle this in Oracle iExpense. You can certainly handle advances for Expense Reports. You would then apply the advance to the expense report items. The catch is I don't think you can stop expense item entry after the adavance is satisfied. You would have to set up a work flow process of some kind to have the expense reports reviewed and only approve expenses that are applied to the advance, is what I am thinking. Not your ideal solution, but something to think about. It could be the Oracle folks might know of a sneaky way to handle this. What you are trying to do is unusual. Employee advances are common, but the idea of not being able to exceed the advance amount is what unusual about this. Normally you will accept any expenses over the advance amount and reimburse the employee for those extra amounts not advanced.
Good luck.

I reinstalled Itunes a couple of times. I unistalled all programs that I never use, I updated all of my drivers, Windows swept my computer and found no problems. I have a yellow causion lite when I look at the USB-port with the phone connected. All other devices work without a problem.

To print Digital signature on the Purchase Order

How to print Digital Signature, on the PO Print copy (PDF).
It will be based on release strategy. Whoever is approving the PO, his signature should be printed automatically on the Purchase Order.
How to achieve this ??
Please let me know in detail
thanks
amit

Hi Amit,
I am not sure on how to get the the signature of the person who released the PO, because as per my understanding the Relase Strategy i.e the Relase code is attached to a Basis profile.
What I would suggest is if you can get all the guys who can release a PO and define him as a Purchaser ie. a Purchasing group then it would be easier to print his signature in the PO.
Here are the Highlevel steps
1. Just have the Signature you want to print in a Tiff format.
2. You can upload the signature as a standard Text using program RSTXLDMC to upload and give a text name.
3. call the text name in your sap scripts.
reward if useful.
Thx,
MJ

Digital signature on the update is missing? So cannot load updates for MacBook or synch Ipad - Help

Digital signature on the update is missing or invalid.This message appeared when trying to up date ITunes in order to Synch with a new IPad.

Wondering how to download from update site? I have 10.6.8 and need to upgrade, do I jump to the most recent version, or to 10.7?
Also, if the automatic update doesn't work, what do I do to use something from the download site?

Digital signature increases the file size

My digital signature increases the file size from 262kb to 15meg. How can I reduce the file size?

Actually, it sounds normal. Try turning off the preference "Include Signature’s Revocation Status When Signing" but be sure you understand the consequences... that space is being used for something that might be important.

Second digital signature invalidates the first one

Hello to all,
I'm having some troubles adding a second digital signature to an already digitally signed PDF. The library that I'm using in order to handle the PDFs is an open source one, so I'm programmatically editing the PDFs. The first PDF I produce, PDF1 (the PDF with one signature), has a valid digital signature. The second PDF I produce, PDF2 (the PDF with the two signatures), has the second signature marked as valid, but the first one as invalid with the following error:
Error during signature verification.
Unexpected byte range values defining scope of signed data.
Details: The signature byte range is invalid
I've read and applied all the "best practices" on PDF digital signature, so I'm adding the second signature in incremental mode and I'm sure that the second PDF has no changes in the first part, this because if I make a binary comparison of PDF1 and PDF2, the first part of the PDF2 equals PDF1. So if you remove the incremental part from PDF2 (after the first %%EOF), you obtain PDF1 again with the valid digital signature. So the problem seems to be in something new in the incremental part of PDF2 that makes Acrobat Reader X thinks that the first digital signature is invalid.
If you want to see the three PDFs, here are the links:
The original PDF: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzrgexS80Iq_ODQxZTY2MDk tNTQyYi00YTE0LTk0MTctYWMxNDFiOWY4MjA5&hl=en_US
PDF1: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzrgexS80Iq_ZDQ3MTk1ZmI tNWI4NS00YzdhLTkxNmUtODk1NjVmY2M2NTVh&hl=en_US
PDF2: https://docs.google.com/viewer?a=v&pid=explorer&chrome=true&srcid=0BzrgexS80Iq_ZGM1YmZhMWE tY2JiYi00YzZkLWE5ZjItNzgwM2RlNzExYWE1&hl=en_US
Any help will be very apreciated. Best regards.

Hi,
I'm not sure if this helps, but I found something unusual with your PDF2. Just at the beginning of the second incremental update (with the new signature), the first object is added without a carriage return. This make the last line of the previous update looks like this:
%%EOF3 0 obj
May this leads to incorrect parsing and then invalidates the signature? Not sure about that, but as far as I can read offsets, your byte ranges are correct.

"digital signature on the update is missing or invalid" 10.6.8 combo 1.1 from 10.6.3.

Also got posted in '10.3 or earlier' community, where other posts are regarding this issue ... I get "digital signature on the update is missing or invalid" trying to install 10.6.8 combo on MacBook currently using 10.6.3. Have used Disk Utility, Restart, Shut Down, with no luck. Used Software Update from 2 different avenues, and also downloaded from apple site. Also searched support.apple, no luck. Thoughts?

ok. i've done the moving of those plist files, restarted and tried again. it hasn't worked, but thank you for your suggestion. i got excited for a minute or two.
it now says An unknown installation error occured. The installer encountered an error that caused the installation to fail. contact the software manufacturer for assistance.

How the implementation differs between BW and BI , Is BI takes more time fo

Hi All,
I would like to know difference between implemenation and time lines for MM as mentioned below.
How the implementation differs between BW and BI , Is BI takes more time for implementing MM module than on BW?

Hi Timo,
Thanks for response!
But as i read from the following url: http://docs.oracle.com/cd/E15051_01/apirefs.1111/e10653/oracle/jbo/ViewObject.html, the setQueryTimeOut(int timeOutMills), the timeOut is mentioned in milliseconds. Please correct me if I am wrong.
and i have overriden the executeQuery() method in the View Object Impl class as shown below:
public void executeQuery() {
Map sessionScope = ADFContext.getCurrent().getSessionScope();
sessionScope.put("MyQuery", this);
try {
super.executeQuery();
} finally {
sessionScope.remove("MyQuery");
throw new JboException("Query Taking too long to respond");
and in the JAVA class i am calling the above method like this:
monitor.setQueryTimeOut(6);
monitor.executeQuery();
But the issue is:
1. The above exception message is getting carried forward to other pages as well. I mean somewhere in the session/ADFContext this message is being saved and error comes up/pops up when i click on other tabs of the page. How do i clear this?
2. The above exception message is coming for the first time but when i click the 'Submit' button second time, i am getting the results and also the message that 'Query is taking too long to respond'. This should not be the case, everytime it should show the same message as the timeout limit is less and the query should end without fetching the results.
Kindly let me know how to resolve the above issues, any pointers will be helpful.
Thanks in advance.

Freetype OR digital signature in the same field?

Hello,
I'm creating a form for someone who wants to be able to use a digital signature OR free type within the same field.
I've tried creating a new combo box with the free type as the first option, but can't seem to figure out a way to have a digital signature as the second option.
Does anyone know if it's possible to get both options in one field?
Thanks in advance.

Thanks, George. You've helped me several times in the past and I know you're a power user, so if you say it's not possible, I know I'm barking up the wrong tree! Appreciate the reply.

"Windows cannot verify the digital signature for the drivers required for this device."

When I connect my iPod to my laptop, it only connects for about 10 seconds before disappearing. If I look at the iPod's properties in the Device Manager, it says:
Windows cannotverify the digital signature for the drivers required for this device. A recenthardware or software change might have installed a file that is signedincorrectly or damaged, or that might be malicious software from an unknownsource. (Code 52)

I would uninstall and reinstall the Apple software. See the following. The following also has a link for Win7/Vista

How can I create a form requesting a digital signature at the end?

I'm looking to create a form for a meeting that allows attendees to fill out their address and pertinent information as an agreement and at the conclusion of the form give them the option to sign electronically/digitally.
How can I do this? Is Adobe Forms the best program for this?

Hi,
Unfortunately, digital signatures are not supported in Adobe FormsCentral.
In order to collect signatures from the attendees, you can either use Adobe EchoSign to collect electronic signatures or Adobe Acrobat to get the documents digitally signed.
Please follow the links to know more about the services:-
Adobe EchoSign:-Electronic Signature Software, Digital Signatures | Adobe EchoSign
Adobe Acrobat:- PDF converter, PDF editor, convert to PDF | Adobe Acrobat XI Pro
