It isn't random but entirely normal for PDFs, especially sensitive personal ones, to be made this way automatically. The bank support staff aren't even likely to be aware.
When I contact the bank again, is there some setting in the PDF print driver that I could point the IT Techs to, where such security settings would be automatically (by default) made?
At this point, I can only assume that they are using an Adobe PDF driver.
They won't be using a print driver, they will be using an automated system deep in the bank's specialist systems. It is probably built in. But the techs you speak to won't be programmers who can look at or change anything. You are not going to get them to take off the security.
When I check document properties of the PDF Statement -
PDF producer : Actuate Content Services Document Transform - 5.0.00
PDF version = 1.5 (Acrobat 6.x)
Could this be an outdated PDF driver?
When I create PDFs on my computer, the document properties are:
PDF producer: Acrobat Distiller 10.1.10 (windows)
PDF version = 16. (Acrobat 7.x)
I'm not sure what more we can say to you. You clearly don't want these files to have security, but they do.
Thanks for your input - I will have another go at them tomorrow.. seems like talking to a brick wall!!
I repeat, you will not get through to anyone who will do anything about that. Someone made the decision to put security on your statements. It seems they originally did it wrong, so you could take off the security. Now they have fixed it.
