Issue while Reading Secured PDF

We are trying to automate a process where we need to read a pdf and capture its data.

  1. While opening the pdf file we are getting the dialogue box where we need to put the credentials (Username and Password both).
    
  2. Read PDF activity doesn’t have any option to put UserName, we can only put password over there.
    
  3. While opening the pdf manually , and putting the UserName and Password and copying the pdf text , the text is encrypted, So we can’t use read pdf activity at all.
    
  4. We are also getting issues while reading the texts using OCR as all the text are not coming in a single page and if we want to see the data in a single page we have to reduce the zoom factor, while doing so OCR is returning wrong values. 
    

Please share your suggestions , how to get rid of these issues.
