MailXaminer | January 3rd, 2019 | Forensics

Most of the users still get confused between the terms Scanning and OCR. Because both the OCR and the Scanning technologies are used to transform the paper data into digital format. In this article, we are going to explain the complete concept of scanning and OCR technology. Moreover, we will also explain how Scanning is different from OCR documents.

Scanning is the common technology used by the people to convert the hard document into digital data. It is similar to the copy machine, But in scanning technology instead of creating the hard copy it generates the electronic image of the data just like taking an image with Digital camera.

OCR (Optical Character Reader) is another technology used to change the paper document into editable digital data. Even it can be used to convert the scanned data into editable digital data.

Difference Between Scanning & OCR Document

Scanning

  • Scanner generate the Electronic image of the paper document in an uneditable format

  • It reproduces the text data as a digital image with great accuracy

  • It is not possible to generate a text document directly from the scanned image
  • It is secure to share and save the scanned data because of its uneditable nature
  • Not able to copy paste text from the electronic/scanned image

  • Scanned images can be open and view using any type of image viewer

OCR

  • OCR generate the digital document in the editable format through character reading

  • It will easily transfer large amount information from paper to database or electronic records
  • OCR generate digital documents faster than the normal keyboard inputting method
  • Avoid the manual editing errors that occur during the keyboard data entry

  • The accuracy of the document will be less During the conversion of the handwritten or the smudged document

  • Confusion occurs due to the small text or font style leads to errors in the document


After knowing the difference between the OCR and Scanning Document Technology, the question arises how can we find out the OCR file stored in some Document, Mail or File format, as hundreds of Email clients are used by People all over the world. For this situation, an automated solution can be obtained through various Tools.
