Compare Documents Functionality

In the most cases it is safe to assume that a document and its copy are containing the absolutelly same information.

But it is really the case? Or are there any differences - and in such a case, wouldn't be important to find them very quickly?

In many situations it is of significant importancy to assure, that the content of a document is 100% identical with the content of its copy or another version. This can be for example a PDF original, that was later printed, scanned and archived.

One such a scenario can be found in the legal sector:

  • A contract can be created by Company A and sent as PDF to Company B.
  • The relevant person at Company B prints and signs the contract. Then, the contract is sent back to Company A for a signature - per mail as a letter or scanned as an e-mail attachement.

How can Company A be assured that the original content was not amended in any way?

Instead of tedious re-reading of every word, the ABBYY technology for document comparison can be used. This functionality is for example available in the desktop application ABBYY FineReader.

With the Release 4 of ABBYY FineReader Engine 12, this document comparison technology is available for integration into own software solutions.

The new Compare Documents module enables to compare two version of the same document, regardless of their format and easily detect content differences. It is for example possible to compare document created in Microsoft Word with its PDF or TIF versions, two Word versions of the same document or for example documents photographed by Smartphones with the original PDF.

In order not to miss the most important deviations - deviations in the content - the technology will only compare content information and not report any differences in document formatting (which can be a vast amount, especially when using a document format, which might be visually slightly changed due to handling, for example due to photographing with a smartphone or sending it via a fax machine.)

The detected deviations can be provided as a Microsoft Word document with marked changes and are as well available via the API.

How quickly would you spot the difference?

Imagine, this is a 25 pages long contract…


ABBYY technology for document content comparison will detect the amendments within seconds - in any documents, regardless of its format.
