The demand for online services and products is increasing at an unprecedented rate. With this shift to adopting online platforms, it becomes vital for businesses to confirm the identity of their customers via an online portal.

Online Document Verification is imperative for businesses to ensure safety, eliminate misuse of services and render better customer experiences.

For example, ride-sharing apps need online document verification to ensure both the rider and driver are identified as real individuals. Online document verification is important to fight online identity theft and make online experiences safer.

Let’s dive into the guide to document verification and learn more about it with illustrative examples.

What is document verification?

In a traditional setting, the original ID card or passport was the way to verify the true identity of an individual. But in an online setting, online document verification is crucial to building trust amongst the target audience.

Document verification is the process of verifying the authenticity of a document.

Document verification is used to check the originality of submitted documents, extract information using OCR software like Nanonets, and confirm genuine microprint text and facial recognition for matching identities.

There are many official documents that can be verified by using a document verification software like Nanonets:

  • ID card
  • Passport
  • Driver’s License
  • Bank Statement
  • Utility Bill
  • Tax bill
  • Insurance Agreement
  • Employment documents
  • Educational Documents
  • Employee Letters & many more

The document verification process checks document features, such as stamps, watermarks, holograms, fonts,  or other security features, and automatically approves the document. This automation saves time and effort for the organization and frees up employees’ time to provide better services.

How to automate the document verification process?

Check that the security features are in the right place

Every ID document comes with its own unique set of security features, such as watermarks, logos, holograms, and microprint. Checking that these security features are where they are supposed to be is a solid first step in verifying the document is real. All that is needed is a clear image of the document to be able to verify its security features.

The end result should be a clear, horizontally aligned image of the document.

Compare the ID data for consistency

Every ID has the document holder’s personal data encoded in some way - whether in a barcode or a Machine Readable Zone (MRZ). Any mismatch between this data and the data printed on the rest of the document ( its so-called  Visual Inspection Zone, or VIZ) is an indication of tampering.

Match the user’s face with the portrait on the document

One more way of verifying a document is to compare the ID photo and uploaded selfie of the customer. In the event the characteristics on these two images match, the user is the genuine owner of the submitted document.

Document process automation is the design of systems and workflows that assist in the creation of electronic documents. These include logic-based systems that use segments of pre-existing text and/or data to assemble a new document. This process is increasingly used within certain industries to assemble legal documents, contracts, and letters. Automation systems allow companies to minimize data entry, reduce the time spent proof-reading, and reduce the risks associated with human error.

Reduce fraud, improve customer turnaround time and ensure compliance with smart document verification workflows.

What is the Document Verification Process?

The document verification process is simple, data is collected at the source from the customers, and then it undergoes data extraction where selective data is extracted from the required documents. The documents are validated and checked for authenticity by various AI checks which reduces identity thefts. And after going through human in the loop process, the document is finally verified. Let's take a look at all the steps in detail below:

Step 1 : Document Collection & Data Capture

In the first step, the required documents are submitted. The customers are asked to upload the photos or videos of the relevant ID documents in high quality. The AI and algorithms scan the document for information, including the encrypted data, and recognize it.

In the first step, the documents are pre-processed and are made ready for the next step. This includes checking the borders of the documents, de-skewing the images, and improving the color and brightness of the image to ensure better data extraction at the next step.

Step 2: Data Extraction

In the second step, the required information is selectively extracted from the documents. With intelligent document processing software like Nanonets, users can select the information that is important and discard all the other irrelevant information.

Document Data Extraction : Nanonets vs others

As opposed to a simple OCR software, it is better to use Nanonets as it converts your entire document into a structured informational document that can be directly fed into your next data sources as required. At this step, you can also classify the document based on their templates and ensure proper documentation of all the customer documents without fail.

Step 3: Document Validation

Validation of the data extracted from the scans requires establishing if the document and the info shown are still valid. Based on the extracted data, you can match the extracted information against any data source to check its validity. For example, the loan processing department might want to check if the person applying for a loan has any present loans in the same bank. Document validation is imperative to reduce identity thefts and frauds.

Some of the validation checks that automated identity document verification solution conducts:

  • Face and orientation detection
  • Edge detection and cropping
  • Front to back correlation
  • Cross checks on thousands of global IDs
  • Colourspace analysis
  • Headshot integrity
  • Selfie to ID photo match

Step 4: Document Verification

As a final step, the documents which are flagged due to any error are sent through an approval process. This symphony of manual and automated workflow is often called the human-in-loop verification process. After checking for everything, the documents are then verified.

Onboard customers, employees, or patients in minutes with automated document verification workflows.  Just upload the documents and let Nanonets do the rest.

What is the role of the Document Verification Executive?

The Document verification executive steps in the fourth step of the document verification process. These are the tasks that they carry out on a daily basis:

  • Collecting documents from the selected candidates
  • Maintenance of employee files and other documents
  • Responsible for employee verification
  • Understanding the requirement on manpower from the business and sourcing candidates
  • Conduct background verification for all new hiring (need to be done before joining)
  • Responsible to maintain recruitment and employee master data

What are the benefits of using online document verification?

Businesses reaping a fair share of success due to their growth and appeal of ideas need to tackle the complex web of fraudsters who’re ever-present at their cyber portals.
