Before the internet, document verification was a lengthy and laborious task. It often required document-by-document review and manual recording of data. With the emergence of online document verification, companies have the ability to quickly and accurately complete document verification processes.

Online document verification is required for many different reasons. Such as, verifying customer identity, document authenticity, and checking for document compliance.

There are various techniques for document verification that can be used to quickly and accurately verify documents. Let’s look at some of the most common document verification techniques that businesses can use.

1. Optical Character Recognition (OCR)

OCR is a method of document recognition and document processing. It uses optical character recognition to recognize text on scanned documents, enabling document data to be extracted quickly and accurately. This document verification technique is popular for document verification, as it eliminates the need for manual document review and data entry.

However, this document verification technique has certain limitations too. If a document contains handwritten or stylized fonts, OCR may not be effective.

2. Artificial Intelligence (AI)

An AI-based document verification process uses machine learning algorithms to identify document features and data. The AI scans the document uploaded by the user and looks for specific document features, such as signatures, seals, and texts, using computer vision and OCR. However, it also validates document data by cross-checking it with verified document databases.

These document verification tools are capable of scanning a document in its entirety. They extract text, images, and document data accurately. AI document verification tools can also detect document errors and fraud, making them effective document verification tools for businesses.

3. Facial Recognition

Facial recognition document verification uses biometric technology to verify document authenticity. This document verification technique scans a user’s face and matches it with their uploaded document, such as a passport or driver’s license.

It is an effective document verification technique for verifying the identity of document holders. Facial recognition document verification is incredibly fast and accurate. This makes it ideal for businesses that need to verify document authenticity quickly.

There are two types of facial recognition verification: 2D and 3D. 2D facial recognition document verification requires users to take a selfie, while 3D document verification uses sophisticated computer vision and depth algorithms. The latter is the more accurate, secure, and widely used method of the two.

4. Digital Signature

Digital signature document verification uses digital signatures to verify document authenticity. This document verification technique requires users to sign a document using their device electronically. This document is then matched with an existing document to verify document authenticity. Digital signature document verification is becoming increasingly popular. It is a secure, fast, and cost-effective document verification technique.

5. Fingerprint Matching

Like facial recognition document verification, fingerprint verification uses biometric technology to verify document authenticity. It scans a user’s fingerprints and matches them with their uploaded document, such as ID cards.

Fingerprint document verification is incredibly accurate and secure. It is often used for document authentication in government sectors. Such as for voter authentication or Aadhar card verification.

In some cases, facial recognition and fingerprint document verification can be combined for enhanced document authentication and document verification accuracy.

6. Barcodes/QR Codes

Barcodes and QR code verification is a document verification technique that uses optical scanning technology to decode information encoded in barcodes or QR codes. The document verification tool scans the document for a barcode or QR code and decodes the encoded information. This document verification technique is used to verify document information that humans. Such as document expiration dates or serial numbers, cannot easily read.

This method has certain limitations too. For instance, this method requires a document to have a valid barcode or QR code. Additionally, if the document has been tampered with, this document verification technique may fail. An internet connection is required for document verification using this document verification technique.

7. Blockchain

Blockchain document verification is an emerging document verification technique that uses blockchain technology to store document data securely. It stores document hashes on a distributed ledger, creating an immutable record of document authenticity. This document verification technique is ideal for verifying document authenticity, as it makes document data tamper-proof and secure.

Conclusion

These are the seven most common document verification techniques used today. All of these document verification methods have their own strengths and weaknesses. So it is important to consider the document type, volume, and accuracy requirements when deciding which document verification technique is best for the business. With the right document verification techniques, businesses can ensure document accuracy and compliance while making document verification more efficient.
