Today, the need to verify the identity of users remotely is becoming more and more important. Companies that offer digital services, such as contracting financial products or opening accounts online, must ensure that the people who access their services are who they say they are.

The importance of identity verification

Identity verification is a fundamental aspect of ensuring the security of online transactions and preventing fraud. However, it has traditionally been a slow and expensive process, requiring users to physically interact with an agent to verify their identity.

Fortunately, thanks to technological advances, it is now possible to verify a person’s identity remotely and securely. This allows companies to save time and money, while providing a faster and more convenient experience for users.

How can an identity document be verified?

There are different methods that can be used to verify an identity document remotely. Here are some of the most common:

Method 1: OCR (Optical Character Recognition)

OCR is a technology that allows you to convert an image into text. In the context of identity verification, it is used to extract relevant information from an identity document, such as name, identification number, and date of birth.

To verify a document using OCR, a sharp, high-quality image of the document must be captured and then processed using specialized software. The software will use advanced algorithms to recognize the characters and extract the necessary information.

Once the information is extracted, different techniques can be applied to validate the data, such as consistency checking between fields, comparison with external databases or other user identity documents.

Method 2: Facial biometry

Facial biometrics is another technique used to verify a person’s identity remotely. It consists of comparing the image of a person’s face captured in real time with the image registered in the identity document.

To carry out this verification, it is necessary to use sophisticated facial recognition algorithms that can detect and compare specific features of the face, such as the shape of the eyes, nose and mouth.

Facial biometrics are often used in combination with OCR to more accurately verify a person’s identity. This combination allows the data extracted from the document and the facial image of the person to be compared in real time, which increases security and reduces the risk of fraud.

Method 3: Documentary validation

Document validation consists of verifying the authenticity of an identity document through different techniques, such as the detection of holograms, watermarks, invisible inks and other security elements.

To carry out this verification, specialized devices are used that can examine the document and detect any signs of forgery or manipulation. External databases can also be used to check if the identification number corresponds to a real person.

Document validation is especially important in regulated industries, such as the financial sector, where it is essential to ensure compliance with KYC (Know Your Customer) and AML (Anti-Money Laundering) regulations.


Remote identity verification is critical in today’s digital world. Fortunately, there are different methods that can be used to verify an identity document, such as OCR, facial biometrics, and document validation. These methods allow companies to guarantee the authenticity of the user’s identity quickly, securely and conveniently.
