Lleidanetworks Serveis Telemtics SA: Trends in biometric identification


With the development and use of new technologies, various methods of fraud have also become widespread in identifying individuals regarding their interaction with other businesses or individuals. Security is fundamental for businesses such as banks and telecommunications companies and customers, and biometric facial identification, among other trends, has become one of the main methods. This article explains what biometric identification is, trends in biometric recognition and the most common applications of this technology.

In this regard, a survey conducted by IBM showed that biometrics and multi-factor authentication are the two preferred securities options and found that 75% of participants use biometric identification and authentication tools, compared to 1 in 3 who use complex passwords.

What is biometric identification?

Biometric identification identifies an individual through physical characteristics or behavior so that the identification is unequivocal. Some of the most common technologies in biometrics include facial biometric identification, hand geometry, voice or iris recognition, or signature traces.

On the other hand, facial this identification consists precisely in using one or more features of a person’s face to identify him. Facial biometry measures the iris and analyzes the shape of the eyes, the distance between the eyebrows or from the nose to the eyes, for example.

What trends can we highlight in biometric identification?

Biometric identification uses increasingly advanced techniques to prevent fraud or identity theft of individuals, for example by preventing a person from using another person’s image to open a bank account. Here are the most relevant trends in facial ID and other types:

  • Combine several biometric techniques. As we have already mentioned, security is fundamental in online transactions; thus, two or more biometric data are often used to identify a person. For example, facial features such as the iris and other features such as voice or DNA are used together. The level of security may vary, for example a fingerprint or a face may be sufficient to unlock a cell phone, but for the identification of people by police patrolling the streets a higher level of security will be required.
  • Liveness detection. An example of identity theft is a static image taken from a social network profile. This is done by using the person’s photo so that it can be compared to a reliable source image. Brightness detection can be used to prevent fraud. Currently, there are several forms of alertness detection, such as prompting the user to move their head so that they can be verified as a real person, 3D facial biometric ID, or thermal image.
  • Recognition of emotions. Emotion identification can be used in vehicles to increase safety, as it lets us know if the driver is tired, or in video games to see how players feel when they score points in a particular game. . Using this technique, facial movements are digitally captured and then compared to various facial patterns that have been categorized according to different emotions.

Applications using biometric facial identification

Facial biometric identification applications are growing, and currently the following can be highlighted:

  • Security forces use it to fight crime or to identify people at national borders.

  • Safety in public places (parks, public buildings, etc.).

  • Identification of travelers.

  • Detection of genetic diseases in patients.

  • Detection of the patient’s condition.

  • Photo KYC (Know Your Customer) or KYB (Know Your Business).
  • Analysis of customer emotions in retail.

  • Sign contracts with electronic signature

  • Sign documents with electronic signatures.

  • Access to offices, buildings and other facilities

  • Unlocking cell phones and tablets.

  • Contracting of public services (telecommunications, electricity, etc.).

  • Customer onboarding process.

  • Transactions with public administrations: registration or deregistration, tax payments, grant applications, etc.

In short, Biometric facial identification is an evolving technology due to its many applications and the level of security it offers. Therefore, regulatory developments must always accompany future developments to ensure that biometric identification complies with regulations on the protection of personal data and guarantees the right of individuals to privacy.
