Vocal Biometry What Does It Consist Of

Voice biometrics is a technology that works as a consumer authentication system. The use of voice is essential today. The main drivers of this type of technology are smartphones and mobiles, which allow you to carry out many daily tasks, such as unlocking devices, transfers and payments, etc.

Voice biometrics captures each user’s unique features, their speech apparatus, to identify them with certainty. This technology analyzes more than 100 physical parameters of the voice, the vocal frequency, and the oral-nasal cavity in such a way that the index of certainty is absolute. Practically similar to a fingerprint but through voice.

Advantages Of Voice Biometrics

Voice biometrics has multiple advantages, among others that:

• The voice is unique to each human being. This technology detects and evaluates the voice taking into account the physical characteristics and speech behavior.
• It is a type of technology outside the security threats presented by the pins and number combinations. Faced with aphonia or lack of voice, he presents other compatible alternatives such as certain questions for access to certain information.
• What can we do with voice biometrics?

Voice biometrics is becoming so important that more and more companies carry out biometric projects of this type.

1. Device Unlock

Although fingerprint or facial recognition are authentication technologies working in the market, they need more sophisticated cameras and sensors, unlike voice biometrics, which requires only a micro to unlock a mobile. 

2. Transactions And Payments

Second, voice biometrics is quite secure to allow online transactions and payments, saving you from remembering passwords to make purchases, for example.

3. Open And Start A Vehicle

Although it is not yet underway, it is expected that cars can be opened and started through voice biometry in the short term. A voice recognition system that allows identifying the driver for certain car settings.

4. Voice Biometrics, A Real Discovery For The Tourism Sector

The tourism sector is one area in which voice biometrics can have the most impact and benefits. From hiring a trip with voice assistants (booking a flight) to customer identification tools in hotels (for example, checking-in to opening hotel room doors).

Unquestionably, it is a useful system that offers us great advantages by facilitating our day today. However, like any device connected to the Internet, there are some risks that we must take into account. One of them is ‘voice hacking ‘.

However, first, it is important to know that there are two ways in which voice assistants can be compromised: from the Internet connection itself and from within the physical space in which they are used.

• Secure It Using The Singing Method or Singing Password: To do this, use the first letter of each word of your favorite song. You should not use password words that may appear in a dictionary of any language in the world, and you should try to make it usually have more than 15 characters. Also, the password of the Wi-Fi router must have at least WPA2 security. 
• Keep Your Voice Assistant Away From SmartTVs, Audio Equipment or Radios & Windows That Face The Outside: For this, you will have to “deafen” your voice assistant by placing a stuffed toy, or any material that absorbs sound waves, or even an adhesive tape fine, in front of the microphone hole (usually labeled MIC) to reduce the microphone’s pickup sensitivity and thus prevent the assistant from executing commands from afar. This may sound crazy, but there have already been reports of “automatic shopping” when voice assistants hear malicious words or advertisements (with phrases like “Alexa, buy a yacht” or “OK Google, open the front door”).
• Do Not Say Any Voice Commands In Front Of Strangers: You can configure the assistant so that it does not give answers aloud. The goal is to prevent a stranger from recording your voice and then imitating it with sound editing software. Which would allow you to give commands such as “Alexa, open the back door” or “OK   Google, check my bank statement.”
• Ask Someone You Trust To Try To Execute Commands On Your Behalf To Verify That It Only Responds To The Sound Of Your Voice: To make this happen, configure the ‘ voice match ‘ option (a function that recognizes your own voice in the Google Home virtual assistant) or the Alexa 4-digit ‘ voice code ‘ on the Amazon Echo (4-digit secret code before making a purchase). This will allow the assistant to “teach” to recognize only your voice (vocal biometry) and also program it so that it only shows results when it listens to you. This will prevent someone else from accessing your data.

The post Tips To Avoid The Voice Hacking appeared first on Web Updates Daily.

The lockdown has caused companies to assume or accelerate their digital transformation so that they could continue operating while protecting the health of workers. This transition to the virtual environment has revealed challenges that still need to be resolved for this migration to be successful.

Beyond the security that the blurring of the physical borders of companies implies, there are issues such as the agility that CIOs require when looking for technologies that allow the benefits of digitization to be transferred to organizations. Biometric Vox highlights voice technology as one of those that most facilitates this transformation.

In this sense, CIOs are recommended to explore new technologies such as voice biometrics that, due to their versatility, ease of use, reducing contact with contact surfaces, agility, and affordability, can help them respond to the challenges in their digital transformation. But what deficiencies have the health crisis revealed and how can vocal biometry solve them?

• Security: Facilitating staff access to information and corporate systems without compromising the security of the organization is today, one of the main concerns of CIOs. In this sense, the use of voice as an access interface ‘shields ‘business resources to the extent that the biometric parameters of the human voice are unique to each person. This means that they uniquely identify the user and cannot be imitated or stolen, drastically reducing the chances of identity theft. Voice biometrics accurately distinguish a recording and a live voice, preventing deliberate attacks.
• Agility: The COVID-19 pandemic has changed the work environment overnight, leading some companies to ‘improvise’ secure access outside of the corporate network that has proven to be inefficient. Voice biometrics allows, without the need for large investments, to create secure access to the business network. The only requirement is the existence of a microphone, already present in all current devices, tablets and computers, and biometric software that takes a sample of the employee’s voice to create a unique voiceprint.
• Easy To Use: The new reality of mixed work encourages the adoption and implementation of technologies that can be used simply, to reduce as much as possible the need to carry out training and learning processes for new computer programs. Speech biometrics only requires the user to speak for the system to recognize them. This avoids having to memorize and remember passwords and even use it to identify yourself on different platforms or applications with the risks that this entails.
• 100% Digital: The confinement has transferred the daily operations of the company to the virtual environment. The implementation of digital solutions such as voice signature allows streamlining internal and external operations by carrying out remote procedures from anywhere and in a few seconds, with all the security guarantees. This is relevant, in sectors such as banking, insurance, or the tourism sector, among others.

In this new normal, and given the impossibility of predicting all the risks that have become clear with the sudden outbreak of COVID-19, organizations must be prepared for environments with high uncertainty and volatility. For this reason, they must equip themselves with technologies that provide them with the flexibility and agility necessary to adapt immediately to the new reality and the changes that will continue to occur.
