Types of typing patterns

Typing patterns are at the core of TypingDNA’s capabilities to be able to capture a person typing behavior when they type on their keyboards. The way you capture a person biometric traits determines the quality and the accuracy of the identity recognition technology. This is why its important for developers to understand and have the right integration of typing biometrics capabilities in their platform.

Types of typing patterns and how to use them?

There are two types of typing patterns that the TypingDNA JavaScript recorder class can capture and they are used for different scenarios.

1. Sametext pattern (type: 1)

Use this type of typing pattern when you want to authenticate a user on the exactly the same text that was used when he was enrolled. Typical same texts are typed emails, usernames, passwords, first names, last names, phone numbers, credit card numbers, and short identical sentences. If you change a character of any of these, you will not be able to correctly use them.

A few good examples:

Enrollment text Authentication text
richard@email.com

Characters: 17

Function example:

tdna.getTypingPattern ({
   type: 1,
   text: "richard@email.com"
})
richard@email.com

Characters: 17
Same text as in enrollment
It's a wonderful day to explore the city on a bicycle.

Characters: 54

Function example:

tdna.getTypingPattern ({
   type: 1,
   text: "It'sawonderfuldaytoexplorethecityonabicycle."
})
It's a wonderful day to explore the city on a bicycle.

Characters: 54
Same text as in enrollment
1229169949191439

Characters: 16

Function example:

tdna.getTypingPattern ({
   type: 1,
   text: "1229169949191439"
})
1229169949191439

Characters: 16
Same text as in enrollment

A few bad examples:

Enrollment text Verification text
richard@email.com

Characters: 16
1229169949191439

Characters: 16
Same text as in enrollment

2. Anytext pattern (type: 0)

Use this type of typing pattern when you want to authenticate a user on different text then the one used for enrollment. Typical any text are typed text that is usually different each time like composing emails, writing documents, and having conversations.

A good example:

Enrollment text Verification text
Cars are useful but they pollute our environment. It's a wonderful day to explore the city on a bicycle. Which one would you choose from these two tentative options?

Characters: 165

Function example:

tdna.getTypingPattern ({
   type: 0,
   length=165
})
