Abstract

A device (100) for authenticating a user (130) is provided, the device being configured to receive characters typed by the user using a keyboard (112) operable as input device for the device, and, for each typed character, acquire an image from a camera (120) configured for imaging the keyboard, determine which finger of a hand is used for typing the character, and derive a respective transformed character from the received typed character based on the finger (151-153) used for typing the character. The finger used for typing the character is determined by image processing. The camera may optionally be configured for imaging a reflection (163) of the keyboard by a cornea (162) of the user. By taking into account which fingers are used for typing characters related to authentication or access control on a keyboard, such as passwords, an increased level of security for is achieved.

Description

technical field [0001] The invention relates to a device for authenticating a user, a method for authenticating a user of a device, a corresponding computer program and a corresponding computer program product. Background technique [0002] Passwords are an important part of access control and authenticating users against services. Effective passwords are often described as "strong," which means they are difficult for computers to replicate. Passwords based on things that people experience in their lives (eg, names, places, dates, etc.) are generally not strong because they can be easily predicted. A password is more likely to be strong if it contains random characters, non-alphanumeric characters, or a sequence of words (often called a passphrase). [0003] However, it is often difficult to remember strong passwords, and multiple services requiring passwords means remembering a different password for each service, which is inconvenient for many people. The importance of ...
