Method for improved password entry |
摘要 |
A method of authentication is described that uses both relative and absolute values of inter-keystroke intervals measured during entry of a unique identifier. Both the relative and absolute values have to be achieved during entry of the unique identifier. The relative values are the ratio of each of the inter-keystroke intervals divided by one of the inter-keystroke intervals or divided by the average inter-keystroke interval.
