Method for authorising users to perform a search

摘要

A method of authorising users to perform a search using a computer system. The method includes providing a user with a search request form having coded data indicative of an authorisation parameter. The computer system receives indicating data from a sensing device which is indicative of the authorisation parameter, movement of the sensing device and an identifier. The computer system determines the authorisation parameter and movement of the sensing device using the indicating data, and then authorises the user using the determined movement, the authorisation parameter and the identifier, before performing a search in response to a successful authorisation.
