METHOD FOR AUTHORISING USERS TO PERFORM A SEARCH

A method of authorizing 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 authorization parameter. The computer system receives indicating data from a sensing device which is indicative of the authorization parameter, movement of the sensing device and an identifier. The computer system determines the authorization parameter and movement of the sensing device using the indicating data, and then authorizes the user using the determined movement, the authorization parameter and the identifier, before performing a search in response to a successful authorization.
