Abstract: A method for verifying a person's identity is of the general type which comprises storing a personal pattern of a pre-determined number of locations on a grid in association with personal identification data, and subsequently using the pattern in a verification process. According to the invention, the subsequent verification process comprises the steps of: (a) presenting to the person a challenge grid of locations occupied by a pseudo-random set of symbols, and challenging the person to identify a response set of symbols occupying locations in the challenge grid corresponding to the stored personal pattern; (b) receiving from the person the response set; (c) generating from the challenge grid and the stored pattern a verification set of symbols occupying locations in the challenge grid corresponding to the stored personal pattern; (d) comparing the response set of symbols with the verification set of symbols; and (e) verifying the identity of the person if the response set is the same as the verification set.

Abstract: A glazing panel having a decorative pattern comprises a laminar insert of plastics material deformed to replicate a desired decorative pattern positioned between two opposed sheets of glass or other transparent glazing material. The deformed laminar insert has areas which lie in contact with one of the glazing sheets and areas spaced from that sheet and the other glazing sheet of the panel. The areas of the laminar insert in contact with the glazing sheet are bonded to the glazing sheet using a resin which retains a degree of flexibility when set. The spaces defined between the laminar insert and the glazing sheet are entirely filled with a hardenable resin material.
