A method and apparatus for securing communications in a communications network between a first network component (e.g. user's device) and a second network component (e.g. service apparatus). At the first network component a first data set represents user-perceptible content which is reproduced for perception and selection by a user of the first network component. The method includes forming a network communications link between the first network component and the second network component subject to conditions requiring at least that a user input (47) is received at the first network component indicating selection of the reproduced user-perceptible content by the user. The first data set is then replaced at the first network component with a second data set to represent the user-perceptible content for perception and selection by a user of the first network component in subsequently so forming the communications link. Both first and second data sets are derived from and differ from a master data set.
