ON-LINE BROWSING PREFERENCE MANAGEMENT

A computer-implemented method of providing one or more selected tracking tags to a domain owner server for deployment on a website is described. The one or more tracking tags are selected from a set of available tracking tags and the method comprises: storing the set of available tracking tags, each available tracking tag including a purpose parameter describing a use to which data collected by the available tracking tag will be put; storing a plurality of user identifiers and a plurality of sets of tag-selection parameters, each user identifier identifying a website user and having an associated set of tag-selection parameters which identity a specific tracking tag and indicate whether a user consent has been obtained for a specific purpose of the specific tag; receiving, from the domain owner server, a request for deployment of one or more tracking tags on the website, the request including a received user identifier identifying a user accessing the website; for a user identifier corresponding to the received user identifier, comparing the tag-parameters for each specific tracking tag to the purpose parameter of each corresponding available tracking tag; selecting available tracking tags where the purpose parameter of the available tracking tag corresponds to a specific purpose which has an indication of user consent in the corresponding tag-selection parameters; and transmitting the selected available tracking tags to the domain owner server for deployment on the website.
