The Freedom of the City of Dublin is awarded by Dublin City Council after approving a person nominated by the Lord Mayor. Eighty people have been honoured under the current process introduced in 1876. Most honourees have made a contribution to the life of the city or of Ireland in general, including politicians, public servants, humanitarians, artists and entertainers; others were distinguished members of the Irish diaspora and foreign leaders, honoured visiting Dublin. Honourees sign the roll of freedmen in a ceremony at City Hall or the Mansion House and are presented with an illuminated scroll by the Lord Mayor.

This touchscreen was for the City of Dublin Exhibition at Dublin Castle. It functioned as a database of biographies for the people who have been granted the key to the city and included a game where the user had to match the signature to the portrait of the signatory.
