Abstract: An apparatus, method and computer program is described comprising: means for capturing a presentation (106) on a display (104a), wherein the presentation (106) includes data representative of a first hash (108); means for generating a second hash (111) from the captured presentation (122); means for reading a digital code (107) from the display (104a) or the captured presentation (122), the digital code (107) comprising the first hash (108) and a digital signature (109) associated with the first hash (108); means for comparing the first hash (108) and second hash (111); and means for sending an indication on whether the digital signature (109) is legitimate in response to the first and second hashes (108, 111) at least substantially matching.
