Abstract
An association is created in a computer system between the appearance of a token and one or more stored files for the purpose of retrieving and presenting said one or more stored files. The appearance of the token is measured and a token identity is created from the obtained measurement. The token identity is stored in an identity store. The stored file is associated with the token identity within the computer system. The appearance of the token is subsequently measured and a subsequent identity is created for the token using subsequent measurement data obtained from the subsequent measurement. The identity store is searched for a match with the subsequent identity and upon the location of a match, the one or more stored files are retrieved and presented to a user.
