DUAL INPUT CONTENT PROCESSING METHOD AND DEVICE

A content code is defined containing user content, and a corresponding profile code defining user context information. The profile code may be scanned and stored temporarily in a user device or elsewhere. The user content can then be modified on the basis of the stored context information. In some cases the context code and profile code may be separate, so that a given profile code may be applied to diverse pieces of content, or may be combined. The stored context information may be undated or modified when particular events, such as re-scanning a code, occur. The codes may comprise binary codes, such that the profile code and the content code can be compared by a logical operation. Embodiments include a mechanism for presenting different notice information to different users on the basis of their profile codes, implementing a game such that the number of attempts are counted by refreshing the stored version of the profile code, and identifying cases where a list of ingredients stored in the context codes matches an ingredient corresponding to an allergy, intolerance or the like as specified in the profile code.
