摘要:
Methods are described for securing access to an electronic annotation provided on an object. The methods include the steps of providing the object with a plurality of memory tags, providing an electronic annotation on at least one of the memory tags, and defining a sequence in which the memory tags must be accessed in order to access the annotation. A corresponding object is also described.

A cellular communications service provider authenticates a provider of a location-dependent service, such as a wireless hotspot. Once the cellular communications service provider is aware of potential use of the service by the user, it authenticates the service provider and provides an authentication to the user. Users can thus avoid untrustworthy providers of local services.

A standalone memory device is provided that when in a first state allows data to be written to the device from a data source but prevents a normal user from useably accessing that data. When in a second state the device enables the user to useably access data stored in the device. The device is arranged to implement a prohibition or restriction on re-entry to its first state after having left it. In preferred embodiments, the device limits the number of times or the frequency at which, it re-enters its first state, whereby to limit the amount or rate of transfer of data via the memory device from the data source to a data recipient. The device can be used to limit content download from data sources at an exhibition. A system and method using the device are also provided.
摘要:
A memory tag has a memory. Associated with the memory tag there is a readable structure. The readable structure can be read to generate an identifier. However, the readable structure cannot be provided so as to encode a predetermined identifier.

The presence of persons is detected, for example, by detecting short-range communication devices carried by the detected persons. The interests of the detected persons are then determined by reference to specific interests transmitted by the user devices and/or by reference to customer profile data. The discovered interests of the current detected persons are then used to select content for display on an electronic display during a next display slot. The display is spaced from the zone in which the persons are detected, being located at a downstream location through which most of the detected persons will pass.

The proximity of potential customers to a shop is detected, for example, by detecting short-range communication devices carried by passers-by. The interests of the detected passers-by are then determined by reference to specific interests transmitted by the passer-by devices and/or by reference to customer profile data. The discovered interests of the current passers-by are then used to select content for display on a shop-window electronic display during a next display slot. Passers-by who may be particularly interested in the displayed content are preferably sent an alert. In other embodiments, the targeted audience is a static group, such as train passengers, with the targeted information being displayed at a station.
摘要:
A user is pre-qualified for a service provided at a particular location. Location data indicative of where the service is to be triggered and a service element are stored. The service instance element is a full customised instance of the service delivery code or other item that provides an association between the user and an instance of the service for which the user is qualified. The user location, as indicated by a mobile entity associated with the user, is periodically checked against the location data. When a location match occurs, the service instance for which the user has been qualified is executed to deliver the required service to the user. An example is an airline traveler buying, from a travel agent, an air ticket having an associated service wherein, the traveler, upon arriving at the relevant airport, is contacted via its mobile device and guided through check-in and boarding.
摘要:
A method of storing, accessing and displaying electronic data features: storing a first part of the data in a memory tag; storing a second part of the data in a separate location having an address, using a reader, when data is accessed, to couple to the memory tag and access the first part of the data and, while or after the first part of the data is being displayed on a screen, and using a communication unit to link to the address of the separate location and obtain the second part of the data.
摘要:
A print has a substrate and a plurality of memory tags coupled to the substrate. The print is an index print including a plurality of images and a memory tag is associated with each image for storage of data relating to that image. A print medium suitable for forming such a print has a substrate with a printable surface and a plurality of memory tags coupled thereto at locations spaced apart over the area of the substrate. Alternatively, memory tags may be applied to a printed print medium. Methods of providing printed images with associated stored data are described.
