## Abstract

A method and apparatus for receiving an image associated with an interactive service on at least one social media server, the image belonging to a group of images. The image is stored and accessing of the image by a user is detected. In response, a request with an identification of the image is sent to a back-end server to access the interactive service. Interaction messages are exchanged with the interactive service so that the interactive service associated with the image is made available to users by accessing the image.

## Background
TECHNICAL FIELD
The aspects of the disclosed embodiments generally relate to image based interaction.
BACKGROUND ART
THINGLINKTM has developed a system that lets users add interactive links to any photo and turn them into fun web experiences that drive engagement.
THINGLINK'sTM Rich Media Tags feature popular media players and applications from YOUTUBETM, VIMEOTM, SOUNDCLOUDTM, GOOGLE MAPSTM, SPOTIFYTM, FLICKRTM, FACEBOOKTM, TWITTERTM, LINKEDINTM, AMAZONTM, eBAYTM, BESTBUYTM, iTUNESTM, ETSYTM, MAILCHIMPTM and FANBRIDGETM.
In practice, one image with interactive spots can be linked from its origin to a number of different internet publications. On moving a mouse pointer onto a marker of one of such spots, an associated script causes that a small preview of explanation of linked content appears. On clicking with a mouse on the marker, the script causes that a corresponding action takes place.
While the THINGLINK'sTM system provides great advance in its image interaction, further improvements and alternatives for image based interaction are still desired.

DETAILED DESCRIPTION
FIG. 1 shows a flow chart of a method according to an example embodiment illustrating operations at a back-end server. The method comprises following main steps:
110 Storing a group of images, e.g. when a user uploads the image to the back-end server. The group may comprise one or more images e.g. of similar subjects. For instance, the images of the group can represent a new album of a rock star, the rock star and/or various associated items such as music videos and books.
120 Associating the group of images image with an interactive service on at least one social media server. This can be done, for instance, by the user defining actions to be associated with the image.
130 Making the group of images available to a plurality of image publishers. For instance, the image can be distributed in a variety of different blogs, emails, advertisements of electric distributions, Facebook posts or even printed publications such as magazines or posters.
140 Receiving from a requesting apparatus a request to access the interactive service associated with the group of images. The requesting apparatus is a term that can refer to, for instance, a content server or a user terminal with which a user photographs a printed image of the group of images and interacts with the back-end server. In some embodiments, the request comprises an identification of the location of a given image of the group of images on the content server. The location information enables determining the sources of requests to the interactive service based on the given image and thus enables providing of valuable further services.
150 Exchanging interaction messages between the requesting apparatus and the interactive service so that the interactive service associated with the group of images is made available to users of any of the plurality of image publishers by accessing any image of the group of images.
In practice, the operation of the content server or user terminal can be conveniently controlled by providing a suitable script with one or more actions associated with the group of images. The script can be obtained, for instance, from the back-end server by using the identifier of the image to identify a script with desired actions associated with the group of images.
The interactive service can be associated with a given spot on an image, i.e. hotspot. The interaction service can then be accessed by a user by accessing the given spot on the image. The hotspots can be individually located on different images of the group of images. Alternatively, the hotspots can be aligned e.g. by an image object recognition software configured to detect potentially distinguishing parts in the images. Further alternatively, the hotspots can be aligned according to a predetermined matrix or other grouping.
The images of the group of images can be associated with an image identifier. The given spot can also or alternatively be associated with an image spot identifier. In some embodiments, the image spot identifier and the image identifier may collectively define the image and the given spot of the image. Alternatively, the image spot identifier can be capable of uniquely identifying the image and the given spot on the image. The image identifier and/or the image spot identifier can further alternatively uniquely identify the group of images.
The image identifier and image spot identifier, when present, are stored by the back-end server that further distributes the identifiers to entities in need of them. In one example embodiment, the identifiers are delivered as attached to the images. This can be simply done by using metadata of image files and/or by using watermarking in which technique information is coded into the images themselves such that the difference is not perceivable by a human being but can be decoded by a computer.
At least one of the interaction messages may comprise the image identifier. Alternatively, or additionally, at least one of the interaction messages may comprise the image spot identifier.
In an example embodiment, the interactive service comprises a commenting functionality configured to enable users to post comments.
The interactive service comprises in one example embodiment a ranking functionality. The ranking functionality in one embodiment enables a user to vote e.g. by liking or disliking content in the interactive service.
FIG. 2 shows a flow diagram of a method according to another example embodiment at a content server or user terminal. The method comprises following main steps:
210 Receiving an image associated with an interactive service on at least one social media server, the image belonging to a group of images. In case of a content server, the image can be received from an uploading user, for instance. In case of the user terminal, the image can be e.g. a printed image that the user can photograph. Once optically read into the user terminal, the user terminal can perform, according to an example embodiment, a feature analysis that results in fingerprints of the image based on which the image can be recognized. In another embodiment, the printed image is supplemented with a machine readable code such as a bar code or near field communications code that provides the user terminal with the image identifier or its derivative.
220 Storing the image.
230 Detecting accessing of the image by a user (e.g. idle or perform other tasks until the user has accessed the image) and responsively:
240 Sending to a back-end server a request to access the interactive service, the request comprising an identification of the image. This request can be triggered by user action such as clicking a hotspot on the image by a user of a content server or by the user taking an image of a printed image or issuing a command through a user interface of the user terminal. The request comprises, in an example embodiment, an identification of the location of the image on a content server.
250 Exchanging interaction messages with the interactive service so that the interactive service associated with the image is made available to users by accessing the image.
An example embodiment further comprises receiving from a back-end server a script and storing the script. Access to the image can be detected by the script.
The script can be used also or alternatively for sending to a back-end server an identification of the location of the accessed image on the content server and a request to access the interactive service. Further additionally or alternatively, the script can be used to cause the exchanging interaction messages with the interactive service.
The image fingerprint mentioned above can be specific for the entire accessed image or to the respective group of images. Alternatively, different objects in the image can be represented by individual fingerprints so as to discover use of a cropped part of an image such as a person appearing in the image.
In an example embodiment, the identification of the image is formed based on the one or more fingerprints. The forming of the identification of the image can be made e.g. by querying for the identification with a query request comprising the one or more fingerprints. Alternatively, the identification of the image can be formed from the one or more fingerprints. The fingerprints can be, for instance, combined using a concatenation operation.
