Definitions
- the embodiments herein relate to systems for management of access to services, such as content services, SaaS:s (Software-as-a-Service) or the like.
- a method and a mobile entity for enabling access to a service e.g. providing content and/or a function
- a method and a server for managing access to a service e.g. providing content and/or a function
- a method and a system for providing a service e.g. providing content and/or a function, to at least a first mobile entity and are disclosed herein.
- access to content is given based on which user attempts to access the content. For example, subscribers to a video streaming service are granted access to view the videos provided by the video streaming service.
- a particular Guick Response (OR) code, or Radio Frequency Identification (RFID) tag can be read by a reading device, such as a smartphone or the like, which depending on the data stored, such as an Uniform Resource Locator (URL), invokes e.g. a webpage.
- a reading device such as a smartphone or the like, which depending on the data stored, such as an Uniform Resource Locator (URL), invokes e.g. a webpage.
- URL Uniform Resource Locator
- the URL may be transferred to the reading device via Bluetooth technology.
- the reading device can also write new information if the tag allows this, but the tag itself is passive and has no calculation means. Hence, it has no way to alter its own data.
- Bluetooth With Bluetooth, communication over various distances, typically up to some tens of meters, can be achieved and data in both transmitter and receiver can be altered. Communication is negotiated securely and defines a master - slave relation between the devices involved. In special cases, so called Bluetooth broadcast may be used, which allows for one transmitter to send to many receivers.
- Wthin a single device access to content may be given if the correct key is provided.
- encrypted content in a memory of e.g. a tablet-computer may only be assessed when the correct key, or password, has been entered.
- functions in a computer- program e.g. installed on the tablet-computer, may only be accessed, or unlocked, when the user has entered an unlock password, which may have been bought from a company promoting, and selling, the installed computer-program.
- An object of the embodiments herein may thus be to at least enable provision of increased flexibility and other benefits, such as being able to indicate a mobile entity’s group affiliation.
- Group affiliation may herein be understood as that the mobile entity has formed a group with at least one other mobile entity for the purpose of gaining access rights with respect to a service. This means that the access rights to the service is dependent on the forming of groups, such as the number of affiliates, or entities, in the group.
- the service may provide content, e.g. provided by a content provider.
- the service may provide access to a function, e.g. performed by the mobile entity itself, optionally in cooperation with any affiliates in the same group as the mobile entity, and/or performed by a server, which then provides a result to the mobile entity.
- the object is achieved by a method, performed by a first mobile entity, for enabling access to content and/or a function, e.g. as authorized by a server.
- the first mobile entity detects a second mobile entity.
- the first mobile entity sends, to the second mobile entity, a first identity token indicating identity of the first mobile entity and a first indication relating to a first group affiliation associated with the first mobile entity.
- the first group affiliation indicates that the first mobile entity has detected at least one mobile entity and formed a first group with which the first mobile entity and said at least one mobile entity are affiliated.
- the first mobile entity receives, from the second mobile entity, a second identity token indicating identity of the second mobile entity and a second indication relating to a second group affiliation associated with the second mobile entity.
- the second group affiliation indicates that the second mobile entity has detected at least one mobile entity and formed a second group with which the second mobile entity and said at least one mobile entity are affiliated.
- the first mobile entity initiates generation, based on the first and second identity tokens and the first and second indications relating to the first and second group affiliations, respectively, of a group affiliation token.
- the group affiliation token indicates that the first mobile entity is affiliated with at least the second mobile entity due to detection thereof, and
- the first mobile entity sets the first indication to indicate the generated group affiliation token, whereby the generated group affiliation token is transmittable, by the first mobile entity, together with the first identity token upon detection thereof or detection of one or more still further mobile entities.
- said group affiliation token may be obtained by the first mobile entity after the generation thereof.
- the generated group affiliation token may be sent, by the first mobile entity, together with the first identity token upon detection thereof or detection of one or more still further mobile entities.
- the first mobile entity may indicate to further mobile entities and/or a server that the first mobile entity belongs to a group of mobile entities by means of the group affiliation token.
- the first mobile entity may, e.g. based on the generated group affiliation token, be allowed to access content and/or functions, e.g. previously not accessible, wherein the content and/or functions may reside locally in the first mobile entity and/or elsewhere.
- the first mobile entity may thus advantageously enable other devices, such as the server, to perform actions, such as granting access to content and/or a function, based on the group affiliation token.
- the object is achieved by a method, performed by a server, for managing access to content and/or a function.
- the server receives, from a first mobile entity, a group affiliation token.
- the group affiliation token indicates that the first mobile entity is affiliated with at least a second mobile entity due to detection thereof.
- the server determines the content and/or the function to be accessible based on the group affiliation token.
- the server sends, to the first mobile entity, a message enabling the first mobile entity to consume the content and/or the function determined to be accessible.
- the server receives the group affiliation token, it is made possible for the server to determine access to a service, e.g. providing the content and/or the function, based on the group affiliation token. As an example, it may be that the server only grants access to some specific content when the group affiliation token indicates that there are more than e.g. five mobile entities in the group to which the first mobile entity belongs. This means that the group affiliation token may be interpreted, or decoded, by the server in order to obtain the number of entities in the group of the first mobile entity.
- the server may advantageously grant or deny access to the service based on the group affiliation token.
- increased flexibility with respect to conditions for allowing and/or denying access to the service is obtained.
- the object is achieved by a first mobile entity, a server and computer programs and computer program carriers corresponding to the aspects above.

- a display such as a Liquid Crystal Display (LCD) or the like.
- the first and second mobile entities 111, 112 are equipped with at least one speaker each.
- the detection of nearby mobile entities may be performed in various manners.
- the detection may be performed by that the users of the first and second mobile entities 111, 112 activates Bluetooth and performs a so called pairing operation, which is well-known for Bluetooth devices. After the pairing operation has been performed, devices are allowed to discover and connect to each other without manual intervention, thereby allowing detection of each other. Furthermore, for Bluetooth various technologies, such as auto pairing, fast pairing or the like may be used.
- the first and second mobile entities 111, 112 may use Radio Frequency Identification (RFID) technology to detect each other.
- RFID Radio Frequency Identification
- the first and second mobile entities 111, 112 may thus comprise a respective RFID reading module and a respective RFID transmitting module, which responds with one or more tokens, when read by the RFID reading module of another device.
- the reading and response of token(s) is exemplified in one or more of actions A030 to A060.
- the first and second mobile entities 111, 112 may communicate directly or indirectly with the server 120.
- the first and second mobile entities 111, 112 may send their positions to the sever 120, which may respond back with a message indicating a nearby mobile entity that is deemed to be detected.
- GPS Global Positioning System
- a maximum distance for when to consider mobile entities to be nearby, or in the vicinity of each other, may be set according to use case of the embodiments herein.
- the maximum distance may be expressed in terms of a distance in meters, or in terms of radio distance coverage or the like. According to the first example, the maximum distance may typically be e.g. up to 10 meters, 50 meters, 100 meters, 500 meters or the like.
- the maximum distance may typically be e.g. up to 1, 2, 5, 10, 15 and 30 meters or the like.
- the second mobile entity 112 detects the first mobile entity 111 in the same or similar manner as the first mobile entity 111 detect the second mobile entity 112 according to action A010.
- the first mobile entity 111 sends, to the second mobile entity 112, a first identity token indicating identity of the first mobile entity 111 and a first indication relating to a first group affiliation associated with the first mobile entity 111, denoted ‘1 st tkn’ in the Figure.
- the first group affiliation indicates that the first mobile entity 111 has detected at least one mobile entity and formed a first group with which the first mobile entity 111 and said at least one mobile entity are affiliated.
- the first identity token and the first indication relating to the first group affiliation may be send over a Bluetooth-connection established during the detection.
- a broadcast identity may be used for transmission of the first identity token and the first indication.
- the first mobile entity 111 may send the first identity token and the first indication in response to that its RFID transmitting module, such as an RFID tag, is read by the second mobile entity 112.
- the first mobile entity 111 may be said to cause the sending of the first identity token and the first indication by storing the first identity token and the first indication in a memory of the RFID transmitting module.
- the second mobile entity 112 receives the first identity token and the first indication.
- the first and second examples as given in action A030 may apply.
- the second mobile entity 112 sends, to the first mobile entity 111 , a second identity token indicating identity of the second mobile entity 112 and a second indication relating to a second group affiliation associated with the second mobile entity 112, denoted ‘2 nd tkn’ in the Figure.
- the second group affiliation indicates that the second mobile entity 112 has detected at least one mobile entity and formed a second group with which the second mobile entity 112 and said at least one mobile entity are affiliated.
- the second mobile entity 112 may perform a duplicity check, wherein the duplicity check may mean that the second mobile entity 112 checks whether or not the second mobile entity 112 previously has detected the first mobile entity 111 by checking whether or not the first identity token of the first mobile entity 111 is present in a second list of detected mobile entities maintained by the second mobile entity 112. Previously may refer to never before or to within a past time period from the present detection of action A010.
- the second mobile entity 112 may thus register the identity tokens of detected mobile entities in the second list, either directly upon reception of the identity tokens or after the identity token has been successfully used to generate a group affiliation token, e.g. as in action A070 below.
- the first mobile entity 111 receives, from the second mobile entity 112, a second identity token indicating identity of the second mobile entity 112 and a second indication relating to a second group affiliation associated with the second mobile entity 112.
- the second group affiliation indicates that the second mobile entity 112 has detected at least one mobile entity and formed a second group with which the second mobile entity 112 and said at least one mobile entity are affiliated.
- the first mobile entity 111 may also perform a duplicity check, wherein the duplicity check means that the first mobile entity 111 checks whether or not the first mobile entity 111 previously has detected the second mobile entity 112 by checking whether or not the second identity token of the second mobile entity 112 is present in a first list of detected mobile entities maintained by the first mobile entity 111.
- the first mobile entity 111 thus registers the identity tokens of detected mobile entities in the first list, either directly upon reception of the identity tokens or after the identity token has been successfully used to generate a group affiliation token as in action A070 below.
- a purpose of the duplicity check may be to avoid that the first mobile entity 111 initiates generation as in action A070 below from the same identity token more than once. Should generation be initiated more than once, it may appear as if the first mobile entity 111 has detected several other entities, when the first mobile entity 111 in fact merely detects one and the same mobile entity several times.
- the detection e.g. action A010 and/or A020
- This may be applicable for a scenario using Bluetooth.
- the first and second mobile entities 111, 112 may not be possible for the first and second mobile entities 111, 112 to detect each other again, when there already is an established connection between them.
- the duplicity check may sometimes be omitted.
- the first and second mobile entities 111, 112 may also monitor, or get notified, when the established connection is disconnected.
- the first mobile entity 111 may take appropriate actions concerning the first indication relating to the first group affiliation, e.g. re-generate the first indication based on those indication relating to group affiliations that are still valid, e.g. there is a corresponding established connection.
- the first mobile entity 111 initiates generation, based on the first and second identity tokens and the first and second indications relating to the first and second group affiliations, respectively, of a group affiliation token, denoted ‘gr. aff. tkn’ in the Figure.
- the group affiliation token indicates that the first mobile entity 111 is affiliated with at least the second mobile entity 112 due to detection thereof.
- the first mobile entity 111 generates the group affiliation token.
- initiation of the generation may mean that the first mobile entity 111 sends a request to the server 120, which instructs the server 120 to generate the group affiliation token to be sent back to the first mobile entity 111, see actions A071 to A073 below.
- the request, or message may then comprise the first and second identity tokens and the first and second indications.
- the generation of the group affiliation token uses the abovementioned algorithm that is known to each mobile entity 111, 112 of the system 100, and in some examples involving the server 120, the algorithm also known to the server 120.
- the algorithm may be predetermined, such as configured, hardcoded or the like, or the algorithm may be configured upon registration for becoming part of the system 100, i.e. the eco system implementing the embodiments herein.
- the group affiliation token is generated based on the identity tokens of at least two mobile entities that have detected/identified each other, see action A010 and A020.
- a mobile entity may store the received identity token(s) in order to keep track of re- detection/re-identification of mobile entities that the mobile entity previously has detected/identified. Consequently, enabling the duplicity check in action A055 and A065.
- storing of the group affiliation token can be advantageous in order to save computing resources when a mobile entity first has identified one other mobile entity and then a further mobile entity. This means that the mobile entity first collaborates with one other mobile entity and then upon identification of the further mobile entity, with two other mobile entities. If the group affiliation token(s) are stored, the mobile entity may revert to the group affiliation token (generated and stored upon identification with said one other mobile entity) when connection/detection/identification of the further device is lost without any need for recalculation of said group affiliation token. Similarly, if the group affiliation token, associated with these three mobile entities, is stored, such group affiliation token may easily be retrieved and set as an active group affiliation token, when the further mobile entity is detected again.
- the first/second indication relating to group affiliation comprises, or is, the active group affiliation token “active” may here refer to that such active group affiliation token is to be sent in response to detection, e.g. as opposed to any group affiliation tokens stored for the purpose of re-use and/or reduction of calculations.
- action A070 of the first mobile entity 111 means that the first mobile entity 111 sends the request to the server 120
- the server 120 may receive the request.
- the request may comprise the first and second identity tokens and the first and second indications.
- the server 120 may generate, based on the first and second identity tokens and the first and second indications relating to the first and second group affiliations, respectively, a group affiliation token.
- a group affiliation token typically, either the first mobile entity 111 or the server 120 generates the group affiliation token.
