Abstract

The user of a mobile entity with camera functionality uses it to capture an image item which the user then transfers to a networked service system for future access. To facilitate the sharing of the image item with persons who were nearby when the image item was captured, the user uses the mobile entity to form a viewer set of permitted viewers of the image item. The process of forming the viewer set involves the user selection of individuals from a group of persons identified as nearby by a wireless enquiry carried out by the mobile entity contemporaneously with image-item capture. Each viewer in the viewer set is then sent a message with access information for accessing the image item at the service system.

Claims

1. A method of sharing an image item comprising, without regard to order or overlap,:

(a) capturing an image item using camera functionality of a mobile entity and transferring the image item to a networked service system;

(b) forming, at the mobile entity, a viewer set of at least one intended viewer of the image item, by a process comprising selection from a group of persons identified by wireless means as nearby contemporaneously with image-item capture in step (a); and

(c) sending, to the or each viewer in the viewer set, a message comprising access information for use in accessing the image item at the service system.

2. A method according to claim 1, wherein identification of the group of persons nearby contemporaneously with image-item capture, is effected by a wireless enquiry sent out by the mobile entity.

3. A method according to claim 2, wherein said wireless enquiry is effected at the same time as the image item is captured.

4. A method according to claim 2, wherein said wireless enquiry is such as to restrict said group of persons identified as nearby to persons who lie in the same general direction from the mobile entity as that in which said image item was captured.

5. A method according to claim 2, wherein said wireless enquiry is effected by short-range communication between the mobile entity and devices carried by nearby persons.

6. A method according to claim 2, wherein said wireless enquiry comprises the mobile entity asking a location server to identify persons who are currently nearby as indicated by the location of associated mobile devices.

7. A method according to claim 1, wherein the selection from said group is effected by a user of the mobile entity.

8. A method according to claim 1, wherein the selection from said group is effected automatically according to predetermined criteria.

9. A method according to claim 1, wherein said image item captured in step (a) forms a member of an image set to which at least one further image item, captured before or after the first-mentioned image item, is added automatically if captured within a specified locality;

said access information sent to the or each viewer in the viewer set being usable for accessing all image items of said image set.

10. A method according to claim 9, wherein said specified locality is specified in terms of a distance from the location at which the first-mentioned image item was captured.

11. A method according to claim 9, wherein said specified locality is specified in terms of a distance from the location at which the image item most recently added to the image set was captured.

12. A method according to claim 9, wherein steps (a) to (c) are repeated in respect of a said further image item whereby to form a further viewer set, independent of that formed for the first-mentioned image item, with the or each viewer in this further viewer set being sent access information independently of the corresponding information sent in respect of the image set that includes the said first-mentioned image item.

13. A method according to claim 9, wherein steps (a) and (b) are repeated in respect of a said further image item whereby to form a further viewer set which is combined with the viewer set for the first-mentioned image item to form an expanded viewer set, said access information being sent to the or each viewer in the expanded viewer set.

14. A method according to claim 1, wherein said image item captured in step (a) forms a member of an image set to which at least one further image items, captured before or after the first-mentioned image item, is added automatically if captured within a specified time period;

said access information sent to the or each viewer in the viewer set being usable for accessing all image items of said image set.

15. A method according to claim 14, wherein said specified period is specified relative to the time at which the first-mentioned image item was captured.

16. A method according to claim 14, wherein said specified period is specified relative to the time at which the image item most recently added to the image set was captured.

17. A method according to claim 14, wherein steps (a) to (c) are repeated in respect of a said further image item whereby to form a further viewer set, independent of that formed for the first-mentioned image item, with the or each viewer in this further viewer set being sent access information independently of the corresponding information sent in respect of the image set that includes the said first-mentioned image item.

18. A method according to claim 14, wherein steps (a) and (b) are repeated in respect of a said further image item whereby to form a further viewer set which is combined with the viewer set for the first-mentioned image item to form an expanded viewer set, said access information being sent to the or each viewer in the expanded viewer set.

19. A method according to claim 1, wherein a placeholder for the image item is sent to the service system immediately following capture of the image item, the image item itself being subsequently transferred to the service system.

20. A method according to claim 19, wherein said placeholder comprises a reduced resolution version of at least a part of the image item.

21. A method according to claim 19, wherein said placeholder comprises the time and location of capturing of the image item.

22. A method according to claim 1, wherein in step (c) the or each said message is sent by the mobile entity.

23. A method according to claim 22, wherein the access information comprises contact data for contacting the service system and an identifier of the image item captured in step (a) or of an image set containing that item, the mobile entity providing this identifier to the service system when transferring the image item to the latter.

24. A method according to claim 22, wherein the access information comprises contact data for contacting the service system and a hash of the image item captured in step (a), the method comprising the further step of the service system forming a hash of the image item and using this hash as an identifier by which a said viewer can identify the item for retrieval.

25. A method according to claim 1, wherein in step (c) the or each said message is sent by the service system, the mobile entity providing the service system with the viewer set in association with the image item captured in step (a) or an identifier thereof.

26. A method according to claim 25, wherein the access information comprises contact data for contacting the service system and an identifier of the image item captured in step (a) or of an image set containing that item.

27. A method according to claim 25, wherein the access information comprises contact data for contacting the service system and an identifier of the image item captured in step (a), the identifier comprising a hash of the image item formed by the service system.

28. A method according to claim 1, wherein the access information includes a password.

29. A method according to claim 1, wherein the mobile entity forms a hash of the image item captured in step (a) and sends this hash to the or each viewer in the viewer set, the method further comprising the step of a said viewer using the access information to retrieve the image item from the service system and checking the integrity of the image item so retrieved by forming a hash therefrom and comparing it with the hash received from the mobile entity.
