## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is related to U.S. patent application Ser. No. 11/752,390, entitled FEE-BASED DISTRIBUTION OF MEDIA BASED ON DEVICE PROXIMITY, filed May 23, 2007, by Fowler et al. This related patent application is herein incorporated by reference in its entirety.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to data processing. More specifically, the invention relates to controlling access to digital images based on device proximity.
2. Description of the Related Art
The technologies of digital cameras and the Internet have been widely adopted by consumers. As a result, there is a growing demand for the sharing of digital photographs and video (hereafter referred to as “digital images”). One solution is provided by websites that host digital images, such as Flickr®, Snapfish®, Yahoo Photos®, and the like. Many image hosting websites enable a user to define an access list, which specifies the people who are authorized to view a particular group of digital images.
Typically, the user creates an access list by manually inputting the people who are authorized to access the digital images. Once the digital images are posted on the website, people on the access list may access the digital images from the website. However, this process is not always a practical method of creating an access list. In some situations (e.g., weddings, parties, public events, etc.), there may be a large number of people who may wish to access the digital images. In such situations, the manual input method of creating an access list is often labor-intensive and inefficient.
Therefore, there is a need in the art for techniques for controlling access to digital images.
SUMMARY OF THE INVENTION
The present invention generally relates to data processing. More specifically, the invention relates to controlling access to digital images based on device proximity.

FIG. 1 is a block diagram illustrating a computing and data communications environment 100, according to one embodiment of the invention. As shown, the environment 100 includes an imaging device 110, wireless devices 120, a wireless repeater 130, a cellular network 140, and a cellular device 150. The imaging device 110 includes a set of images 114 and a set of identifiers 116. Illustratively, the imaging device 110 may be any device for capturing digital images, such as a digital camera, a video camcorder, or a cellular telephone equipped with a camera.
In one embodiment, the imaging device 110 is configured to send an invitation signal 160 and to receive a response signal 170. The invitation signal 160 includes an invitation for other people to be provided access to an image (e.g., one of the images 114 captured by the imaging device 110) once it is placed in a shared location, such as a hosting web site. In one embodiment, the invitation signal 160 includes an invitation message and a network identifier for the imaging device 110. The invitation message may be configured in a variety of techniques. For example, the invitation message may be formatted in plain text or in Extensible Markup Language (XML). In addition, the invitation signal 160 may include any other relevant information, such as the type of imaging device (e.g., camera, video recorder, cellular telephone, etc.), the quality of the image (e.g., resolution, aspect ratio, bit rate, etc.), a description of the content of the image (e.g., “People,” “Scenery,” etc.), a time stamp for the image capture, and the like. In one embodiment, the invitation signal 160 may be sent after an image is captured and added to the set of images 114. In another embodiment, the invitation signal 160 could be sent periodically (e.g., once every five minutes). In yet another embodiment, the invitation signal 160 could be sent whenever the user of the imaging device 110 manually triggers an invitation (e.g., by activating a manual control). The invitation signal 160 may correspond to a single image or to a group of images.
In one embodiment, the invitation signal 160 is broadcast generally, and can be received by any wireless devices 120 that are within range of the transmission. Alternatively, the invitation signal 160 may only be addressed to a pre-selected list of devices. The pre-selected list of devices could be loaded onto the imaging device 110, and may limit the invitations to, for example, the friends of the imaging device owner. The imaging device 110 may include profiles to classify the types of images being captured and to specify which people may be invited to share each type of image. For example, a “Family” profile may be used to classify images of family members, and the corresponding invitations could be restricted to devices belonging to family members. Another profile named “Scenery” may be used to classify images that do not include people, and the corresponding invitations signals 160 could be broadcast to any devices in range. In one embodiment, the profiles can be manually selected on the imaging device 110 prior to the image capture. Alternatively, the imaging device 110 may include a component configured to recognize human faces in an image, according to techniques known in the art (e.g., pattern recognition techniques). If any human faces are detected in an image, the image may be automatically assigned an appropriate profile, for example “People.” In one embodiment, where the signal is sent to selective users/devices, the signal may include a password. The password is used to access a media hosting computer, such as the server computing device 220 described in more detail below.
In one embodiment, the wireless devices 120 can be configured to alert the user to the receipt of an invitation signal 160, to present the user with the option for accepting the invitation, and to transmit a response signal 170 back to the imaging device 110. The wireless devices 120 may also incorporate profiles to classify any incoming invitation signals 160, including rules for how to handle each profile. The profile rules could specify whether to automatically accept or reject an invitation, and thus not require any intervention by the user. The profile rules can be based on the source of the invitation (e.g., only accept invitations from designated friends), or may be based on other information included in the invitation (e.g., only accept invitations for images of people, only accept high-resolution images, do not accept images taken with cellular telephone cameras, etc.).
In the case that the invitation is accepted, the wireless device 120 issues a response signal 170. The response signal 170 includes an identifier unique to the user of the wireless device 120. In one embodiment, the identifier is the email address of the user. The response signals 170 are received by the imaging device 110. The identifiers included in the response signals 170 can then be added to the set of identifiers 116, which are stored in the imaging device 110. Each identifier 116 may be configured to reference, for example, a specific invitation signal 160, a specific image 114, a group of images 114, and/or a particular period of time. The imaging device 110 can be configured to apply rules to the received response signals 170. For example, the imaging device 110 may include a rule to only store identifiers for a pre-selected list of friends. When the set of images 114 is uploaded from the imaging device 110 to a hosting web site, the set of identifiers 116 is also uploaded. The uploaded identifiers are used to construct an access list. Thereafter, the people included in the access list are notified (e.g., by email), and are authorized to access the images.
The wireless devices 120 could include any device configured to receive and respond to an invitation signal, including cellular telephones, portable computers, cameras, etc. It may also be useful to construct devices having the sole purpose of responding to invitation signals 160. Such single-purpose devices could be configured in a small and unobtrusive form, for example a key chain fob.
In some situations, a person may wish to send a request for images to owners of imaging devices. Such situations may include, for example, a person who does not have an imaging device, or a person who may want images captured by higher-quality imaging devices, by more skilled photographers, or from a better vantage point. Thus, rather than waiting for an invitation signal 160 to be sent by the imaging device 110, the user of the wireless device 120 may wish to proactively ask others to capture images on his behalf. In one embodiment, a wireless device 120 (the “requesting wireless device”) could be configured to broadcast a request signal (not shown) to any imaging devices 110 (the “requested imaging device(s)”) in the area. The request signal includes an identifier, similar to the identifier included in a response signal 170. When received, the request signal could cause the requested imaging device 110 to display a message requesting images. The request message could comprise a display of a text message, a warning light, an auditory alert, or some other notification scheme. The owner of the requested imaging device, upon receiving a request message, can decide whether to fulfill the request. If the owner decides to fulfill the request, the requested imaging device 110 may add the identifier contained in the request signal to the set of identifiers 116. As a result, the user of the requesting wireless device 120 is added to the access list for the images.
In one embodiment, the signals 160, 170 are short-range wireless signals, such as those that conform to the Bluetooth wireless network protocol. By virtue of using a short-range wireless signal, the invitation signal 160 is only received by wireless devices 120 in proximity of the imaging device 110. Thus, the invitation signal 160 is only received by those people who are most likely to be interested in receiving the digital image, namely, the people who are in the same area at the same time as the image is captured.
In some situations, it may be useful to extend the invitation signal 160 to a greater range than that afforded by a short-range wireless signal. This extension can be performed by use of a wireless repeater 130, according to one embodiment. The wireless repeater 130 illustrates a device that is configured to repeat (i.e., receive and transmit forward) the invitation signal 160 to other wireless devices, as well as to repeat any response signals 170 back to the imaging device 110. Thus, the wireless repeater 130 may serve to extend the range of the invitation signal 160. The wireless repeater 130 could also serve as a wireless device 120. That is, the wireless repeater 130 can function to accept an invitation signal 160, as well as repeat the signal for other wireless devices 120 that were not in range of the original signal. However, if the invitation signal 160 is received and repeated by several wireless repeaters 130, it could be repeated too many times, and thus be propagated to a range that is too large to be useful. If so, the people receiving the invitation signal 160 may no longer be in the same area as the imaging device 110, and thus may not be interested in having access to the shared image. To avoid this situation, the imaging device 110 could be configured to enable the user to specify the maximum number of times that an invitation signal 160 can be repeated.
In some cases, a person present when an image is captured may wish to access the image, but may not be carrying a wireless device capable of responding to a broadcast invitation signal 160. To address this situation, a wireless device 120 may be configured to enable the device owner to accept an invitation on behalf of another person. More specifically, the owner of a wireless device 120 could enter or store more than one identifier in the device. Such a wireless device 120 could thereafter respond to a single invitation signal 160 with a plurality of response signals 170, each including a different identifier. By way of this technique, a person who is not carrying a wireless device 120 can still be added to an access list for viewing digital images.
In another embodiment, invitation and response signals are cellular telephone messages, rather than short-range wireless signals. As shown, the imaging device 110 sends an invitation message in a cellular invitation message 180, which is received by the cellular network 140. The cellular invitation message 180 may be a Short Message Service (SMS) text message, or any other cellular telephone protocol. The location of the imaging device 110 is determined by techniques known in the art. In one approach, the imaging device 110 includes a Global Positioning System (GPS) component (not shown), which is configured to include the location of the imaging device 110 in the cellular invitation message 180. In another approach, the location of the imaging device 110 is determined by triangulating the cellular invitation message 180 from cellular transmission towers (not shown). The location of the imaging device 110 is determined by the cellular device locator 145, which can then determine any cellular devices 150 in the vicinity of the imaging device 110. A secondary invitation message 190 can then be sent to the nearby cellular devices 150. If the invitation is accepted, the accepting cellular device 150 sends a cellular response message 185 to the imaging device 110. As with the wireless devices 120, the cellular device 150 can be configured to send a response automatically, or the response can be manually triggered by the user. Similarly to the response signals 170, the cellular response messages 185 include identifiers which can be added to the set of identifiers 116 stored in the imaging device 110. The identifiers can be filtered, and are thereafter utilized to construct an access list in the same manner as described above for the response signals 170.
FIGS. 2A-2B illustrate a block diagram of a computing system 200 for controlling access to digital images, according to one embodiment of the invention. The computing system 200 includes a client computing device 210, a server computing device 220, and the imaging device 110 illustrated in FIG. 1. The client computing device 210 includes a client application 212 (e.g., a web browser). It is contemplated that the client computing device 210 may be one of the wireless devices 120, according to one embodiment. The server computing device 220 includes an image sharing application 222 (e.g., a web application) and other resources 221. The image sharing application 222 includes an access controller 224, an access list 226, and a set of shared images 228. The other resources 221 represent any server applications (other than the image sharing application 222) that may be made available to a user of a client computing device 210, for example image editing applications, communications applications, word processing applications, etc.
As shown in FIG. 2A, the set of identifiers 116 and the set of images 114 are uploaded from the imaging device 110 to the image sharing application 222. The uploaded images 114 are added to the set of shared images 228, and the uploaded identifiers 116 are added to the access list 226. The persons included in the access list 226 may be notified of the location of the shared images 228. In the case where the identifiers 116 include email addresses, the notifications may be emails generated by the image sharing application 222. The notification may include the network address of the image sharing application 222 (e.g., web address) and the password assigned to the notified user.
For the sake of simplicity, FIG. 2A illustrates the identifiers 116 and the set of images 114 as being separate objects stored within the imaging device 110. However, in one embodiment, each image 114 may include the corresponding identifiers 116. More specifically, each image 114 may be a data object that includes metadata storing the identifiers 116 for the users who may access that particular image 114. Once an image 114 is uploaded to the image sharing application 222, the identifiers 116 may be extracted from the metadata included in the image 114.
FIG. 2B illustrates the computing system 200 in the event that a user is using the client application 212 to connect to the image sharing application 222 in order to view the shared images 228. In one embodiment, the user is asked for his identifier (i.e., email address) and password. The access controller 224 determines if the user attempting a connection is a valid member of the access list 226, and if he has provided a valid password. The password may have been provided to the user in the invitation signal 160 sent by the imaging device 110, as noted above. If the user provides a valid identifier and password, he is allowed to view a shared image 228 corresponding to his identifier. It also contemplated that the user may be allowed to view a sub-set or the entire set of shared images 228, or to gain access to other resources 221 on the server computing device 220. Of course, the example described above with reference to FIGS. 2A and 2B is for illustrative purposes only, and is not intended to limit the scope of the invention. It is contemplated that embodiments of the invention may not include all of the elements described above. For example, in other embodiments, the user may be asked to provide either an identifier or a password, or may be identified by some other means (e.g., a cookie, IP address, etc.).
FIG. 3 is a flow diagram illustrating a method 300 for controlling access to a digital images based on device proximity, according to one embodiment of the invention. The method 300 is described with respect to portable wireless devices, where at least one of the devices is capable of capturing a digital image (e.g., imaging device 110). The method 300 begins at step 310, by triggering the sending of an invitation. The triggering of the invitation can occur automatically (e.g., when imaging device 110 captures an image), or can be occur manually (e.g., by a user activation of a control). At step 320, the invitation to join an access list is sent by a first wireless device. In one embodiment, the first wireless device is capable of capturing a digital image (e.g., imaging device 110). The invitation may be a short-range wireless transmission (e.g., invitation signal 160), or may be a cellular message sent to devices in the same vicinity (e.g., cellular invitation message 180), according to one embodiment. Alternatively, the invitation may be performed by some other technique. It is contemplated that the invitation may be broadcast indiscriminately, or transmitted only to selected devices (which may or may not be in the vicinity). In the latter case, the selected devices may be identified according to an invitation list resident on, or accessible by, the first wireless device.
At step 330, the invitation is received by a second wireless device in the same vicinity as the first wireless device (e.g., wireless device 120). At step 340, a response is sent from the second wireless device. The response can be sent by a manual command from the user of the second device, or can be sent automatically according to rules programmed in the second device. The response may be a short-range wireless transmission (e.g., wireless signal 170), or may be a cellular message (e.g., cellular signal 185), according to one embodiment. At step 350, the first wireless device receives the response sent by the second wireless device. The response contains an identifier that uniquely identifies the owner of the second device, such as an email address. At step 360, the responses received by the first wireless device are used to generate an access list (e.g., access list 226). The access list may be generated by the first wireless device, or may be generated by an external application (e.g., image sharing application 222). In one embodiment, all wireless devices responding to the request are placed on the access list. In another embodiment, a master access list (e.g., buddy list) is predefined as the list of approved devices that may accept an invitation issued by the first wireless device. The access list generated at step 360 then includes only a subset of the devices contained on the master access list. At step 370, the generated access list is used to notify the people in the list. The notification may be an email sent by an external application (e.g., image sharing application 222), according to one embodiment. The notification may include the location of the digital image files (e.g., a web link to a hosting web site), and any other information required to access the images, such as passwords, instructions, etc. At step 380, the access list is used to enable access to the digital images for those people identified on the access list. That is, any user attempting to access the digital images is first verified against the access list.
In the above examples, embodiments of the invention are described in terms of digital images. However, these descriptions are for illustrative purposes only, and in no way limit the scope of the invention. It is contemplated that embodiments of the invention may comprise other forms of content, for example audio recordings. Thus, more generally embodiments of the present invention are directed to any digital media including images, video, and audio content.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
