## Title
Methods, apparatuses, and computer program products for maintaining of security and integrity of image data

## Abstract

A user interface for masking portions of an image is provided. A controller included in the user interface is arranged for receiving a request for an image, determining whether access settings associated with selected portions of the image are fulfilled, and providing image data representing said image in response to determining that the access settings are fulfilled.

## Background
FIELD
The present application relates to a user interface, a device and a method for improved maintaining integrity, and in particular, to a user interface, a device and a method for improved maintaining of integrity for image sharing.
BACKGROUND
More and more electronic devices such as mobile phones, MP3 players, Personal Digital Assistants (PDAs) and computers both laptops and desktops are being used to browse the internet and to upload and share images via applications that make these images available on the internet. These applications generally make these images available to a large number of persons, much larger than is known to the user uploading these images. Some images may contain data or other information that may be regarded as sensitive and is not something that the user would like everyone to see as it would seriously infringe on either the uploader or an acquaintance of the uploader's personal integrity or even security.
Some applications offer the user an opportunity to restrict access to the images to certain groups or persons. This has a disadvantage in that the restrictions become very limited and are not flexible and are usually applied to a whole series of images instead of a single image. This requires that the user carefully selects and arrange his images in albums which are assigned a certain security level or access rights criteria. This makes it further difficult for a user browsing these images as that user has to browse through multiple albums to see all the images they are allowed to access.
A device that allows fast and easy access as well as opportunities to restrict access to images that are to be shared or accessible through the device or user interface would thus be useful in modern day society
SUMMARY
On this background, it would be advantageous to provide a user interface, an apparatus and a method that overcomes or at least reduces the drawbacks indicated above by providing an apparatus according to the claims.
Further objects, features, advantages and properties of device, method and computer readable medium according to the present application will become apparent from the detailed description.

In one embodiment the screen shot view is a view of an application window. It should be understood that the choice of the size of the screen or the application window is dependant on a number of design issues such as total device size, purpose of the application as well as user preference.
In this embodiment an image 410 is displayed, see FIG. 4a. In one embodiment the image is about to be uploaded to a server by a user and in one alternative embodiment the image has already been uploaded to a server. In one embodiment the server is also operating as a client in a network.
A group of four persons 420a-d is shown on the image 410. One of the persons 420a has expressed wishes to not be publicly shown as being part of the group. The reasons for this wish can be any of a great number of possibilities all relating to personal integrity issues or even security issues and the reasons for this wish will not be discussed further herein.
A controller is arranged to receive a selection of at least a portion of the image data and to assign an access criterion to that portion.
In FIG. 4b a user has made a selection of a portion 415 of the image 410. In this example the portion 415 overlaps with the face of person 420a. 
In this embodiment the selection is marked by a circle being displayed around the selection 415.
In one embodiment the selection is made by marking the portion using a pointing tool such as a cursor controlled by a mouse or navigation buttons or if a touch display is used by a stylus.
In one embodiment the selection is made using a lasso tool as is known from computer software such as Adobe Photoshop®.
In one embodiment the selection is made by marking the center (or other position) of a selection mask. Upon marking the center a portion of the image surrounding this marked center is then selected.
In one embodiment a controller (not shown) is arranged to display a pop-up window or pop-up box 430 that provides a user with access right options, see FIG. 4c. In this example a list of N options are displayed and a user has marked one option (Option 2) for selection.
In one embodiment the options correspond to levels of security or integrity. A higher level gives access to fewer persons or groups than a lower level.
In one embodiment the options correspond to users. In such an embodiment the option list is a list of friends or other contacts.
In one embodiment the options correspond to groups or networks of persons. Example of such groups can be friends, colleagues, friends of friends etc. and depend on the capabilities of the application handling the images. For example, in one embodiment all client devices associated with a given network domain name may be a group.
In one embodiment a controller (not shown) is arranged to provide user with means to create new options as needed. Consequently, user may define a default list of options comprising the options he/she typically uses.
In one embodiment the access setting options are inclusive, i.e. they comprise a list of persons or groups that have access to the selected portion.
In one embodiment the access setting options are exclusive, i.e. they comprise a list of persons or groups that do not have access to the selected portion.
In one embodiment the access setting can be set so that no-one except the owner has access to the selected portion.
In one embodiment the options correspond to a specified password that a viewer will be prompted to input to view the selected portion 415. Selecting a password will cause the controller to display an input field for the password to be given. In one embodiment the password has been given before hand and need not be given again or it will only be displayed for user confirmation.
It should be noted that in one embodiment the access rights options are set to a default value which can be set by a user. Such default values can be set for an album, for a user or for a device. This allows a user to specify access rights that are to be used for all selections made in a series of images.
In one embodiment the access rights settings shown in the pop-up box 430 is a series of default values of which the user can select one or more that are appropriate.
In one embodiment the controller is arranged to display the options in a list adjacent the image or in a separate application window or field (not shown).
In one embodiment the controller is arranged to store the access settings for the image 410 along with the image or alternatively in a package comprising both the image data and the access settings.
The controller is also arranged to upload these access settings along with the image data or alternatively separately. The latter is especially useful if the image data has already been uploaded.
Also, in one embodiment the actual image database and access settings database may be logically separated (with some implementations these databases may be physically separated as well). In such an embodiment the controller is arranged to store/upload the image data and access settings separately.
It should be noted that multiple selections can be made for one image and each selected portion may have its own access setting or they may be common to the image.
FIG. 4d shows a screen shot view of the image as it will be displayed to a person lacking the access right to view the selected portion 415 of the image 410.
FIG. 5 shows a display view 503 or alternatively an application window 503 on an apparatus. In this example an image 510 is displayed.
In the exemplary description steps that might be displayed are still shown and described to fully explain the procedure or method performed. Which steps that are actually displayed depend on the implementation and the options chosen by both the user and the designer.
In FIG. 5a an image is displayed with two masked portions 515 and 516. One being the driver's face (515) and the other being the registration number (516). In this embodiment the masking is achieved by completely whitening out the portions 515 and 516.
In other embodiments other maskings may be used such as blurring, blacking out, partial blacking out, inverting colors, stripings etc., textures such as image sharing service's logo etc. In some embodiments user may be given possibility to select which masking is used.
A controller is arranged to check the access settings in relation the user requesting the image and if it is determined that the user is allowed to view the masked portion 515 the image is displayed without the masking.
In one embodiment the image data is downloaded along with the access settings and the determination is performed locally.
In one embodiment the request for the image is uploaded along with a user identification and a controller determines whether the user identification correspond to the access setting. Image data corresponding to the user identification's correspondence with the access setting is then downloaded to the requestor.
In one embodiment the user identification is requested upon determination that the image is associated to an access setting. In one embodiment the user identification is the password.
In this example the two portions 515 and 516 have different access settings and the user identification provided is only determined to satisfy or correspond to one of the access settings.
FIG. 5b shows the image 510 being displayed with one of the portions 516 still being masked and the other portion 515 being displayed unmasked. In this image the face of the driver is thus visible, but the registration number is still masked.
FIG. 6 shows a flow chart of a method according to the teachings herein. In a first step 610 a selection of a portion is received. A controller is arranged to determine access settings corresponding to the selected portion in step 620 and to store or upload these access settings in step 630.
FIG. 7 shows a flow chart of a method according to the teachings herein. In a first step 710 a request for an image is received. In a second step 720 a controller is arranged to determine whether access settings corresponding to a portion of the image is fulfilled or satisfied. If so the controller is arranged to provide image data corresponding to an image with the portion visible and in step 730A. If not the controller is arranged to provide image data corresponding to an image with the portion masked in step 730B.
In one embodiment the access settings are inclusive, e.g. they comprise a list of persons or groups that have access to the selected portion.
In one embodiment the access settings are exclusive, e.g. they comprise a list of persons or groups that do not have access to the selected portion.
In one embodiment the access settings are dynamic. In one embodiment a controller is arranged to receive instructions indicating that the access settings should be changed.
In one embodiment a user viewing an image may input a request to propose a change to the access settings by suggesting that a person or group should either be included or excluded from having access to the selected portion.
In one embodiment the owner of the image decides whether to update the access settings or not. In one embodiment the user is provided with a notification that such an access setting changing request has been received and the user is prompted to decide whether to allow it or not.
In one embodiment the request is to be voted upon and each user viewing the image and having access to a selected portion is provided with a notification of the pending access setting changing request and a prompt whether to vote in favor or not of the change. Such a vote can either be partial or complete.
In one embodiment all users having access to a selected portion are notified of a pending request regardless of whether they are viewing or have viewed the corresponding image. Such a notification can be given either by a sent message or upon a notification next time the application is started.
FIG. 8 shows a schematic view of a server and several clients acting and cooperating according to an embodiment. It should be noted that client A and the server may be implemented by the same apparatus.
A client A shares an image having access settings associated with a selected portion of the image by uploading it to a server (1). The server is later requested by a client B to view the image (2). Client B satisfies the access settings and is thus provided with a copy of the image and a view of the access settings (3). Client B sends a request to change the access settings by including a further user, Client C (4). The owner, client A is thereby notified about the request (5) and so are the other users satisfying the access settings (6). The other users vote (7) and the access settings are updated accordingly and the owner is notified accordingly (8). Alternatively the added client C is also notified (9). As can be seen Client F not having any access rights is left out of the communications sent between the server and the other clients.
Client F is notified of his access rights first when he sends his own request (10).
It should be noted that the apparatuses described above may act as a server in a network, as a client in a network or both.
