Abstract: To inform a user that image data including an image of the user or the like is posted on a network, an information providing apparatus includes an acquisition unit for acquiring an action log including a history of a set of a user's positions and dates and times when the user was at the positions. The apparatus further includes a search unit for searching for image data that has been captured at a location and a date and time corresponding to a position of the user and a date and time included in the action log from image data posted on a network. The apparatus also includes a matching unit for detecting image data that includes an image relating to the user from pieces of image data found by the search unit.

Abstract: A private information management apparatus, a method, and a program that allows individual users to easily set and apply their privacy rules. A private information management apparatus receives setting data from a user terminal and creates a privacy rule that defines a condition for restricting disclosure of private information and a restriction method. If undisclosed image data contains private information of a user, the private information management apparatus extracts metadata contained in this undisclosed image data, and determines whether or not the metadata satisfies the condition for restricting disclosure of the private information. If it is determined that the condition is satisfied, the private information management apparatus executes the restriction method defined by the privacy rule.

Abstract: An information processing apparatus, method, and program product for appropriately setting confidentiality of a target electronic document even when copied data is pasted into a document from an electronic document including confidential information, without limiting replication from an electronic document including confidential information depending on attributes of the target electronic document.

Abstract: When a group of documents are received, the scan priority of the documents may be determined, according to one embodiment, by acquiring contexts about each of the documents and calculating a scan priority of each of the documents according to a combination of the contexts of the document. Then, each of the documents may be stored to a queue corresponding to the scan priority of the document, such that documents stored in a higher priority queue are processed before documents stored to a lower priority queue. Also, a confidentiality label may be assigned to each of the documents, starting with the documents in the highest priority queue first, based on content acquired from each of the individual documents.
