A method for inferring user activity statistics includes receiving job logs of a device infrastructure. Each job log including job information for a job performed for one of a set of users by one of a plurality of shared devices. A job descriptor is generated for each job based on the job log. The job is assigned to one of a set of defined job types based on the job descriptor. An activity matrix is composed where activity of each user for each of a plurality of time periods is represented as a fixed-length vector representing at least some of the job types. Each index of the vector is derived from a count of one job type for the user in that time period. The activity matrix is decomposed into first and second factor matrices to minimize an overall reconstruction error. User activity statistics are output based on the decomposition.

The present invention relates to a mobile terminal providing an image printed out through a photo printer and related information, and a method of controlling the same. The mobile terminal includes a memory, a camera, a display; and a controller configured to cause the display to display a preview image of image data received via the camera and cause the display to display an indicator indicating that an image object included in the preview image corresponds to a specific image stored in the memory when the image object corresponds to the specific image, wherein the specific image has been previously printed out via a printer device.

A method, system, and processor-executable software for processing images or video captured by a smartphone or other digital image capture device for subsequent validation and authentication captures not only the image, but also metadata relevant to the authenticity of validity of the image, such as position, time, camera movement and orientation, image parameters, and so forth. The image is watermarked and both the watermarked image and the metadata, as well as a symmetric key used in the watermarking, are digitally signed and transmitted or uploaded to a web server or authentication centric entity for authentication and storage. When a third party submits an image to the web server or authentication centric entity, the submitted image is compared with the stored watermarked image for authentication and validation of the submitted image, and the metadata is then retrieved to enable analysis of the contents of authenticated and validated image.

A method and apparatus for processing metadata of an image are disclosed. The metadata is associated with the image and an applet views the metadata in response to selection of the image. The metadata may include links to websites, audio files, video files, and text files, as well as image capture information including GPS location, time and date of capture, camera settings, etc. In response to selection of the image, or in response to arriving at a website pointed to by a URL in the metadata, a list of information materials associated with the image may be displayed. One or more of the information materials may be automatically activated.

A device comprising: an input for receiving images captured by a camera, of an environment illuminated by light from a light source; an image processing module; and a verification module. The image processing module is configured to process one or more of the images to decode a timestamp modulated into the light, and to output an indication of the decoded timestamp. The verification module is arranged to receive the indication of the decoded timestamp output by the image processing module, and based thereon to perform an at least partially automated verification of a time at which the one or more images were captured.

A document ID is recorded in an operation log, and an operation ID and document ID are recorded in a job log. The job log and operation log are set such that they can be searched in association with each other. An operation log record associated with a designated document record is read and added to a result list (S2104). Operation log records are read out one by one from the result list. If an associated document ID is found, it is added to a target document ID (S2109). Further, an operation log record associated with the found document ID is added to the result list (S2104).

A transmission job for transmitting image data is executed. A report indicating a result of transmission of the image data is output. A first instruction regarding output of the report is accepted as a common setting for a plurality of transmission jobs. A second instruction regarding output of the report is accepted as an individual setting for a specific transmission job. Control is performed so as to output the report if the second instruction indicates that the report is to be output, even if the first instruction does not indicate that the report is to be output.

Disclosed is a technique for allowing proper classification information to be provided to an edited image. When it is determined that the editing is cropping, a system controller cuts a decompressed image down to a desired size using an image processor and performs face detection on a crop image. The system controller generates a header for image data of an edited image. When the setting of automatically providing classification information is ON, classification information is automatically provided based on the detected face information.

In a case where an image forming apparatus is connected to an information processing apparatus, correction information is generated through comparison between time information obtained by the image forming apparatus and time information obtained by the information processing apparatus. The image forming apparatus transmits, to the information processing apparatus, time information indicating a time at which setting information is updated in the image forming apparatus. The information processing apparatus corrects the received time information with the correction information. The information processing apparatus determines whether to update setting information stored in the information processing apparatus with received setting information, based on the corrected time information.
