Methods and systems for tracking image senders using client devices are described herein. A computing system may receive an image containing a first watermark vector corresponding to a user account of an image sender. The computing system may convert the image to a frequency domain image that contains the first watermark vector. From the frequency domain image, the computing system may identify the first watermark vector. The computing system may compare the first watermark vector to each of a plurality of stored watermark vectors, each corresponding to a known user account, to determine a probability of a match. The computing system may determine the user account of the sender of the image by determining which of the plurality of stored watermark vectors has a highest probability of a match, and may send, to a workplace administrator platform, an indication of the user account.

If an image read by an image reading unit is formed by an image forming unit, a control unit synthesizes a first encoded image and a second encoded image with the image formed by the image forming unit to generate a synthetic image, the first encoded image representing encoded data where reading setting information used for the image reading unit to read the image is encoded, the second encoded image representing encoded data where forming setting information used for the image forming unit to form the image is encoded, the first encoded image being synthesized at a position where a direction in which the document is read by the image reading unit is specifiable, and the second encoded image being synthesized at a position where a direction in which the image is formed on the sheet is specifiable. The image forming unit forms the synthetic image on the sheet.

In an embodiment, a UE determines QCL information that indicates an association between a spatial parameter and a current transmission configuration, and conveys the determined QCL information to a BS. In another embodiment, a BS transmits a DCI that triggers transmission of a reference signal that includes QCL information that indicates an association between a spatial parameter and a current transmission configuration, whereby any DCI triggering any reference signal that includes any QCL information is configured to trigger a UE to send an express acknowledgment or an implied acknowledgment to that DCI.

Methods and systems for creating a security mark for a document. A first generation print can be rendered based on one or more patterns (e.g., pantograph pattern) for a security mark. Post-copy results of the pattern(s) can be then rendered. The first generation print and the post-copy results of the pattern(s) can be calibrated, and the output of the calibration of the first generation print and the post-copy results are then applicable for optimizing the design of the security mark for a print condition. Optimization of the design of the security mark for the print condition can be implemented by applying the output of the calibrating of the first generation print and the post-copy results for the print condition. The first generation prints and post-copy results of pantograph pattern samples can be calibrated to drastically reduce the time and labor involved in optimizing void pantograph designs for a particular print condition.

An image forming apparatus generates embedded information for uniquely identifying a page, for each page of a document, prints the document while embedding the embedded information into the document, and registers a set of pieces of the embedded information in a blockchain service. The image forming apparatus thereby verifies whether the printed product is a correct printed product.

Scannable thumbnails for identifying data objects stored on a database. A method includes identifying a data collection comprising one or more data objects stored on a database and receiving a thumbnail selection to represent the data collection, wherein the thumbnail selection comprises one or more of an image from the data collection, a graphic, or text. The method includes generating a scannable code associated with the data collection merging the scannable code with the thumbnail selection to generate a scannable thumbnail.

A printing apparatus is provided. The printing apparatus includes a processing circuitry configured to generate embedding data to be embedded in a print image to be printed out; divide the print image into two or more areas, and embed the embedding data in each of the two or more areas in such a way that placement of the embedding data is identical in each of the areas; and output the print image in which the embedding data is embedded.

The disclosure discloses methods and systems for securing documents submitted for scanning at a device such as a multi-function device. The method includes scanning a document received from a user. A user interface is provided to the user to define a document type and to further define an access level for accessing the scanned document. Then, scanned data is generated. The scanned data is encoded based on a unique identity of the device and based on the access level such that the scanned data is accessible by the user and/or by one or more other users according to the defined access level. Finally, the scanned document is generated. Later when the scanned document is accessed by any user, details of the user accessing the scanned document is matched with details added in the encoded scanned data. Based on matching, the user is allowed to access the scanned document.

An apparatus detects a transient thermal gradient in a substrate. The apparatus is comprised of an electromagnetic radiation source configured to emit source electromagnetic radiation; a fast shutter configured to block the source electromagnetic radiation when closed, and open in response to a command to pulse the source electromagnetic radiation; a substrate support that supports a substrate disposed to emit a pulsed radiation from a back side of the substrate when the source electromagnetic radiation is pulsed through the substrate; and a detector configured to face the back side of the substrate. The detector is used to detect a transient thermal gradient in the pulsed radiation.
