An image forming apparatus including a function including at least a print function includes a first authentication unit configured to perform authentication processing on local access to the image forming apparatus, a second authentication unit configured to perform authentication processing on remote access to the image forming apparatus, and a reception unit configured to receive separately a setting to activate multi-factor authentication processing including a plurality of authentication factors in the authentication of the local access and a setting to activate multi-factor authentication processing including a plurality of authentication factors in the authentication of the remote access. In a case where the multi-factor authentication processing for the local access is activated and the multi-factor authentication processing for the remote access is not activated, the activated multi-factor authentication processing for the local access is controlled not to be deactivated from the authenticated remote access.

Printing apparatus, method for controlling printing apparatus, and storage medium

An information processing apparatus configured to authenticate a user in first authentication processing and second authentication processing and permit the user who is authenticated to use at least one of a plurality of functions includes a control unit configured to, at a time of authentication of the user in the first authentication processing, perform control to prompt the user to select an authentication method to be used in the first authentication processing.

Information processing apparatus having multifactor authentication function, control method, and storage medium

An information processing apparatus is provided. The apparatus performs operations comprising performing facial authentication of a second user in a state in which a first user is logged in, performing authentication of a user using a second scheme that is different from facial authentication if the facial authentication is successful, and switching a logged-in user from the first user to the second user if the authentication using the second scheme is successful and the authenticated user is the second user.

Packaging bag and manufacturing method therefor

A printing apparatus determines a user who is logging into the printing apparatus as a job owner in a case where the printing apparatus receives print data through wireless communication in an access point mode.

Printing apparatus, control method of printing apparatus and storage medium, relating to determining an owner of print data

An apparatus and method is provided in which, in a setting of making user names case-insensitive, if a plurality of user names determined to be identical to a user name that is requested to log in is registered in an authentication database, log-in using the user name is not accepted.

Information processing apparatus, control method for information processing apparatus, and storage medium

An MFP (image processing apparatus) activates a specific AP by a software AP mode for using a setting service that allows an external apparatus to perform network setting to cause the MFP to connect to a network by the software AP mode. If the MFP receives, from a mobile terminal via a WLAN I/F, a connection request to the activated specific AP, the MFP executes processing to limit the number of external apparatuses (mobile terminals) that can connect to the specific AP to use a WLAN setting service. The MFP limits, for example, the number of the external apparatuses that can connect to the specific AP to one.

Image processing apparatus, control method thereof, and storage medium

An absorbent film and a substrate having extremely simple production without having an adhesive layer that can generate volatile components. The absorbent laminate contains a substrate, which has an inorganic material or a low-thermal-contraction organic material, and an absorbent film on the surface of the substrate. The organic material of the substrate has a rate of thermal contraction in the direction of conveyance thereof when performing hot pressing by means of a heating roller under the conditions of 140&#xb0; C., a roller pressure of 0.1 MPa, and a conveyance speed of 0.4 m/min of less than 0.6%. The absorbent film has an absorbent layer adhered to the surface of the substrate without an adhesive layer therebetween and containing less than 87 vol % and at least 25 vol % of a thermoplastic resin binder and over 13 vol % and no greater than 75 vol % of an inorganic absorption agent.

Absorbent laminate provided with absorbent film, electronic device containing same, and method for producing same

A semiconductor integrated circuit includes a phase-locked loop (PLL) circuit configured to generate an oscillation output signal synchronized with a reference clock and a plurality of clock and data recovery (CDR) circuits configured to adjust a phase of the oscillation output signal and a phase of serial data. The PLL circuit converts a voltage output from a loop filter, the voltage functioning to control an oscillation frequency of an oscillator, into a current and delivers the converted current to the plurality of CDR circuits. Therefore, in a case where clock signals used in a plurality of serial transmission channels are synchronized with one another, limitations on layout of clock wiring from the PLL circuit to the CDR circuits and the occurrence of jitter are reduced.

PLL circuit configured to distribute its loop control signal to CDR circuits

The invention provides a content addressable memory device having the capability of functioning as a content addressable memory device with a reduced memory capacity even when the device includes a large number of failed words in some memory blocks. To achieve the above object, the content addressable memory device according to the present invention includes a memory part including a plurality of memory blocks which can be controlled independently of each other, a failed memory block information memory for, when there is a failed memory block, storing address information associated with the failed memory block and outputting a signal indicating the failed memory block, and an encoder for, in accordance with the signal and an address input from the outside, outputting a memory block selection signal to the respective memory blocks to enable a memory block other than the failed memory block without enabling the failed memory block.

Content addressable memory device capable of reducing memory capacity

A DC-to-DC converter for zero-voltage or zero-current switching (soft switching). The converter minimizes noise and power losses when turning-on and turning-off switching devices. The converter includes a switching circuit, error amplifier, pulse-width modulator, differentiator and dead time adjusting circuit. The error amplifier compares an output voltage to a reference voltage and the pulse-width modulator adjusts the output pulse in accordance with the comparison result of the error amplifier. The differentiator outputs a differentiated signal dVSx/dt of the output voltage VS of the switching circuit, indicating over current flow in a switching device. The dead time adjusting circuit adjusts the dead time period to optimize the dead time period when it detects a peak in the differentiated signal dVSx/dt.
