Patent application number | Description | Published |
20090070857 | COMMUNICATION APPARATUS - An authentication unit performs an authentication processing to obtain a permission for a physical interface including a driver to establish a connection to a network to perform a data transfer. A detecting unit detects authentication state information indicating a state of the authentication processing. Upon receiving the authentication state information from the detecting unit, a transmission control unit controls a transmission of data received from a module for performing a communication based on a protocol of an upper-level layer with respect to a data link layer to an external device based on the state of the authentication processing. | 03-12-2009 |
20090077187 | METHOD AND APPARATUS FOR COMMUNICATIONS - A communication apparatus working as a sub-device wirelessly transmits/receives encrypted data to/from a plurality of communication apparatuses working as main-devices. Upon detecting a plurality of connectable main-devices, the sub-device determines a target main-device for establishing communication based on priority of the detected main-devices. When the sub-device is disconnected from the main-device with which it is communicating, the sub-device automatically switches to another connectable main-device based on the priority of the detected main-devices. | 03-19-2009 |
20110075186 | IMAGE PROCESSING APPARATUS, METHOD PERFORMED BY IMAGE PROCESSING APPARATUS, PROGRAM PRODUCT, AND RECORDING MEDIUM THEREFOR - An image processing apparatus according to the present invention includes a sub communication unit that receives an association process request using wireless communication and executes an association process and includes a main communication unit that performs wireless communication in accordance with association information that is used in the association process and in accordance with setup information that is setting information on wireless communication that can be set for each system of the association process request. | 03-31-2011 |
20110231922 | COMMUNICATION APPARATUS, WIRELESS COMMUNICATION SYSTEM, AND METHOD OF SETTING ASSOCIATION INFORMATION - A communication apparatus includes a first communication unit that performs a wireless communication with two storage media that store therein association information for establishing a wireless connection and user identification information for identifying a user, respectively, and receives the association information and the user identification from the two storage media; a determination unit that performs user authentication based on the user identification information, determines whether or not to validate the association information based on the user authentication, and if the association information is determined to be valid, sets the association information; and a second communication unit that establishes a wireless connection based on the association information set by the determination unit. | 09-22-2011 |
20120240232 | QUARANTINE NETWORK SYSTEM AND QUARANTINE CLIENT - A quarantine network system includes a quarantine control apparatus and a quarantine client connectable with each other. The quarantine control apparatus includes a receiving unit to receive verification information of the quarantine client, an identification unit to identify a security policy that the quarantine client is required to conform to, and an inspection request unit to transmit an inspection request to the quarantine client, requesting the quarantine client to inspect conformance/non-conformance to the identified security policy. The quarantine client includes a receiver to receive the inspection request from the quarantine control apparatus, a storage unit storable inspection information to inspect conformance/non-conformance to the security policy, a reading unit to read out the inspection information from the storage unit, an inspection unit to inspect the quarantine client using the read-out inspection information, and an inspection result reporting unit to transmit an inspection result to the quarantine control apparatus. | 09-20-2012 |
20140059643 | WIRELESS COMMUNICATION APPARATUS, RECORDING MEDIUM, AND METHOD - A wireless communication apparatus includes an optical wireless receiving unit receiving a pseudo random number; an authentication code generator generating an authentication code based on the pseudo random number received by the optical wireless receiving unit; and a wireless communication unit determining whether authentication using the authentication code with a given wireless communication apparatus is successful, and performing wireless communications with the given wireless communication apparatus when determining that the authentication using the authentication code with a given wireless communication apparatus is successful. | 02-27-2014 |
20150078362 | COMMUNICATION SYSTEM AND COMMUNICATION METHOD - In the present invention, a connection controller controls opening/closing of connection between a first communication unit that communicates with a terminal device and a second communication unit that communicates via a network. A connection setting unit instructs opening/closing of the connection to the connection controller in accordance with a user input received by an input unit in accordance with first identification information output from the terminal device displayed on a display unit. | 03-19-2015 |
20150181499 | COMMUNICATION APPARATUS, COMMUNICATION METHOD, AND COMMUNICATION SYSTEM - Disclosed is a communication apparatus capable of performing communications with another communication apparatus. The communication apparatus includes a plurality of communication interfaces using different communication paths, an information acquisition part configured to acquire information associated with the communication paths available to the communication apparatus and the other communication apparatus, a controller configured to select one of the communication interfaces for use in the communications with the other communication apparatus based on the information associated with the communication paths acquired from the information acquisition part, and a switcher configured to switch the communication interface used by the communication apparatus to the communication interface selected by the controller. | 06-25-2015 |
