  Next, the operation of the image forming system in this embodiment will be described.

  FIG. 2 is a diagram schematically showing a state in which the user UR1 is present near the image forming apparatus 100.

  Referring to FIG. 2, user UR1 wears wearable terminal 200a. When the user UR1 wears the wearable terminal 200a, the wearable terminal 200a performs biometric authentication of the user UR1 by comparing the pulse wave pattern of the user UR1 with the pulse wave pattern stored in the auxiliary storage device 204. . When the wearable terminal 200a succeeds in biometric authentication of the user UR1, the wearable terminal 200a transmits a beacon (signal) at regular intervals using the wireless communication unit 205.

  When the wearable terminal 200a approaches within the range in which the image forming apparatus 100 can communicate, the image forming apparatus 100 receives the beacon from the wearable terminal 200a. Further, the image forming apparatus 100 constantly transmits a beacon, and the wearable terminal 200 a receives the beacon from the image forming apparatus 100. As a result, the image forming apparatus 100 and the wearable terminal 200a recognize each other.

  When the wearable terminal 200a recognizes the presence of the image forming apparatus 100, the wearable terminal 200a transmits an authentication key for the user UR1 to the image forming apparatus 100. The image forming apparatus 100 authenticates the user UR1 based on the received authentication key. Hereinafter, the authentication using this authentication key may be referred to as “first authentication”. The first authentication is performed by the authentication processing unit 107.

  When the image forming apparatus 100 recognizes the presence of the wearable terminal 200a, the image forming apparatus 100 transmits an authentication key regarding the image forming apparatus 100 to the wearable terminal 200a. The wearable terminal 200a authenticates the image forming apparatus 100 based on the received authentication key.

  FIG. 3 is a diagram schematically showing a user table when the first authentication of the user UR1 is successful.

  Referring to FIG. 3, the user table is a table showing user names of users who can use image forming apparatus 100, an authentication key, and whether or not the first authentication is successful. The image forming apparatus 100 performs the first authentication for the user wearing the wearable terminal 200 by collating the authentication key received from the wearable terminal 200 with the authentication key described in the user table.

  When the first authentication succeeds, the image forming apparatus 100 updates the first authentication column of the user table for that user to “OK”. Thereby, the wearable terminal 200 (the user who has succeeded in the first authentication) existing within the communicable range of the image forming apparatus 100 is grasped. When the communication with the wearable terminal 200 of the user who succeeds in the first authentication is interrupted, the image forming apparatus 100 updates the first authentication column of the user table of the user to “NO”. The case where the communication between the image forming apparatus 100 and the wearable terminal 200 is interrupted means, for example, when the wearable terminal 200 moves outside the range in which the image forming apparatus 100 can communicate, or when the user removes the wearable terminal 200. Is.

  When only the user UR1 has succeeded in the first authentication, only the user UR1 is written as “OK” in the first authentication column of the user table, and the other users succeed in the first authentication. Since it has not been performed (it does not exist in the vicinity of the image forming apparatus 100), it is described as “NO”.

  FIG. 4 is a flowchart showing the first authentication executed by the image forming apparatus 100 according to the first embodiment of the present invention.

  Referring to FIG. 4, CPU 101 of image forming apparatus 100 determines whether a beacon is received from wearable terminal 200 (S101). The CPU 101 repeats the process of step S101 until it determines that a beacon has been received.

  When it is determined in step S101 that the beacon has been received (YES in S101), the CPU 101 exchanges the authentication key with the wearable terminal 200 (S103), and the authentication key received from the wearable terminal 200 is stored in the user table. It is determined whether or not it matches the described authentication key (S105).

  When it is determined in step S105 that the authentication key received from the wearable terminal 200 matches the authentication key described in the user table (YES in S105), the CPU 101 determines whether the user wearing the wearable terminal 200 is the first Authentication is performed (S107), and the process proceeds to step S101.

  When determining in step S105 that the authentication key received from the wearable terminal 200 does not match the authentication key described in the user table (NO in S105), the CPU 101 determines that the first authentication has failed ( S109), without performing the first authentication for the user wearing the wearable terminal 200, the process proceeds to step S101.

  FIG. 5 is a diagram schematically showing a state in which there are a plurality of users who have succeeded in the first authentication.

  Referring to FIG. 5, users UR1, UR2, and UR3 exist near image forming apparatus 100. Each of users UR1, UR2, and UR3 wears wearable terminal 200a, 200b, and 200c. Each of wearable terminals 200a, 200b, and 200c has succeeded in biometric authentication of each of users UR1, UR2, and UR3. Each of the wearable terminals 200a, 200b, and 200c is a wristband type that is wrapped around an arm here.

  When the wearable terminal 200a, 200b, or 200c approaches the range in which the image forming apparatus 100 can communicate, the image forming apparatus 100 exchanges the authentication key with the wearable terminal 200a, 200b, or 200c. As a result, the image forming apparatus 100 succeeds in the first authentication of each of the users UR1, UR2, and UR3, and opens the first authentication column of the user table (FIG. 3) for the user UR1, UR2, or UR3. Update to "OK". In FIG. 5, the image forming apparatus 100 has succeeded in the first authentication of each of the plurality of users UR1, UR2, and UR3. Each of the wearable terminals 200a, 200b, and 200c has succeeded in authenticating the image forming apparatus 100.

  As shown in FIG. 2, when the number of users who have succeeded in the first authentication is one, the image forming apparatus 100 can determine that the user UR1 is the subject of the operation received through the operation panel 106. However, as shown in FIG. 5, when there are a plurality of users who have succeeded in the first authentication, the image forming apparatus 100 cannot determine who is the subject of the operation received through the operation panel 106.

  The image forming apparatus 100 authenticates the user who operates the operation panel 106 based on the characteristics of the hand or arm of the user who operates the operation panel 106. Hereinafter, the authentication of the user who operates the operation panel 106 may be referred to as “second authentication”. The second authentication is performed by the authentication processing unit 107.

  In the present embodiment, the image forming apparatus 100 performs the second authentication by the following method.

  When the image forming apparatus 100 is operated through the operation panel 106, the image forming apparatus 100 uses the wireless communication unit 105 to notify the start of the second authentication (hereinafter sometimes referred to as a second authentication start signal). ) Is transmitted to each of the wearable terminals 200a, 200b, and 200c. Each of the wearable terminals 200a, 200b, and 200c is the wearable terminal 200 of the user who has succeeded in the first authentication, and is the wearable terminal 200 existing within the communicable range of the image forming apparatus 100.

  Further, the image forming apparatus 100 vibrates the operation panel 106 in a required vibration pattern when an operation is performed through the operation panel 106.

  When the wearable terminals 200a, 200b, and 200c each receive the signal notifying the start of the second authentication, the wearable terminals 200a, 200b, and 200c start detecting the vibration pattern of the user's hand or arm using the acceleration sensor 208. When the wearable terminals 200a, 200b, and 200c complete the detection of the vibration patterns, the wireless communication unit 205 is used to transmit information indicating the detected vibration patterns to the image forming apparatus 100. When the wearable terminal 200 cannot detect the vibration pattern for a certain period of time, the wearable terminal 200 may transmit information indicating that the vibration pattern is not detected.

  The image forming apparatus 100 uses the wireless communication unit 105 to receive information indicating the vibration pattern from the wearable terminals 200a, 200b, and 200c. The image forming apparatus 100 controls the image forming apparatus 100 based on the identity of the vibration pattern when the operation panel 106 is vibrated and the vibration pattern indicated by the information received from each of the wearable terminals 200a, 200b, and 200c. The user who operates (here, user UR1) is authenticated (specified).

  The image forming apparatus 100 performs the second authentication when the operation is performed through the operation panel 106, and repeatedly performs the second authentication at a required time interval after the operation is performed through the operation panel 106. May be.

  Further, the image forming apparatus performs the second authentication when the operation for instructing the execution of the print job is performed through the operation panel 106, instead of performing the second authentication when the operation is performed through the operation panel 106. May be. In this case, the image forming apparatus 100 executes the print job using the image forming unit 109 after the second authentication of the user who operates the operation panel 106 is successful.

  FIG. 6 is a graph schematically showing each of the vibration pattern when the operation panel 106 is vibrated and the vibration pattern indicated by the information received from the wearable terminal 200 in the first embodiment of the present invention. . FIG. 6A is a graph of a vibration pattern when the operation panel 106 is vibrated. FIG. 6B is a graph of a vibration pattern indicated by information received from one wearable terminal 200. FIG. 6C is a graph of a vibration pattern indicated by information received from another wearable terminal 200.

  Referring to FIG. 6 (a), operation panel 106 is vibrated at time tm1 for a period of time Δt1 (s) at frequency FQ1, for example, and then stopped for a period of time Δt2. After that, the operation panel 106 is repeatedly vibrated for a time of Δt1 (s) and stopped for a time of Δt2.

  Referring to FIG. 6B, vibration of operation panel 106 is transmitted to wearable terminal 200 worn by a user who operates operation panel 106, via the hand and arm of the user who operates operation panel 106. As a result, in the wearable terminal 200 worn by the user who operates the operation panel 106, the wearable terminal 200 vibrates at the frequency FQ1 for a period of Δt1 (s) at a time tm2 slightly after the time tm1 and then stands still for a period of Δt2. Such a vibration pattern is detected. After that, the wearable terminal 200 worn by the user who operates the operation panel detects a vibration pattern in which the vibration for the time Δt1 (s) and the standstill for the time Δt2 are repeated.

  When the information indicating the vibration pattern illustrated in FIG. 6B is received, the image forming apparatus 100 determines that the vibration pattern indicated by the received information matches the vibration pattern when the operation panel 106 is vibrated. The image forming apparatus 100 authenticates the user of the wearable terminal 200, which is the transmission source of the received information, as a user who operates the image forming apparatus 100.

  Referring to FIG. 6C, in wearable terminal 200 worn by a user who is not operating the operation panel, a vibration pattern unrelated to the vibration pattern shown in FIG. 6A is detected. This vibration pattern is caused by an operation of the user of the wearable terminal 200, which is the information transmission source, which is unrelated to the operation of the operation panel 106.

  When the information indicating the vibration pattern illustrated in FIG. 6C is received, the image forming apparatus 100 determines that the vibration pattern indicated by the received information does not match the vibration pattern when the operation panel 106 is vibrated. The image forming apparatus 100 does not authenticate the user of the wearable terminal 200, which is the transmission source of the received information, as a user who operates the image forming apparatus 100.

  Regarding the identity of the vibration pattern when the operation panel 106 is vibrated and the vibration pattern indicated by the information received from the wearable terminal 200, the vibration detection capability of the wearable terminal 200 is considered, and a certain degree of error is allowed. Is preferably determined as follows.

  Further, the vibration pattern when vibrating the operation panel 106 may be randomly changed every time. When another image forming apparatus exists within the communication range of the image forming apparatus 100, each image forming apparatus may vibrate the operation panel in different vibration patterns.

  Further, when the vibration pattern indicated by the information received from any of the wearable terminals 200 does not match the vibration pattern when the operation panel 106 is vibrated, or there is no wearable terminal 200 that succeeds in the first authentication. When the operation is received through the operation panel 106, the image forming apparatus 100 may determine that the operation is received from the user who does not wear the wearable terminal 200, and may determine that the authentication has failed. In this case, the image forming apparatus 100 may request a normal ID (Identification) and password input, or may request biometric authentication by the main body of the image forming apparatus 100. Further, the image forming apparatus may accept only the operation related to the function that the unauthorized user is permitted to use, or may prohibit the use. The operation of the image forming apparatus 100 in this case may be determined by the management policy of the image forming apparatus 100.

  FIG. 7 is a flowchart showing the second authentication executed by the image forming apparatus 100 in the first embodiment of the present invention.

  Referring to FIG. 7, CPU 101 of image forming apparatus 100 determines whether an operation on operation panel 106 has been accepted (S151). The CPU 101 repeats the process of step S151 until it determines that the operation on the operation panel 106 has been accepted.

  When it is determined in step S151 that the operation of the operation panel 106 has been accepted (YES in S151), the CPU 101 determines whether or not there is a user (wearable terminal 200) who has succeeded in the first authentication (S153). ).

  When it is determined in step S153 that there are users who have succeeded in the first authentication (YES in S153), the CPU 101 causes the wearable terminals 200 of all the users who have succeeded in the first authentication to display the second An authentication start signal is transmitted (S155). Subsequently, the CPU 101 vibrates the operation panel 106 (S157) and determines whether or not the information indicating the vibration pattern is received from the wearable terminal 200 (S159). The CPU 101 repeats the process of step S159 until it determines that the information indicating the vibration pattern is received from the wearable terminal 200.

  When it is determined in step S159 that the information indicating the vibration pattern is received from the wearable terminal 200 (YES in S159), the CPU 101 determines whether the vibration pattern indicated by the received information matches the vibration pattern of the operation panel 106. Is determined (S161).

  When it is determined in step S161 that the vibration pattern indicated by the received information matches the vibration pattern of the operation panel 106 (YES in S161), the CPU 101 of the wearable terminal 200 that is the transmission source of the information indicating the matched vibration pattern. Second authentication is performed on the user (S163). Next, the CPU 101 determines whether or not a fixed time has elapsed since the operation of the operation panel 106 was accepted (S165). The CPU 101 repeats the process of step S165 until it is determined that a certain time has elapsed since the operation of the operation panel 106 was accepted.

  When it is determined in step S165 that the certain time has elapsed since the operation of the operation panel 106 was accepted (YES in S165), the CPU 101 proceeds to the process of step S153.

  When it is determined in step S161 that the vibration pattern indicated by the received information does not match the vibration pattern of the operation panel 106 (NO in S161), the CPU 101 has received the information indicating the vibration pattern from all wearable terminals 200. It is determined whether or not (S167).

  When it is determined in step S167 that the information indicating the vibration pattern has not been received from all wearable terminals 200 (NO in S167), the CPU 101 proceeds to the process of step S159.

  When it is determined in step S153 that there is no user who has succeeded in the first authentication (NO in step S153), or when it is determined in step S167 that information indicating a vibration pattern has been received from all wearable terminals 200. (YES in S167), the CPU 101 determines that the operation has been accepted from the user who does not wear the wearable terminal 200, and determines that the authentication has failed (S169). In this case, the CPU 101 proceeds to the process of step S151 without performing the second authentication.

  FIG. 8 is a flowchart showing the operation of wearable terminal 200 in the first exemplary embodiment of the present invention.

  Referring to FIG. 8, CPU 201 of wearable terminal 200, when worn by the user, performs biometric authentication of the user (S401) and starts beacon transmission (S403). Next, the CPU 201 determines whether or not a beacon has been received from the image forming apparatus 100 (S405). The CPU 201 repeats the processing of steps S403 and S405 until it determines that a beacon has been received from the image forming apparatus 100.

  When it is determined in step S405 that the beacon is received from the image forming apparatus 100 (YES in S405), the CPU 201 authenticates the image forming apparatus 100 by exchanging the authentication key with the image forming apparatus 100 ( S407). Subsequently, the CPU 201 determines whether or not the second authentication start signal is received from the image forming apparatus 100 (S409).

  If it is determined in step S409 that the second authentication start signal is not received from the image forming apparatus 100 (NO in S409), the CPU 201 proceeds to the process of step S415.

  When it is determined in step S409 that the second authentication start signal has been received from the image forming apparatus 100 (YES in S409), the CPU 201 detects vibration of the wearable terminal 200 (S411) and the detected information is formed into an image. It is transmitted to the device 100 (S413), and the process proceeds to step S415.

  In step S415, the CPU 201 determines whether the communication with the image forming apparatus 100 is completed (S415).

  When it is determined in step S415 that the communication with the image forming apparatus 100 is not completed (NO in S415), the CPU 201 proceeds to the process of step S409.

  When it is determined in step S415 that the communication with the image forming apparatus 100 is not completed (YES in S415), the CPU 201 ends the process.

  [Second Embodiment]

  The second and third embodiments perform second authentication by a method different from that of the first embodiment. Referring to FIG. 5, in the present embodiment, image forming apparatus 100 performs the second authentication by the following method.

  When an operation is performed through the operation panel 106, the image forming apparatus 100 uses the wireless communication unit 105 to output the second authentication start signal to the wearable terminals 200a, 200b, and 200c (when the first authentication succeeds). To each of the wearable terminals 200) of the users.

  The image forming apparatus 100 displays an arbitrary pattern on the operation panel 106 after transmitting the second authentication start signal. This pattern is intended to be traced to the user who operates the operation panel 106, and is preferably one-stroke readable.

  A user who operates the operation panel 106 traces the pattern displayed on the operation panel 106 with a finger or the like. When the wearable terminals 200a, 200b, and 200c receive the second authentication start signal, each of the wearable terminals 200a, 200b, and 200c starts detecting the movement of the hand or arm of the user wearing the wearable terminal 200, using the acceleration sensor 208. When each of the wearable terminals 200a, 200b, and 200c completes the detection of the movement of the user's hand or arm, the wearable terminals 200a, 200b, and 200c use the wireless communication unit 205 to transmit information indicating the detected movement to the image forming apparatus 100. If the wearable terminal 200 cannot detect the movement of the user's hand or arm for a certain period of time, the wearable terminal 200 may transmit information indicating that the movement of the user's hand or arm is not detected.

  The image forming apparatus 100 uses the wireless communication unit 105 to receive, from the wearable terminals 200a, 200b, and 200c, information indicating the movement of the hand or arm of the user wearing the wearable terminal 200. The image forming apparatus 100 is a user who operates the image forming apparatus 100 based on the identity of the pattern displayed on the operation panel 106 and the locus of movement indicated by the information received from each of the wearable terminals 200a, 200b, and 200c. Authenticate (specify).

  FIG. 9 is a graph schematically showing each of a screen displayed on operation panel 106 and a movement trajectory indicated by information received from wearable terminal 200 in the second exemplary embodiment of the present invention. FIG. 9A is a screen displayed on the operation panel 106. FIG. 9B is a diagram showing a locus of movement indicated by information received from one wearable terminal 200. FIG. 9C is a diagram showing a locus of movement indicated by information received from another wearable terminal 200.

  Referring to FIG. 9A, a screen including a pattern CD and a message requesting tracing the pattern CD is displayed on operation panel 106.

  With reference to FIG. 9B, movements of the user's hand and arm when tracing the pattern CD are transmitted to the wearable terminal 200 worn by the user who operates the operation panel 106. As a result, in the wearable terminal 200 worn by the user who operates the operation panel 106, a motion having a locus similar to the pattern CD is detected.

  When the movement information shown in FIG. 9B is received, the image forming apparatus 100 determines that the movement locus indicated by the received information matches the pattern CD displayed on the operation panel 106. The image forming apparatus 100 authenticates the user of the wearable terminal 200, which is the transmission source of the received information, as a user who operates the image forming apparatus 100.

  With reference to FIG. 9C, the wearable terminal 200 worn by the user who is not operating the operation panel detects a movement that is a trajectory unrelated to the pattern CD. This movement is due to the operation of the user of the wearable terminal 200 that is the source of the information, which is unrelated to the operation of the operation panel 106.

  When the information indicating the movement illustrated in FIG. 9C is received, the image forming apparatus 100 determines that the trajectory of the movement indicated by the received information does not match the pattern CD displayed on the operation panel 106. The image forming apparatus 100 does not authenticate the user of the wearable terminal 200, which is the transmission source of the received information, as a user who operates the image forming apparatus 100.

  Regarding the identity of the pattern displayed on the operation panel 106 and the locus of movement indicated by the information received from the wearable terminal 200, the wearable terminal 200 should be allowed a certain degree of error in consideration of the movement detection ability. It is preferably judged.

  Further, the pattern displayed on the operation panel 106 may be randomly changed every time. When another image forming apparatus exists within the communication range of the image forming apparatus 100, each image forming apparatus may display different patterns. An arrow may be added to the pattern displayed on the operation panel 106 in order to restrict the direction in which the user who operates the operation panel 106 traces the pattern, or the pattern displayed on the operation panel 106 is determined in a writing order such as numbers. It may be a letter.

  Further, when the locus of movement indicated by the information received from any of the wearable terminals 200 does not match the pattern displayed on the operation panel 106, or the operation panel 106 does not have the wearable terminal 200 that has succeeded in the first authentication. If the operation is accepted through, the image forming apparatus 100 may determine that the operation has been accepted from the user who does not wear the wearable terminal 200, and may determine that the authentication has failed. In this case, the image forming apparatus 100 may request a normal ID and password input, or may request biometric authentication by the main body of the image forming apparatus 100. Further, the image forming apparatus may accept only the operation related to the function that the unauthorized user is permitted to use, or may prohibit the use. The operation of the image forming apparatus 100 in this case may be determined by the management policy of the image forming apparatus 100.

  Further, the image forming apparatus 100 displays a pattern on the operation panel 106 while in the sleep state or while returning from the sleep state to the normal operation state, and when the operation of tracing the pattern is started, The second authentication start signal may be transmitted to each of wearable terminals 200a, 200b, and 200c. In this case, the timing at which detection by the wearable terminal 200 starts is later than the timing at which the user starts tracing, so that the image forming apparatus 100 can detect the movement trajectory even when the movement trajectory matches a part of the pattern. The user of the wearable terminal 200, which is the source of the information, may be authenticated as a user who operates the image forming apparatus 100.

  Furthermore, the wearable terminal 200 always detects the movement of the user's hand or arm while it is within the communicable range with the image forming apparatus 100, and stores the information of the locus thereof. When the second authentication start signal is received from 100, the stored information may be transmitted to the image forming apparatus 100.

  FIG. 10 is a flowchart showing the second authentication executed by the image forming apparatus 100 according to the second embodiment of the present invention.

  Referring to FIG. 10, when CPU 101 of image forming apparatus 100 starts returning from the sleep state (S251), CPU 101 displays a screen including a pattern on operation panel 106 (S253). Subsequently, the CPU 101 performs the same processing as the processing after step S151 of the flowchart shown in FIG.

  After performing the same processing as the processing of step S155 of the flowchart shown in FIG. 7, the CPU 101 determines whether or not the information indicating the movement of the hand or the arm has been received from the wearable terminal 200 (S255). The CPU 101 repeats the process of step S255 until it determines that the information indicating the movement of the hand or the arm is received from the wearable terminal 200.

  When it is determined in step S255 that the information indicating the movement of the hand or arm is received from the wearable terminal 200 (YES in S255), the CPU 101 determines that the locus of the movement indicated by the received information is displayed on the operation panel 106. It is determined whether or not they match (S257).

  When it is determined in step S257 that the trajectory of the movement indicated by the received information matches the pattern displayed on the operation panel 106 (YES in S257), the CPU 101 transmits the information indicating the movement of the trajectory matching the pattern. Second authentication is performed for the user of the wearable terminal 200 (S259). Next, the CPU 101 performs the same processing as the processing from step S165 onward in the flowchart shown in FIG.

  When it is determined in step S257 that the trajectory of the movement indicated by the received information does not match the pattern displayed on the operation panel 106 (NO in S257), the CPU 101 indicates the movement of the hand or arm from all wearable terminals 200. It is determined whether information has been received (S261).

  When it is determined in step S261 that the information indicating the movement of the hand or arm has been received from all wearable terminals 200 (YES in S261), the CPU 101 determines that the operation has been accepted from the user who does not wear the wearable terminal 200. It is determined that the authentication has failed (S169). In this case, the CPU 101 proceeds to the process of step S151 without performing the second authentication.

  When it is determined in step S261 that the information indicating the movement of the hand or arm has not been received from all wearable terminals 200 (NO in S261), the CPU 101 proceeds to the process of step S255.

  The configuration of the image processing system according to the present embodiment and the operations other than those described above are the same as those in the first embodiment, and therefore the description thereof will not be repeated.

  [Third Embodiment]

  Referring to FIG. 5, in the present embodiment, image forming apparatus 100 performs the second authentication by the following method.

  As a premise, the image forming apparatus 100 has an operation panel 106 for operations other than operations related to operations for which authority is required for a user who has not succeeded in the second authentication (operations such as access to a box and an instruction to execute a print job). The operation of is permitted.

  The image forming apparatus 100 uses the touch panel (detection unit) of the operation panel 106 when an operation other than the login operation is performed through the operation panel 106, and the locus of the movement of the hand or arm of the user who operates the operation panel 106. To detect.

  Further, when an operation other than a login operation is performed through the operation panel 106, the image forming apparatus 100 uses the wireless communication unit 105 to output the second authentication start signal to the wearable terminals 200a, 200b, and 200c (first It is transmitted to each of the wearable terminals 200) of the users who have been successfully authenticated.

  When the wearable terminals 200a, 200b, and 200c receive the second authentication start signal, each of the wearable terminals 200a, 200b, and 200c starts detecting the movement of the hand or arm of the user wearing the wearable terminal 200, using the acceleration sensor 208. When each of the wearable terminals 200a, 200b, and 200c completes the detection of the movement of the user's hand or arm, the wearable terminals 200a, 200b, and 200c use the wireless communication unit 205 to transmit information indicating the detected movement to the image forming apparatus 100. If the wearable terminal 200 cannot detect the movement of the user's hand or arm for a certain period of time, the wearable terminal 200 may transmit information indicating that the movement of the user's hand or arm is not detected.

  The image forming apparatus 100 uses the wireless communication unit 105 to receive, from the wearable terminals 200a, 200b, and 200c, information indicating the movement of the hand or arm of the user wearing the wearable terminal 200. The image forming apparatus 100 is a user who operates the image forming apparatus 100 based on the identity of the locus detected by the operation panel 106 and the locus of movement indicated by the information received from each of the wearable terminals 200a, 200b, and 200c. Authenticate (specify).

  FIG. 11 is a graph schematically showing each of the locus detected by the operation panel 106 and the motion locus indicated by the information received from the wearable terminal 200, in the third exemplary embodiment of the present invention. FIG. 11A shows a screen displayed on the operation panel 106 and a locus detected by the operation panel 106. FIG. 11B is a diagram showing a locus of movement indicated by information received from one wearable terminal 200. FIG. 11C is a diagram showing a locus of movement indicated by information received from another wearable terminal 200.

  Referring to FIG. 11A, the operation panel 106 displays a job list and numeric keys. The user operating the operation panel 106 presses the numeric keys in the order of “7”, “9”, and “1”. In this case, the image forming apparatus 100 detects the locus indicated by the line LN1 as the locus of the movement of the hand or arm of the user who operates the operation panel 106 based on the order of pressing the keys.

  With reference to FIG. 11B, the wearable terminal 200 worn by the user who operates the operation panel 106 has a user's number when pressing the numeral keys in the order of “7”, “9”, and “1”. Hand and arm movements are transmitted. As a result, the wearable terminal 200 worn by the user who operates the operation panel 106 detects a movement having a locus similar to the line LN1.

  When the movement information shown in FIG. 11B is received, the image forming apparatus 100 determines that the movement trajectory indicated by the received information matches the trajectory detected by the operation panel 106. The image forming apparatus 100 authenticates the user of the wearable terminal 200, which is the transmission source of the received information, as a user who operates the image forming apparatus 100.

  Referring to FIG. 11C, in wearable terminal 200 worn by a user who is not operating the operation panel, a motion that is a locus unrelated to line LN1 is detected. This movement is due to the operation of the user of the wearable terminal 200 that is the source of the information, which is unrelated to the operation of the operation panel 106.

  When the information indicating the movement illustrated in FIG. 11C is received, the image forming apparatus 100 determines that the trajectory of the movement indicated by the received information does not match the trajectory detected by the operation panel 106. The image forming apparatus 100 does not authenticate the user of the wearable terminal 200, which is the transmission source of the received information, as a user who operates the image forming apparatus 100.

  Regarding the identity of the locus detected by the operation panel 106 and the locus of movement indicated by the information received from the wearable terminal 200, allow a certain degree of error in consideration of the movement detection ability of the wearable terminal 200. It is preferably judged.

  In addition, when the locus of movement indicated by the information received from any of the wearable terminals 200 does not match the locus detected by the operation panel 106, or the operation panel 106 is present even though there is no wearable terminal 200 that succeeded in the first authentication. If the operation is accepted through, the image forming apparatus 100 may determine that the operation is accepted from the user who does not wear the wearable terminal 200, and may determine that the authentication has failed. In this case, the image forming apparatus 100 may request a normal ID and password input, or may request biometric authentication by the main body of the image forming apparatus 100. Further, the image forming apparatus may accept only the operation related to the function that the unauthorized user is permitted to use, or may prohibit the use. The operation of the image forming apparatus 100 in this case may be determined by the management policy of the image forming apparatus 100.

  Furthermore, the wearable terminal 200 always detects the movement of the user's hand or arm while it is within the communicable range with the image forming apparatus 100, and stores the information of the locus thereof. When the second authentication start signal is received from 100, the stored information may be transmitted to the image forming apparatus 100.

  FIG. 12 is a flowchart showing the second authentication executed by the image forming apparatus 100 according to the third embodiment of the present invention.

  Referring to FIG. 12, CPU 101 of image forming apparatus 100 determines whether or not an operation on operation panel 106 has been accepted (S151). The CPU 101 repeats the process of step S151 until it determines that the operation on the operation panel 106 has been accepted.

  When it is determined in step S151 that the operation of the operation panel 106 has been received (YES in S151), the CPU 101 detects the trajectory of the movement of the hand or arm of the user who operates the operation panel 106 (S351). Subsequently, the CPU 101 performs the same processing as the processing after step S153 in the flowchart shown in FIG.

  After performing the same processing as the processing of step S155 of the flowchart shown in FIG. 7, the CPU 101 determines whether or not the information indicating the movement of the hand or the arm has been received from the wearable terminal 200 (S353). The CPU 101 repeats the process of step S353 until it determines that the information indicating the movement of the hand or arm is received from the wearable terminal 200.

  When it is determined in step S353 that the information indicating the movement of the hand or arm has been received from the wearable terminal 200 (YES in S353), the CPU 101 determines that the movement trajectory indicated by the received information is the trajectory detected by the operation panel 106. It is determined whether or not they match (S355).

  When it is determined in step S355 that the trajectory of the movement indicated by the received information matches the trajectory detected by the operation panel 106 (YES in S355), the CPU 101 wears the wearable information of the sender of the information indicating the movement of the matched trajectory. Second authentication is performed on the user of the terminal 200 (S357). Next, the CPU 101 performs the same processing as the processing from step S165 onward in the flowchart shown in FIG.

  When it is determined in step S355 that the trajectory of the movement indicated by the received information does not match the trajectory detected by the operation panel 106 (NO in S355), the CPU 101 indicates the movement of the hand or arm from all wearable terminals 200. It is determined whether information has been received (S359).

  When it is determined in step S359 that the information indicating the movement of the hand or arm has been received from all wearable terminals 200 (YES in S359), the CPU 101 determines that the operation has been received from the user who does not wear the wearable terminal 200. It is determined that the authentication has failed (S169). In this case, the CPU 101 proceeds to the process of step S151 without performing the second authentication.

  When it is determined in step S359 that the information indicating the movement of the hand or arm has not been received from all wearable terminals 200 (NO in S359), the CPU 101 proceeds to the process of step S353.

  The configuration of the image processing system according to the present embodiment and the operations other than those described above are the same as those in the first embodiment, and therefore the description thereof will not be repeated.
