However, an electronic seal stamp can be copied when the seal is software, and a dedicated reader hardware is often required when hardware such as a card is used as the seal. In any case, the electronic seal stamp focuses only on the function of authenticating, and it is an analog fun element that attaches to the seal and shape like a normal seal and selects the place to be stamped Was excluded. In addition, analog seals have the function of changing the meaning depending on the position to be stamped. Such operations are not performed on seals.

The present invention has been made to solve the above-described problem, and realizes an electronic seal stamp having analog fun and functional elements such as attaching a seal and a shape to a seal and selecting a place to be stamped like a normal seal stamp. The purpose is to do.

FIG. 2 is a block diagram illustrating a functional configuration of the authentication system according to the embodiment. 5 is a flowchart illustrating a flow of data exchange between devices in the authentication method of the embodiment. It is a figure showing the variation of the seal imprint when imprinting the electronic seal stamp of an embodiment. It is a figure which shows the seal surface of the electronic seal stamp of a modification.

  An embodiment of the electronic seal stamp of the present invention will be described. FIG. 1 is a schematic diagram illustrating an electronic seal stamp according to the embodiment.

The electronic seal stamp 1 is provided on the shaft portion 11, a tip portion of the shaft portion 11, a contact portion 12 capable of performing a touch operation on a touch panel display 21 of the terminal 2, and built in the shaft portion 11 and readable by a reader 23. And an RF tag unit 13. The shaft 11 has a round bar shape similar to the shaft of a normal seal. The contact portion 12 is provided at the tip of the shaft portion 11 and uses a conductive fiber, like a so-called stylus, and the user grips the shaft portion 11 and touches the touch panel display 21 of the terminal 2 with the contact portion 12. Operation can be performed at the time. The RF tag unit 13 is built in the shaft unit 11 and is a so-called RFID. The RFID may be an active type, but is described here as a passive type. It is desirable that the shape of the mark appear on the contact portion 12 because the shape becomes closer to a normal seal and the shape of the mark can be seen. That is, the electronic seal stamp is almost identical in appearance to a normal seal stamp.

The terminal 2 is a so-called PDA, and has a touch panel display 21 in which a display and an input unit are integrated. It also has a built-in communication unit 22 for communicating with the server 3. The communication means may be wifi, Bluetooth (registered trademark) or the like, and may be via the Internet. Further, the terminal 2 has the RFID reader 23 as a built-in or external device. On the touch panel display 21, documents as electronic data in a so-called PDF format or the like, and a contract in the example shown in the figure, are displayed.

As shown in FIG. 2, the server 3 includes a communication unit 31 and a memory 32 for storing a database, and communicates with the terminal 2. The database stores at least the ID of the RFID and the imprint data corresponding to the ID.

An authentication method using the electronic seal stamp 1 of the embodiment will be described.
The user simply carries out the operation of holding the electronic seal stamp 1 at an arbitrary position on the terminal 2 and stamping, and the following processing is performed.

First, when the electronic seal stamp 1 approaches the terminal 2, the terminal 2 detects the RF tag unit 1 by the RF tag reader 23, so that it is known that the electronic seal stamp 1 has approached the terminal 2 (step s 1).

Subsequently, the terminal 2 transmits the ID information of the RF tag unit 1 to the server 3 (Step s2).

In the server 3, the imprint information is allocated to the database stored in the memory 32. Specifically, among many IDs stored in the database, an ID corresponding to the ID information of the RF tag unit 1 is searched, and imprint data corresponding to the ID is assigned (step s3).

If the corresponding ID is found (step s4), the assigned imprint information is sent from the server 3 to the terminal 2 (step s5). If not found, an error signal is returned from the server 3 to the terminal 2, and an error message is displayed on the terminal 2 (step s6).

Subsequently, the contact portion 12 of the electronic seal stamp 1 contacts the touch panel display 21 (step s7). At this time, the terminal 2 detects the touched coordinates or DOM (step s8).

The terminal 2 displays the imprint based on the imprint information sent in step s5 on the detected coordinates or DOM on the document displayed on the touch panel display 21 (step s9).
At this time, the terminal 2 writes the date and time of the stamp on the document, and transmits the digital data and date / time data of the stamped document to the server 3 (step s10).

As described above, the user performs the stamping operation on the document on the screen of the terminal 2 using the electronic seal stamp 1 in the same manner as a normal seal, so that the image of the seal is displayed on the document on the screen. When the date is entered, the server 3 stores the digital data of the document and the date and time data, thereby generating a copy. In this way, the seal can be used in the same manner as a normal seal, so that the seal and the shape can be attached like a normal seal, and an electronic seal having an analog enjoyment element of selecting a place to be stamped can be realized. be able to.

It should be noted that the person who issues the electronic seal stamp 1 manages the server 3 and the database and issues software stored in the terminal 2 so that the uniqueness of the electronic seal stamp 1 and one-to-one correspondence with the user who is the owner of the electronic seal stamp 1 can be obtained. Can be guaranteed, and the user can be credited.

  As a modified example of the present invention, a stylus used like a pen, instead of a seal, can have a similar function. That is, according to the stylus provided with the shaft portion, a contact portion provided at the tip of the shaft portion and capable of performing a touch operation on the touch panel display, and an RF tag portion built in the shaft portion and readable by a reader, When writing or drawing on the PDA with this stylus, it is possible to recognize who the stylus is and record it for each trajectory. Therefore, for example, even with a signature using a stylus, an individual can be identified from both the handwriting of the signature and the ID information linked to this locus. The ID information associated with the locus may be confirmed later by an operation such as displaying the locus by clicking the locus. In addition, if attributes are registered for each stylus by switching RFID or switching for each pen, for example, the color of the trace on the screen changes and it can be used like a colored pencil, and each stylus has a different meaning It can also be done.

  Further, in the conventional seal, even if the seal is the same, the seal imprint changes depending on the type of paper, the type of vermilion, and the pressing strength. By expressing this with an electronic seal stamp, it is possible to increase the elements of analog enjoyment of the seal stamp. As shown in FIG. 4, in the related art, the density of the seal is different depending on the strength of pressing the seal, but the electronic seal is also detected by detecting the length of pressing time and, if possible, the strength. It can be reflected in the shade of the seal. Specifically, between the above-described steps s8 and s9, a step of detecting the length and strength of the stamping time, that is, the time during which the electronic seal stamp is in contact with the touch panel display, and a step of detecting the density corresponding to the step. It is sufficient if there is a step of creating or selecting a seal imprint on the server side or the terminal side.

Further, at the time of stamping, the type of paper and the type of vermilion may be selectable. Also in this case, as shown in FIG. 4, the shading, texture, and color of the seal are changed, thereby increasing the analog enjoyment of the seal. Specifically, before step s9, there may be a step of allowing the user to select the type of paper or vermilion, and a step of creating or selecting an imprint of the texture and color corresponding to the step on the server side. Moreover, it is also possible to operate so that the type of paper or vermilion can be selected afterwards. Such operations not only increase the elements of enjoyment, but also leave unique shadows for each, leading to further prevention of fraud.

  The seal portion may be a conductive portion at two points, that is, a plurality of contact portions 12 provided on the same plane. In this case, the distance relationship between the two points is invariable. Therefore, the software in the terminal 2 is set to recognize that the two-point touch having the specific distance relationship is a seal, so that the touch panel display 21 side can be recognized. Thus, it is possible to distinguish between a touch on the stylus pen portion or a touch with two fingers and a touch on the seal portion. In addition, the presence of the plurality of conductive contact portions makes it possible to express the seal as bent, that is, tilted about an axis.

The seal can be bent even if the number of conductive contacts is two. However, if there are three or more conductive contacts, the plurality of contacts are regular polygonal. Except for the case, since the direction of the seal can be completely specified by the distance and the positional relationship of the three points, it is possible to express that the direction of the seal is upside down. In addition, it is possible to express that the shading of the seal differs depending on the position due to the shift of the contact timing or the shift of the strength of the plurality of conductive contact portions. When the plurality of contact portions have a regular polygonal shape, it can be interpreted that the uppermost contact portion on the document is above the seal. In such a case, the seal is not turned upside down, that is, if there are two contact portions, the seal can be bent and pushed within a range of 180 degrees, and the contact portion has an equilateral triangle. With three points constituting the vertex, the seal can be bent and pressed within a range of 120 degrees.

  For example, FIG. 5 shows the stamping surface 14 of the electronic seal stamp 10 having three or more conductive contact portions 15. The electronic seal stamp 10 is the same as the electronic seal stamp 1 in that the electronic seal stamp 10 includes a shaft 11 and an RF tag unit 13 built in the shaft 11 and readable by a reader 23. The difference is that three contact portions 15 capable of touching the two touch panel displays 21 are provided in the same plane. The three contact portions 15 are the same conductor as the contact portions 12, but the other portions of the stamping surface 14 are non-conductive. Therefore, when the stamping surface 14 contacts the touch panel display 21, the three contact portions 15 contact the touch panel display 21 and it is recognized that three points have been touched. The three contact portions 15 are in the positional relationship of the vertices of the isosceles triangle, and the positional relationship is unchanged. Therefore, in the software installed on the terminal 2, by setting so that the three-point touches in this positional relationship are recognized as an electronic seal stamp, it is possible to distinguish the touch from the stylus or the finger or the three-point touch. Can be. Further, since the positional relationship between the three contact portions 15 is not the vertex of an equilateral triangle, the direction of the electronic seal stamp, that is, the inclination in the rotation direction about the axis 11 can be detected, so that the seal stamp is bent and pressed. Will be possible.

  The contact portion 16 is a contact portion that appears and disappears. The contact portion 16 physically appears on the stamping surface 14 or retracts into the shaft 11 like a conventional ballpoint pen having a plurality of colors. More specifically, a wick 161 loaded in the shaft 11 and having a contact portion 16 at one end slides in the axial direction within the shaft 11, and an operating portion 162 provided at the other end of the wick 161 is attached to the shaft 11. The contact portion 16 can appear and disappear on the stamping surface 14 by operating the operation portion 162.

When the contact portions 16 are retracted in the shaft 11, only the three contact portions 15 appear on the stamping surface 14, so that the electronic seal stamp 10 can be stamped as described above. When the contact portion 16 appears on the stamping surface 14, in the software installed in the terminal 2, the four touches having this positional relationship are recognized as another form of the electronic seal stamp. Even in the case of the RFID 13, by registering a plurality of imprints associated with this ID in the server 3, it is possible to press a different type of imprint. In addition, a plurality of contacting portions 16 that can appear and disappear can be provided, and if they are designed so that they can appear alternately or in a state where none of them appear, like a normal ballpoint pen having a plurality of colors, three contacting portions 16 can be provided. A plurality of different forms can be recognized based on the positional relationship between the contact portion 15 and the appearing contact portion 16. Specifically, a square mark, a circle mark, or the like can be registered in association with one ID, or can be registered so as to be the same seal with a different color of vermilion.
It should be noted that if a character with a seal imprint appearing on the stamp face 14 appears as a conventional seal, it is desirable in design, but illustration is omitted.

In addition, some conventional seals have a seal on the opposite side of the pen. Similarly, a part opposite to the pen tip of a normal stylus pen may be a seal. In this case, the terminal detects the RFID regardless of which one is used, so it is necessary for the software to determine whether the contact is with the stylus part or the seal part. By providing a plurality of conductive portions in the plane, the stylus portion and the seal portion can be distinguished.

Note that the technical scope of the present invention is not limited to the above embodiments, and may be determined according to the state of the equipment that can be prepared, for example, using Bluetooth (registered trademark), Bluetooth (registered trademark) Low Energy, or acoustic Beacon instead of RFID. The components may be changed and increased or decreased.
