Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a livestock management system, and more particularly to a livestock management system for registering and collating nose print data of livestock and authenticating the owner of the livestock.

[0002]

2. Description of the Related Art It is well known that a nose print of a domestic animal is peculiar to an individual, so that a nose print of a cow or the like is collected and used for identification of an individual such as a cow having the same appearance. . For example, Japanese Patent Application Laid-Open No. 9-265523 discloses that a nose print of a cow or dog is photographed by a press image pickup unit incorporating a camera and an illumination light source, and the photograph is taken as a nose print image digitized by an image input board of a personal computer. An example is shown in which the image is captured by a computer, corrected for the position and rotation of an image, and then recorded on a disk device or the like.

[0003] Also, since the nose prints of livestock can be used for individual identification of livestock, a nose print image is attached to the ownership information of the cattle, registered with the stock raising association, etc., and lost or stolen during grazing. In such a case, a nose print of the cow is collected and collated with registered information to determine an owner.

FIG. 7 is a diagram for explaining the conventional livestock management method. In FIG. 7, the nose print of the domestic animal 42 is read by the nose print sensor 41 and a nose print image hard copy 43 is created. Owner information (owner name, address, occupation), individual livestock information (species, date of birth, pedigree, position of mottle,
Appearance features such as shape and color, birth information or purchase information)
And submit the nose print image hard copy 43 to the livestock association. The livestock cooperative checks the registrants and the contents. In other words, if the registrant is the owner himself, it is confirmed that the picture, written name, address, etc. of the presented ID card match the face of the person, the name, address of the owner information. or,
Check with the stockbreeding association member's card or resident's card whether there is any unnatural point, such as whether the address on the registration form actually exists in the area, or whether the person is an occupation that owns livestock. If there is no problem, a management number (serial number or the like) is added, the file is stored in the registration ledger 45, and a copy is given to the registrant.

[0005] When a registrant wants to obtain authentication, he or she asks the livestock cooperative to collect the nose print of the livestock and presents the registration certificate. The stock raising association checks the collected nose pattern image, the characteristics of the livestock with the nose print image of the registration number in the registration ledger, and the livestock individual information, and if they match, the owner of the management number authenticates the owner of the livestock.

[0006] Although the publications indicate that a nose print image of a livestock is taken into a computer and recorded, the nose print data of the livestock is collected, registered together with livestock individual information and owner information, and presented again. There is no disclosure of a computer system in which the entire process of authenticating the owner with the nose print data and attached information is automated as much as possible.

[0007]

Therefore, the conventional livestock management method has the following problems. That is, since the confirmation of the registration information, the preparation of the authentication data for collation, and the collation work in some cases are performed manually, the work load of the person in charge of the registration and authentication processing is large.

The second purpose is that a computer system for livestock nose print registration and authentication processing would be convenient if the nose print collection and authentication processing could be carried out in a livestock barn, a farm or in the vicinity thereof instead of bringing livestock such as cows to a fixed place. It was considered that the registration procedure and processing must be performed by a qualified person in the presence of a witness, and it is more preferable that the registration procedure and processing be performed at the office of a predetermined organization where the data for confirmation is easily accessible. The purpose is to provide a highly convenient system. That is, a portable authentication device having a nose print collecting function and a registration device are connected to each other by communication to constitute a system.

A third object is to provide an authentication device which realizes high security and a simple device structure. That is,
Since the individual information of livestock is stored in the authentication device, it is possible to disguise by analyzing the device, program, and data. However, this is not possible. In order to efficiently perform the authentication, the apparatus configuration is simplified and the cost is reduced so that the cost is not increased when a plurality of authentication apparatuses are used.

It is. These components are connected by a bus 5.

Next, the operation of the official registration authentication apparatus will be described with reference to the drawings. FIG. 2 shows the registration operation. First, the person in charge of registration selects the noseprint registration icon-attached data registration on the screen of the display unit 8, and according to the instructions on the screen, the owner information (owner name, address, sex, Date of birth, occupation), individual livestock information (species, sex, date of birth, pedigree,
The appearance features such as the position, shape, and color of the mottle, birth information or purchase information) are key-in or OC input from the data input unit 9.
Enter R.

Next, the collation check of the owner information with the livestock union member database or the inhabitants database of the municipal office is automatically performed. That is, when the stock raising member number is entered on the OCR sheet, the user accesses the device having the stock raising member database through the communication adapter 6 using the member number as a key, and the name, address, gender, date of birth, and occupation. The information is obtained and checked against the previously read owner information. If there is no entry of the livestock union member number, access is made to the management device of the resident database of the municipal office corresponding to the address of the owner information. For example, for each municipality in the registered jurisdiction,
A subprogram (function) describing a procedure for extracting and transmitting the IP address, password, and index key information for access from the owner information is automatically started to receive the owner's resident data. The received data and the owner information are collated.

Next, the validity with the occupation is automatically checked for each type of livestock whose ownership is declared. For example, even if you have declared that you own a beef cattle or dairy cattle, you will not be accepted if your occupation is marked other than livestock and livestock brokerage. In the case of the livestock brokerage business, the purchase information is checked, and an instruction to confirm and request the presentation of the certificate is output on the screen. In addition, if it is described as self-childbirth, it is automatically checked whether the livestock on the female side of the parent is registered in the present system. If necessary, another livestock management system is accessed through the communication adapter 6.

If there is no doubt in these checks, the reception control number (k) is given together with the owner information and the livestock individual information. If the owner information is new, a record is added to the owner file. The livestock individual information is stored in a unique livestock data file. At the same time, the date, time (hours, minutes, and seconds) are read from the clock 7 and are read as time stamp 1 (TS
1), the owner file record number (m), livestock data file name (n), and TS1 are added as records corresponding to the management number of the index file, and the entire file is encrypted with the encryption key of the key data 4-4. And store it.

The registration applicant who has been notified of the management number and TS1 requests a noseprint collection of the target livestock immediately or on a different day. The person in charge of collecting a nose print selects a nose print registration icon-registered nose print collection on the screen of the display unit 8. After inputting the decryption key, enter the management number of the applicant declaration and TS1 according to the screen instructions. The index file is decrypted, the record corresponding to the management number is accessed, the recorded TS1 and the input TS1 are confirmed to match, and it is confirmed that the collection applicant is not spoofing.

Next, a livestock individual information confirmation instruction and provisionally registered livestock individual information (appearance features such as species, male and female, date of birth, pedigree, position of spots, shape, color, etc.) are displayed. The registration receptionist checks whether the target livestock and the contents of the individual information on the screen match, and corrects any differences in the position, shape, color, etc. of the mottled pattern.

When these are confirmed, the sensor unit of the nose print sensor 1 is applied to the nose of the livestock according to the screen instructions. Then, the image signal from the sensor unit is A / D converted and converted into a main memory 3.
A nose print image is created in a predetermined area, and this image is further normalized. First, a horizontal axis line is obtained from the contour line of the image. If the horizontal axis line is slightly inclined, a rotation process is performed so as to be horizontal. An image center point is obtained for the rotated image using the left-right symmetry of the image. The leftmost point and the rightmost point on the contour are reduced at the same rate in the X and Y directions so that the larger one from the center point has a predetermined size in the X direction. If the size exceeds a predetermined size in the Y direction, the image is reduced again at the same rate in the X and Y directions until it fits.

Next, for example, a number of changing points on the nose print line are picked up, and the X, Y coordinates and distribution (relative positional relationship between the changing points) from the center point are extracted to extract characteristic data. You. Further, the date and time are read from the clock 7, and this is set as a time stamp 2 (TS2). The above feature data, normalized image data, reduction ratio, and TS2 are used as nose print data. A livestock data file n is determined from the indexed record of the index file, the type and characteristics of livestock in this file are obtained, and the presence or absence of other livestock data having data matching these is checked. If yes, the nose print data is compared with the collected nose print data,
Confirm that the same data is not associated with other owners except for the certified purchaser. If the registered noseprint is not a registered noseprint associated with the other owner, the collected noseprint data is added to the livestock individual information of the livestock data file n and encrypted with the encryption key of the key data 4-4. It is stored in the file storage unit 4 as a livestock data file n. Also TS
Notify the registrant of the value of 2 confidentially.

Next, the authentication operation will be described with reference to FIG. The person in charge selects the nose print authentication icon on the screen of the display unit 8. After inputting the decryption key, enter the management number of the applicant declaration and TS2 according to the screen instructions. Thereby, the index file is decrypted, the record corresponding to the management number is accessed, the coincidence of the TS2 value in the record with the input TS2 value is confirmed, and the livestock data file name n in the record is confirmed.
Get.

Next, the sensor unit of the nose print sensor 1 is applied to the nose of the domestic animal to be authenticated according to the screen instructions to generate nose print data in the same manner as described above. The nose print data is compared with the nose print data of the file n. If the nose print data coincides with each other, a message indicating that the owner indicated in the record m of the owner file associated with the file n is output. The coincidence determination is performed, for example, based on whether the degree of coincidence of the feature data is equal to or greater than a predetermined value. The authentication result is stored in the authentication result log 4-6.

Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 4 is a block diagram of the authentication device 10 and the registration device 20 according to the present embodiment. Authentication device 1

The nose print authentication program 14-3 creates nose print data of the livestock to be authenticated, decrypts the authentication data 14-5 with the public key 14-4, compares it with the nose print data thus created, and possesses the livestock. Authentication process.

The protection mechanism 31 has a flag 31-2 and a switch 31-1. The flag 31-2 is a storage element (flip-flop) that is always driven by a battery regardless of whether the power of the authentication device 10 is on or off. Switch 31-1
Is attached so as to be pressed down when the shield case 32 is closed. In this state, a set gate input and a hold input are supplied to the flag 31-2.

These components are connected by a bus 15, and a part other than the nose print sensor 1 is used as a data processing unit and housed in a shield case 32. Shield case 32
Is a case of the body of the authentication device 10 and is composed of a case and a lid,
The fitting part of both is inside, so that the disassembly procedure and procedure cannot be clarified from the appearance of the closed casing.

The main body of the authentication device 10 is a portable device that is driven by a battery, is compactly assembled as a whole, and is easy to carry. Further, a nonvolatile memory 14 such as a flash memory is used as a built-in auxiliary memory, and it is considered that the storage device and its stored data are not destroyed even if it is shocked by dropping.

Next, the configuration of the registration device 20 will be described. The data input unit 29 is a keyboard or an OCR input device for inputting livestock individual information, owner information, and other operation instructions. The input information is confirmed on the display unit 28. The file storage unit 24 is a non-volatile storage unit, and includes an operation program 24-1 such as an OS that performs basic operations, a nose print registration program 24-2, a secret key 24-3, individual data 24-4,
The authentication result log 24-5 is stored. Individual data 24-4
Is a set of data in which the management number (k), owner information, livestock individual information, and nose print data are collected for each livestock individual. The communication adapter 26 is a line modem for communicating with the authentication device 10 and other processing devices.

The nose print registration program 24-2 checks the validity of the owner information and livestock individual information input from the data input unit, and associates these information with the registered nose print data received from the authentication device 10 to obtain the individual information. The data is registered in the file storage unit 24 as data, authentication data is created from the individual information data, and distributed to the authentication device 10.

The registration of the authentication data is performed by the authentication device 10 and the registration device 20 communicating with each other using the respective communication adapters 16 and 26. First, owner information and livestock individual information are input from the data input unit 29 and confirmed on the display unit 28. Next, the nose print of the domestic animal is read by the nose print sensor 1 of the authentication device 10, encrypted with the public key 14-4, and sent to the registration device 20 by the communication adapter 16.

The registration device 20 decrypts the information with the secret key 24-3, adds the owner information together with the input individual information of the livestock, and stores it as individual data 24-4 in the file storage unit 24. At the same time, authentication data is generated based on the individual data 24-4, encrypted with the secret key 24-3, and transmitted to the authentication device 10 using the communication adapter 26. The authentication device 10 stores the authentication data in the nonvolatile memory 14.

Although the encryption method using the public key and the secret key is a concept well known to those skilled in the art, its features will be described. Here, what is called a key is numerical data for encryption and decryption. Public key encryption is
Data encrypted with a public key can be decrypted only with a private key, and similarly, a text encrypted with a private key can be decrypted only with a public key. The present invention utilizes this characteristic to construct an authentication system with a safe and simple configuration.

For example, encryption and decryption are performed using the known RSA encryption as follows. Let N be the product of two prime numbers p and q of about 5 or 6 digits and L be the least common multiple of (p-1) and (q-1). , And e and d are obtained such that the remainder obtained by dividing their product by L is 1. The public key is (e, N) and the secret key is (d, N). High-speed exponentiation of the e raised to the power e is performed on the plaintext M, the result is divided by N, and the remainder C is used as a ciphertext. When the ciphertext C is raised to the power d and divided by N, the remainder becomes M and is decrypted. Here, for example, the nose print data may be divided into about four bytes from the beginning, and each word may be sequentially encrypted as plaintext M.

Although the configuration of the second embodiment has been described in detail above, the CPUs 12 and 22, the main memories 13 and 23, and the communication adapters 16 and 26 in FIG. 4 are well known to those skilled in the art. Since it is not directly related, the detailed configuration is omitted.

The communication between the authentication device 10 and the registration device 20 is performed by connecting the communication adapter 16 to a wireless telephone,
By communicating with the registration device 20 via a public line, a noseprint can be collected and authenticated even in a place where there is no line connection port (modular jack). When the registration device 20 communicates with the server in the office and the authentication device 10 through the Ethernet LAN, the communication adapter 26 is an Ethernet adapter.

Next, the operation of the second embodiment of the present invention will be described with reference to the drawings. First, the registration device 20 shown in FIG.
The registration operation by the authentication device 10 will be described with reference to FIG.

The person in charge of registration activates the nose print registration program 24-2 from the data input unit 29 of the registration device 20, and inputs the owner information and livestock individual information reported or described by the applicant by key-in or OCR.

Next, as in the first embodiment, the owner information is automatically accessed to a device having a livestock cooperative member database or a resident database, and its validity is confirmed. Also, the validity of the occupation for each type of livestock declaring ownership and the livestock on the female side of the parent when it is described as self-childbirth are automatically checked in this system.

If there is no doubt in these checks, the owner information and the livestock individual information are additionally given a reception control number (k), and are additionally stored as individual data in the individual data group 24-4. At the same time, the current date, time (hour, minute, second) are read out from the clock 27, and are read out by the time stamp 1 (T
S1) and stored. The registration applicant who has obtained the management number and the time stamp 1 requests a noseprint collection of the target livestock immediately or at a new date.

The person in charge of collecting the nose print can carry out the authentication device 10 and the nose print sensor 1 and go to a barn or a farm. The person in charge starts the registered nose print data creation / transmission program 14-2 from the display unit 18 and the pointing device 19 of the authentication device 10, and inputs the management number of the applicant declaration and TS1. The nose print of the livestock to be registered is read by the nose print sensor 1 of the authentication device 10. After the normalization processing as in the first embodiment, the feature data is added and the nose print data is created. The creation time is obtained from the clock 17 and set as TS2. The management number, data obtained by attaching the nose print data and TS2 to TS1 are encrypted using the public key 14-4, and transmitted to the registration device 20.

After receiving the data, the registration device 20 determines that the data is encrypted based on the extension of the received data file, decrypts the data with the secret key 24-3, and stores the management number, TS1, the nose print data, Separate to TS2. The individual data group 24-4 is indexed by the management number (k), the corresponding individual data is obtained, and the coincidence between its TS1 and the received TS1 is confirmed.

Also, it is checked whether there is any other individual data that includes the same nose print data as the received nose print data and data that includes owner information different from the owner information of the individual data. However, there is no problem if the different owner is the source of the livestock and it is certified.

When these are confirmed, the nose print data is added to the individual data and stored in the file storage means 14. At the same time, authentication data is created, encrypted with the secret key 24-3, and transmitted to the authentication device 10. The authentication device 10 stores the authentication data in the nonvolatile memory 14.

When a noseprint authentication registration system is configured by a plurality of authentication devices 10 to one registration device 20, the keys to be disclosed to each authentication device are different, and the authentication data is transmitted from the registration device 20 to each authentication device. When sending, the secret key is replaced with the corresponding one and encrypted.

Next, the authentication operation of the authentication device 10 of FIG.
This will be described with reference to FIG. The person in charge is the display unit 1 of the authentication device 10.
8. The nose print authentication program 14-3 is started from the pointing device 19, and the management number of the applicant declaration and TS1 are input. When the nose print of the livestock to be authenticated is read by the nose print sensor 1, the nose print data is created in the same manner as described above.

The authentication data indexed by the management number in the authentication data group 14-5 is decrypted with the public key 14-4 and collated with the read nose print data. At the same time, the decoded TS2 value is compared with the input TS2 value. If the matching degree of the nose print data comparison result is equal to or higher than a predetermined level and the TS2 value also matches,
It indicates that the possession of the person indicated in the owner information of the authentication data is to be authenticated. Further, these verification results are encrypted with the public key 14-4 together with the time information, transmitted to the registration device 20 and stored in the authentication result log 24-5, so that the record of the authentication result can be confirmed using the registration device. . Note that the authentication determination may be performed based only on the result of the collation of the nose print data.

As described above, according to the present invention, since only the encrypted authentication data and the public key are stored in the authentication device, the individual information of the livestock is safely protected and the authentication device is simple. It can be realized with a simple configuration.

Next, the security function of the authentication device 10 will be described. Operation program 1 when this device is powered on
The operation of the initial startup program in 4-1 starts.
After completing the primitive setting of the display unit 18 and the pointing device 19, the initial startup program checks the flag 31-2. This flag indicates that the authentication device 10
When the initial password is set when the main body is used for the first time after purchase, the set input is supplied from the CPU 12 as one of the I / O ports through the bus 15, and the switch is turned on at that time. Thereafter, the hold input and the set gate input are performed from the switch 31-1. Since it is supplied, the on state is maintained unless the shielded case 32 is opened. Therefore, in a normal start-up, the initial start-up program is checked OK, the OS is started up without displaying anything, and the processing shifts to loading of the registered nose print data creation transmission program 14-2 and the nose print authentication program 14-3.

When the OS and the program are started, a normal password is required, and the system does not start unless the same word as the registered reference is input, thereby preventing the system from being started by an unauthorized operator.

When the authentication device 10 is stolen and the unauthorized person does not know the normal password and opens the device to read the contents of the non-volatile memory 14, the switch 31-
1 is turned off, and the flag 31-2 is reset. When this state or the switch 31-1 is returned to the pressed state and the power is turned on, the initial start-up program
At the stage of checking -2, since it is off, it is checked whether the reference of the initial password is set to the specific address of the non-volatile memory 14, and if it is set, a message such as "cannot start" is output and the predetermined time is output. Stop operation after elapse.

This prevents the program and data in the nonvolatile memory 14 from being analyzed.

When such a device is collected by a valid operator, the initial startup program matches the registered reference by inputting the initial password stored in the message, so that the flag 31-1 is set. The set input is supplied, the flag is set, the OS is started, and the process shifts to loading the program.

In this way, the security of the authentication device 10 is improved.
