System security device and method using angle of refraction right}

The present invention relates to a system security device and method using a refractive index of light, in particular, there is no risk of leakage of the password can further improve the system security effect, the simple configuration of the security device is low production cost, the scope of application The present invention relates to a system security apparatus and method using a refractive index of light, which can be expected to have an excellent effect in preventing the illegal use and duplication of software by further expanding.

Many people are currently using the Internet, and the dissemination of the Internet has prompted users to globalize through the transmission and sharing of information through computers.

In the Internet, several systems are connected to each other in the Internet network to share data by communicating with each other. In order to obtain information stored in other systems, the system must be connected to the system.

Most systems allow users to enter their own ID and password to access their system.

However, such a cryptographic system has a problem that can be obtained by accessing the system unlimitedly when another person acquires the user's ID and password, many security companies provide various system security devices.

Examples of security devices provided by existing system security companies include a security device using fingerprint recognition, a smart card security device using a separate smart card that stores information about a user, and an iris recognition security device that identifies a user's iris. Can be mentioned.

The fingerprint recognition security device recognizes the user's fingerprint and grants access to the system. It is recognized that the security effect is increased by using all the different fingerprints, but to use the system, the user uses the system. There was a problem that the inconvenience of using the fingerprint reader must be installed.

The smart card security device has the advantage that the information does not leak as long as the user carries the smart card, but this smart card is easy to duplicate and leads to read the information recorded on the smart card in the system to be used by the user. There was a problem that must be installed,

The iris recognition security device recognizes the user's iris and permits access to the system. However, the iris recognition security device has a high security effect, but the price of the system is very expensive, and thus it is generally not widely used.

Therefore, the proposed invention to solve the above problems is to combine the plurality of unit cells that refracted light at different angles to form a decryptor to distribute to the user, when viewed through the decoder when the user accesses the system By outputting the password image to be displayed as normal characters or figures on the screen to allow the user to decrypt and input the password to allow the user to access the system, there is no risk of leakage of the password, further improving the system security effect, The simple structure of the security device makes the production cost cheaper, and the purpose of the present invention is to provide a system security device and method using the refractive index of light, which can be expected to have an excellent effect in preventing the illegal use and copying of software by expanding its application range. It is done.

Hereinafter, with reference to the accompanying drawings 1 to 9 as follows.

1 illustrates a system security apparatus of the present invention, and FIG. 2 illustrates a decoder 5 applied to the present invention so that a plurality of terminals 1 can access the system 2 through an internet network. It is comprised and the encryption surface generation part 4 is connected to the system 2.

Each user accessing the system 2 is given a unique ID and password, and the system 2 stores the ID and password of the user to confirm the ID and password input by the user when the user accesses to permit access. .

Each user is provided with a decoder 5 as shown in FIG. 2, which is provided with a plurality of unit cells for refracting light at different angles formed as shown in FIGS. 6) is arranged to be a flat plate of a predetermined size so that the incident light is refracted at different angles by the unit cells 6.

The size of the decryptor 5 is preferably formed to a size that the user can carry.

Each unit cell 6 is formed of a transparent material that transmits light, and the inclined surfaces 7a, 7b, and 7c are formed at different angles to change light incident on one side thereof to a predetermined angle.

A plurality of unit cells 6 as described above are combined and arranged to form a flat plate as shown in FIG. 2 to form a decoder 5, and the light of the decoder 5 is changed as the arrangement order of the unit cells 6 is changed. The angle of reflection is changed.

The produced decoder 5 has a different arrangement order of the unit cells 6 so as to have different angles of light reflection, and the light reflection characteristics of the produced decoder 5 are encrypted. The serial number is assigned to the upper part of the decryptor 5 produced for storage in the encrypted surface generating unit 4, and the serial number and light reflection of the decryptor 5 owned by the user in association with the user's unique ID. This will save the property.

The encryption surface generating unit 4 receives the user's unique ID from the system 2 when the user inputs a unique ID and password when the user's system 2 is connected to the serial number of the decryptor 5 owned by the user. Finds and generates an encryption surface corresponding to the light reflection characteristic of the serial number of the retrieved decoder 5 and transmits it to the terminal 1 of the user.

The encryption surface is output in a form in which a plurality of encryption pixels are irregularly arranged as shown in (a) of FIG. 4, and the arrangement rule of the encryption pixels is a decoder (5) when viewed by the user with a decryptor (5). It is set to be displayed as a normal character or figure by the light reflection angle of).

That is, the arrangement of the encryption pixels represented on the encryption surface is calculated by reversing the light reflection angle of the decoder 5 so that each encryption pixel is refracted by the unit cell 6 of the decoder 5 corresponding thereto. , The size of each encryption pixel is preferably set equal to the size of the unit cell 6.

FIG. 4B illustrates a state in which the user reads the encryption surface with the decryptor 5, and FIG. 4A is an encryption surface generated by encrypting the character 'Aiki'. If you look at the decryption (5) as shown in Figure 4 (b) 'Aiki' characters will appear exactly.

5 shows an operation state of the decryptor 5, in which the encryption surface generated by the encryption surface generating unit 4 is displayed on the user's terminal 1, and in this state, the user inserts the decryptor 5 into the terminal. When it comes in close contact with the screen of (1), each ahopixel constituting the encryption surface is refracted according to the light reflection angle of the unit cells 6 constituting the decryption device 5, whereby the user Through the decryptor 5, the encrypted pixels are arranged in order, that is, the normal encrypted characters can be viewed.

The operation of the system security apparatus of the present invention configured as described above will be described in detail with reference to FIGS. 6 to 9.

First, the system 2 sets a unique ID and password for a plurality of users who allow access, stores the unique ID and password, and assigns a decryptor 5 having a different serial number to each user. Distribute.

At this time, the encryption surface generation unit 4 stores the user's unique ID and the serial number of the decoder 5 in association with each other, and stores the light refractive index of the decoder corresponding to each serial number, and then the user accesses the system. In order to input the unique ID, the unique ID is used to determine the refractive index of the light decoder owned by the user so that the corresponding encrypted image can be generated.

When the user tries to access the system 2 via the Internet network or the data communication network using the terminal 1, the system 2 outputs the main screen for connection to the user terminal 1 as shown in FIG. Overlaid on the main screen, and outputs a password input screen for the user to enter the ID and password.

When the user inputs his or her unique ID and password on the password input screen, the system 2 determines whether the ID and password entered by the user match the stored information, and if it is determined to match, the user inputs. A unique ID is supplied to the password screen generation unit 4.

The encryption surface generation unit 4 searches the serial number of the decryptor 5 owned by the user as the ID inputted from the system 2 to find out the light refraction characteristics of the decryptor 5 owned by the user. The decryptor 5 generates and outputs an encrypted image decipherable.

The encryption surface output from the encryption surface generation unit 4 is superimposed on the main screen output to the user terminal 1 as shown in FIG. 8. Referring to FIG. 8, several encryption pixels are irregularly formed on the encryption surface. You can see that they are arranged, and these encrypted pixels encrypt the character 'Hello My love'.

As described above, if the user deciphers the decoder 5 owned by the user with the encryption surface as shown in FIG. 9 while the encryption surface is output to the user terminal 1, the encryption pixels irregularly arranged on the encryption surface. They are refracted according to the light refraction characteristics of the respective unit cells 6 constituting the decoder 5 to be seen by the user.

The cipher text shown to the user through the decryptor 5 is shown as the character 'Hello My love' as shown in Figure 9, when the user who recognizes the cipher text enters the decrypted cipher text, the system 2 The inputted ciphertext is compared with the ciphertext generated by the encryption surface generating unit 4, and if the ciphertext is matched, the user is then connected to the system.

On the other hand, the encryption surface generating unit 4 changes the cipher text generated each time users access to further increase the system security efficiency.

In other words, even if the same user wants to continuously access the system 2, the encryption surface generating unit 4 generates an encrypted image having different characters or figures at that time, thereby greatly improving the system security efficiency.

By using the present invention operating as described above, by entering a unique ID and password to the user who wants to access the system to perform the first security, and then generates and outputs a password image pattern corresponding to the user's ID Secondary security can be implemented by decrypting the cipher text by the user's own decryptor (5), so that the user can implement a better security effect. It will be able to maintain security.

In addition, the present invention described above can be effectively used to prevent illegal use and duplication of software.

That is, when the manufacturer stores and distributes the software on a recording medium such as a CD or a diskette, the encryption decoder is distributed together with the recording medium, and when the recording medium is executed on the recording medium, an encryption surface generating unit is installed on the system. If you install a program to be installed, a different encryption screen is generated and printed out every time the user runs the software, so that the person who does not have the decryptor can never use the software, thereby copying the software. Even if the software is not used at all, it will prevent duplication.

As described above, the present invention combines a plurality of unit cells that refract light at different angles to form a decoder and distribute it to a user. By outputting the password image to be displayed on the screen to allow the user to decrypt and input the password to allow the user to access the system, there is no risk of leakage of the password, further improving the system security effect, and the configuration of the security device It is simple and low production cost, and can be expected to provide a system security device and method using the refractive index of light that can be expected to have an excellent effect in preventing the illegal use and copying of software by expanding its application range.
