The present invention relates to an apparatus and method for transmitting and receiving data using a secure USB dongle.

Recently, various types of information have been converted into data that can be processed by a computer, and a method of storing data so that a large number of data can be easily processed and stored has also been diversified. In particular, the data can be stored in a simple image such as a barcode or a QR code so that data can be conveniently stored for each individual item. Accordingly, a scanner capable of easily reading data from an image storing data such as a bar code or a QR code has been developed.

Scanners are used in various fields to obtain various image information in daily life. In particular, a scanner can be used as an input device of a computer connected to a scanner, and various data can be received from a scanned image and transmitted to a computer. For example, a scanner can scan a book or document and convert it into an image or a document file, or scan a barcode or QR code displayed on a product or receipt to obtain the necessary information. In this manner, the scanner can receive important data by checking images of various shapes. For example, the scanner may scan a barcode having a rectangular array of various thicknesses to read various information contained in the barcode, and may scan additional information contained in the QR code by scanning a complexly arranged QR code .

The modules include units comprised of hardware, software or firmware and may be used interchangeably with terms such as, for example, logic, logic blocks, components or circuits.

The first connection module 210 searches for one or more connectable scanners, and obtains scanner information for the one or more scanners that are searched. Here, the scanner information may be unique information of the scanner, and may be identification information possessed by the scanner. For example, the unique information includes a MAC address, a serial number, and a class. Herein, the unique information may be transmitted to the security USB dongle 110 through short-range wireless communication, and may be transmitted to the data transmission / reception device 100 through a USB port connected to the secure USB dongle 110.

The encryption / decryption module 230 may encrypt the data to be transmitted to the scanner 120 and decrypt the encrypted scan data received from the scanner 120. For example, when specific data is selected through the input module 240 and a key value (e.g., a character) for encryption is input, the encryption / decryption module 230 encrypts the specific data Lt; / RTI > The selected data and the encrypted data can be displayed through the user interface. For example, the selected data may be displayed as plain text, and the encrypted data may be displayed as cipher text. According to various embodiments, the encryption / decryption module 230 may determine the validity of certain scan data. Specifically, when the first scan data is selected through the input module 240 and the key value is input, the encryption / decryption module 230 can output the cipher text of the first scan data encrypted by the input key value have. When the output ciphertext is compared with the ciphertext of the first scan data encrypted by the scanner 120 and transmitted by the secure USB dongle and the ciphertexts match with each other, the encryption / decryption module 230 determines that the scan data and the key value are valid And output the result through the user interface. If they do not match, the encryption / decryption module 230 may output a loss of scan data or an error message regarding the key value through the user interface.

Input module 240 receives user input and passes data corresponding to the received user input to each module.

For example, the data transmission / reception apparatus 100 may decrypt the encrypted scan data and display the decrypted scan data through a user interface. When the key value is received for decrypting the encrypted scan data, the encrypted scan data can be decrypted using the received key value. In order to determine the validity of the decrypted scan data, the data transmission / reception device 100 compares the cipher text of the received scan data with the cipher text of the scan data, And the key value is valid. The result of such determination can be displayed through the user interface.
