INFORMATION ENCRYPTION SYSTEM AND INFORMATION ENCRYPTION METHOD USING OPTICAL CHARACTER RECOGNITION

摘要

An information encryption system and an information encryption method for encrypting character information and decrypting the encrypted information by using optical character recognition includes a user terminal comprising: a viewer region display unit for displaying a viewer region at the very top of a screen; a viewer character recognition unit for recognizing in real-time characters displayed on a screen region covered by the viewer region, a viewer character encryption unit for generating an encrypted character by encrypting a first character to be encrypted by using a cipher when the first character is recognized; an encrypted character substitution unit for deleting the first character and substitutively inputting the encrypted character; and a viewer character display unit for displaying a non-encrypted second character as it is, and decrypting an encrypted second character by using a cipher and displaying the same in an original character when the second character to be displayed is recognized.

1. An information encryption system comprising:
a user terminal comprising:
a viewer region display unit configured to display a viewer region on foremost of a screen;a viewer character recognition unit configured to recognize at least one character displayed on a screen region covered by the viewer region in real time using optical character recognition;a viewer character encryption unit configured to encrypt, when the recognized character is a first character to be encrypted, the first character using a password set by a user to generate an encrypted character;an encrypted character replacement unit configured to delete the first character, and instead, input the encrypted character; anda viewer character display unit configured to display, when the recognized character is a second character to be displayed, the second character which is non-encrypted as it is, and decrypt the second character which is encrypted, using the password, to display an original character.
