description Disclosed are an apparatus and method for generating an image in which information is encrypted in one direction. According to the present invention, an encrypted image processing apparatus comprises: a hash code generation unit which receives arbitrary information and generates a hash code encrypted with a fixed length by a predetermined hash function; a hash code division unit for dividing the input hash code into a plurality of character string blocks; and an image processing unit which converts the hash code into an encrypted image by determining a phenotype of a plurality of unit elements corresponding to each of the plurality of character string blocks. 정보를 단방향으로 암호화한 이미지의 생성 장치 및 방법이 개시된다. 암호화 이미지 처리 장치는, 임의의 정보를 입력 받아 소정의 해시 함수에 의해 고정된 길이로 암호화된 해시 코드를 생성하는 해시코드 생성부; 입력된 상기 해시코드를 복수의 문자열 블록으로 분할하는 해시코드 분할부;및 복수의 문자열 블록 각각에 대응하는 복수의 단위요소의 표현형을 결정함으로써 상기 해시코드를 암호화 이미지로 변환하는 이미지 처리부를 포함한다.
