Example Embodiment

[0039] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] In the following, those of ordinary skill in the art will understand that the terms "face image", "face data" and "face image data" mean the same thing, that is, a human face captured from an analog / digital camera After the image is processed, the face data corresponding to the face image is transmitted to the host computer for subsequent processing. Similarly, "eye position" and "human eye position" also have the same meaning, and those of ordinary skill in the art should understand that "human eye position" and "nostril position" refer to the left-right symmetrical two positions. any location.

[0041]First of all, before the specific description, as mentioned above, the present invention discloses a smart card-based face recognition system, in which the face data corresponding to the captured face image is recorded on the ...

Abstract

The invention discloses a face recognition method based on an intelligent card, which comprises the following steps: acquiring and transmitting face data; judging the quality of the face data; adjusting the brightness for the face data with qualified quality; extracting face features, and transmitting the face features to the intelligent card by an encrypted way; and comparing the face images, anddetermining whether the identification passes or not. The invention also discloses a face recognition system which comprises a face detection module, a data safety communication module, a face imagequality judging module, a face image brightness adjusting module, a face feature extracting module and a face verification module. By adopting the system and the method of the invention, the defect ofthe reduction of the recognition effect caused by attitude deviation is eliminated, and the recognition rate is greatly improved. In addition, in the process of comparing the face images, the writingspeed, the reading speed and the operating speed of the compressed face image data are quick, thereby meeting the requirements of various real-time application conditions.

Description

technical field [0001] The invention relates to a face recognition system and method thereof, in particular to a face recognition system using a smart card. Background technique [0002] In the current information age, the amount of information in the process of human interaction is increasing, and the number of information interactions is becoming more and more frequent. In the process of people exchanging information, identity authentication is an essential step. As we all know, personal identity can generally be proved by valid certificates held by itself, for example, resident identity card, social security card, work permit and so on. However, due to the increasingly rampant criminal activities of counterfeiting and fraudulent use of documents, people have higher and higher requirements for anti-counterfeiting of documents, and the traditional document manufacturing technology has been far from meeting the needs of social development. Moreover, the improvement of anti...
