Description
本發明係關於一種辨識分析相關領域,尤指一種身分辨識系統。The present invention relates to the related field of identification analysis, in particular to an identity identification system.
隨著人工智慧的發展,深度學習(Deep Learning)使用CNN影像辨識有了非常大之進步,因此人工智慧中影像辨識(product recognition)用於人臉辨識,變得是一件非常具有挑戰性與意義之工作。With the development of artificial intelligence, the use of CNN image recognition in deep learning has made great progress. Therefore, the use of product recognition in artificial intelligence for face recognition has become a very challenging and difficult task. The work of meaning.
目前人臉辨識的應用大致可分為以下6種方式:1.門禁系統:透過人臉辨識系統辨識進入者的身分;2.影像監視系統:在公共場所對人群進行監視,達到身分識別的目的;3.網絡應用:利用人臉辨識技術防止非信用卡擁有者使用;4.學生考勤系統:學校利用智慧卡配合人臉辨識來進行點名,紀錄學生 的出席紀錄;5.相機:新型的數位相機內建的人臉辨識功能可以輔助人物拍攝時對焦;6.智慧型手機:運用於解鎖手機、識別使用者。At present, the application of face recognition can be roughly divided into the following 6 ways: 1. Access control system: identify the identity of the entrant through the face recognition system; 2. Image surveillance system: monitor the crowd in public places to achieve the purpose of identity recognition 3. Network application: use face recognition technology to prevent non-credit card owners from using it; 4. Student attendance system: the school uses smart cards to cooperate with face recognition to carry out roll call and record students’ attendance records; 5. Camera: a new type of digital camera The built-in face recognition function can assist in focusing when shooting people; 6. Smart phone: used to unlock the phone and identify the user.
然而,一般透過人臉辨識作為身分核對時,由於人臉辨識系統是以單一影像作辨識,無其他輔助辨識標的,所以並不侷限須以動態影像作為辨識標的物,所以利用照片作為辨識標的物亦是可行,但是利用照片作為辨識標的物,可能會被人臉辨識系統視為認證其身分,因而會發生以照片方式蒙騙人臉辨識系統,而導致身分被冒用;因此,目前人臉辨識系統作為身分核對時,可能潛藏的身分冒用風險。However, when face recognition is generally used for identity verification, since the face recognition system uses a single image for recognition without other auxiliary recognition targets, it is not limited to use dynamic images as the recognition target, so photos are used as the recognition target. It is also feasible, but using a photo as an identification object may be regarded by the face recognition system as authenticating its identity, so photos may be used to deceive the face recognition system, resulting in the identity being used fraudulently; therefore, the current face recognition system When the system is used for identity verification, there may be a risk of potential use of hidden identities.
為解決上述課題,本發明提供一種身份辨識系統,利用臉部影像搭配人體特徵,增加辨別的複雜程度,降低被冒用身分的機會。In order to solve the above problem, the present invention provides an identity recognition system, which utilizes facial images to match human body features to increase the complexity of identification and reduce the chance of being fraudulently used.
