This technique uses a special action called a challenge. The system works to verify that the challenge occurred during a video sequence. A challenge-response system relies on a series of challenges to validate an individual’s identity. These challenges can include: Smiles Facial expressions of ...
Here, each technique is discussed in terms of its implementation, strengths and limitations, as well as indications on possible future research directions that can be studied.doi:10.18520/CS/V108/I8/1491-1500Sajida ParveenSharifah Mumtazah Syed Ahmad...
This system can be combined with the face recognition technique to avoid the RFID is used by unauthorized people. However, this approach also suffers a drawback that someone may try to deceive the security system by presenting a photo of the real card owner. In this paper, we propose a ...
Finishing the Classifier Design of Spectroface Human Face Recognition; 完善频谱脸人像识别的分类器设计 3. This paper proposes a technique based on Spectroface and moment in va riants for face recognition. 提出了基于频谱脸和不变矩的人脸识别方法。补充资料:脸谱化 1.比喻文艺创作中刻划人物的公式化...
and prevent such a situation from occurring again. There is no clear mention of multi-factor authentication or rather any specific authentication technique that healthcare providers have to implement to ensure that only a limited set of individuals can access this data. Instead, the focus is ...

a technique known as alternative lengthening of telomeres (ALT) [93]. In osteosarcoma and bread cancer cell lines, the potential relationship between telomere lengthening and inhibition of tumor growth is cleverly orchestrated in cell lines that maintain telomere length by the ALT [94]. It helps ...
[187]. Detecting the heart rate from a face video is another method for liveness detection[196,254]. This technique is called as remote (non-contact) photoplethysmography, which utilizes the subtle color changes of the skin, which occur each time the heart beats and pumps blood to the body...

there exists a vital threat to these face interaction systems. Imagine a scenario where an attacker with a photo or video of you can unlock your phone and even pay his bill using your e-wallet. To this end, face anti-spoofing has emerged as a crucial technique to protect our privacy and...
