Indoor positioning technology and its accuracy are crucial research topics for ubiquitous computing. While the GSM-based approach has always been used to provide outdoor positioning to compensate the lost of GPS in urban area, we seldom see systems that utilize the GSM-based approach for indoor positioning. On the other hand, the WLAN-based approach is(More)
Biometric security has been largely regarded and researched within the latest 20 years. However, researchers focus in face recognition have not paid enough attention to the security of face biometric data. We propose a cryptographic algorithm to protect face recognition process against attack, which applies the error-correcting codes. The original face(More)
