  1. 1. Information-theoretic Privacy and Secrecy in Biometric Identification and Authentication

    Författare :Linghui Zhou; Tobias J. Oechtering; Mikael Skoglund; Hideki Yagi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information theory; identification; authentication; privacy; secrecy; Informationsteori; identifiering; autentisering; integritet; sekretess; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Nowadays, biometrics are more and more deployed to reinforce traditional authentication or identification that uses keys, passwords, etc. Biometric identification and authentication have been studied from various information-theoretic perspectives, where privacy and secrecy are two important aspects.

  3. 2. Unique Biometric IDs: Governmentality and Appropriation in a Digital India

    Författare :Elida K. U. Jacobsen; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; India; biometric identification; Aadhaar; Unique ID; governmentality; appropriation; post-colonial; biopower; risk; narrative method; subjectivity;

    Sammanfattning : On a global scale, the usage of a variety of digital ID and surveillance technologies in both civic and security governance is increasingly taking place, leading to standardised forms and practices. India is implementing the largest biometric scheme in history. LÄS MER

  4. 3. Perspectives on Identification Systems

    Författare :Minh Thành Vu; Tobias J. Oechtering; Mikael Skoglund; Michael Gastpar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Identification systems such as biometric identification systems have been becoming ubiquitous. Fundamental bounds on the performance of the systems have been established in literature. In this thesis we further relax several assumptions in the identification problem and derive the corresponding fundamental regions for these settings. LÄS MER

  5. 4. Lip-motion and speech biometrics in person recognition

    Författare :Maycel Isaac Faraj; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Audio-visual recognition; biometrics; Biometric recognition; Speaker verification; Speaker authentication; Person identification; Lip movements; Motion; Structure tensor; Orientation; Optical flow; Hidden Markov Model; Gaussian Markov Model; Lip-motion; Image analysis; Bildanalys;

    Sammanfattning : Biometric identification techniques are frequently used to improve security, e.g. in financial transactions, computer networks and secure critical locations. The purpose of biometric authentication systems is to verify an individual by her biological characteristics including those generating characterisitic behaviour. LÄS MER

  7. 5. Lip-motion biometrics for audio-visual identity recognition

    Författare :Maycel Isaac Faraj; Massimo Tistarelli; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biometrics; Lip motion; Audio-visual signals; Speech recognition; Speaker recognition; Digit recognition; Image analysis; Bildanalys;

    Sammanfattning : Biometric recognition systems have been established as powerful security tools to prevent unknown users from entering high risk systems and areas. They are increasingly being utilized in surveillance and access management (city centers, banks, etc.) by using individuals' physical or biological characteristics. LÄS MER
