  1. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 Myung Geun Chun Chungbuk National University Korea Dec. 7 2010 This work was supported by the  ICT  Standardization program of MKE(The Ministry of Knowledge Economy). Addressing security challenges on a global scale

  2. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 • ISO/IEC JTC 1/SC 27 WGs Addressing security challenges on a global scale

  3. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 • ISO/IEC JTC 1/SC 27/WG 5 Major Works Addressing security challenges on a global scale

  5. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 • ISO/IEC 24745 “Biometric Information Protection” • analysis of the threats to and countermeasures inherent in biometric system application models; • security requirements for securely binding a biometric reference with an identity reference • biometric system application models with different scenarios for the storage of biometric references and comparison; and • guidance on the protection of an individual’s privacy Addressing security challenges on a global scale

  6. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 . Name . Social security number . Driver license’s number . etc Identity reference . Fingerprint image . Face image . Ordered set of fingerprint minutiae . etc Biometric reference • Biometric reference: one or more stored biometric samples, biometric templates or biometric models attributed to a biometric data subject and used for comparison • Identity reference: an identifier with a value that remains the same for the duration of the existence of the entity in a domain Addressing security challenges on a global scale

  7. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 • Security Requirements for biometric systems • Confidentiality: protect biometric information against unauthorized access or disclosure • Integrity: safeguardthe accuracy and completeness of biometric information • Renewability and revocability: provide the means to resolve compromised biometric references, and not for compromised biometric characteristics. A major security and privacy concern for biometric systems relates to the compromise of biometric references Addressing security challenges on a global scale

  8. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 • Architecture for renewable biometric Addressing security challenges on a global scale

  9. Biometric Information Protection Standard in ISO/IEC JTC 1/SC 27 • Biometric information privacy requirements and guidelines • Irreversibility: biometric data shall be processed by irreversible transforms before storage -> Encryption/psedonymous identifier • Unlinkability:Stored biometric references should not be linkable across applications or databases. ->Encryption with different keys/diversification process • Confidentiality: To protect biometric references against access by an unauthorized outsider resulting in a privacy risk, biometric references shall be kept confidential. -> Data separation/encryption of biometric references Addressing security challenges on a global scale
