In networking society, advancement in the internet based electronic applications and cloud computing services need higher level of user authentication and information security. Ensuring security with shared secrets like passwords, smart cards is not reliable as they are prone to theft and misuse. Biometrics offers an advantage over knowledge and possession based methods as these characteristics are distinctive to each and every person. Usage of multiple biometric modalities offers better accuracy for authentication which can be utilized in cryptosystems for securing confidential data. Storing the information on local storage devices involves huge capital costs needed for hardware, software or licensing. Hence the encrypted information can be stored securely on a globally available storage “cloud”. This paper proposes a novel model for secure information storage and retrieval from cloud using multimodal biometric cryptosystems. The designed system efficiently authenticates the user and protects the information through multimodal biometric cryptosystems and reduces the storage infrastructure requirement of the electronic applications by using securely the cloud storage.
