Privacy Preserving Fingerprint Authentication at the Cloud Server for Ehealth Services

BACKGROUND: Restricting entry and access to highly sensitive systems like e-Health services is vital to protect the privacy and confidentiality of customers. User authentication is implemented predominantly done using Bio-metric schemes. But there is a challenge in securely storing the fingerprint templates. Since fingerprints are permanent, fingerprints gettingstolen will be a serious issue.OBJECTIVE: The objective of this paper is to design a scheme to carry out the fingerprint match at the cloud server that will not compromise the fingerprints.METHODS: When users input their fingerprint, a unique key is generated and it is sent to the server for verification.RESULTS: We evaluated our proposed scheme and ascertained that it generates unique Fingerprint Identification Number for different fingerprints and the false rejection rate of our proposed scheme is within acceptable limit.CONCLUSION: The proposed scheme overcomes the security threats to the stored fingerprints of users.
