To achieve data storage security in cloud, bio cryptography techniques can be used. This paper presents Personal identification using fingerprint and Iris biometric technology. Usually unimodal biometric techniques are used. Cloud computing provides many resources, very convenient charged service and minimum cost computing. This leads the cloud computing to become the most dominant computing in the recent years. Even though the cloud provide secured service, it also undergoes with some security problem especially form hackers. The existing unimodal bio cryptography techniques often have limitations such as consciousness to noise, intra class consistency, data aspect and other factors. This research study presents personal identification using fingerprint, iris and cryptographic technologies.
