C. Cloud Service
The ciphered images will be sent to the Azure storage
where the images will be decrypted. Before decryption hash
code will be produced using SHA-2 to check the integrity of
the biometric traits. If the hash code is same as produced by
the RPi client before the transmission, then decryption
process takes and the original images are retrieved. The Uploading of captured biometric traits on the Microsoft
Azure Server is completed and then uploaded. Fig. 14
shows the blob storage summary of the Microsoft Azure
account. It can be seen that the two images ‘Frame_ex.jpg’
(Face) and ‘20141103_165029.jpg’ (Fingerprint) are
uploaded to the cloud service successfully.
