Cryptography is the art of secret writing. Cryptography is basically a technique which is used to enforce security standards on the data which we want to send through any network. When the data is going from source to destination then there may arise a case where some body can misuse the data, that data may also contain some important information which is not meant for anybody other than the receiver, so in these cases security becomes a must. At the sender side, the data is encrypted by using a key, and on the receiver side the encrypted data is again decrypted using another key to get back the original data. Note that the keys are kept secret. This concept of encrypting the data at the sender side and decrypting it at the receiver is Cryptography, which can provide security to the data.

Biometrics is really a new age technology which is still in its childhood when it comes to awareness and accessibility. This technology will no doubt become the largest security providing technology in the times to come. We all know that Biometric devices use the physical and behavioral character of persons to validate their individuality. Some of the common traits that are used to differentiate individuals include finger printing, retina and eye iris, the voice and the facial impressions. Some of the biometric techniques can also find the individuality on the basis of digital signature of the person. Thus we can say that if someone passes a biometric security test then he or she is surely a genuine personality.
