OBJECTIVE

This project addresses the privacy issues and

demonstrates a solution which achieves high security

while maintains low manufacturing and maintaining

cost in RFID item level applications such as librarymanagement.

DESCRIPTION

The user enters the username and password.

If it is valid, then the user can access.

The access detail contains lending, renewal, return etc.

PROCEDURES

FIRST STEP : Request

SECOND STEP : (r,h(r//T (ID))

THIRD STEP : (r,h(r//T(ID))

FOURTH STEP : Valid / Invalid

FIFTH STEP : Valid / Invalid

(SHA) SECURE HASH

ALGORITHM IMPLEMENTATION

Hash algorithms compute a fixed-length digital

representation (known as a message digest) of an

input data sequence (the message) of any length.

SHA generates a random number, that is used forthe security purpose

The five algorithms are denoted SHA-1, SHA-224,

SHA-256, SHA-384, and SHA-512.

SHA-256 is used in this RFID structure.

VALIDATION

In this Validation phase, the database will send

whether the card is Valid/Invalid.

If the value in the database matches the value in

card then it is valid.

If the value doesn't matches then it is invalid.

DESCRIPTION

The user enters the username to the database.

Then user enters password to the database.

The admin acknowledges whether it is valid or invalid.

If it is valid then the user access the books. Then the reader request the tag.

The tag sends the data in the form of (r,h(r//T (ID)).

The reader sends the data in the form of (r,h(r//T(ID)).

CONCLUSION

We have proposed a RFID structure to address the

privacy concerns in item-level applications, where the

cost for tag manufacturing and management must be

kept low.

In the proposed system, RFID tags do not need a secret

key or a PIN for authentication, thus eliminates the

costly key distribution and management.

FUTURE ENHANCEMENTS

Our future enhancement is to detect the RFID

tags by the RFID readers and send to the database

automatically with highly equipped hardware

(Wireless).
