A Solution to Privacy Issues in RFID Item-level Applications
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 library management.
MODULES
There are 4 modules in the project.
GUI.
SERIAL COMMUNICATION.
SHA IMPLEMENTATION.
VALIDATION.
GUI (Graphical User Interface
LOGIN PAGE
AFTER LOGIN PAGE
LENDING PAGE
RENEWAL PAGE
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.
SERIAL COMMUNICATION
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 for the 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.
Valid Card
Invalid Card
PROCESS
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).
