Font Level Tainting: Another Approach for Preventing SQL Injection Attacks

the font level tainting is the another new approach for preventing sql injection attacks, that involves comparing the meta strings library with the sql statements that includes the characters including the different font levels in the user input, to prevent them if found any and protecting the web applications against sql injection is discussed in this paper. this paper includes the strange idea of combining the declarative method and the quest method. sql injection is the main problem that occurs with web application security. it gives the attackers unauthorized access to the database containing the web applications which in turn leads to the cause of defects in the web applications. this is very serious. in declarative method point of view, it exhibits detection mode for sql injection, that uses the coupled way routing arrangement of amino acid code formulated from web application form parameter sent via the web server. on the other hand from the quest method point of view, it analyzes the transaction to find out the malicious access. in declarative method it uses an approach called schatten algorithm, not only to prevent the sql injection attacks, but also reduces the time and space complexity. this system was able to stop all of the
