SQL injection prevention using tokenization: A model exclusive of tokenization technique is used to prevent SQL injection attack by blocking the malicious input query in query execution phase. SQL injection prevention using tokenization model detects SQLIA by applying tokenization process on input query. Tokenization process is applied by detecting spaces, single quotes and double dashes, etc. This process converts the input query into the fruitful tokens and these tokens are then converted into hierarchical form. After applying tokenization, model validates each token by analyzing the value of left and right child of individual token. As soon as SQLIA detected it permanently block the input query.
