Abstract:
The objective ofthis project is to develop a security system that helps to prevent data
from theft or hackers in order to maintain confidentiality and integrity. This report tells
about the system and its components and how it works. Different cryptographic
algorithms are used in Java language like OPE, AES and Unstructured (NoSQL) and
(SQL) Databases are used like MongoDB and XAMPP (MySQL)for storing records.
The system first prompt user to input data which is in plain text form then the data will
be encrypted according to the algorithm which fits best for the data and then it will be
stored in the database.
When the user requests for the data, the request is then sent to the system, the
query is then performed on the encrypted information according to the users request
and then sent to the system where it decrypts and then delivered to the user.
This system is very useful as there is processing of query on the encrypted data
and it helps to maintain the confidentiality and integrity of data because if someone
hacks the database then he/she will only have the encrypted information which is not
useful for him/her because he/she doesn't know what this information is all about
because all of the information is in encrypted and without the key no one can decrypt
it
