File Security System Java Project

Abstract: In this File Security System application we mainly show’s that how to store the file with security using Encryption algorithms. The user will login to the application by giving a valid email id of whom the file security key must be sent. After successful login the user will upload the file the file will encrypt and stored in the given path and security key sent to given mail id.The user will download the decrypted file by giving security key which is received in user mail id.

The application has the only one module


The user will login to the application by giving username and password and the valid mail id. After logging the user will upload the file and the file will be an encrypted security key is send to mail id and if he wants to decrypt the file he needs to enter the security key which is sent to mail id and select the encrypted file.

Existing System:

In previous applications there we need to store the file in the database and encrypt the file. Storing the file in the database is not secure so to overcome the existing system we developed this application.

Proposed System:

In the Proposed system, we will not store the file in the database so there is no issue in unsecure of a file. The person who is having decryption key must also have the encrypted file to decrypt the file.

Online Survey System Java Project


The main aim of developing this online survey system is to conduct an online survey on different topics to the users. In this Java Application, the user can take part in various online polls. Admin in this application will add the polls regarding different questions and different topics and he can see the results of each poll in the pie chart.

Existing System:

In Existing System user can poll the votes more than once. Then We cannot get the results of the exact poll that results in manipulation of results.

Proposed System:

In the Proposed system user can vote only once and after that, he tries to vote it says you are already voted.

Customer Support Service Operations Synopsis

Project Title:  Customer Support Service Operations

Category: Application Development, Enterprise.

The goal of the project entitled “Customer Support Service Operations” is to report and track the problems that have occurred in the system. This application is used in many areas and report back the error to the administrator. The administrator will check the error and sends a report to the vendor regards the generated errors.

The user in different locations sent their complaints to the administrator giving the complaint, type, date/time of occurrence of the problem and their location. These details are stored in the inbox of the administrator. The administrator checks the complaint. The service charge is free until the guarantee period expires.

Users can complain at any time to the administrator and he in turn reports to the vendor.

MNZ is a distribution company dealing in electronic testing and measurement equipment. Every time a customer calls into log in a problem with respect to one of the product purchased from MNZ, there is an opportunity to retain that customer forever providing fast, responsive and effective customer support. MNZ deals with different types of products such as process control, material testing and heat sensing.

The starting cycle for customer support is installed. When a product is installed it gets an installation ID. With this, the client would interact with MNZ. When a client calls the customer support division to register a complaint they quote their ID. Then this call is assigned any CSE who is available in the office, if not the call is assigned to nearest CSE with I the client location. CSE’s are expected to provide the customer support within a period of time.

If for a specific service call, spare parts are required then CSE will go to MNZ stores and fill in the spare request form. This form will quote the installation number with client/site and product details and specify the part number for the specific spares of the product. If the product is under warranty, then spares are supplied without charging anything extra.
