Systems and methods for securing data by a user input based data encryption are described. In one aspect of the invention, the method may include receiving an authentication string from a user to authenticate access to the application. On successful authentication of the user, the data to be secured is obtained from the user. The obtained data is then secured by encryption, which results in generation of a private key. The private key is then associated with the authentication string to form a first secure key. The first secure key is stored with the encrypted data in a data file. The data file is then transferred to a server associated with the application. The data file in the server is further encrypted to generate a second secure key.
