Abstract

A method implemented by a microprocessor for securing data, receiving an authentication string from a user as input for authenticating the user to access an application; obtaining the data from the user during authentication for protecting the data, wherein the protection comprises encrypting the data, encrypting to generate encrypted data and a private key; associating the authentication string with the private key to generate a first safety key; storing the encrypted data in a data file, wherein the first safety key is stored in the data file together with the encrypted data; and transmitting, by the microprocessor, the data file to an application server associated with the application for encrypting the data file, the encryption of the data file generating a second safety key.

Description

technical field [0001] The invention relates to a data security method and system. Background technique [0002] In today's digital world, large amounts of data are generated, stored and transmitted on communication networks every day. Data can include confidential information such as credit card numbers, contact numbers, financial details, personal information, commercial information, and technical information. Therefore, various data security methods are used to reduce the possibility of unauthorized data access and use. Encryption or cryptography is one such method that helps to protect data stored in a system or in transit. The use of encryption enables the transformation of data, such as plaintext, in a form called ciphertext, which cannot be easily read by unauthorized users. When needed, the ciphertext can be converted to the original plaintext by decryption. [0003] Typically, encryption is achieved through the use of cryptographic algorithms, which are essentia...
