Description:DESCRIPTION:
Field of the invention:
[0001] The present disclosure generally relates to the technical field of security software for transfer files, and specific relates to a system and method for multi-layer secure file sharing over communication networks using cryptography techniques and a dual OTP authentication system to enhance the level of security further.

Background of the invention:
[0002] Secure file sharing is the practice of transferring digital files between two or more systems while maintaining the confidentiality, integrity, and availability of the data being shared. The current data transmission gateway can only realise the transparent transmission characteristic of data, and the security of the data is dependent on the processing of the terminal equipment. To maintain the security of data transmission, terminal equipment makers use a predetermined secret key to encrypt the system, and the processor on the board is used for encrypting and decrypting data individually.

[0003] Currently, there are several approaches to achieving a secure data transmission system available on the market. Encryption file sharing is the process of encrypting data for transmission from one device to another. Several methods for encrypting data are used, including the advanced encryption standard (AES) for security and the secure hash algorithm used for hashing the transmission data and certification files. A password protection method to ensure secure file sharing has to start with a password to be accessed. The password protection method involves using a proximity-based communication interface to transfer a private key from the user's device. Secure file sharing platform to transmit the data privately to one or more user devices. The sharing platform allows files to be shared between different users or organisations within a protected mode to protect them from intruders and unauthorised users.

[0004] One-time passwords (OTP) are two forms of identification used in communication to access a system or service. It is a temporary password security code generated for the registered mobile number to access the confirmation for file sharing. Biometric authentication verifies the user's unique biological traits. The Biometric system stores this information in order to verify a user's identity when that user accesses their file sharing. Virtual private networks (VPN) are a secure way to access file sharing by encrypting the data being transferred between two or more parties over the internet. This type of encryption is designed to be highly secure and suitable for a variety of applications, including media streaming, VPN services, large file transfers, and block chain technologies. However, the existing secure data transmission system does not provide advanced cryptography techniques to enhance the level of security via authorised login, cryptographic key, one-time password through the web, or one-time password through mobile.

[0005] In the prior art, a system and method for sharing a plurality of files are disclosed. The system includes a file-sharing server, a network, and one or more user devices. Initially, the user granted permission based on another user's request to allow file sharing. The processor is a security implementation that allows the user to assign attributes to one or more files on the network. The user grants permission to assign file sharing and maintains control of the file even after the share is imitated. Further, the user can modify those usage permissions at any time after the share has been initiated. The network is transmitting the file from one device to one or more user devices, as in a public or private share.

[0006] The user can access the file only by logging directly into the system. If the private share is allowed to access the file sharing without an account to sign in. However, the system and method for sharing a plurality of files do not provide the passwords to allow the specific user to share files and to create free access for the user to the file sharing system. The system for sharing a plurality of files eliminates the level of protection for private sharing systems. The system does not require passwords or other types of file protection that are inconvenient and easier to defeat.

[0007] By addressing all the above-mentioned problems, there is a need for a system that implements secure file sharing through network communication, web development, and advanced cryptography techniques for greater security in file sharing. There is also a need for a system that enhances the level of security through OTP during file sharing. There is also a need for a system that implements three layers of network security during file sharing: authorised login, cryptographic key, one-time password (OTP) through the web, and one-time password (OTP) through mobile. There is also a need for a system where users get access only through an authorized person permits, even after the sign-in process. There is also a need for a system that uses hybrid encryption techniques for secure data transmission.
Objectives of the invention:
[0008] The primary objective of the invention is to provide a system that implements secure file sharing through network communication, web development, and advanced cryptography techniques for greater security in file sharing.

[0009] Another objective of the invention is to provide a system that provides a higher level of security, such as a one-time password (OTP) for public and private domains during file sharing.

[0010] The other objective of the invention is to provide a system that uses a third-party application for OTP generation and authentication through an authorised login process.

[0011] The other objective of the invention is to provide a system that gives every user individual access to upload and download files.

[0012] The other objective of the invention is to provide a system that uses secure file sharing for authorised individuals with file encryption and decryption along with a security environment.

[0013] Yet another objective of the invention is to provide a system that uses multi-level encryption techniques for secure data transmission.

[0014] Further objective of the invention is to provide a system that implements multiple layers of network security during file sharing via authorised login, cryptographic key, one-time password through the web, and one-time password through mobile.

[0047] In one example embodiment herein, a system 100 is created with different end users using one or more user devices 132. The system 100 comprises a finite number of users. All the users need to be connected through the network 126, i.e., single hotspot connectivity, using one or more user devices 132. The system 100 is carried out on the DJANGO platform. This system 100 can support file sharing in the public or private domain. The computing device 102 and the one or more user devices 132 are connected through the network 126, thereby communicating with an application server 128 through the network 126 for multi-layer secure file sharing using plurality of modules 110. The computing device 102 is used by the individual user for uploading the files in the database 130 through the application server 128. The one or more user devices 132 are used by the users for accessing and downloading the uploaded files in the database 130 through the application server 128.

The DJANGO platform is used for web development and design. After signing in, users get access only when the authorized person permits it through the authentication module 116. The user authentication feature is an in-built function of the DJANGO platform.

[0050] In one embodiment herein, the registered users can now share files in the public and private domains without any encryption process. One-to-one file sharing is involved in the private domain, where more security is needed, so encryption is applied through the encryption module 118. In the encryption process, after generating a cryptographic mask over the data using the AES algorithm and a robust private key generation with the SHA256 algorithm for authentication in the decryption module 124, the private key is shared between the two users.

[0051] In one embodiment herein, the verification module 122 incorporates another level of security with encrypted and unencrypted files through the OTP generation during file access. This OTP is shared on two platforms one is through the web and the mobile network. Unique OTPs are produced for each network. This OTP generation process is supported by python libraries like SMTP for email-based OTP and third-party apps like FAST2SMS for mobile based OTP. Another feature is that only the owner can edit the files whenever the need arises. The edit option is denied for other users in both public and private domains.

[0052] In one embodiment herein, the file sharing in both the public and private domains having eight cases. In the eight cases, one belongs to the public domain, and the remaining seven belong to the private domain. The public domain file is visible to all the users registered on a particular network 126, and every user has read-only access to the file. Whereas in the private domain, authentication is verified through a cryptographic key and a one-time password.

[0053] In one example embodiment herein, the first case relates to the public domain. In the first case, the files are uploaded and viewed by any of the registered users. The mobile number and email are not linked in the uploading data with the file sharing process. The files are displayed in the upload panel, which provides editing options to the uploaded user. The files are available for all registered users on the home page of the application. Since no OTP is linked, the files are downloaded readily by clicking the download file option.

[0054] In one example embodiment herein, the second, third and fourth cases are related to the private domain. In the second, third and fourth cases, the files are uploaded without encryption. In the second, third and fourth cases, the files are uploaded and viewed by only authorised users. While uploading the files, the user enters the uploaded data in the uploading widget 120. In the second case, the uploaded data is linked with the mobile number. The uploaded data is linked with the email in the third case. The uploaded data is linked with the both mobile number and email in the fourth case. The files are visible to all the registered users on the home page of the application. Whenever any user tries to download the file, the OTP will be sent to the linked mobile number in the second case. In the third case, the OTP will be sent by email. In the fourth case, the OTP will be sent to both the mobile number and email. Now the user enters the received OTP. If the entered OTP is correct, which is verified by the verification module 122, then the page is redirected to the download page. The user clicks the download option, and the file is downloaded.

[0055] In one example embodiment herein, the fifth case relates to the private domain. In the fifth case, the files are encrypted before uploading without any OTP authentication. The file is encrypted in the encrypted page of the encryption module 118 by generating a cryptographic mask over the data using the AES algorithm and robust private key generation with the SHA256 algorithm for authentication in the decryption module 124. The encrypted files are uploaded directly without any OTP authentication process. The encrypted files can be downloaded and viewed by any registered user. The encrypted files are decrypted in the decryption module 124 using a private key password, and the original files are accessible to the users.

[0056] In one example embodiment herein, the sixth, seventh and eighth cases are related to the private domain. In the sixth, seventh and eighth cases, the files are uploaded and viewed with encryption and an OTP authentication process. In the sixth, seventh and eighth cases, the files are encrypted on the encrypted page of the encryption module 118 by generating a cryptographic mask over the data using the AES algorithm. The robust private key generation with the SHA256 algorithm for authentication is part of the decryption module 124. In the sixth, seventh and eighth cases, the files are uploaded and viewed by only authorised users. The encrypted files are uploaded with the OTP authentication process. While uploading the encrypted files, the user enters the uploaded data in the uploading widget 120. The uploaded data is linked with the mobile number in the sixth case. The uploaded data is linked with the email in the seventh case. The uploaded data is linked with the both mobile number and email in the eighth case. Now the user enters the received OTP. If the entered OTP is correct, which is verified by the verification module 122, then the page is redirected to the download page. The user clicks the download option, and then the encrypted files are downloaded. The encrypted files can be downloaded and viewed by any registered user. The encrypted files are decrypted in the decryption module 124 using a private key password, and the original files are accessible to the users.

[0057] According to another exemplary embodiment of the invention, FIG. 4 refers to an example flowchart 400 of a method for multi-layer secure file sharing using a system 100.
