Systems and methods of blockchain platform for intermediaries and passwordless login

Abstract

The systems and methods on a blockchain platform for one or more intermediaries for services including proxy re-encryption, independent audit, multiple-signatures based smart wallet associated with a smart contract and split-key authentication to achieve secure passwordless login. Proxy re-encryption by receiving a ciphertext from a first user with condition parameters that has been encrypted with a dynamically selected encryption algorithm. Audit service receiving an encrypted file from a user for storage on the blockchain platform; enforcing the security policy parameters for all access requests to the file on the blockchain platform; and optionally providing audit report of the encrypted file storage and access. A smart wallet with a group key using multiple signatures based on receipt of a threshold number of signatures. Split-key authentication by splitting the private key into two or more parts; and assigning the split private key part to two or more client devices.

AI Technical Summary

Benefits of technology

The present invention is related to systems and methods on a blockchain platform for one or more intermediaries. The technical effects of the patent text include: receiving a ciphertext from a user with condition parameters that has been encrypted with a dynamically selected encryption algorithm, receiving a re-encryption key for another user, identifying whether the ciphertext is valid, re-encrypting the ciphertext, and outputting the re-encrypted ciphertext only if the ciphertext is valid. The system and method for intermediaries do not have the ability to decrypt the received ciphertext. Additionally, the patent text describes a mechanism for enforcing security policies for stored encrypted files on the blockchain platform, and a system for authenticating clients without a password.

Problems solved by technology

There are no mechanisms known in the industry that allow flexible user control to proxy reencryption.

The current model of cloud storage is operated through centralized authorities, which makes such a system susceptible to single point failures and permanent loss of data.

When the service provided by the dApp is not directly from the dApp owner itself but from other third parties, it brings up additional challenges.

While there are policies in the industry that provide end-to-end user flexibility in securing content from authoring to distribution, none of them offer flexibility in a blockchain setup where there is no single entity on the cloud controlling access.

While most systems offer securing content, they may fall short of providing an independently verifiable audit capability.

In a world of increasing cyber crime and digital fraud, when something goes wrong, it requires a lot of time and effort to do digital forensic investigation.

In such a situation, the entity smart wallet authentication system is vulnerable if passwords are shared by two or more people.

Such a vulnerability could also exist for a smart wallet associated with a household that has two or more members with access privileges.

Some even prevent reusing the previous 10 passwords, making it extremely painful to employees.

While this improves the security, it imposes unnecessary burden on the employees.

There is no simple, seamless and effortless method to provide access without compromising on the level of security provided.
