Reasons for developing BC Auth

Memorizing and recording both the login ID and password, and using a one-time password make the procedure for authentication complicated, which makes it less convenient. The more sites you log in to, the more expensive it will be to maintain and manage.

PC browsers store various IDs and passwords, so they are far from secure. In recent years, the problem of password leakage due to phishing scams that cannot be prevented by ordinary one-time passwords has been increasing.

As a solution to these issues, we have developed a convenient and high-security authentication system that enables one-touch login and does not store passwords at all times.

How does it work?
Bce Auss consists of a blockchain server and plugins. The user side downloads the BCE AUS plugin from the dedicated page of the financial institution. Start the plugin and register a new account. After creating an account, you can use BCE AOS to log in to a financial institution's site with a hashed one-time password. For the second and subsequent logins, you will not be required to enter your ID and password because you will be authenticated only with the one-time password you obtained.
What can I do about phishing scams?
Bce Auss can prevent phishing scams with strong blockchain and plugin security.
First, we are strengthening security by creating an environment where you can only log in to a specific device. When the user downloads the plugin, a unique ID will be automatically assigned. By downloading to the terminal, the financial institution can be identified as the terminal (browser) used by the user himself.
Second, financial institutions are strengthening security by specifying the domain of the URL where they can log in. If you do not specify the URL, BCE Auth login will not work. When you are prompted to enter your ID or password by being guided to a phishing site, you can immediately recognize that it is a scam.
Please tell me about the introduction method.
It can be installed with the following flow.

  1. We will install the source code for logging into BCE AOS on websites such as financial institutions and e-commerce.
  2. We will install a function to obtain one-time password data from the blockchain.
  3. Create a page for downloading plugins.
  4. Specify the URL for the user to log in (only for the desired company).
How much is the installation cost and operation cost?
Please contact us as it depends on the scale, number of users, number of required servers, etc.
Please tell me how to manage the server.
There are two ways to manage the server: each company providing WEB services (on-premise) and the cloud.
