Byteseal is a password management system designed for computers and mobile devices. It eliminates the effort to remember the credentials to log in to any website or account. It stores the data or credentials on a private cloud network. Also, as data theft is increasingly becoming hard to tackle, Byteseal is not just restricted to software but also comprises hardware authentication. The device is compact, card-shaped, and portable that operates on the biometric ID system with the help of world’s most secure capacitive fingerprint sensor, enabling a smooth and hassle-free login process. The mix and merge of the software and device, subsequently, shapes up a unique combination of biometric system and credential manager; thus, adding additional security to your data and the login process. Privacy of your data matters the most when the world is moving fast towards automation and technology-driven innovation, leading to reshaping workplaces and the quality of our lives. In a similar attempt, Byteseal is an innovation towards improving the security of your data on the Internet; shielding it against the major cyber-attacks such as ‘stolen credentials’ while letting you reap the benefits of the internet without worrying about data theft due to web account break-ins. It is a card-shaped device that simplifies access to your online web accounts. What sets this device apart from setting up a secure way of managing passwords is its concept of tokenization. The device communicates with the software installed on your computer which manages your credentials. Furthermore, it exchanges the token of authentication without distorting or changing the credentials. The data consisting of credentials are safely stored on the private cloud network. Once the device authenticates the user, the credential for the respective website is granted access for login. Eventually, it is a merge of the biometric and credential management systems; thus, providing double authentication.
