摘要： A system comprises a basic-input-output-system (“BIOS”), a disk drive, and a security system configured to prevent unauthenticated access to the disk drive. For each of at least two users out of a plurality of users, the BIOS authenticates the user based on the user's token. The BIOS also accesses secured data based on the authentication, and provides the secured data to the security system without input from the user.

摘要： A computer network includes at least one client computer coupled to a server computer that dynamically changes a user's password each time the user logs on to the computer network. By changing the password during the log on process, network security is increased. The server computer includes a users databases that contains a password, a username (if desired) and a biometrics template value associated with each user registered to access the computer network. A biometrics sensing device, such as a fingerprint sensor, is connected to each client computer. The user attempts to log on the server by entering a username which is optional and activating the biometrics sensing device. Appropriate software and/or hardware in the client and server computers capture a sample from the biometrics sensing device and create a template value from the captured sample. The template value thus is representative of a bodily characteristic of the user who activated the biometrics sensing device in an attempt to log on to the server computer. The client computer then transmits the template value to the server which compares the template value received from the client computer with template values previously stored in the users database. If a match is found, the log on process completes. At some point during or after the log on process, the biometrics account manager changes the current password associated with the user to a new password and overwrites the previous password with the new password.
摘要翻译：计算机网络包括耦合到服务器计算机的至少一个客户端计算机，每当用户登录到计算机网络时动态地改变用户密码。通过在登录过程中更改密码，增加网络安全性。服务器计算机包括用户数据库，其中包含密码，用户名（如果需要）和与注册为访问计算机网络的每个用户相关联的生物特征模板值。诸如指纹传感器的生物测定感测装置连接到每个客户端计算机。用户尝试通过输入可选的用户名并激活生物识别感测设备来登录服务器。客户端和服务器计算机中的适当软件和/或硬件从生物识别感测设备捕获样本，并从捕获的样本创建模板值。因此，模板值代表在尝试登录到服务器计算机时激活生物识别感测装置的用户的身体特征。然后，客户端计算机将模板值发送到服务器，该服务器将从客户端计算机接收的模板值与先前存储在用户数据库中的模板值进行比较。如果找到匹配，则登录进程完成。在登录过程中或之后的某个时刻，生物特征帐户管理器将与用户相关联的当前密码更改为新密码，并使用新密码覆盖以前的密码。
