摘要： Illustrative embodiments provide a computer implemented method, a data processing system, and a computer program product for previous password based authentication. In one illustrative embodiment, the computer implemented method comprises obtaining a combination of an identifier and a password and determining whether the password is current and correct. The computer implemented method responsive to determining the password is other than current and correct, prompting for an old password and determining whether the old password matches a previous password. Responsive to the old password matching a previous password, thereby creating a password match, permitting access to a resource.

摘要： Password aging based on the strength of the password provides an incentive for users to generate and/or memorize more complex passwords. The strength of the password is computed from a formula that relates the length of the password and the types of characters contained in the password to a strength value, which can be performed using a lookup table having values for different characteristics of the password, determining partial strength values corresponding to the ranges in which the characteristics fall, and then adding the partial strength values. Alternatively, a separate password strength application may be used to provide the strength value, which is entered by the user or administrator generating a new password. Alternatively, the password may be generated based on a specified desired expiration period, with the strength computation performed to ensure that the strength is sufficient to merit the desired expiration period.

摘要： Methods, apparatus and computer program products implement embodiments of the present invention that include receiving a storage command from a host computer to retrieve first data from a specific physical region of a storage device, and responsively retrieving second data from one or more additional physical regions of the storage device based on a logical mapping managed by the host computer. The second data is conveyed to a cache. In some embodiments, the logical mapping is received from the host computer prior to receiving the storage command. In alternative embodiments, the logical mapping is retrieved from the storage device prior to receiving the storage command.
