Increasing concerns about security and privacy have raised the bar for interest in ways to protect information. Although newer approaches include face recognition, the use of passwords is commonly used today as the best approach for protecting data. Web sites, software programs, financial institutions universities, and many commercial stores are requiring that a password include the following attributes: consist of a fixed number of characters, include numbers and letters, special characters and lower and upper case letters. In addition, repetition of a password is not allowed, i.e. the updated password must be original to the user.
