Abstract

Display pagers often contain information which is proprietary to the pager users. This information could be financial data of a company, medical problem of a patient, or personal information such as phone numbers or addresses. Most pagers have a lock function, however, it only protects the locked messages from being inadvertently erased either by incoming messages or by the users. As a result, proprietary information could be read by unauthorized users if the pager is either lost or misplaced.

PASSWORD PROTECTION FOR DISPLAY PAGERS

by Patrick S. Kung

   Display pagers often contain information which is proprietary to the pager users. This information could be financial data of a company, medical problem of a patient, or personal information such as phone numbers or addresses. Most pagers have a lock function, however, it only protects the locked messages from being inadvertently erased either by incoming messages or by the users. As a result, proprietary information could be read by unauthorized users if the pager is either lost or misplaced.

   This problem could be solved by assigning a password as the "KEY" before the read key could be activated. The password will be set up as a code plug programmable option. A separate button will be designated as a "FUNCTION" or "PASSWORD SELECTION" button. In the password selection mode, another key will be served as a directional but- ton for moving the cursor back and forth. In a numeric pager, the password could be a random combination of "X" numeric digits; in an alphanumeric pager, the password could be a random combination of "Y" alphanumeric characters.

   Once the password protection option is enabled in the code plug and the customer has selected the password, the read function could only be activated if a right password is entered. Password could either be programmed by hard wntact via the data port, OTA programming, or by manual input into the pager.

The way of manually entering the password is as follows-

A). Numeric pager-

   Refer to fig. 1, the read button is used for reading the message, the directional button is used to scroll either the messages or the cursor if the pager is in the "entering or selecting password" mode. The function key is used to get in and get out of the "password programming" and "password entering" modes.

The icon "g " is used for enabling the "password programming mode". Other forms of icons could also be used in this application.

   Refer to fig. 3, pushing the function button or password selection button will activate a series of digits and also the icon as described above. A reversed video will be positioned at the leftist digit as the "HOME". Moving the cursor to the icon and pressing the function button enable the password programming sequence. Moving the cursor to the desired digit and pressing the function button will enter the password into the pager. This process should be repeated until all the digits of the password are entered. Selecting the icon again and pressing the function button will program the pas...
