1. A computer with a password processing function, comprising:
- input means for inputting a first password and a second password;
first conversion means for converting the first password inputted from the input means into a first compressed bit row in accordance with a predetermined rule;
storage means for storing the first compressed bit row converted by the first conversion means;
second conversion means for converting the second password inputted from the input means into a second compressed bit row in accordance with the same predetermined rule of the first conversion means;
comparison means for comparing the second compressed bit row converted by the second conversion means with the first compressed bit row stored in the storage means; and
setting means for, when as a result of the comparison by the comparison means the second compressed bit row coincides with the first compressed bit row, setting the computer to an access allowable state.

Abstract
A computer has a conversion module for converting a password to be registered into a compressed-bit row in accordance with a predetermined rule. A registration module stores the compressed bit row of the registered password in a backup RAM. A conversion module converts a password to be compared with the registered password into a compressed bit row. A comparison module compares the compressed bit row of the compared password with the compressed bit row of the registered password. Upon detecting a coincidence between the two compressed bit rows, a system activation module is activated to set the system to a access allowable state.
