Abstract
Abstract A data processing method and apparatus have a resume function and use a password. When a power switch of a data processing system is turned on while it is selected that the resume function is to be enabled and the password is to be collated, the data processing system displays a message prompting an operator to input a password. When a predetermined password is input from a keyboard or the like, the data processing system executes resume processing, i.e., executes data processing subsequent to the data processing being executed immediately before the power switch was turned off. When the predetermined password is not input, the resume operation is inhibited, and a content saved by the resume function can be prevented from being disclosed to or destroyed by a third party.

Claim 6
Dependent Claim
45 words
A system according to claim 4, further comprising: means (4) for inhibiting said selection means to select disabling of the resume function and no collation of identification data until a coincidence of the identification data is detected after said switch means (11) is turned on.
Claim 7
Dependent Claim
70 words
A system according to claim 4, further comprising: means (2, 4, 6, 8) for setting a flag indicating ON/OFF of the resume function; and means for setting a flag indicating whether or not identification data is to be collated, wherein said discrimination means (4) is operated when the flag indicating that the resume function is enabled and the flag indicating that the identification data is to be collated are set.
Claim 8
Dependent Claim
