Abstract
Abstract @ An IC card comprises CPU (33), PROM (34) for storing programs, and RAM (35) for storing the results of arithmetic operations. PROM (34) stores a table on which the names of specific programs are registered. RAM (35) has execution counters which counts up each time each program is run so that the number of times the specific program is run is memorized. Prior to the running of each program by CPU (33), it is judged whether or not the program is a specific one. If it is the specific program, the execution counter counts up. When the count value of the execution counter is above a predetermined value, the running of the specific program is prevented.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
64 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; and means for judging whether or not a program to be run by said arithmetic operation means is a specific program, for counting the number of times the specific program is run, and for preventing the specific program from being run over predetermined times.
Claim 2
Dependent Claim
64 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; and means for judging whether or not a program to be run by said arithmetic operation means is a specific program, for counting the number of times the specific program is run, and for preventing the specific program from being run over predetermined times.
Claim 3
Dependent Claim
55 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; and means for judging whether or not a program to be run by said arithmetic operation means is a specific program and for running a preset delay time program when the specific program is run.
Claim 4
Dependent Claim
55 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; and means for judging whether or not a program to be run by said arithmetic operation means is a specific program and for running a preset delay time program when the specific program is run.
Claim 5
Dependent Claim
51 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; and means for judging whether or not a program to be run by said arithmetic operation means is a specific program and for preventing the continuous running of the specific program.
Claim 6
Dependent Claim
51 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; and means for judging whether or not a program to be run by said arithmetic operation means is a specific program and for preventing the continuous running of the specific program.
Claim 7
Independent Claim
28 words
The device according to any one of claims 1 to 3, characterized in that said memory means and said arithmetic operation means are constituted by semiconductor integrated circuits.
Claim 8
Dependent Claim
64 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; order memorizing means for memorizing the execution order of the programs; and means for preventing a program from being run by said arithmetic operation means, when the order of running this program does not coincide with the order memorized in said order memorizing means.
Claim 9
Dependent Claim
64 words
A data processing device comprising: memory means for memorizing data and programs; arithmetic operation means for running the memorized programs; order memorizing means for memorizing the execution order of the programs; and means for preventing a program from being run by said arithmetic operation means, when the order of running this program does not coincide with the order memorized in said order memorizing means.
Claim 10
Dependent Claim
23 words
The device according to claim 5, characterized in that said memory means and said arithmetic operation means are constituted by semiconductor integrated circuits.
