Therefore, the security control module 140 can capture the encrypted voice EV through the memory transmission unit 150.

Referring to FIG. 5, a block diagram of the encrypted voice EV stored in the mobile communication device 100 of the network server 300 is shown. As shown in FIG. 5, the network server 300 can communicate with the mobile communication device 100 via the network transmission unit 160 and the Internet 900. Therefore, the security control module 140 can capture the encrypted voice EV through the network transmission unit 160.

In the flow of step S206 of FIG. 1, first, in step S207, the security control module 140 first determines whether the encrypted voice EV is stored in the memory 110 of the mobile communication device 100. If the encrypted voice EV is stored in the memory 110, step S209 is performed; if the encrypted voice EV is not stored in the memory 110, step S211 is performed.

In step S209, the security module 140 directly retrieves the encrypted voice EV from the memory 110.

In step S211, the security control module 140 further determines whether the encrypted voice EV can be captured by the memory transmission unit 150 or the network transmission unit 160 of the mobile communication device 100. If the encrypted voice EV can be retrieved by the memory transmission unit 150, step S213 is performed; if the encrypted voice EV can be retrieved by the network transmission unit 160, step S215 is performed; if the encrypted voice EV cannot be used by the memory transmission unit 150 or the network When the transmission unit 160 retrieves, step S223 is performed.

In step S213, the security control module 140 directly retrieves the encrypted voice EV stored in the memory card 200 from the memory transfer unit 150.

In step S215, the security control module 140 directly retrieves the encrypted voice EV stored in the network server 300 by the network transmission unit 160.

In step S223, the security control module 140 prohibits starting the execution program P.

After performing step S209, step S213 or step S215, the security control module 140 has retrieved the encrypted speech EV corresponding to the execution program P, and then proceeds to step S217.

In step S217, the speech recognition unit 130 recognizes the decrypted speech DV as a decrypted character DW, and recognizes the encrypted speech EV as an encrypted text EW.

Next, in step S219, the security control module 140 determines whether the decrypted character DW is the same as the encrypted character EW. If the decrypted character DW is the same as the encrypted character EW, step S221 is performed; if the decrypted character DW is different from the encrypted character EW, step 222 and step S223 are executed.

In step S221, the security control module 140 directly starts the execution of the program P.

In step S222, the security control module 140 can be further controlled by the timer 180. The time T is taken, and the time T and the decrypted voice DV are transmitted to the network server 300. That is to say, when a thief wants to perform a booting process or open a specific file, under the protection of the decryption method of the embodiment, the thief can not only successfully boot or open a specific file, but also use the thief. The time and its voice are passed to the web server 300 for tracking by the police unit.

In step S223, the security control module 140 prohibits the execution of the execution program P.

Through the above embodiments, the mobile communication device 100 can set an encrypted voice EV for the booting procedure or any file opening procedure to ensure information security.

Second embodiment

Please refer to FIGS. 6A-6C for a flowchart of a method for decrypting the mobile communication device 100 according to the second embodiment of the present invention. The decryption method of this embodiment is different from the decryption method of the first embodiment in that the number of decryptions is more limited to further avoid the cracking method of the robot program, and the rest of the similarities are not repeated.

As shown in FIG. 6C, if the decrypted character DW is different from the encrypted character EW after step S219, the process proceeds to step S225 instead of directly proceeding to step S222 and step S223.

In step S225, it is determined whether the number of executions of step S219 is greater than a predetermined number of times (for example, three times). If the number of executions of step S219 is not greater than the predetermined number of times, step S205 is repeatedly performed; if the number of executions of step S219 is greater than the predetermined number of times, step S227 is performed.

In step S227, the decryption method of the execution program P is prohibited from being executed. Go to step S222 and step S223.

Wherein, before step 205, the step S229 is updated. In step S229, it is judged whether or not the decryption method of the execution program P has been prohibited. If the decryption method of the execution program P has been disabled, step S222 and step S223 are performed; if the decryption method of the execution program P is not prohibited, step S205 is performed.

That is to say, the decryption method of the embodiment only allows the user to try within the number of executions. If the number of executions is exceeded, the execution program P is immediately locked, and steps S205, S206, S217, S279, and steps cannot be performed. S221. This makes the robot program unable to crack the encryption smoothly.

Third, through the comparison of encrypted speech and decrypted speech, the user does not need to input any text, which is quite convenient to use.

Fourth, when the user does not forget to decrypt the voice, the security control module can also control the display unit to display a decryption prompt information. The user can retrieve the correct decrypted speech by decrypting the prompt information, or obtain the correct decrypted speech by answering the decryption prompt information, which is quite ergonomic.

Fifth, when a thief wants to perform a booting process or open a specific file, under the protection of the decryption method of the embodiment, the thief can not only successfully boot or open a specific file, but also use the thief to use the time. And its voice is passed to the web server for tracking by the police unit.

Sixth, the number of decryptions can be limited to a predetermined number of times to further avoid the cracking method of the robot program.
