Description
[technical field]
Relevant a kind of the locking and unlock method of the present invention is meant a kind of personal digital assistant locking and unlock method especially.
[background technology]
PDA is the abbreviation of Personal Digital Assistant, also is personal digital assistant.This handheld device has been concentrated calculating, phone, multiple functions such as fax and network.It not only can be used to managing personal information (as address list, plan etc.), the more important thing is and can surf the web that transmitting-receiving Email can send a fax, even can also be used as mobile phone and use.Particularly importantly, these functions can realize by wireless mode.PDA also can be applied to GPS (GPS) and realize navigation feature.Certainly, be not that any PDA possesses above all functions; Even possess, also may can not realize owing to lack corresponding service.But can predict multi-functional fusions such as the trend of PDA development is calculated exactly with trend, communicated by letter, network, storage, amusement, ecommerce.
Along with personal digital assistant application more and more widely, in our personal digital assistant, about shelves or some file, can utilize the mode of software to lock reaching secret purpose, but this method only can't be accomplished the antitheft and auto-lock function of whole personal digital assistant at the content in the personal digital assistant.Can be in order to allow thief or own undesirable people can't use oneself personal digital assistant, people to wish especially with whole personal digital assistant locking, and cannot be by the Uboot Image reflex original code of upgrading.
In view of this, be necessary to develop a kind of personal digital assistant locking and unlock method in fact, utilize this personal digital assistant locking and unlock method, can be with whole personal digital assistant locking, thief or own undesirable people can't use the personal digital assistant of oneself, and cannot be by the Uboot Image reflex original code of upgrading.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of personal digital assistant locking and unlock method, utilize this personal digital assistant locking and unlock method, can be with whole personal digital assistant locking, thief or own undesirable people can't use the personal digital assistant of oneself, and cannot be by the Uboot Image reflex original code of upgrading.
For reaching above-mentioned purpose, personal digital assistant locking method of the present invention, this method comprises the following steps: to press the button that locks; The exhalation Application Program Interface that locks; Setting code in the Application Program Interface that locks; Select to carry out and add lock function.
For this locking method, can also comprise that one revises cryptographic processes, this process comprises the following steps: to press the button that locks; The exhalation Application Program Interface that locks; In the Application Program Interface that locks, revise password.
Another purpose of the present invention is to provide a personal digital assistant unlock method, and this method comprises the following steps: start; Input password and verification judge whether correctly before entering Uboot; If the above-mentioned "Yes" that is judged as then enters system.
If above-mentioned steps: input password and verification judge whether correctly before entering Uboot; Its judged result is a "No", then enters step: enter dormant state, and finish this flow process.
If above-mentioned steps: input password and verification judge whether correctly before entering Uboot; Its judged result is a "No", also can enter the following step: judge whether to reach default input number of times; If the above-mentioned steps judged result is a "Yes", then enters dormant state, and finish this flow process.
If above-mentioned steps: judge whether to reach default input number of times; Its judged result is a "No", then enters step: input password and verification judge whether correctly before entering Uboot.
Compared to prior art, personal digital assistant locking of the present invention and unlock method, utilize this personal digital assistant locking and unlock method, can be with whole personal digital assistant locking, thief or own undesirable people can't use the personal digital assistant of oneself, and cannot be by the Uboot Image reflex original code of upgrading.
For purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 illustrates the process flow diagram of personal digital assistant unlock method of the present invention.
Fig. 2 illustrates the process flow diagram of personal digital assistant locking method of the present invention.
Fig. 3 illustrates the modification password process flow diagram of personal digital assistant locking method of the present invention.
[embodiment]
See also shown in Figure 2ly, it illustrates the process flow diagram into personal digital assistant locking method of the present invention.
Personal digital assistant locking method of the present invention, this method comprises the following steps: to press the button (step 201) that locks; The exhalation Application Program Interface (step 202) that locks; Setting code (step 203) in the Application Program Interface that locks; Select to carry out and add lock function (step 204).
See also shown in Figure 3ly, it illustrates the modification password process flow diagram into personal digital assistant locking method of the present invention.
For this locking method, can also comprise that one revises cryptographic processes, this process comprises the following steps: to press the button (step 301) that locks; The exhalation Application Program Interface (step 302) that locks; In the Application Program Interface that locks, revise password (step 303).
This button circuit that locks only needs that this button is connected to level state of CPU GPIO and triggers and once interrupt get final product, about the position of the button that locks, can be placed on recesses or with the button multiplexing of panel.Recesses such as personal digital assistant support inner face are opened an aperture, use flexible material to cover it, dimpling.
For the above-mentioned Application Program Interface that locks, need enter setting code dialog box setting code for first use, and choose this function of execution in selecting to carry out the features dialog that locks.Need change password for later use, then need equally the Application Program Interface that locks of breathing out, just can revise password after can inputing password confirming earlier.
See also shown in Figure 1ly, it illustrates the process flow diagram into personal digital assistant unlock method of the present invention.
Another purpose of the present invention is to provide a personal digital assistant unlock method, and this method comprises the following steps: start (step 101); Input password and verification judge whether correctly (step 102) before entering Uboot; If the above-mentioned "Yes" that is judged as then enters system's (step 103).
If above-mentioned steps: input password and verification judge whether correctly (step 102) before entering Uboot; Its judged result is a "No", then enters step: enter dormant state (step 105), and finish this flow process.
If above-mentioned steps: input password and verification judge whether correctly (step 102) before entering Uboot; Its judged result is a "No", also can enter the following step: judge whether to reach default input number of times (step 104); If the above-mentioned steps judged result is a "Yes", then enters dormant state (step 105), and finish this flow process.
If above-mentioned steps: judge whether to reach default input number of times (step 104); Its judged result is a "No", then enters step: input password and verification judge whether correctly (step 102) before entering Uboot.
Wherein, the dormant state in the above steps can also can be deep sleep state for general dormant state, and this preset times can be 5 times.
Compared to prior art, personal digital assistant locking of the present invention and unlock method, utilize this personal digital assistant locking and unlock method, can be with whole personal digital assistant locking, thief or own undesirable people can't use the personal digital assistant of oneself, and cannot be by the Uboot Image reflex original code of upgrading.And if the user forgets Password, can arrive the method upgrading Image reflex original code of service point by JTAG.
