[ detailed description ] embodiments

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, interfaces, techniques, etc., in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

The following description is made with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a flowchart illustrating a first embodiment of a memory card authentication method for a mobile terminal according to the present invention.

And step S100, the mobile terminal detects the identification information of the memory card connected with the mobile terminal to obtain the calibrated memory capacity of the memory card.

It should be noted that the mobile terminal memory card authentication method provided by the present invention is premised on that the memory card can be correctly loaded, and if the memory card cannot be successfully loaded, that is, the mobile terminal cannot identify the memory card, the authentication method of the embodiment of the present invention is not involved. Therefore, a step of detecting that the memory card is inserted by the mobile terminal is generally included before step S100. It should be noted that the mobile terminal in the embodiments of the present invention is preferably a portable device such as a mobile phone and a tablet computer, so that the memory card can be identified conveniently and timely.

In step S100, after the memory card is identified and loaded, identification information (cardidentity) detection needs to be performed on the identified memory card, and during the identification information detection, information such as a manufacturer, a model, and a calibrated storage capacity of the memory card can be identified through a binary identification code of the memory card, where the binary identification code of the memory card is unique to each memory card and is different from binary codes of other memory cards. The nominal storage capacity is the memory capacity marked by the memory card, for example, when the manufacturer marks the memory capacity of the memory card as 8G through the binary identification code, the nominal storage capacity of the memory card is 8G. However, the nominal storage capacity may be the real memory capacity of the memory card, and the real memory capacity of the memory card may also be smaller than or far smaller than the nominal storage capacity.

Step S110, the mobile terminal fills a predetermined amount of data into the memory card, and determines whether a predetermined condition is satisfied between the predetermined amount and a calibrated storage capacity of the memory card.

In step S110, the method for filling the memory card with the predetermined amount of data by the mobile terminal may adopt two ways, one is to fill the memory card with the predetermined proportion of data, and the other is to fill the memory card with the predetermined unit amount of data. The difference between the two data filling modes will be described in detail in the following embodiments.

The step of determining whether the predetermined amount of data filled in the memory card and the nominal storage capacity of the memory card satisfy the predetermined condition may be: and judging whether the data filled into the memory card in the preset quantity reaches the quantity of a certain percentage of the nominal storage capacity of the memory card.

Step S120, when the predetermined condition is satisfied, it is determined that the calibrated storage capacity of the memory card is correct.

In step S120, when it is determined that the predetermined condition is satisfied, for example, when it is determined that the predetermined amount of data filled into the memory card reaches 95% of the nominal storage capacity of the memory card, it can be determined that the nominal storage capacity of the memory card is correct. Certainly, the user can set the determination criteria for the percentage of the nominal storage capacity of different memory cards by himself, which may be 90%, 99%, or 80% of the nominal storage capacity of the memory card. And is not particularly limited herein.

Of course, after the capacity of the memory card is detected in the data filling manner, the data filled in the memory card needs to be removed to ensure that the identified memory card is a clean empty card.

In the method for authenticating the memory card of the mobile terminal in the embodiment, the calibration storage capacity of the memory card is obtained by detecting the identification information of the memory card, then the predetermined amount of data is filled into the memory card, and whether the calibration storage capacity of the memory card is correct or not is determined by judging whether the predetermined amount of data filled into the memory card and the calibration storage capacity of the memory card meet the predetermined condition, so that the memory card can be authenticated by using the mobile terminal conveniently, quickly and accurately.

Referring to fig. 2, fig. 2 is a flowchart illustrating a second embodiment of a memory card authentication method for a mobile terminal according to the present invention.

In step S201, the mobile terminal detects identification information of the memory card connected thereto to obtain a calibrated storage capacity of the memory card.

The identified memory card needs to be subjected to identification information detection, and information such as the manufacturer, the model, the calibrated storage capacity and the like of the memory card can be identified through the binary identity identification code of the memory card in the identification information detection process.

Step S202, the obtained identification information of the memory card is matched with the identification information of the memory card stored in the mobile terminal.

Step S203, determining whether the identification information of the memory card matches the identification information of the memory card stored in the mobile terminal. If so, the process proceeds to step S204, otherwise, the process proceeds to step S205.

In steps S202 and S203, after the identification information of the memory card obtained by the mobile terminal, the identification information is matched with the identification information of the memory card stored in the mobile terminal, where the identification information of the memory card stored in the mobile terminal is generally data obtained and stored by the mobile terminal in the process of detecting the memory card, and when the mobile terminal identifies that the memory card is detected for the second time in the process of judging the matching result, the following steps are performed: if the identification information of the memory card is recorded in the mobile terminal, the next step is performed.

Step S204, the matched memory card identification information is notified to the user. Then, the flow ends.

At the moment, the mobile terminal reminds the user that the information of the memory card exists in the historical retrieval result of the mobile terminal, and meanwhile, the historical retrieval record information aiming at the identification information of the memory card is presented to the user to remind the user whether to detect again, when the user chooses not to detect again, the prompt is not carried out, the user can normally use the mobile phone, and meanwhile, the identification process of the memory card is stopped.

Step S205, the memory card is filled with data of a preset proportion of the nominal memory capacity of the memory card.

In step S205, the memory card is filled with data according to the nominal storage capacity corresponding to the detected memory card identification information, for example, if the nominal storage capacity corresponding to the detected memory card identification information is 8GB, the memory card is first filled with data of a predetermined proportion of the nominal storage capacity at a time, which may be 50% of the nominal storage capacity 8GB, that is, data of 4GB at a time.

In step S206, it is determined whether the storage space of the memory card has a remaining capacity. If the storage space of the memory card is judged to have the remaining capacity, the process proceeds to step S207, and if the storage space of the memory card is judged to have no remaining capacity, the process proceeds to step S208.

Step S207, the memory card is continuously filled with data of a predetermined proportion of the remaining capacity.

In this step, the data of the predetermined ratio of the remaining capacity may be the same as or different from the predetermined ratio in the previous step, and similarly, the predetermined ratio data may be specifically set according to the arithmetic capability of the mobile terminal, the size of the memory capacity of the memory card calibration, and the like. After the filling is completed once, the process returns to step S206 to continue to determine whether the memory card has a storage space left, and the process loops between steps S207 and S206 until step S206 determines that the storage space of the memory card has no remaining capacity.

In step S208, it is determined whether the amount of data filled into the memory card is the same as a predetermined amount. If so, the process proceeds to step S209, otherwise, the process proceeds to step S214.

In step S208, the total amount of data of the data filled into the memory card through steps S205, 207 is determined, and it is judged whether the total amount of data is the same as the predetermined amount. The predetermined number may be 95% of the calibrated storage capacity of the memory card, and certainly, the user may set a determination criterion for percentage of the calibrated storage capacity of different memory cards by himself, specifically 90%, 99%, or 80% of the calibrated storage capacity of the memory card. And is not limited herein. When it is judged that the amount of data filled into the memory card is the same as the predetermined amount, the flow proceeds to step S209.

In step S209, it is determined that the actual storage capacity of the memory card is correct.

In step S209, the user may be prompted that the actual storage capacity of the authenticated memory card is correct, and the manner of prompting the user that the data capacity of the memory card is correct may be displaying a prompt box, emitting voice or vibrating, and the like.

In step S210, the data filled in the memory card is cleared.

In step S211, the actual read/write speed of the memory card is obtained.

In step S211, the actual read/write speed of the memory card may be obtained by filling a larger unit of data into the memory card, and then obtaining the actual read/write speed of the memory card during the process of filling the data.

Step S212, the actual read-write speed information is notified to the user or the calibrated read-write speed information corresponding to the memory card identification information is inquired through the network, so as to determine the detection and comparison result of the memory card read-write speed.

In step S212, the mobile terminal notifies the user of the acquired actual read/write speed information of the memory card, where the notification may be displayed on a display screen through a prompt message, or prompted through voice. In addition, the mobile terminal can also inquire the calibrated read-write speed of the memory card on an official website of a manufacturer corresponding to the identification information of the memory card through a network, and then compare the calibrated read-write speed with the obtained actual read-write speed to obtain a comparison result, so that whether the actual read-write speed of the memory card meets the requirement or not can be clearly known through the comparison result.

In step S213, the actual read/write speed and the actual storage capacity information of the memory card are recorded in the mobile terminal. Then, the flow ends.

The mobile terminal itself includes a storage device, and actual read-write speed including a memory card and actual storage capacity information and the like can be recorded in the mobile terminal.

Step S214, determining the actual storage capacity of the memory card according to the amount of data filled into the memory card, and notifying the user of the actual storage capacity information of the memory card. Then, the process returns to step S210.

In step S214, the user is notified of the actual storage capacity information of the memory card to remind the user that the storage capacity of the memory card is not qualified. Similarly, the notification mode may be that the information is displayed on a display screen by a prompt, or the prompt is made by voice.

In the mobile terminal memory card identification method in the embodiment, the memory card is filled by filling the data in the preset proportion every time, so that the capacity of the memory card can be quickly and accurately detected; the identified memory card identification information is matched with the information stored in the mobile terminal before the process of identifying the memory capacity, so that the repeated identification of the same memory card can be prevented, and meanwhile, the identification method can also identify the read-write speed information of the memory card.

Referring to fig. 3, fig. 3 is a flowchart illustrating a memory card authentication method for a mobile terminal according to a third embodiment of the present invention.

In step S301, the mobile terminal detects identification information of the memory card connected thereto to obtain a calibrated storage capacity of the memory card.

Step S303, determining whether the identification information of the memory card matches the identification information of the memory card stored in the mobile terminal. If so, the process proceeds to step S304, otherwise, the process proceeds to step S305.

In steps S302 and S303, after the identification information of the memory card obtained by the mobile terminal is obtained, the identification information is matched with the identification information of the memory card stored in the mobile terminal, where the identification information of the memory card stored in the mobile terminal is generally data obtained and stored by the mobile terminal in the process of detecting the memory card, and when the mobile terminal identifies that the memory card is detected for the second time in the process of determining the matching result, the following steps are performed: if the identification information of the memory card is recorded in the mobile terminal, the next step is performed.

In step S304, the user is notified of the matching memory card identification information. Then, the flow ends.

In step S305, the memory card is continuously filled with data in a predetermined unit until the memory card is filled.

In step S305, the memory card is continuously filled with data in a predetermined unit, wherein the predetermined unit of data may be 1M, i.e., 1M at a time. The predetermined unit is not limited to 1M, and may be set according to factors such as the computing capability of the mobile terminal, and may be 2M, 3M, 10M, and the like, which are not listed here.

In step S306, it is determined whether the amount of data filled into the memory card is the same as a predetermined amount.

In step S306, the predetermined number may be 95% of the nominal storage capacity of the memory card, and of course, the user may set the determination criteria for percentage of the nominal storage capacity of different memory cards by himself, specifically, 90%, 99%, or 80% of the nominal storage capacity of the memory card. And is not limited herein. When it is judged that the amount of data filled into the memory card is the same as the predetermined amount, the flow proceeds to step S307.

In step S307, it is determined that the actual storage capacity of the memory card is correct.

In the mobile terminal in this embodiment, the identification information detection module detects the identification information of the memory card to obtain the calibrated storage capacity of the memory card, the data filling module fills the memory card with a predetermined amount of data, and the determination module determines that the predetermined amount of data filled into the memory card and the calibrated storage capacity of the memory card satisfy a predetermined condition to determine the actual storage capacity of the memory card.

Referring to fig. 5, fig. 5 is a schematic block diagram of a second embodiment of a mobile terminal 500 according to the present invention, which includes but is not limited to the following modules: the system comprises an identification information detection module 501, a data filling module 502, a judgment module 503, a notification module 504, a matching module 505, an acquisition module 506, a query module 507, a comparison module 508, a data clearing module 509 and a data recording module 510.

Specifically, the identification information detection module 501 is configured to detect identification information of a memory card accessing the mobile terminal to obtain a nominal storage capacity of the memory card. When detecting identification information (cardidentity) of the identified memory card, the identification information detection module 501 may identify information such as a manufacturer, a model, and a calibrated storage capacity of the memory card through a binary id of the memory card, where the binary id of the memory card is unique to each memory card to distinguish binary codes different from those of other memory cards. The nominal storage capacity is the memory capacity marked by the memory card, for example, when the manufacturer marks the memory capacity of the memory card as 8G through the binary identification code, the nominal storage capacity of the memory card is 8G. However, the nominal storage capacity may be the real memory capacity of the memory card, and the real memory capacity of the memory card may also be smaller than or far smaller than the nominal storage capacity.

The matching module 505 is configured to match the obtained identification information of the memory card with the identification information of the memory card already stored in the mobile terminal, and the determining module 503 determines whether the identification information of the memory card matches with the identification information of the memory card already stored in the mobile terminal. After the identification information of the memory card is obtained by the identification information detection module 501, the matching module 505 matches the identification information with the identification information of the memory card stored in the mobile terminal, where the identification information of the memory card stored in the mobile terminal is generally data obtained and stored by the mobile terminal in the process of detecting the memory card, and when the judgment module 503 judges that the memory card is detected for the second time in the process of judging the matching result, the method is as follows: if there is a record of the identification information of the memory card in the mobile terminal, the notification module 504 notifies the user of the matching identification information of the memory card. At this time, the notification module 504 may alert the user that the information of the memory card already exists in the history search result of the mobile terminal. Meanwhile, history retrieval record information aiming at the identification information of the memory card is presented to the user to remind the user whether to detect again, when the user selects not to detect again, the prompt is not carried out, the user can use the mobile phone normally, and the identification process of the memory card is stopped.

The data filling module 502 is used to fill the memory card with data of a predetermined proportion of the nominal memory capacity of the memory card. For example, if the nominal storage capacity corresponding to the detected identification information of the memory card is 8GB, the data filling module 502 fills the memory card with data at a predetermined ratio of the nominal storage capacity, which may be 50% of the nominal storage capacity 8GB, that is, 4GB of the nominal storage capacity at a time, first of all, and of course, the data at the predetermined ratio is not limited in this embodiment, and may be set according to the computing capability of the mobile terminal, the size of the nominal storage capacity of the memory card, and the like, which may be 30%, 60%, and the like, and this is not listed here.

In the first aspect, the determining module 503 determines whether the memory card has a remaining memory space, if so, the data filling module 502 continues to fill the data with the predetermined proportion of the remaining capacity of the memory card, and if the determining module 503 determines that no memory space remains, the data filling module continues to determine whether the amount of the data filled into the memory card is the same as the predetermined amount. The predetermined number may be 95% of the nominal storage capacity of the memory card, and certainly, the user may set the determination criteria of percentage of the nominal storage capacity of different memory cards by himself, specifically, 90%, 99%, or 80% of the nominal storage capacity of the memory card. And is not limited herein.

On the other hand, the data filling module 502 may also continuously fill the memory card with data in a predetermined unit, wherein the predetermined unit of data may be 1M, i.e., filling with data in a predetermined unit of 1M at a time. The predetermined unit is not limited to 1M, and may be set according to the computing capability of the mobile terminal, and may be 2M, 3M, 10M, and the like. When the memory card is full, the determination module 503 determines whether the amount of data filled into the memory card is the same as a predetermined amount.

The obtaining module 506 is configured to obtain an actual read/write speed of the memory card, where the obtaining module 506 obtains the actual read/write speed of the memory card by filling a larger unit of data into the memory card through the data filling module 502, and then obtains the actual read/write speed of the memory card in a process of filling the data.

The query module 507 is configured to query, through a network, the calibrated read-write speed information corresponding to the identification information of the memory card, and specifically, the query module 507 may query, through the network, the calibrated read-write speed corresponding to the memory card on an official website of a manufacturer corresponding to the identification information of the memory card.

The comparing module 508 is configured to compare the calibrated read-write speed queried by the querying module 507 with the actual read-write speed obtained by the obtaining module 506, so as to obtain a comparison result, and clearly obtain whether the actual read-write speed of the memory card meets the requirement through the comparison result.

The notifying module 504 is further configured to notify the user of the actual storage capacity and the actual read/write speed of the authenticated memory card, and notify the user of whether the memory card meets the requirements and the detection result. The notification mode of the notification module 504 may be that the notification information is displayed on a display screen, or that the notification information is prompted by voice, vibration, or the like.

The data clearing module 509 is configured to clear data filled in the memory card during the capacity and read/write speed detection process, so as to ensure that the authenticated memory card is empty. The data recording module 510 is configured to record identification information of the memory card in the mobile terminal, where the identification information includes a name of the memory card and information such as an actual storage capacity and an actual read/write speed after authentication corresponding to the name of the memory card.

In the mobile terminal in the embodiment, the data filling module is used for filling the memory card with the data in the preset unit and the data in the preset proportion respectively, so that the capacity of the memory card can be quickly and accurately checked; the identified memory card identification information is matched with the information stored in the mobile terminal before the process of identifying the memory capacity, so that the repeated identification of the same memory card can be prevented; and can also distinguish the read-write speed information of the memory card.
