Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication systems such as wired and wireless communication systems and satellite-based communication systems that transmit data via frames or packets.

A communication system in which a mobile terminal according to an embodiment of the present invention is operable will now be described with reference to fig. 2.

Such communication systems may use different air interfaces and/or physical layers. For example, the air interface used by the communication System includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and Universal Mobile Telecommunications System (UMTS) (in particular, Long Term Evolution (LTE)), global System for Mobile communications (GSM), and the like. By way of non-limiting example, the following description relates to a CDMA communication system, but such teachings are equally applicable to other types of systems.

Referring to fig. 2, the CDMA wireless communication system may include a plurality of Mobile terminals 100, a plurality of Base Stations (BSs) 270, a Base Station Controller (BSC) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the BS270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that a system as shown in fig. 2 may include multiple BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz, 5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a Base Transceiver Subsystem (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each partition of a particular BS270 may be referred to as a plurality of cell sites.

As shown in fig. 2, a Broadcast Transmitter (BT) 295 transmits a Broadcast signal to the mobile terminal 100 operating within the system. A broadcast receiving unit 111 as shown in fig. 1 is provided at the mobile terminal 100 to receive a broadcast signal transmitted by the BT 295. In fig. 2, several satellites 300 are shown, for example, GPS satellites 300 may be employed. The satellite 300 assists in locating at least one of the plurality of mobile terminals 100.

In fig. 2, a plurality of satellites 300 are depicted, but it is understood that useful positioning information may be obtained with any number of satellites. The location information unit 115 as shown in fig. 1 is generally configured to cooperate with the satellites 300 to obtain desired positioning information. Other techniques that can track the location of the mobile terminal may be used instead of or in addition to GPS tracking techniques. In addition, at least one GPS satellite 300 may selectively or additionally process satellite DMB transmission.

As a typical operation of the wireless communication system, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station is processed within a particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC275 provides call resource allocation and mobility management functions including coordination of soft handoff procedures between the BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC280 interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

The mobile communication unit 112 of the communication unit 110 in the mobile terminal accesses the mobile communication network based on the necessary data (including the user identification information and the authentication information) of the mobile communication network (such as the mobile communication network of 2G/3G/4G, etc.) built in the mobile terminal to transmit the mobile communication data (including the uplink mobile communication data and the downlink mobile communication data) for the services of web browsing, network multimedia playing, etc. of the mobile terminal user.

The wireless internet unit 113 of the communication unit 110 performs a function of a wireless hotspot by operating a related protocol function of the wireless hotspot, the wireless hotspot supports access by a plurality of mobile terminals (any mobile terminal other than the mobile terminal), transmits mobile communication data (including uplink mobile communication data and downlink mobile communication data) for mobile terminal user's web browsing, network multimedia playing and other services by multiplexing the mobile communication connection between the mobile communication unit 112 and the mobile communication network, since the mobile terminal essentially multiplexes the mobile communication connection between the mobile terminal and the communication network for transmitting mobile communication data, the traffic of mobile communication data consumed by the mobile terminal is charged to the communication tariff of the mobile terminal by a charging entity on the side of the communication network, thereby consuming the data traffic of the mobile communication data included in the communication tariff contracted for use by the mobile terminal.

Fig. 3 is a schematic diagram of hardware entities performing information interaction in the embodiment of the present invention, where fig. 3 includes: a terminal device 1 and a server 2. The terminal device 1 is composed of terminal devices 11-14, and the terminal devices perform information interaction with a server through a wired network or a wireless network. The terminal equipment comprises mobile phones, desktop computers, PC machines, all-in-one machines and the like.

After a key (such as a WIFI key) for WIFI information login authentication is obtained according to identification information (such as first identification information and second identification information) related to the first WIFI information, the obtained second WIFI information to be identified (the second WIFI information is a subset or all of the first WIFI information) is decrypted according to the key (such as the WIFI key), namely login authentication is broken, and the at least one second WIFI information to be identified is identified as target WIFI information. Specifically, as shown in fig. 3, the processing logic 10 of the terminal device includes: s1, triggering WIFI information identification according to the first operation acquired on the application interface to acquire at least one piece of first WIFI information; s2, analyzing the at least one piece of first WIFI information to obtain identification information formed by first identification information and second identification information related to the first WIFI information, and obtaining a first secret key according to the identification information; s3, encrypting the first key according to an encryption strategy to obtain an encryption result, wherein the encryption result is used for login authentication of WIFI information; s4, decrypting the encrypted result according to a decryption strategy corresponding to the encryption strategy so as to perform login authentication and decryption on the at least one second WIFI information to be identified, and identifying the at least one second WIFI information to be identified as target WIFI information; and S5, displaying the target WIFI information in the application interface, and performing WIFI networking processing according to a second operation acting on the target WIFI information. In the embodiment of the invention, the server only provides WIFI information to the terminal, all identification processing logics are irrelevant to the server, and a mode that the connection can be successfully carried out only by a password or authentication login is originally required is identified into a mode that the connection can be successfully carried out directly without the password or the authentication login through a local WIFI information identification mechanism of the terminal.

The above example of fig. 3 is only an example of a system architecture for implementing the embodiment of the present invention, and the embodiment of the present invention is not limited to the system architecture described in the above fig. 3, and various embodiments of the method of the present invention are proposed based on the system architecture described in the above fig. 3.

As shown in fig. 4, a WIFI information identification method according to an embodiment of the present invention includes: after the application is run, WIFI information identification is triggered according to a first operation acquired on an application interface, and at least one piece of first WIFI information (101) is acquired. The at least one first WIFI information here may be understood as all WIFI information that can be searched from nearby, including that the WIFI signal quality is good and the WIFI signal quality is poor. In an actual application, if the application is an application for WIFI identification or a management application integrated with a WIFI identification function, after WIFI information identification is triggered, all nearby searched WIFI information is scanned to obtain at least one piece of first WIFI information used for generating a subsequent first secret key. And analyzing the at least one piece of first WIFI information to obtain first identification information and second identification information (102). Here, the first identification information may be an SSID, and the second identification information may be a BSSID. SSID is an abbreviation of Service Set Identifier, referring to Service Set Identifier. The SSID technology can divide a wireless local area network into several sub-networks requiring different authentication, each sub-network requires independent authentication, and only users who pass authentication can enter the corresponding sub-network, so as to prevent unauthorized users from entering the network, for example, the CMCC is an SSID of china mobile. The BSSID is the Media Access Control (MAC) address of the router. And obtaining a first key (103) according to the first identification information and the second identification information. And when the first identification information is SSID and the second identification information is BSSID, obtaining Key according to the SSID and the BSSID, and taking the Key as a first Key. And encrypting the first secret key according to an encryption strategy to obtain an encryption result, wherein the encryption result is used for login authentication of WIFI information (104). In an actual application, after a known parameter value corresponding to a first Key is obtained through local inquiry of a terminal, the Key is used for encrypting the value, the encrypted value is used as a WIFI password, and the WIFI password is used for login authentication of WIFI information. Certainly, for many security considerations such as security, decompilation prevention, and the like, the encrypted Value may be further subjected to security enhancement, for example, the encrypted Value may be further subjected to encryption processing, that is, the encrypted Value is converted into a password for WiFi connection through an algorithm, and is encrypted by XXTea to obtain a final WiFi password. At least one second WIFI information to be identified and the encryption result are obtained (105). Here, the second WIFI information is a subset or all of the first WIFI information. And decrypting the encryption result according to a decryption strategy corresponding to the encryption strategy so as to perform login authentication and decryption on the at least one second WIFI information to be identified, identifying the at least one second WIFI information to be identified as target WIFI information, and displaying the target WIFI information in the application interface (106). Decrypting the obtained second WIFI information to be identified (the second WIFI information is a subset or all of the first WIFI information), and when the encryption strategy is as follows: after a known parameter value corresponding to a first Key is obtained through local inquiry of a terminal, the Key is used for encrypting the value, the encrypted value is used as a WIFI password, and the WIFI password is used for login authentication of WIFI information. The corresponding decryption policy is: the received encryption result is an encryption value, the encryption value is used as a WIFI password, in order to identify second WIFI information to be identified, which needs the password, as target WIFI information (free WIFI which does not need the password or does not need authentication login), the WIFI password is used for login authentication of the WIFI information, so that the encryption value used as the WIFI password is decrypted by using a Key corresponding to the value, login authentication cracking of the second WIFI information to be identified is realized, and the terminal user can use the WIFI information without the password or authentication login. And performing WIFI networking processing (107) according to a second operation acting on the target WIFI information.

By adopting the embodiment of the invention, networking is not needed, and the networking is necessary in the prior art; locally identifying whether the searched nearby WIFI is free WIFI or not at the terminal, and displaying the free WIFI for a user to select; in the prior art, the identification is carried out at a server and is only transmitted to a terminal side for display. Therefore, the embodiment of the invention does not need to network to request a background server when identifying the free WiFi, breaks through the limitation that the original identification of the free WiFi must depend on a data network (2G/3G/4G) or a WiFi network, thereby realizing the local identification of the free WiFi at the terminal without networking, and identifying the original mode that the connection can be successful only by needing a password or requiring authentication login into a mode that the connection can be successful directly without the password or requiring authentication login. The application scenarios of the embodiment of the invention comprise: and the free WiFi is identified in the state without the network, so that the user can select connection, and smooth switching from no network to the network is really realized. Except for the case of no network state, the method further comprises the following steps: under the scenes of 'weak network', even 'without sim card' and 'without data network', the free WiFi can be accessed to the Internet.

In one practical application, the operation of the user is received on an application for WIFI identification or a management application integrated with a WIFI identification function, a local "identification process" of the application is triggered to initiate identification, and the scanned nearby WIFI (SSID + BSSID) is transmitted to a local algorithm library. The local algorithm library converts the SSID and BSSID of the WiFi into a Key Value through an algorithm, transmits the Key Value into a local database, finds out the Value corresponding to the Key Value according to different matching rules (the Key and the Value are in one-to-one correspondence), encrypts the Value to obtain the encrypted Value and puts the encrypted Value into the local algorithm library. The local algorithm library converts the encrypted Value into a password for WiFi connection through an algorithm, further can be encrypted through XXTea and output to an 'identification process', and then the 'identification process' displays the WiFi as free WiFi according to the returned WiFi and the corresponding password; if no password is returned, no free WiFi is displayed. Identifying free WIFI at the terminal side, the method can be understood as storing encrypted authentication information locally, so that the WIFI can be decrypted locally by using the authentication information, namely, a WIFI password is broken, and the user side sees that: and entering the application, triggering and identifying, and directly presenting a free WIFI list for the user to select the target free WIFI with high WIFI quality from the free WIFI list. As shown in fig. 5, a schematic view of a user interface for finally obtaining free WIFI information is shown, in the user interface, a star-level reminder, one star, two stars, three stars, four stars, five stars, and the like, is provided behind a high-quality target free WIFI. The larger the number is, the higher the star level is, which indicates that the quality of the network signal provided by the corresponding target free WIFI is better.

The WIFI information identification method of the embodiment of the invention comprises the following steps: after the application is run, WIFI information identification is triggered according to a first operation acquired on the application interface, and at least one piece of first WIFI information is acquired. The at least one first WIFI information here may be understood as all WIFI information that can be searched from nearby, including that the WIFI signal quality is good and the WIFI signal quality is poor. In an actual application, if the application is an application for WIFI identification or a management application integrated with a WIFI identification function, after WIFI information identification is triggered, all nearby searched WIFI information is scanned to obtain at least one piece of first WIFI information used for generating a subsequent first secret key. And analyzing the at least one piece of first WIFI information to obtain first identification information and second identification information. Here, the first identification information may be an SSID, and the second identification information may be a BSSID. SSID is an abbreviation of Service Set Identifier, referring to Service Set Identifier. The SSID technology can divide a wireless local area network into several sub-networks requiring different authentication, each sub-network requires independent authentication, and only users who pass authentication can enter the corresponding sub-network, so as to prevent unauthorized users from entering the network, for example, the CMCC is an SSID of china mobile. The BSSID is the Media Access Control (MAC) address of the router. And obtaining a first key according to the first identification information and the second identification information. And when the first identification information is SSID and the second identification information is BSSID, obtaining Key according to the SSID and the BSSID, and taking the Key as a first Key.

And then, encrypting the first secret key according to an encryption strategy to obtain an encryption result, wherein the encryption result is used for login authentication of the WIFI information. Specifically, there are two implementation schemes: 1) and encrypting the first target parameter corresponding to the first key according to the first key to obtain the encrypted target parameter, converting the encrypted target parameter, and taking the obtained conversion result as the encryption result, wherein the encryption result is used for login authentication of the WIFI information. 2) And encrypting the first target parameter corresponding to the first key according to the first key to obtain the encryption result, wherein the encryption result is used for login authentication of the WIFI information. For the two specific implementation modes, in an actual application, after a known parameter value corresponding to the first Key is obtained through local inquiry from a terminal, the value is encrypted by using the Key, and the encrypted value is used as a WIFI password which is used for login authentication of WIFI information. Certainly, for many security considerations such as security, decompilation prevention, and the like, the encrypted Value may be further subjected to security enhancement, for example, the encrypted Value may be further subjected to encryption processing, that is, the encrypted Value is converted into a password for WiFi connection through an algorithm, and is encrypted by XXTea to obtain a final WiFi password. And acquiring at least one second WIFI information to be identified and the encryption result. Here, the second WIFI information is a subset or all of the first WIFI information. And decrypting the encryption result according to a decryption strategy corresponding to the encryption strategy so as to perform login authentication and decryption on the at least one second WIFI information to be identified, identifying the at least one second WIFI information to be identified as target WIFI information, and displaying the target WIFI information in the application interface. Decrypting the obtained second WIFI information to be identified (the second WIFI information is a subset or all of the first WIFI information), and when the encryption strategy is as follows: after a known parameter value corresponding to a first Key is obtained through local inquiry of a terminal, the Key is used for encrypting the value, the encrypted value is used as a WIFI password, and the WIFI password is used for login authentication of WIFI information. The corresponding decryption policy is: the received encryption result is an encryption value, the encryption value is used as a WIFI password, in order to identify second WIFI information to be identified, which needs the password, as target WIFI information (free WIFI which does not need the password or does not need authentication login), the WIFI password is used for login authentication of the WIFI information, so that the encryption value used as the WIFI password is decrypted by using a Key corresponding to the value, login authentication cracking of the second WIFI information to be identified is realized, and the terminal user can use the WIFI information without the password or authentication login. And carrying out WIFI networking processing according to a second operation acting on the target WIFI information.

In one practical application, the operation of the user is received on an application for WIFI identification or a management application integrated with a WIFI identification function, a local "identification process" of the application is triggered to initiate identification, and the scanned nearby WIFI (SSID + BSSID) is transmitted to a local algorithm library. Here, the local database is obtained in the following manner: the local algorithm library is resident locally, and the local algorithm libraries of different applications are the same. The local database is different according to the geographic location of the user of the application, for example, the "free WiFi local database" of the user in beijing city is only free WiFi in beijing city. Therefore, the space size of the local database is reduced, and the occupation of the mobile phone space of the user is reduced. The local database can be packaged together with the installation package when the installation package of the application is generated, or dynamically issues updates according to different geographic positions on the cloud server. And after the SSID and BSSID of the WiFi are converted into a Key Value through an algorithm in the local algorithm library, the Key Value is transmitted into the local database, the Value corresponding to the Key Value is found out by the local database according to different matching rules (Key and Value are in one-to-one correspondence), and the Value is encrypted to obtain encrypted Value and put into the local algorithm library. The local algorithm library converts the encrypted Value into a password for WiFi connection through an algorithm, further can be encrypted through XXTea and output to an 'identification process', and then the 'identification process' displays the WiFi as free WiFi according to the returned WiFi and the corresponding password; if no password is returned, no free WiFi is displayed. Identifying free WIFI at the terminal side, the method can be understood as storing encrypted authentication information locally, so that the WIFI can be decrypted locally by using the authentication information, namely, a WIFI password is broken, and the user side sees that: and entering the application, triggering and identifying, and directly presenting a free WIFI list for the user to select the target free WIFI with high WIFI quality from the free WIFI list. As shown in fig. 5, a schematic view of a user interface for finally obtaining free WIFI information is shown, in the user interface, a star-level reminder, one star, two stars, three stars, four stars, five stars, and the like, is provided behind a high-quality target free WIFI. The larger the number is, the higher the star level is, which indicates that the quality of the network signal provided by the corresponding target free WIFI is better.

Based on the foregoing embodiments, in the WIFI information identification method according to the embodiments of the present invention, the first key and the first target parameter are both at least one. Each first key may be set to: the first key and the first target parameter form a matching relationship pair, the matching relationship pair is at least one, and the length of each matching relationship pair is different. Specifically, different Key values correspond to different Value values, for example, Key1 corresponds to Value1, Key2 corresponds to Value2, and the like. Meanwhile, the lengths of the corresponding relations of different 'Key-Value' are different. Therefore, the risk that the local database is cracked by the 'explosion database' can be greatly reduced through single matching and different relation lengths, and decompiling and decompilation can be realized.

Here, it should be noted that: the above description related to the terminal and the server items is similar to the above description of the method, and the description of the beneficial effects of the same method is omitted for brevity. For technical details not disclosed in the embodiments of the terminal and the server of the present invention, please refer to the description of the embodiments of the method flow of the present invention.

The embodiment of the invention is explained by taking a practical application scene as an example as follows:

in an application scenario, for a scheme for identifying free WIFI, in the prior art, when identifying free WIFI, the application needs to be networked with a background server corresponding to the application, and uploads nearby WIFI scanned by a local application client to the background server for identification, and then sends down whether the WIFI is free WIFI and a corresponding connection password to the local application client, and the local application client displays the hit WIFI as free WIFI. Free WIFI is WIFI that can be freely connected provided through an application. In the application scene, the prior art is adopted, so that the WIFI information identification cannot be realized when the network state is not good or under the condition that a user cannot be networked currently.

For the application scenario, the embodiment of the invention is adopted, in brief, when other free WiFi is identified, a networking request background server is not needed any more, and the limitation that the original identification of the free WiFi must depend on a data network (2G/3G/4G) or a WiFi network is broken through, so that the identification of the free WiFi can be realized locally at a client. For the management application integrating the WIFI identification function, the scheme of this embodiment is applied to the management application, and when entering the management application to perform the identification operation, the free WIFI can be identified without networking, as shown in fig. 5. After the free WiFi is identified, the free WiFi in the column of 'safe free Internet surfing' can be clicked for connection.

For the application scenario, as shown in fig. 7, a specific process adopting the embodiment of the present invention includes:

step 301, according to the operation of the user, initiating identification in an "identification process" local to the application client at the terminal side, and transmitting the scanned nearby WiFi (ssid + bssid) into a "local algorithm library". Here, the "local algorithm library" is resident locally, and the "local algorithm libraries" of different application clients are all the same. The local database is different according to the geographic location of the user of the application client, for example, the free WiFi local database of the user in beijing city is only free WiFi in beijing city.

Step 302, the "local algorithm library" transforms the ssid and bssid of WiFi into a KEY value through algorithm, and transmits it to the "local database".

Step 303, finding out the value corresponding to the key value by the local database according to different matching rules, wherein the key and the value are in one-to-one correspondence, encrypting the output value and storing the encrypted value in the local algorithm database.

Step 304, the encrypted Value is converted into a password for WiFi connection through an algorithm by the local algorithm library, and the password is encrypted through XXTea and output to the identification process.

Step 305, displaying the returned WiFi and the corresponding password in the identification process as free WiFi according to the returned WiFi and the corresponding password; if no password is returned, no free WiFi is displayed.

In step 303, the "local database" retrieves different value values according to different Key value matches, as shown in fig. 8. Different Key values correspond to different values, e.g., Key1 corresponds to value1, Key2 corresponds to value2, etc. Meanwhile, the lengths of the corresponding relations of different Key-values are different, and the risk that the local database is cracked by the explosion database can be greatly reduced through single matching and different relation lengths.
